SOMEONE PLZZZZZZ HELP
1 answer:
Answer:
<u><em>x = 3</em></u>
<u><em>angle B = 70 degree</em></u>
<u><em>angle C = 50 degree</em></u>
Step-by-step explanation:
<em>angle B + angle C = angle CDA ( exterior angle property)</em>
(22x+4) + (15x +5) = 120
22x + 15x + 4 + 5 = 120
37x + 9 = 120
37x = 120- 9
37x = 111
x =
x = 3
angle B = 22x + 4
= 22(3) +4
= 66 +4
angle B = 70 degree
angle C = 15x+5
= 15( 3) + 5
= 45 + 5
angle C = 50 degree

Answer:
$654
Step-by-step explanation:
Let the amount of money Marlina's received for her salary be x.
We know that she spent 1/2 of her salary on rent and then $338 on her electric and water bill. So, after this, she will have:
Left of her salary.
Next, she spent one half of what was left. So, it will be one-half of the equation. Therefore, she will have spent:
Finally, she spent $56 for gas. So, we will subtract 56:
And we know that after all of the expenses, she will have $102 left. Therefore:
We want to know how much Marlina spent on rent. So, let's find her salary x first.
First, let's distribute the 1/2:
Combine like terms:
Evaluate:
Add 225 to both sides:
Multiply both sides by 4:
Therefore, Marlina received a total of $1308 for her salary.
We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:
And we're done!
