Answer:
x = 10 , y = 15
Step-by-step explanation:
8x - 10 and 7x are alternate angles and are congruent , then
8x - 10 = 7x ( subtract 7x from both sides )
x - 10 = 0 ( add 10 to both sides )
x = 10
Then
8x - 10 = 8(10) - 10 = 80 - 10 = 70
6y + 20 and 8x - 10 are same- side interior angles and sum to 180°, that is
6y + 20 + 70 = 180
6y + 90 = 180 ( subtract 90 from both sides )
6y = 90 ( divide both sides by 6 )
y = 15

Answer:
Step-by-step explanation:
let x be the number.
9x+16≥-26
9x≥-26-16
9x≥-42
3x≥-14
x≥-14/3
Answer:
Step-by-step explanation:
The most important part of this question is the estimation. That means you round either up or down to get whole numbers.
You can make - 37.44 either - 40 or - 35
You can make 4.8 into 5
So the answer should lie between -40/5 = - 8
or
The answer should be between - 35/5 = - 7
Use your calculator to check it.
-37.44 ÷ 4.8 = - 7.8
This skill is very handy when shopping or writing a test. It you get an outrageous answer like - 21.44 you know you have done something wrong.
Answer:
10 ft by 10 ft by 10 ft works, but there are other solutions.
Step-by-step explanation:
There are many solutions.
One solution is 10 ft by 10 ft by 10 ft.
The volume then is:
10 ft * 10 ft * 10 ft = 1000 ft^3
