The third option is correct
7/8=x/48
x=(7/8)48
x=(7)(48/8)
x=(7)(6)
x=42
D.42
(1) 2 of one step equations
x - 23 = 8
x - 23 + 23 = 8 + 23
x = 31
n + 2 = 9
n + 2 - 2 = 9 - 2
n = 7
(2) 2 equations with fractions
3/4 (x + 3) = 9
4 [ 3/4 (x + 3) ] = 4[9]
3 (x + 3) = 36
3x + 9 - 9 = 36 - 9
3x/3 = 27/3
1/3 x 3/4
cross multiply
so 3/12 and simplify which makes it
1/4
(3) distributive property
3(2 + 4) = (3 • 2) + (3 • 4)
3(6) = 6 + 12
18 = 18

area of parallelogram: base × height = 17.6 cm sq
⇒ 4 × h = 17.6
⇒ h = 17.6/4
⇒ h = 4.4 cm
Step-by-step explanation:
Step-by-step explanation:
A. to make the quadrilateral a parallelogram, we have:
7y + 5 = 8y - 4
112 = 10x - 8
<=> y = 5 + 4
120 = 10x
<=> x = 12
y = 9
B.we have:
17 = 4x + 5
63 = 8y - 1
<=> 12 = 4x
64 = 8y
<=> x = 3
y = 8
