2 + x = 19
what does x equal

Answers

Answer:

x = 17

Step-by-step explanation:

2 + x = 19

Subtract 2 on both sides to isolate the variable

2 - 2 + x = 19 - 2

x = 17

Check

We can check by distributing the "x" with 17 since thats what we got as the value.

2 + x = 19

2 + 17 = 19

19 = 19

CORRECT

What is the area of a circle with a radius of 13 feet?​

Answers

Answer:

530.93ft²

Step-by-step explanation:

together teammates Pedro and Ricky got 2666 base hits last season Pedro had 276 more hits than Ricky how many hits do each player have​

Answers

So first divide 2666 by 2 because there are two people and your trying to find out how many hits they both have. So after you divide should get 1333. Then add 276, and you should get 1609. So Pedro had 1609 hits and Ricky got 1057 hits. What you do to find Rickys is 2666-1609 and you get 1057.

Step-by-step explanation:

Using the Pythagorean Theorem, you would start with 90² + 90² = __²

90² = 8,100

8,100 + 8,100 = 16,200

√16,200 = 127.27922...

Rounded to the nearest tenth is: 127. 3 ft

I NEED HELP!!! You deposit $1,500 in an account earning 2.75% simple interest. How long will it take for the balance of the account to be $1,995?

Answers

12 years if interest is paid yearly
12 months if interest is paid monthly
Step-by-step explanation:
2.75% of $1500 is $41.25 interest per period
$1995-$1500 = $495 total interest
$495 ÷ $41.25 = 12 periods
Therefore it takes 12 interest periods to reach $1995, so the answer is 12 months or 12 years depending on how often interest is paid.

Find the solution of the system of equations -7x-3y=-20 3x+6y=-15

Answers

9514 1404 393

Answer:

  (5, -5)

Step-by-step explanation:

I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).

__

We can add the second equation to 2 times the first to eliminate the y-variable.

  2(-7x -3y) +(3x +6y) = 2(-20) +(-15)

  -11x = -55 . . . . . collect terms

  x = 5 . . . . . . . . . divide by -11

Substituting this value into the second equation, we have ...

  3(5) +6y = -15

  6y = -30 . . . . . . . . subtract 15

  y = -5 . . . . . . . . . . divide by 6

The solution is (x, y) = (5, -5).

Multiply (x – 3)(x + 5)

Explanation:

Lines of symmetry; A line that cuts a shape exactly in half

If you were to put a line of symmetry down and fold the shape in half on that line, both halves would match exactly.

If you were to put a line of symmetry down on this triangle both sides would not match, therefore there are no lines of symmetry.There are zero lines of symmetry, therefore your answer is [A] 0

It’s a quadrilateral parallelogram. Solve for x

Answers

4 sided shapes have internal angles that MUST add up to 360 degrees, so add all four angles to get 360 (opposite angles are equal) so:
8x + 19 + 8x + 19 + 21x - 13 + 21x - 13 = 360
Collect like terms so
58x + 12 = 360
58x = 348
x = 6

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.


At the end of the 4 years, how much interest in dollars and cents did the account earn? help asap

Answers

Answer:

$1105

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 6500 × 0.0425 × 4 = 1105

I = $ 1,105.00

The simple interest accumulated

on a principal of $ 6,500.00

at a rate of 4.25% per year

for 4 years is $ 1,105.00.

26034.03

subtract the original amount to find out how much was earned

26034.03-10000=16034.03

Step-by-step explanation:

8.3% of 10,000 is 830

1% of 10,000 is 100
