Solve 4/9x+7=1/2.<br><br> Solve 1/8x−12=3/4.
Elenna [48]
\# 1 \\\\ \frac{4}{9}x+7=\frac{1}{2} \\\\ \frac{4x}{9}=\frac{1}{2}-7^{(2} \\\\ \frac{4x}{9}=\frac{1-14}{2} \\\\ \frac{4x}{9}=-\frac{13}{2} \\\\ 4x=-\frac{9*13}{2} \\\\ x=-\frac{\frac{9*13}{2}}{4} \\\\ x=-\frac{117}{2}*\frac{1}{4} \\\\ \boxed{x=-\frac{117}{8}=-14\frac{5}{8}}

\#2 \\\\ \frac{1}{8}x-12=\frac{3}{4} \\\\ \frac{1}{8}x=\frac{3}{4}+12^{(4} \\\\ \frac{x}{8}=\frac{3+48}{4} \\\\ \frac{x}{8}=\frac{51}{4} \\\\ x=\frac{\not8*51}{\not4} \\\\ x=2*51 \\\\ \boxed{x=102}

I need help with one and two
kozerog [31]

1) Angle T = 72°

Angle U = 54°

2) Angle M = 76°

Angle N = 76°

<em>Explanation</em><em>:</em><em> </em>

<em> </em> 1. Isosceles triangle (since 2 sides are equal)

Angle U = Angle S = 54° (equal sides of a traingle have equal angles)

angle U + angle S + angle T =180 (Angle sum Property)

54° + 54° + angle T = 180°

108 + angle T = 180°

Angle T = 180 - 108

= 72°

2. Isosceles triangle again (same properties)

angle L + angle M + angle N = 180

28 + angle M + angle N = 180

angle M + angle N = 180 - 28

angle M + angle N = 152

"angle M and N will be equal since it is

isosceles triangle"

so, 2x (M&N) = 152

x = 152 ÷ 2

= 76

therefore angle M = angle N = 76°
