Answer:

x=15

Step-by-step explanation:

Hello there!

The shown angles are vertical angles

if you didn't know vertical angles are congruent

That being said we can create equation

5x + 40 = 115

now we solve for x

step 1 subtract 40 from each side

40 - 40 cancels out

115 - 45 = 75

now we have 75 = 5x

step 2 divide each side by 5

5x/5=x

75/5=15

we're left with x = 15

I think x is 15 because you set each side equal to each other to find x

Molly owes her brother $300.She works for $10 per hour as a checker at the local grocery store.Molly plans to repay her brother

gavmur [86]

Answer: The expression which represents the condition described is given as $4x=300$

Step-by-step explanation:

Since we have given that

Amount that Molly owes her brother = $300

Let the number of hours she worked as a checker be x

Cost of per hour = $10

Amount she get after doing work for x hours is given by

$10x$

Rate of tax are taken out = 80%

So, amount she left with is given by

$\frac{100-20}{100}\times 10x\\\\=\frac{80}{100}\times 10x\\\\=8x$

So, Molly plans to repay her brother half of what she earns is given by

$\frac{8x}{2}=4x$

According to question,

$4x=300\\\\x=\frac{300}{4}\\\\x=75\ hours$

So, the expression which represents the condition described is given as

$4x=300$

Luis has an account at GESA Credit Union. He had a balance of $500.00 starting January 15th. He made deposits of $100, $250, and

Oliga [24]

Answer: $531.51

Step-by-step explanation:

Initial balance of 500

If he made deposits into his account that means he added to his existing balance so his new balance would be the initial 500 plus all the deposits:

500 + 100 + 250 + 300 = 1150

so after the deposits he has a new balance of 1150. He then withdrew money which means he's subtracting from his balance so his new balance will be his current balance minus all the withdraws:

1150 - 400.32 - 100 - 55.55 - 62.62 = 531.51
