Answer:

D. \frac{79}{6}

Step-by-step explanation:

\bigg(  \frac{7}{2} -  \frac{1}{3}  \bigg).( - 2)^{2}  +  \frac{1}{2}  \\  \\  =   \bigg(  \frac{7 \times 3 - 1 \times 2}{2 \times 3}   \bigg).4  +  \frac{1}{2}  \\  \\  = \bigg(  \frac{21 - 2}{6}   \bigg).4  +  \frac{1}{2}  \\  \\  =  \frac{19}{6}    \times 4  +  \frac{1}{2}  \\  \\  = \frac{19}{3}    \times 2  +  \frac{1}{2}  \\  \\  = \frac{38}{3}   +  \frac{1}{2}  \\  \\  = \frac{38 \times 2 + 1 \times 3}{3 \times 2}   \\  \\  = \frac{76 + 3}{6}   \\  \\  = \frac{79}{6}

PLEASE HELP ASAP 9TH GRADE MATH AND I NEED HELP, 15 POINTS AND BRAINLIST HELPPPP
Sunny_sXe [5.5K]

Answer:

x = 40°

Step-by-step explanation:

Given that ∠SRT ≅ ∠STR

Then ∠STR = 20

∠STR  and ∠STU are what you call supplementary angles. This means that the sum of their measurements is equal to 180° because they form a straight line.

So if:

∠STR + ∠STU = 180°

m∠STU = 4x

m∠STR = 20

Then:

4x + 20° = 180°

Now we solve for x:

4x + 20 = 180\\\\Subtract\;20\;from\;both\;sides\;of\;the\;equation\\\\4x + 20 - 20 = 180 - 20\\4x = 160\\\\Divide\;both\;sides\;of\;the\;equation\;by\;4\\\\\dfrac{4x}{4}=\dfrac{160}{4}\\\\x = 40

x = 40°
