Answer:
m= 4/5
Step-by-step explanation:
Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
It's not a multiple choice answer is it?
2(4*3) + 5.7*3 + 2(5.7*4)= 86.7 mm^2 (i could be wrong)
