Hey there!

Answer:\boxed{x=-9}

Explanation:

2x+20=-3x-25

2x+20+3x=-3x-25+3x\\5x+20=-25 Add 3x to both sides

5x+20-20=-25-20\\5x=-45 Subtract 20 to both sides

\frac{5x}{5}=\frac{-45}{5} Divide both sides by 5

x=-9

Hope this helps!

A clothing truck is shaped like a rectangular prism. The volume of the truck 15 ft cubed. The area of the base of the container
Ghella [55]

Answer: 2.5 ft

Step-by-step explanation:

The volume of a rectangular prism is given by the following formula:

V=(l)(w)(h) (1)

Where:

l is the length of the base

w is the width of the base

h is the height of the prism

On the other hand, tha area of a rectangle is:

A=(l)(w) (2)

Then, we can rewrite (1) in terms of (2):

V=(A)(h) (3)

Now, we know the value of the volume and the area of the base:

V=15ft^{3}

A=6ft^{2}

Substituting these values in (3):

15ft^{3}=(6ft^{2})(h) (4)

Isolating h:

h=2.5 ft This is the height of the truck

​Together, teammates Pedro and Ricky got 2673 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each
ioda

Answer:

Pedro got 1520 base hits and Ricky got 1243.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of base hits that Pedro got.

y is the number of base hits that Ricky got.

Pedro and Ricky got 2673 base hits last season.

This means that x + y = 2763

Pedro had 277 more hits than Ricky.

This means that x = y + 277

Replacing in the first equation

x + y = 2763

y + 277 + y = 2763

2y = 2486

y = \frac{2486}{2}

y = 1243

x = y + 277 = 1243 + 277 = 1520

Pedro got 1520 base hits and Ricky got 1243.

Solve the following equation for x: 6(4x+ 1) = 3(x + 8) + 3.
salantis [7]

Answer:

x = -1/7  Or 0.143 (3 dec)

Step-by-step explanation:

6(4x + 5) = 3(x + 8) + 3  

= 24x + 30 = 3x + 24 + 3  

24x + 30 = 3x + 27  

21x + 30 = 27

21x = -3  

21x/21 = -3/21  

x = -1/7

Or 0.143 (3 dec)
