Answer:
3
Step-by-step explanation:
Convert to improper fractions:
4 1/2 = 9/2
1 1/2 = 3/2
Find the reciprocal:
9/2 / 3/2 = 9/2 x 2/3
Multiply:
9/2 x 2/3 = 18/6
Simplify:
18/6 = 3
P = 2l + 2w
P = 2(8.4) + 2(4.8)
P = 16.8 + 9.6
P = 26.4cm
R = S = 82
360 - 82 - 82 = 196
196/2 = 98
Q = T = 98
−10x+5y=10
x−5y=−28
Rewrite equations:
x−5y=−28
−10x+5y=10
Step: Solve:
x−5y=−28
x−5y+5y=−28+5y(Add 5y to both sides)
x=5y−28
Step: Substitute:
−10x+5y=10
−10(5y−28)+5y=10
−45y+280=10(Simplify both sides of the equation)
−45y+280+−280=10+−280(Add -280 to both sides)
−45y=−270
−45y
−45
=
−270
−45
(Divide both sides by -45)
y=6
Step: Substitute:
x=5y−28
x=(5)(6)−28
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=6
