Answer: x=-1
Step-by-step explanation:
8-3x-x=12
-3x-x=-4x
8-4x=12
-8 -8
-4x=4
-4x/-4=4/-4
x=-1
Answer:
C. One hundred twenty-five inches cubed
Step-by-step explanation:
To find the answer,
The volume of a cube is side * side * side
In a cube all the sides are the same.
5 * 5 * 5 = 125
<span>4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
</span>Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9
<span>
x = - b </span>± √Δ / 2.a



A. Two real solutions (x' = -1 and x'' = -1/4)
Answer:
2 quarters and 5 dimes
Step-by-step explanation:
(2) 25 cent coins = 50 cents
(5) 10 cent coins = 50 cents
equals $1
I got x=185
0.75(185)-18.50=0.65(185)
120.25=120.25
