To put this into simpler terms, well simplier for me anyways, Emma is dividing 9 inches of paper into 2/5, or .4, inches of paper.
That being said, we now just need to divide 9 by 2/5 or .4
We get 22.5
So Emma will be able to make 22 strips since we can't have half a strip. (Well, we could, but it would be small than what we need)
Any questions?
Answer:
y = 182
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 112 when x = 8
k = 
= 
= 14
y = 14x ← equation of variation
When x = 13, then
y = 14 × 13 = 182
Answer:
27=3c-3(6-2c)
Open the brackets (multiply 6 and -2c by -3)
27=3c-18+6c
Add 3c and 6c
27=9c-18
Add 18 to both sides
45=9c
Divide by 9
c=5 (45/9)
now to check this just substitute c (5) into the equation
27=(3*5)-18+(6*5)
27=15-18+30
27=30-3
27=27
