Answer:
y=4,x=1
Step-by-step explanation:
4x+y=8
x+y=5
subtract equation 2 from equation 1
3x + 0=3
3x=3
divide both sides by 3
x=1
substitute for x=1 in equation 2
x+y=5
1+y=5
y=5-1(collecting like terms)
y=4
Answer:
Square B 9 × 7.5
Step-by-step explanation:
The computation is shown below:
9 × 7 = 63 > 55
8 × 5 = 40 < 55
5 × 10 = 50 < 55
As it can be seen that in only one condition the total of square feet is less and in the other conditions the total of square feet is more
Therefore the option Square B is correct
And, the rest of the options are incorrect
The same to be considered
