Answer:
hello rspl social science sample paper chaye
you cant on brainly only type but put points on the corners and draw that line on the oposite
A - avocados, G - grapes, K - kiwis.
We know that: A = 3G, K = A - 0.75
So: G = A / 3
A + G + K = 16.75
A + A/3 + A - 0.75 = 16.75
7/3 A = 16.75 + 0.75
7/3 A = 17.50
A = 17.50 : 7/3
A = $7.50
G = 7.50 : 3 = $2.50
K = 7.50 - 0.75 = $6.75
Answer:
Prices of the fruits are A = $7.50, G = $2.50 and K = $6.75.
Answer:
r = 16
Step-by-step explanation:
Cross multiply:
4 x 20 = r x 5
Simplifying
4 x 20 = r x 5
Multiply 4 x 20
80 = r x 5
Reorder the terms for easier multiplication:
80 = 5r
Solve
80 = 5r
Solve for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-5r' to each side of the equation.
80 + -5r = 5r + -5r
Combine like terms: 5r + -5r = 0
80 + -5r = 0
Add '-80' to each side of the equation.
80 + -80 + -5r = 0 + -80
Combine like terms: 80 + -80 = 0
0 + -5r = 0 + -80
-5r = 0 + -80
Combine like terms: 0 + -80 = -80
-5r = -80
Divide each side by '-5'.
r = 16
Simplify
r = 16
