X=18

Explanation:

The sum of the 3 angles in a triangle is 180∘

hence , the sum of the 3 angles given must equal 180

We can form an equation

2x + 3x + 5x = 180 ⇒10x=180⇒x=180/10
x=18

2(x) = 2(18)=36
3(18)=54
5(18)=90

Marie 2,480 windows Marie washed 4 times as many windows as Elizabeth Elizabeth washed the same number of windows each day over

vlada-n [284]

Answer:

Elizabeth washes 99 windows each day.

Step-by-step explanation:

Given:

Total number of windows (N) = 2480

Marie washes windows = 4 times Elizabeth washes.

Elizabeth washes same number of windows for 5 days.

Let the number of windows washed by Elizabeth each day = 'x'.

Therefore, over the 5 days, the windows washed by Elizabeth = $5x$

Now, as per question:

Marie washes windows = 4 times Elizabeth washes.

So, number of windows washed by Marie = $4(5x)=20x$

Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth

So,

$2480=20x+5x\\\\2480=25x\\\\x=\frac{2480}{25}\approx99$

Therefore, Elizabeth washes 99 windows each day.

Javier had $305in his bank account. His bank charges a fee of $7.50each month that a balance is below $500.

Mama L [17]

Answer:

Javier’s account has $282.5 at the end of the three months.

Step-by-step explanation:

final = initial - 7.5x

initial is the initial amount of money in the account, so 305. x is the number of months that have passed. Since Javier doesn't deposit any more money durning that time, the amount in the bank will always be less than 500 we don't have to consider anything else. We just sub initial with 305 and x ( the number of months) with 3 to get the answer. So,

final = 305 - 7.5 * 3 = 282.5
