2(9x-1)+7(x+6)=-60
Reorder the terms in parentheses
+(+18x-2)+7*(x+6)=-60
Remove unnecessary parentheses
+18x-2+7*(+x+6)=-60
Reorder the terms in parentheses
+18x-2+(+7x+42)=-60
Remove unnecessary parentheses
+18x-2+7x+42=-60
We move all terms containing x to the left and all other terms to the right
+18x+7x=-60+2-42
We simplify left and right side of the equation
+25x=-100
We divide both sides of the equation by 25 to get x
x=-100/25
x=-4
Yes you are correct with that answer
Hi there!
We can split into factors using the "guess and check" method.
Factors are in the format of:
(ax + b)(cx + d), where in this instance:
a · c = 2
bc + da = 5
b · d = 3
Thus, we get:
(2x + 3)(x + 1)
$140 was the original price.
<u>discount</u> : 45%
45% ⇒ $63
1% ⇒ $(63/45)
1% ⇒ $1.4
<u>original price is always 100%</u>
100% ⇒ $(1.4*100)
100% ⇒ $140
Answer:
100
Step-by-step explanation:
we need to swap sides so we take the 320 and put it in the other side but in negative form and that comes out to 1800 and then we divide that by 18
