Answer:
(5,4) is the solution
Step-by-step explanation:
2x + y = 14 --> y = -2x + 14
Substitute y = -2x + 14 into 3x - 2y = 7
3x - 2( -2x + 14) = 7
3x + 4x - 28 = 7
7x = 35
x = 5
y = -2(5) + 14
y = -10 + 14
y = 4
Answer (5 , 4)
3*5=15 15*8=120 Answer: 120m
I believe you have to do a cross product formula.
2174/x = 28.19/100
The denominator will tell how many parts it takes to make a whole
