two angles are supplementary one angle measures 75% more than twice the measure of the other what are the measurement of the two
valkas [14]
Let's call the angles x and y. We know that supplementary angles must add to 180 degrees, so x+y=180.

Furthermore, we know that x is 75% more than 2y. We can write "75% more than" numerically as 1.75, so x = 1.75(2y).

We can simplify the second equation by multiplying 1.75 and 2 together to get x = 3.5y.

Now we can solve the system of equations by substitution by plugging 3.5y in for x in x+y=180.

(3.5y) + y = 180

Combine like terms.

4.5y = 180

Divide by 4.5

y = 40

Plug y = 40 in and solve for x.

x + 40 = 180

x = 140

The answer is 40 and 140. Hope this helps :)

At the end of 6 weeks, he will have $80.

At the end of 7 weeks, he will have $90.

At the end of 8 weeks, he will have $100.

At the end of 9 weeks, he will have $110.

At the end of 10 weeks, he will have $120.

Translate the following sentences into a equation, then solve the equation.
Rainbow [258]

Answer:

Step-by-step explanation:

Let the two numbers be x and y

x = y - 5......(1)

2y = 3x.......(2)

Putting (1) into (2)

2y = 3(y - 5)

2y = 3y - 15

Collecting like terms

2y - 3y = -15

-y = -15

y = 15

Putting y = 15 in (1)

x = y - 5

x = 15 - 5

x = 60
