Answer:

-36

Step-by-step explanation:

‐13−23= ‐13 + (-23) =  -36

Both 13 and  23 have negative sign. So if two numbers have the same sign, we have to add and put the same sign.

A 32-ft pipe must be cut into three pieces. The longest piece will be twice as long as the shortest piece, and the medium-sized
True [87]

Answer:

7, 11, 14 feet from shortest to longest

Step-by-step explanation:

Let's say that the shortest pipe is equal to x, and work from there.

The medium size piece is 4 feet longer than the shortest piece, so it is equal to 4+x

The longest piece is twice as long as the shortest piece, so it is equal to 2 * x.

The three pieces added up make up the 32 feet pipe, so we can write this as

(2*x) + (4+x) + x = 32

2*x + 4 + x + x = 32

4 * x + 4 = 32

subtract 4 from both sides to isolate the x and its coefficient

4 * x = 28

divide both sides by 4 to isolate the x

x= 7

Therefore, the shortest piece is x=7 feet long. The medium piece is x+4=11 feet long, and the longest piece is x*2=14 feet long

Fairview High School has a total of 92 boys and girls who play sports. If the number of boys is 17 more than twice the number of
MaRussiya [10]
Girls = x
boys = y

y = 92 - x
y = 17 + 2x

y = 92 - x
-y= -17 - 2x
0 = 75 - 3x
3x = 75
x = 25

25 girls play sports at the school
y = 92 - 25
y = 67

67 boys play sports at the school
