Answer:

X = 10

Step-by-step explanation:

<1 = 2x + 10

<2 = x + 20

<3 = 180 - 6x (linear angles = 180 degrees)

<1 + <2 + <3 = 180 degrees

2x + 10 + x + 20 + 180 - 6x = 180

-3x + 210 = 180

-3x = 180 - 210

He started with 53 cards

He has 31 now

If 31 is half of what he had, then we need to double it

31 x 2 = 62

D) -6x+2y=12

Answers

Answer:

The number of students at Yellowstone High School has been increasing by 4% each year. There are
currently 4,256 students. How many students will there be in 8 years?

Answers

Answer:

5,617.92

Step-by-step explanation:

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:

A = 4256(1 + (0.04 × 8)) = 5617.92

A = $5,617.92

The total amount accrued, principal plus interest, from simple interest on a principal of $4,256.00 at a rate of 4% per year for 8 years is $5,617.92.

P = $3600, I = $330, t = 1 year

Answers

Answer:R = 9.1667%/year

Step-by-step explanation:

Solving our equation

r = 330 / (3600 × 1) = 0.09166667

r = 0.09166667

converting r decimal to a percentage

R = 0.09166667 × 100 = 9.1667%/year

The interest rate required to

accumulate simple interest of $330.00

from a principal of $3,600.00

over 1 years is 9.1667% per year.

Bentley was playing with 3 old dog toys and 6 new dog toys. If Bentley has 18 old dog toys how many new dog toys does he have?

Answer: 36 new dog toys

Step-by-step explanation: With the given information, we can see that Bentley has a total of 18 old dog toys. IF Bentley is playing with a proportional relationship of toys, then all we have to do is multiply 6 by 6. Since 3 times 6 is 18, we have to do 6 times 6 which is 36.
