Answer:
x = 
Step-by-step explanation:
7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6
Multiply both sides by 10:
7.4x×10+4.1(2x-4)×10=-2.3(x-6)×10-21.6×10
Refine:
74x+41(2x-4)=-23(x-6)-216
Distributive Property:
74x+82x-164=-23(x-6)-216
Combine like terms:
156x-164=-23(x-6)-216
Distributive Property:
156x-164=-23x+138-216
Combine like terms:
156x-164=-23x-78
Add 164 to both sides:
156x-164+164=-23x-78+164
Simplify:
156x=-23x+86
Add 23x to both sides:
156x+23x=-23x+86+23x
Simplify:
179x=86
Divide both sides by 179:
=
Simplify:
x =
24/15 is the initial fraction. Divide both the numerator and denominator by 3 to get the answer: 8/5
The number provided rounded to the nearest tenth is 13.2.
Because the number in the hundreds place is a 4, we round down and keep the tenth at 2.
Step-by-step explanation:
3x2 -5x+1=0
Quadratic eq ax2 +bx+c=0

=13>0 so 2 solutions.
Answer:
Step 1: Find f(5/2)
f(5/2) = -23(5/2) + 5
f(5/2) = -115/2 + 5
<em><u>f(5/2) = -105/2</u></em>
<em><u /></em>
<em><u /></em>
Step 2: Find f(52)
f(52) = -23(52) + 5
f(52) = -1196 + 5
<em><u>f(52) = -1,191</u></em>
