Answer:15
Step-by-step explanation: since it’s 4 to3 and if you multiply 4 and 5 you get 20 so you multiply 3 and 5 to get 15. Hope it helps!
Answer:
so far he has poured 38.4 grams
Step-by-step explanation:
2x^2 - 4 = 68
add 4 to both sides
2x^2 = 72
divide both sides by 2
x^2 = 36
find the square root of each sides
x = 6, -6
ANSWER: the positive value of x is 6
Answer:
Center = (5,-3) radius = sqrt (36) = 6
Step-by-step explanation:
Answer:
If y varies inversely as x, then we write it as:
y = k/x
where k is some constant.
If we multiply both sides of this equation by x we get an equation for k:
k = x*y
We are given that y=4 when x=7, therefore:
k = 7*4 = 28
Put this back into our original equation to get:
y = 28/x
