Answer:
x = 6
Step-by-step explanation:
y varies inversely as x
y = k × 1/x. {where k is a constant}
when y = 3, x = 8
Therefore 3 = k/8 and k is 24
y = 24/x
When y = 4,
4 = 24/x
4x = 24
(dividing both sides by 4)
x = 6
Answer:
y=x+5
Step-by-step explanation:
There are infinite solutions to this problem and y=x+5 is one of them.
Substituting x=-2 and y=3 it checks out:
3=-2+5
3=3
Answer:
Jasmine ran last week 37.2 miles
Step-by-step explanation:
Let
x ----> number of miles Rob ran last week
y ----> number of miles Jasmine ran last week
we know that
x=y-27.2 ----> equation A
x=10 ----> equation B
Substitute equation B in equation A and solve for y
10=y-27.2
y=10+27.2
y=37.2 miles
