Answer:

I think his son is 12

Step-by-step explanation:

12 x 2 = 24

Step-by-step explanation:

x + 24

x + 2

x + 24 + 2 = x + 26

(x + 26)/(x + 2) = 2/1

x + 26 = 2x + 4

x = 22 years

The present age of the son is 22 years.

Let the age of the son after 2 years be x.

Then the age of the man after 2 years be 2x.

The present age of son = x - 2

The present age of man = 2x - 2

According to the question:

2x - 2 - (x - 2) = 24

x = 22 years

Answer:

The first one is -50.

The second one is -18.

Step-by-step explanation:

Answer:

-90

Step-by-step explanation:

You would need to input each x value from the table into your equation in order to find the output (y value)

f(9) = -9(9) - 9 = -90

f(0) = -9(0) - 9 = -9

f(7) = -9(7) - 9 = -72

f(4) = -9(4) - 9 = -45

f(-9) = -9(-9) - 9 = 72

After plugging in all of these numbers, of the answer choices given, -90 would be correctly found in the table.

Answer:

(d) -90

Step-by-step explanation:

The function can be simplified to ...

f(x) = -9(x +1)

This means any integer x will produce a y-value that is a multiple of 9. Among the answer choices, those are 90 and -90. We can try these to see if either of the x-values are in the table.

90 = -9(x +1)

-10 = x +1

-11 = x . . . . . not in the table

__

-90 = -9(x +1)

10 = x +1

9 = x . . . . . . . the first row of the table

The value -90 would be correctly found in the table.

we know the diameter of it is 2, so its radius must be half that, and the central angle is 5π/3, so

[tex]\textit{arc's length}\\\\ s=r\theta ~~ \begin{cases} r=radius\\ \theta =\stackrel{radians}{angle}\\[-0.5em] \hrulefill\\ r=1\\ \theta =\frac{5\pi }{3} \end{cases}\implies s=(1)(\frac{5\pi }{3})\implies s\approx 5.24~meters[/tex]

Solution:

[tex] \sqrt{4x + 13} = x + 2[/tex]

First square both sides.

[tex] = > ( \sqrt{4x + 13} ) ^{2} = (x + 2) ^{2} [/tex]

Now, square root and square gets cancel out in the LHS. And in the RHS, apply the identity: (a + b)² = a² + 2ab + b².

[tex] = > 4x + 13 = {(x)}^{2} + 2 \times x \times 2 + (2) ^{2} \\ = > 4x + 13 = {x}^{2} + 4x + 4[/tex]

Now, transpose 4x and 4 to LHS.

[tex] = > 4x - 4x + 13 - 4 = {x}^{2} \\ [/tex]

Now, do the addition and subtraction.

[tex] = > {x}^{2} = 9 \\ = > x = \sqrt{9} \\ = > x = ±3[/tex]

Answer:

The answer is D.

Step-by-step explanation:

For this question, you have to recall the properties of a triangle. Ergo, remember what a triangle is. Here are some of them.

1. A triangles has 3 sides, angles, and vertices.

2. All angles of a triangle add up to 180 degrees.

3. The sum of the length of any two sides of a triangle is greater than the length of the third side.

This third property of a triangle will help us solve the problem. Just do trial and error for these four answer choices and see which one fails this property. The only answer choice that fails is D because 3 + 5 = 8, and 8 < 9 (8 cannot be > 9).

AnsweI i think that the answer is 3a +a-15=225

Step-by-step explanation:

because your substituting B(a-15) into the first equation

The value of a and b for the given systems of linear equations will be 7.5 and -7.5.

What is the equation?

A mathematical equation asserts the equality of two expressions, which may or may not contain variables or integers. Equations are fundamental concerns and attempts to methodically resolve these concerns have served as the primary driving forces behind the creation of mathematics.

