Answer:

  x = 7

Step-by-step explanation:

Vertical angles have the same measure, so ...

  m∠A = m∠B

  (5x -9)° = (8x -30)°

  21 = 3x . . . . . . . . . divide by °, add 30-5x

  7 = x . . . . . . . . . . divide by 3

The sum of 7 times a number and 5 is the same as the difference of the number and 7. Find the number.
kap26 [50]

Answer:

<em><u>pls mark me a </u></em><em><u>brainliest</u></em>

let x represent the number

7(x) + 5 = 7 - x

so we now group like terms

7x + x = 7 - 5

8x = 2

we now divide through by 8

\frac{8x}{8}  =  \frac{2}{8}

x =  \frac{1}{4}

the final answer for the number is 1/4

<em>Hope this will help</em>

Please please please help me i really need help<br><br> angle c = ___ degrees
OlgaM077 [116]

Answer:

angle c = <u>83</u> degrees

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral add up to 180 degrees.

According to the rule, <D and <B add up to 180° and same for <A and C.

This means that the sum of (x + 100) and (3x) equal 180.

Therefore (x + 100) + (3x) = 180 →

4x + 100 = 180

–100 –100

4x = 80

÷4 ÷4

x = 20.

Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.

Since <A + <C = 180.

97 + <C = 180 → 97 + <C = 180

–97 –97

<C = 180 – 97 = 83°

avanturin [10]
First, I would find the total area that Lisa needs to paint.
26x7=182 square feet

If a gallon of paint will cover 350 square feet, we will need to find out how many are needed to cover the fence.
g=gallons
350g=182
g=0.52 gallons of paint are needed
