Answer: 83.3
Step-by-step explanation:
0.98 x 85 =83.3
Answer:
6.3
Step-by-step explanation:
10.5 : 5 = x : 3
5x = 3 x 10.5 = 31.5
x = 6.3
32/a = a/2
a^2 = 64
a = 8
b^2 = 8^2 + 2^2
b^2 = 64 + 4
b^2 = 68
b = 2√17
answer is the first option
a = 8, b = 2√17
8 + _ = 10
10 - 8 = 2
8 + 2 = 10
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
