Answer 1

Answer:

Answer:

5x +2y =38

5(6) +2y = 38

30 +2y= 38

2y= 8

y= 4

(6, 4)

5(0) +2y =38

2y= 38

y= 19

(0,19)

5(-2) +2y= 38

-10 +2y =38

2y= 48

y=24

(-2,24)

Six times the sum of a number and eight is 30. Find the number

Answers

Answer:

-3

Step-by-step explanation:

to the following equation:

6(x + 8) = 30

Now, we need to solve this equation for x. First, distribute the 6 on the left side of the equation:

6x + 48 = 30

Next, isolate the variable x by subtracting 48 from both sides of the equation:

6x = 30 - 48

6x = -18

Finally, divide both sides by 6 to solve for x:

x = -18 / 6

x = -3

So, the number is -3.

A ten-foot-long board is cut into three pieces. The second piece is half as long as the first. The third piece is 4 feet longer than the second. How long is the first piece?

Answers

Let's say the second piece is x ft long
The first piece is 2x ft long
The third piece is x+4 ft long
All of the pieces should add up to 10ft
x+2x+x+4=10
4x= 6
x=1.5ft
The first piece is 2x ft long=3 ft long
