Answer:
55-15=40 is the correct answer
Y varies directly with x" means y = constant * x or y = kx ----- (1)1. when x = -1/2, y = 2Put it in (1):2 = k * (-1/2)multiply by 2:4 = k * (-1)4 = -kk = -4y = -4x
"find the value of y when x= -0.3"y = -4x = (-4) * (-0.3) = 1.2
So for each problem, start with y = kxThey give you one x and one y value.Put it in y = kx and find k.Then put x = -0.3 and find y.
Answer:
Step-by-step explanation:
19 bananas =1 watermelon
3 pineapples =1 watermelon
Then
<u>19 bananas = 3 pineapples</u>
1 pineapple = 3 grapes,
then
<u>3 pineapples = 9 grapes</u>
3 pineapples = 9 grapes
19 bananas = 3 pineapples
then
<u>9 grapes = 19 bananas</u>
9 grapes = 19 bananas
x grapes = 4 bananas
Write a proportion:
Cross multiply
8 is in the thousands place.
Look to the number in the hundreds (right next to it). It is a 4. Because 4 is less than 5, round down.
68413 rounded down in the thousands place becomes 68000
68000 is your answer
hope this helps
