3(x - 5) – 3 = 5(x - 2) + 2x
1 answer:
Answer:
x=−2
Step-by-step explanation: Step 1: Simplify both sides of the equation.
3(x−5)−3=5(x−2)+2x
(3)(x)+(3)(−5)+−3=(5)(x)+(5)(−2)+2x(Distribute)
3x+−15+−3=5x+−10+2x
(3x)+(−15+−3)=(5x+2x)+(−10)(Combine Like Terms)
3x+−18=7x+−10
3x−18=7x−10
Step 2: Subtract 7x from both sides.
3x−18−7x=7x−10−7x
−4x−18=−10
Step 3: Add 18 to both sides.
−4x−18+18=−10+18
−4x=8
Step 4: Divide both sides by -4.
−4x
−4
=
8

Answer:
MP=(0.5,4.5)
Step-by-step explanation:
USE THIS FORMULA:
M=(x1+x2/2,y1+y2/2)
14,800=60x+16y
x+y=441
that implies y=441-x so
14,800=60x+16(441-x)
14,800=60x+16*441-16x
14,800-16*441=44x
7744=44x
x=176 kids and 441-176 adults
Answer:
Step-by-step explanation:
For independent events,
P(AB)=P(A)orP(B)
= P(A)uP(B)
=P(A)×P(B)
= 0.55×0.72
P(AB)=0.396
Step-by-step explanation:
A. 2(10)-(-10)
20 -(-10) -------> (-)×(-) =(+)
20 + 10
30
B.29 + 1
30
Area of trapezoid = (B1 + B2)h/2
B1 = 15 in. + 4 in. + 6 in. = 25 in.
B2 = 15 in.
h = 7 in.
Area = (25 in. + 15 in.)(7 in.)/2 = 140 in.^2