It is given that, the given linear equations are,

3a+b=225 -----------(1)

b=a-15 ---------------(2)

In order to solve the linear equations put the value of b from equation 2 in equation 1 as,

3a+b=225

3a+(a-15)=15

3a+a-15=15

4a=15+15

4a=30

a=30/4

a=7.5

Put the value of a in equation 2 to obtain b as

b=a-15

b=7.5-15

b= -7.5

Thus, the value of a and b for the given systems of linear equations will be 7.5 and -7.5.

Answer:

Slope is -6/7

Step-by-step explanation:

(See attachment below)

The slope of the line in simplest form is -7/20.

What is slope?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

Using the Slope Equation

Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

Given that a line representing the "rise" and a line representing the "run" of the line.

Here,

y1 = 7 x1 = -10

y2 = 0 x2 = 10

Slope of line = (y2 - y1) ÷ (x2 - x1)

= (0 - 7) ÷ [10 - (-10)]

= -7 ÷ 20

= -7/20

Hence, The slope of the line in simplest form is -7/20.

Answer:

20 yards

Step-by-step explanation:

21 + x = perimeter (x being the width because it is unknown)

so far this would look like an incomplete triangle, or in other words, it is connected to Pythagoras theorem.

a^2 +b^2 = c^2 but since we don't know one of the sides of the triangle, (a^2 in this case) we can reverse the equation to get our answer.

=

c^2 - b^2 = a^2

c would represent the 2 holes the gophers dig on opposite sides of the rectangular yard, and since we already know the length, we can use this equation.

c = 29

b = 21

a = x (unknown)

=

29^2 - 21^2 = x^2

now we can just square c (29) and b (21)

29^2 = 841

21^2 = 441

so now the equation looks like

841 - 441 = x^2

now just some simple subtraction

841 - 441 = 400

so...

400 = x^2

and then to get x without the ^2 we can just get the square root of 400, which counters the ^2.

=

√400 = 20

so there you have it!

20 = x

or

20 = a

or

20 = the width!

there is probably a better way to do this, but I just like geometry lol.

Explanation:

We know that Gianna has completed 30 sit-ups, which is 20% of her goal. To find her goal, we will need to change the 20% to a 100%. The 100% means that she has achieved her goal. To do this, we can write an equation. However, since 20 is divisible by 100, we will solve this problem with a shorter way.

Solution:

30 sit-ups = 20% goal finished=> 30 x 5 sit-ups = 20 x 5% goal finished=> 150 sit-ups = 100% goal finished

Final Answer:

This means that Gianna's goal is to reach 150 sit-ups.

Answer:

150 situps

Step-by-step explanation:

I think the best way to solve these types of problems in conceptually. If Gianna has only done 20% of her goal, we can ask ourselves by what number can we multiply 20% by to get 100%. In this case it is 5.

This equation looks like 5 x 20% = 100%

So, now that we know a factor of 5 will get us to Gianna's total goal, we just need to multiply the 30 situps she has already done by 5 and we will get 150 situps.

This could also be solved by setting up a conversion. which would look like:

30 situps/ 20% = ? number of situps/ 100%

Now solve for the ? number of situps. You can treat the percentages as regular whole numbers.

Either way will give you the answer of 150 situps.

(a) (4, 5)

Step-by-step explanation:

The point-slope form of the equation for a line is ...

y -k = m(x -h) . . . . . . where m is the slope and (h, k) is the point

Comparing this to

y -5 = 1/2(x -4)

we see that k=5, m=1/2, h=4. Then the point is ...

(h, k) = (4, 5)

Answer:

the exact form is 3 11/16. but if you were to estimate you could say 4, since 11 4/5 is very close to 12 and you are dividing that by 3 1/5 which is almost 3

Answer:

B) 1:3

Step-by-step explanation:

Let's layout the information given firstly.

Marigolds= 18

Petunias= 6

In ratios, you need to follow the arrangement, for say in this question they say petunias go first, so the ratio should involve the value 6 first.

Therefore, it will give you, 6:18.

Now, you need to simplify this ratio. Just simplify it as it were, a fraction. Divide each number by a common factor, in this case, it is 6. Once you've done that, you'll get 1:3.
