y and x have a proportional relationship, and y = 25 when x = 60. What is the value of x when y = 30? 25, 36, 50, 72
2 answers:
Find the proportional relationship in a unit rate.
x:y
Put in x and y.
60:25
Divide both sides by 5.
12:5
So, every 5 units of y, there are 12 units of x.
Put the new y into proportion.
x:30
There are 5 extra units of y.
All you need to do is add 12 to the previous x.
60+12= 72
x=72

Answer:
20
Step-by-step explanation:
f = 2f - 20
f - 2f = - 20
- f = - 20
f = 20
Answer:
.76 x 10 or 7.6 x 10^0
Step-by-step explanation:
divide coefficients and subtract exponents
5.4 / 7.1 = .76
10^-7 / 10^-8 = 10
14 and 15
14^2 = 196
15^2 = 225
225+196 = 421

Answer:
-9/8
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
using (1,1) and (10,9)
m = (9 - 1)/(10 - 1)
m = (8)/(9)
m = 8/9
slope of line g is 8/9
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of h is -9/8
