Answer:
<em><u>120</u></em>
Step-by-step explanation:
10 times 8 times 1.5 equals <u><em>120</em></u>
Insert x = 7
so 3/(7+2) - sqr (7-3)
=3 / (9) - sqr (4)
= 1/3 - 2
=1/3 - 6/3
= -5/3
Answer:
x + 4y = 51
x = -4y + 51
Substitution
-3(-4y + 51) + 5y = 85
Distribution
12y - 153 + 5y = 85
Combine like terms
17y = 238
y = 14
x = -4(14) + 51
x = -7
