Answer:

25.5   and   37.5

Step-by-step explanation:

x+y=63

x-y = 12    then   x = 12 + y      sub this into the first equation

(12+y)    + y = 63

12 + 2y = 63

2y = 51

y = 25.5     then x = 37.5

What is the solution to the equation below? √x - 4 = -2 O A. X=& O B. X=4 X = 4 C. x = 6 D. X = 2
saul85 [17]

Answer:

x = 4

Explanation:

Given the expression;

\sqrt[]{x}-4\text{ = -2}

Add 4 to both sides

\begin{gathered} \sqrt[]{x}-4+4\text{ = -2+4} \\ \sqrt[]{x}=\text{ 2} \end{gathered}

Square both sides

\begin{gathered} (\sqrt[]{x})^2=2^2 \\ x\text{ = 4} \end{gathered}

Hence the value of x is 4

Point b is the midpoint of ac-. if ab= 4x+2 and ac=10x-6, find the length of ac
Natasha2012 [34]

let's bear in mind that B is the midpoint and thus it cuts a segment into two equal halves.

\bf \underset{\leftarrow \qquad \textit{\large 10x-6}\qquad \to }{\boxed{A}\stackrel{4x+2}{\rule[0.35em]{10em}{0.25pt}} B\stackrel{\underline{4x+2}}{\rule[0.35em]{10em}{0.25pt}\boxed{C}}} \\\\\\ AC=AB+BC\implies 10x-6=(4x+2)+(4x+2)\implies 10x-6=8x+4 \\\\\\ 2x-6=4\implies 2x=10\implies x=\cfrac{10}{2}\implies x= 5 \\\\[-0.35em] ~\dotfill\\\\ AC=(4x+2)+(4x+2)\implies AC=[4(5)+2]+[4(5)+2] \\\\\\ AC=22+22\implies AC=44

Brainliest to the correct answer, but answer ASAP
klemol [59]

the answer is 153.86 ft squared

= the formula for the area of a circle is A=πr2

= area = pi x radius squared

= the radius is 7 feet, square that to get 49

= multiply 49 by pi to get the area: 153.86 square feet

153.86 ft squared
