Answer:
c=37
Step-by-step explanation:
Answer:
The smaller number is 15
Step-by-step explanation:
To find this, set up a proportion where the ratio is a fraction and the new value is with x on the other side.
3/7 = x/35
Now cross multiply to solve.
35 * 3 = 7 * x
105 = 7x
15 = x
Answer:
-20x-6y-16
Step-by-step explanation:
Answer:
Step-by-step explanation:
Volume of the box = x³ +11x² + 20x – 32 I think the ' is a typo for ³
the width is x-1 and the height is x+8
Find an expression for the length
Vol = LWH solve L
Vol / (WH) = L so
L = (x³ +11x² + 20x – 32) / (x-1) (x+8)
so it would help to factor the numerator
(x³ +11x² + 20x – 32) I'm willing to bet (x-1) and (x+8) are factors
but I will plot the equation to find the three roots
(x³ +11x² + 20x – 32) = (x-1) (x+8) (x+4)
L = (x³ +11x² + 20x – 32) / (x-1) (x+8)
= (x-1) (x+8) (x+4) / (x-1) (x+8) the (x-1) and (x+8) cancel out leaving
L = (x + 4)
5/12 times 3= 1.25, 1 25/100
1 1/4 is the answer
