Answer:
Store 1= $150
Store 2= $250
Step-by-step explanation:
Let the amount invested by store 1 be x while store 2 be y hence
10x-8y=1300 Eqn 1
Make x the subject of the formula for the first equation
10x=1300+8y divide both sides by 10
X=130+0.8y
6x+5y=2250 Eqn 2
Substituting where there’s x with 130+0.8y in equation 2 we obtain
6(130+0.8y)+5y=2250
780+4.8y+5y=2250
9.8y+780=2250
9.28y=2250-780=1470
Y=1470/9.8=150
X=130+0.8y= 130+0.8(150)=250
Answer:
A. I and IV
Step-by-step explanation:
I. 4(6 - x)
II. 4 + (6 - x)
III. 6(4 - x)
IV. (6 - x) + (6 - x) + (6 - x) + (6 - x)
Let's keep them in the simplest expressions.
I. 4(6 - x)
4(6) - 4x
24 - 4x
II. 4 + (6 - x)
4 + 6 - x
10 - x
III. 6(4 - x)
6(4) - 6x
24 - 6x
IV. (6 - x) + (6 - x) + (6 - x) + (6 - x)
6 - x + 6 - x + 6 - x + 6 - x
6 + 6 + 6 + 6 - x - x - x - x
24 - 4x
Only I and IV have the same result.
