Answer:

y = 4

Step-by-step explanation:

Move all terms containing y to the left, all other terms to the right. Add '-2y' to each side of the equation.

-5 + 3y + -2y = -1 + 2y + -2y

Combine like terms: 3y + -2y = 1y

-5 + 1y = -1 + 2y + -2y

Combine like terms: 2y + -2y = 0

-5 + 1y = -1 + 0

-5 + 1y = -1

Add '5' to each side of the equation.

-5 + 5 + 1y = -1 + 5

Combine like terms: -5 + 5 = 0

0 + 1y = -1 + 5

1y = -1 + 5

Combine like terms: -1 + 5 = 4

1y = 4

Divide each side by '1'.

y = 4

Simplifying

y = 4

The sum of the measures of two adjacent angles is 72 degrees. The ratio of the smaller angle to the

Goryan [66]

Answer:

The larger angle is 54°

Step-by-step explanation:

Given

Let the angles be: θ and α where

θ > α

Sum = 72

α : θ = 1 : 3

Required

Determine the larger angle

First, we get the proportion of the larger angle (from the ratio)

The sum of the ratio is 1 + 3 = 4

So, the proportion of the larger angle is ¾.

Its value is then calculated as:.

θ = Proportion * Sum

θ = ¾ * 72°

θ = 3 * 18°

θ = 54°

Kate borrowed $400 from her friend. She will repay this amount plus 3 percent simple interest after one year. What is the total

tekilochka [14]

The answer is $412.

Let's first calculate simple interest. Simple interest (I) can be expressed as:
I = P * r * t
P - principal
r - rate
t - time period

It is given:
I = ?
P = $400
r = 3% = 0.03
t = 1 year

Therefore:
I = P * r * t = 400 * 0.03 * 1 = 12

The total amount Kate will repay is the principal amount (P) plus 3% simple interest (I):
P + I = 400 + 12 = $412
