Answer: x=64.
Step-by-step explanation:
48=3x/4
Multiply both sides by 4 : 192=3x
Divide both sides by 3. : x=64
Check: 64*3=192; 192/4=48 J=48 So x is 192.
Hope this helps! :p
Set up a ratio:
4 gallons / 30 plants = X gallons / 45 plants
Cross multiply:
4 * 45 = 30 * x
180 = 30x
Divide both sides by 30:
x = 180 / 30
x = 6
It would take 6 gallons.
Xy=k, whenever the product of two variables is a constant it is called inverse variation. This is an inverse relationship, intuitively because, as the value of one variable increases, the other decreases and vice versa.
It is easy to spot as xy=k or y=k/x.
Answer:
5
Step-by-step explanation:
insert f(-12) for f(x) and solve
f(-12)=|-12+7|
add -12 and 7
f(-12)=|-5|
absolute value makes it positive
f(-12)=5
Answer:
65 degrees
Step-by-step explanation:
65 degrees
it is 65 because of the vector relationship: 30 + 100 = 130. 130/2=65 degrees
