Answers

Answer 1

Answer:

.

Step-by-step explanation:

.

Answer 2

Answer:

[tex]4 \frac{1}{2} [/tex]

Step-by-step explanation:

Let's find the value of x first.

From the first sentence:

4x +13= 8

Subtract 13 from both sides:

4x= 8 -13

4x= -5

[tex]x = - \frac{5}{4} [/tex]

[tex]x = - 1 \frac{1}{4} [/tex]

2 times x is added to 7 → 2x +7

2x +7

[tex]= 2( - \frac{5}{4} ) + 7 [/tex]

[tex] = - \frac{5}{2} + 7[/tex]

[tex] = 4 \frac{1}{2} [/tex]

15.Solve the equation, then choose the correct answer:
–4(x – 3) = –8

Answers

Answer:

x = 5

Step-by-step explanation:

-4 ( x - 3) = -8

-4x +12 = -8

-4x = -20

x = 5

Answer:
-20

Explanation:
Distribute first
-4x + 12 = -8
Subtract 12 on both sides
-4x +12 = -8
-12 -12
-4x = -20
Divide by -4 on both sides
-4x = -20
/-4 /-4
x = 5

Juan's pit crew was able to get his car back onto the racetrack 0.4 seconds faster than Paul's crew. Paul's crew took 1.3 seconds longer than Terry's crew. Terry's crew took 5.8 seconds to complete their pit stop. How long did Juan's crew take?

Answers

Answer:

6.7 seconds

Step-by-step explanation:

Juan= Paul-0.4

Paul=Terry+1.3

We can substitute Terry+1.3 for Paul since they are equal

juan=(Terry-0.4)+1.3

terry=5.8

juan=(5.8-0.4)+1.3

juan=6.7

The rectangular prism has a volume of 936 cubic inches. Write and solve an equation to find the missing dimension of the prism.

Answers

Step-by-step explanation:

A rectangular prism is nothing but a cuboid. Let the length , width and height of the  rectangular prism be l, w and h.

We know that volume of a cuboid V = l×w×h

So,  l×w×h = 936

So, we can find any dimension of the prism provided the the other two dimensions are given to us.

11. The ratio of men to women at a track meet is 4:5. If there are 20 men at the meet, use a proportion to determine how many people are at the meet.​

Answers

Answer:

There are 36 people at the meet

Step-by-step explanation:

if the ratio is 4 men to 5 women it means that every time there are 4 men there will be 5 women so its 4/5

and since we know there are 20 men the equation becomes:

4/5 = x/20

so to make 4/5 have 20 as a denominator we multiply by 4/4.

4/5*4/4 = 16/20

So, now we know there are 16 women.

And 16+20 = 36

Answer:

QX = 5.7 units

Step-by-step explanation:

Here, we want to find the value of QX

let us call this h

For a rectangle, the parallel sides have equal side lengths, and the angle at each corner is a right angle

Since X is the midpoint of SR, then XR is 1/2 * 8 = 4

So we have an isosceles right triangle in QXR, with QX as the hypotenuse since it is the side that faces the right triangle

Mathematically, for a right triangle, the square of the hypotenuse equals the sum of the squares of the two other sides

Thus;

h^2 = 4^2 + 4^2

h^2 = 16 + 16

h^2 = 32

h = √32

h = 5.7
