(-4x7)/10 = -28/10 = -14/5

-19/2 ÷ 38/7 <=> -19/2 x 7/38 and simplify = -7/4
The measure of ∠1 is also <span>93° because vertically opposite angles are equal.</span>
Answer:
35
Step-by-step explanation:
x-18=y
y*-3=-51
y=17
x-18=17
17+18=x
x=35
move the decimal point 2 places to the left
42.6 /
= 0.426
Answer:
13 units
Step-by-step explanation:
The legs of an isosceles trapezoid are congruent, then
x + 8 = 48 - 7x ( add 7x to both sides )
8x + 8 = 48 ( subtract 8 from both sides )
8x = 40 ( divide both sides by 8 )
x = 5
Then
leg = x + 8 = 5 + 8 = 13
