x + 4y = 16 and 2x + 12y = 48 What is the value of x+y in the solution of the system?

Answers

Answer 1

Answer:

x = − 4y + 16

x = − 6y + 24

Step-by-step explanation:

Let's solve for x.

x + 4y = 16

Step 1: Add -4y to both sides.

x + 4y + − 4y = 16 + − 4y

x = − 4y + 16

Answer:

x = − 4y + 16

Let's solve for x.

2x + 12y = 48

Step 1: Add -12y to both sides.

2x + 12y + − 12y = 48 + − 12y/2x= − 12y + 48

Step 2: Divide both sides by 2.

2x/2 = − 12y + 48/2x = − 6y + 24

Answer: x = − 6y + 24

The cost of making a shirt is half of what the shirt normally sells for. Today, the shirt is in a 15 percent discount from its normal price. What is the current price of the shirt?

Answers

Answer:

.85 times the cost to make the shirt

Step-by-step explanation:

Let x represent cost to make the shirt.

Today, the shirt is in a 15 percent discount from its normal price.

Discount = 15/100 * x = 0.15x

Current cost = Original cost - discount

Current cost = x - 0.15x = 0.85x

The answer is;

.85 times the cost to make the shirt

Interest = $72.30
Principle = ?
Rate = 5%
Time = 3 years

Answers

Answer:

Step-by-step explanation:

Answer:

P = $ 482.00

Equation:

P = I / rt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

P = 72.3 / ( 0.05 × 3 ) = 482

P = $ 482.00

The principal required to

accumulate interest of $ 72.30

on a rate of 5% per year for 3 years is $ 482.00.

507 people use the public swimming pool , the daily price for children is 1.75 and the price for adults is 2.25 and the admission total was 971.75 how many children were at the public pool

Answers

Answer: 338 children

Step-by-step explanation:

Assume the children are represented by x and the adults are y.

Relevant equations will be:

x + y = 507 people

1.75x + 2.25y = 971.75

y = 507 - x

1.75x + 2.25 * ( 507 - x) = 971.75

1.75x + ‭1,140.75‬ - 2.25x = 971.75

1.75x - 2.25x = 971.75 - ‭1,140.75‬

-0.5x = -169

x = -169/-0.5

x = 338 children

Adults = 507 - 338

= 169 adults

I am not the best at math but I know that u can't change the bottom half of the fraction so it would just be four and then multiply the five and the three which would be fifteen. The answer would be 15/4ths. So you want to color in 15 boxes. Hopefully I could be of some kind of help to you!

Answer:

color in 15 boxes

15/32

Step-by-step explanation:

first off, the points are split so I'm only getting 12, just so that you know.

so 1/8x1/4 is 1/32, so each box is 1/32.

5/8x3/4=15/32 (multiply the top of the first with the top of the second and the bottom of the first with the bottom of the second)

so color in 15 boxes and the answer to the multiplication is 15/32

The angles of a triangle are in the ratio 1:2:3.What are the three angles of a triangle?

Answers

Answer:

30°, 60°, 90°

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 = 6 parts

divide the sum of the angles in a triangle. 180° by 6 to find the value of one part of the ratio.

180° ÷ 6 = 30° ← value of 1 part of the ratio , then

2 parts = 2 × 30° = 60°

3 parts = 3 × 30° = 90°

The 3 angles are 30°, 60° and 90°

Answer:

x = 27

Step-by-step explanation:

A circle adds up to 360 degrees. So we make this equation:

2x+21 + 5x+6 + 54 + 90 = 360

Combine like terms:

7x + 171 = 360

Subtract both sides by 171

7x = 189

Divide both sides by 7

x = 27

Answer:

Step-by-step explanation:

this has a bunch of "implied"  things that you're supposed to know.   one is that all the way around a circle is 360°   two is that if you know the angle on the interior.. that is also the arc length.. so knowing those things  we can say

360 = 54 + 2x + 21 + 5x + 6 + 90

put like terms together

360 = 171 + 7x

189 = 7x

27 = x
