Don't Know How To Do Thissimplify Each Expression By Combining Terms

Answers

Answer 1

Answer:

Combining like terms is actually pretty straightforward, you just have to combine like terms. In the problem 5c+2c, it would equal 7c since c is a common variable in this equation.

In the next question 16p+5+p-3x+6-x, it would equal 17p-4x+11 because 16p+p is 17p, -3x-x is -4x, and 5+6 equals to 11.

In the third question 18p+3-8p-5 would equal to 10p-2 since 18p-8p equals to 10p, and 3-5 equals to -2.

In the last question 9u+11v-22u+12v, it would equal to -13u+23v because 9u-22u equals to -13, and 11v+12v is 23v.

I hope this helped you!

Answer 2

A car travels 625.68 miles and uses 9.9 gallons of gas. What is the unit rate for gas?

Answers

Let’s make this into an expression then. Huh. A mile for a 16 thousandth of gas. You must have a pretty good car, dude.

Answer:

63.2:1

Step-by-step explanation:

We can find the unit rate by making equations that will help us solve.

We need to find how many miles the car travels in one gallon.

We can divide 625.68 by 9.9.

625.68/9.9 = 63.2

The car travels 63.2 miles on one gallon of gas.

Meaning that the unit rate is 63.2:1.

Hope this helps. Have a nice day.

Answer: x=40 y=140

Step-by-step explanation:

To work out x:

The angles in a triangle always add up to 180.

You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.

To work out y:

Angles on a straight also add up to 180.

So as you have figured out what x is (40) you would take it away from 180 to give you y.

180-40=140

Hope this helps :)

A, since Jada is higher than Diego, who is higher than Lin
The answer is a and c your welcome

I have a lot more questions like this.

Answers

Answer:

A

Step-by-step explanation:

Diego has $10 and begins saving $2 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $50 and begins spending $2 per week on supplies for her art class. Is there a week when they have the same amount of money?Write an equation and answer.

Answers

Answer:

no

Step-by-step explanation:

the easiest way to find out is to plot these on a graph

for Diego's function, we will write the total amount of savings (or his goal) = the amount hes saving multiplied by the weeks he saves + the amount he started with

y = 2x + 10 (in blue in attached file)

same with Lin

y = 2x + 50 (in red in attached file)

if the lines cross at any point, then that point on the two lines is the same value of x AND y, otherwise, one or the other is a different value

beings as these two lines have the same rate of change, they will not cross, meaning that neither will have the same amount if the rate continues

yes
on week 11 they will both have $30

On a balanced scale are a 25-g mass, a 100-g mass, and five identical blocks marked X as shown. What is the mass of each block marked X? Write an equation illustrated by this balanced scale. I really need help with this.

Answers

Answer:

One block - 15

Two blocks - 30

Three blocks - 45

Four blocks - 60

Five blocks - 75

Equation: 25 + 5x = 100

Step-by-step explanation:

This is a pretty simple problem. The scale is balanced and from what we know, the 100 and 25 are on different sides. If we want the scale to be balanced, then we have to solve the equation:

25 + 5x = 100.

(We have the 5x because we have 5 blocks that are marked as x)

subtract 25 from both sides

25-25 + 5x = 100-25

5x = 75

the following step is to divide both sides by 5.

5x/5 = 75/5

x = 15

Now that the equation is solved, we know that ONE blocked marked as X equals 15-g.

(All five of them equal 75-g)
