<u>Answer</u>
C = 12
<u>Explanation</u>
Ratio is a division. For the two ratios to be proportional, then they must be the same after been simplified to their simplest form.
7/C = 35/60
35 has been divided by 5 to get 7. 60 must also be dived by 5 for the ratios to be proportional.
60 ÷ 5 = 12
∴ C = 12.
7/12 = 35/60
Answer:
C
Step-by-step explanation:
the only it has constant rate of change (slope, gradient or derivative at every point is equal)
Step-by-step explanation:
I guess the answer is 187MB
9x - 8y = -11
-9x + 3y = 21
Add the second equation
9x - 8y = -11
+ (-9x) + 3y = 21
-5y = 10
divide both sides by -5
y = -2
substitute y into one of the two equations in the beginning
9x - 8(-2) = -11
9x + 16 = -11
subtract 16 on both sides
9x = -27
divide both sides by 9
x = -3
The answer is (-3, -2)
x = -3
y = -2
Answer:
S = 4
Step-by-step explanation:
In a 45-45-90 right triangle, the legs are equal because the angles are equal.
