Answer:
the actual total is 722 so maybe 700 since it's closer
Step-by-step explanation:
Answer:
-23
Step-by-step explanation:
you calculate 49-|6-14|x 9
you then calculate the absolute value
49-|-8|x 9
then multiply the numbers
49-8 x 9
calculate those numbers
49 - 72
your solution will be -23
Answer:
200
Step-by-step explanation:
Use the ratio: 20/100 = 40/X
Simplify the ratio: 1/5 = 40/X
Cross Multiply: 1X = 200
Divide both sides by 1: 1X/1 = 200/1
Simplify: X = 200
The answer is 1:2. all you have to do is add the dots for example 4/5 would be 4:5
Answer:
A
Step-by-step explanation:
given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
to find k use the given condition y = 2 when x = 10
k = 
= 
= 
y = x ← equation of variation
when x = 40, then
y = × 40 = 8 → A
