3x + y = 18

Answers

Answer 1

Answer: basically eliminate
try eliminate y's
multiply second equaiton by 3
9x+3y=54

add to other equation
4x-3y=11
9x+3y=54 +
13x+0y=65

13x=65
divide 13 both sides
x=5

sub back
3x+y=18
3*5+y=18
15+y=18
minus 15
y=3

x=5
y=3
(5,3)

(NEED HELP)Your friend made $324 babysitting last year.This year she made 296% of what she made last year.How much more did your friend make this year?

Answers

The percentage is calculated by dividing the required value by the totalvalue and multiplying by 100.

Requiredpercentage value = a

total value = b

Percentage = a/b x 100

The moreamount made this year is $635.04

What is a percentage?

The percentage is calculated by dividing the required value by the totalvalue and multiplying by 100.

Example:

Requiredpercentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Your friend made $324 babysitting lastyear.

This year she made 296% of what she made lastyear.

This means,

The amount this year.

= 296/100 x 324

= $959.04

The difference in the amount.

= $959.04 - $324

= $635.04

The difference in the amount can also be calculated as,

= 296% - 100%

= 196% more this year.

So,

196% of $324

= 196/100 x 324

= $635.04

Thus,

The moreamount made this year is $635.04

Suppose you invest $4,600 into a savings account with a 8.25% annual interest ratethat compounds interest monthly. Use the TVM solver on your calculator to find the
future value of the account after ten years.

NEED ANSWER ASAP

Answers

Answer:

$10,467.06

Step-by-step explanation:

The computation of the future value is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

here

rate of interest = 8.25% ÷ 12 = 0.6875%

And, the number of years is = 12 × 10 = 120

So, the future value is

= $4,600 × (1 + 0.6875%)^120

= $4,600 × 2.275448086

= $10,467.06

Preston, can you please help!!!!! Or anyone else!!!!

Hello!

First you have to find the probability of a pulling a penny

To find this you put the amount of pennies over the amount of coins

There are 12 coins and 5 pennies

This is a 5/12 probability

Next you have to find the probability of then pulling out a quarter

Since you already took out a coin the total amount is now 11

The probability is 4/11

You multiply the two probabilities together to get the probability of them happening one after antoher

5/12 * 4/11 = 5/33

The answer is D)5/33

A rectangle has a perimeter of 80 feet. Its height is 5 feet shorter than 4 times its base. What are thedimensions (both base and height) of this rectangle?

Answers

Answer:

Let the height be x feet and the base be y feet

1st equation:

2(x+y)=80

x+y=40

2nd equation:

x=4y-5

x-4y=-5

Solution of the 1st and the 2nd equation:

x+y=40.1

x-4y=-5.-1

_________

x+y=40

-x+4y=5

_________

5y=45

y=9

x+y=40

x+9=40

x=40-9

x=31

. . The height is 31 feet and the base is 9 feet

Answer:

7 feet is the width, and 33 feet is the length.
