Zigmanuir [339]

Answer:

  • Melissa: 30
  • Ryan: 23
  • Chau: 69

Step-by-step explanation:

Let r represent the number of messages Ryan sent. Then Chau sent 3r and Melissa sent r+7. Their total was ...

  (r+7) +(r) +(3r) = 122

  5r +7 = 122 . . . . . collect terms

  5r = 115 . . . . . . . . subtract 7

  r = 23 . . . . . . . . . . divide by 5

Ryan sent 23, Melissa sent 30, and Chau sent 69 text messages.

George Kittle was given 300 protein bars. He eats 4 of them every day. Write an equation that represents the situation if he has
nikklg [1K]

Answer:

Part 1) The linear equation is y=-4x+300

Part 2) if he has 90 protein bars left, then 52.5 days have passed

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

y is the number of protein bars left

x is the number of days

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope is equal to

m=-4\ \frac{bars}{day} ----> is negative because is a decreasing function

b=300\ protein\ bars

substitute

y=-4x+300  ---> linear equation that represent this situation

If he has 90 protein bars left

so

For y=90

substitute in the linear equation and solve for x

90=-4x+300\\4x=300-90\\4x=210\\x=52.5\ days

therefore

if he has 90 protein bars left, then 52.5 days have passed

ziro4ka [17]

Answer:

True.

Step-by-step explanation:

The artists is using simple math. When cutting squares from the corners he uses the same measure for each side of the figuer (because is a square) and the remaining sides thatare folded havethe same measures as the squares.

Cutting each side with the correct percent of the total surface in order to go from 20 in to 15 in.

What is the value of x, when 10(x + 2) = 5(x + 8)?
inna [77]
10 (x + 2) = 5 (x + 8)

First, we can start off by dividing each side by 5. Each side usually meaning, the whole number in front of the parentheses, in simpler words. 10 ÷ 5 = 2 and 5 ÷ 5 = 1, which can be represented as a variable (x).
2(x + 2) = x + 8

Second, we can now expand our problem. Basically, remove parentheses. We're focusing on the left side of the problem right now, so to expand 2(x + 2), we could combine 2 and the variable to create 2x, and multiply 2 times 2, which equals 4.
2x + 4 = x + 8

Third, our next step is to subtract 4 from each side. Now all we are trying to do is get the variable to equal something by itself.
2x = x + 8 - 4

Fourth, let's simplify the right side of the problem now. x + 8 - 4, we would start of by subtracting 8 - 4, which equals 4 and leave the variable alone.
2x = x + 4

Fifth, subtract the variable (x) from each side. You will get the problem to look like: 2x - x = 4. We can now simplify 2x - x, which equals x.
x = 4

Answer: \fbox {x = 4}
