Answer: an triangle's angles will always add up to 180 so: 54+82=136 180-136=56 x=56

We also know that vertical angles are the same. (angles across from each other) and that the sum of these 4 angles will be 360. using this, we get 56+56=112 and then we do 360-112=248 248/2=124 So y=124.

I hope this helps.

y = 180° - x

x = 180° - (82° + 54°) } => y = 82° + 54° = 136°

To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of

babymother [125]

Answer:

The value of y is $y=\frac{42}{17}$

Step-by-step explanation:

we have

$4x+3y=6$ -----> equation A

$18x+5y=6$ -----> equation B

To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides

I choice

Multiply the equation A by -18/4 both sides

$(-18/4)[4x+3y]=6*(-18/4)$

$-18x-13.5y=-27$ ------> equation C

Adds equation B and equation C

$18x+5y=6\\-18x-13.5y=-27\\-------\\5y-13.5y=6-27\\-8.5y=-21\\\\ y=\frac{42}{17}$

Larry has taken out a loan for college. He started paying off the loan with a first payment of $150. Each month he pays, he want

miss Akunina [59]

Answer:

Divergent

Step-by-step explanation:

We can make use of the exponent function to solve this question. The function would be like:

$an = a_1 (r) ^ {n - 1}$

where $a_1$ is the first payment ,

$r$ = ratio of increase ; and

$n$ = the number of payments.

So it can be written as:

$f ( n ) = 150 * 1.3 ^ {( n - 1 )}$

The series will keep increasing since the ratio of the function is 1.3 which was > 1 so. Therefore, the series is divergent.
