To find x, replace y as 0 and solve. To find y, replace x with 0 and solve.
Answer:
20%
Step-by-step explanation:
An equation is 14=x/100*70 or 14=(x%)*70, either one works
solve for x:
- 14=x/100*70
- 14/70=x/100 (Divide each side by 70)
- 1/5=x/100 (Simplify 14/70)
- 100/5=x (Multiply each side by 100 to isolate x)
- x=20 (Simplify 100/5)
- 20% (Rewrite as a percent)
hope this helps!!
Answer:
36. m = (3/2)n
37. s = 5tv
38. c = 3/d
Step-by-step explanation:
Each of the variations in these problems has its own associated equation. You only need to make use of the given values to find the constant of variation (k) and fill in the equation.
- direct variation: y = kx; k = y/x
- joint variation: z = kxy; k = z/(xy)
- inverse variation: y = k/x; k = xy
_____
36. The constant for direct variation is the ratio of the given values:
k = m/n = 18/12 = 3/2
Then the equation for the direct variation is ...
m = (3/2)n
___
37. The constant for the joint variation is the expression ...
k = s/(tv) = 8/((4/5)·2) = 8/(8/5) = 8·5/8 = 5
Then the equation for the joint variation is ...
s = 5tv
___
38. The constant for the inverse variation is the product of the given values:
k = cd = (1/4)(12) = 3
Then the equation for the inverse variation is ...
c = 3/d
Answer: 24 $100 bills, even though this will add up to more than 2324 dollars, it is the amount needed to cover the price
Step-by-step explanation: divide 2324 dollars by 100
