Answer:
x = 44/19, y = 33/20
Step-by-step explanation:
Multiply the first eq by 18, to get:
90/y - 36/x = 39
so 36/x = 90/y - 39
in this form we can plug it into the second eq:
90/y - 39 - 24/y = 1 =>
66/y = 40 =>
y = 66/40 = 33/20
Fill that in the first:
100/33 - 2/x = 13/6 =>
200/66 - 143/66 = 2/x =>
57/66 = 2/x =>
57x = 2*66
x = 132/57 = 44/19
Answer:
The number is 79
Step-by-step explanation:
Let the number be 'x'
x + 17 = 96
Subtract 17 from both sides,
x + 17 -17 = 96 - 17
<h3> x = 79</h3>
Answer:
8
Step-by-step explanation:
b(0.5) = 4
b = 4/0.5
b = 8
The system equation is: D.
0.10*d+0.25*q=3.55
d=4+2*q
where d= dimes and q=quarters
0.10* (4+2*q)+0.25*q=3.55
0.40+0.2*q+0.25*q=3.55
0.45*q=3.15
q=3.15/0.45 = 7
d=4+2*7=14+4=18
Answer:
X = 1 3/4
