2 : x
17 : 102
Cross multiply.
17x = 204
Solve for x; how many batches for 102 people.
17x=204
X = 12
She needs to make 12 batches
B. -3 and 5
constants are the numbers without variables (the letters) and coefficients are the numbers with variables
Answer:
x = 15
Step-by-step explanation:
The sum of the angles in a triangle is 180º
3x + 5x + 4x = 180
Combine like terms
12x = 180
Divide both sides by 12
x = 15
C = 5x
C = 5 * 15
C = 75º
Answer:
Step-by-step explanation:
use these two equations
A: y = 15
B: y = 2r + 5
a) set the equations equal to eachother for your first answer
15 = 2r + 5
B) solve for r
15 = 2r + 5
10 = 2r
5 = r
after 5 rides the cost will be the same
