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

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.

you invest 10000 that will earn 8.3% every year how much will you earn in 12 years.

Answers

Answer:

$16034.03

Step-by-step explanation:

I'm going to assume it's compound interest

10000(1+.083)^12

26034.03

subtract the original amount to find out how much was earned

26034.03-10000=16034.03

Answer:

$9960 would be earning in 12 years

Step-by-step explanation:

8.3% of 10,000 is 830

1% of 10,000 is 100

.3 would just be 30

.4 would be 40

etc etc

so 830 times 12(years) is $9960.00

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.

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

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.

y=5x-7
-3x-2y=-12
Find x

Answers

Answer:

11/6=x

Step-by-step explanation:

System of Linear Equations entered :

 [1]           y=5x-7

 [2]           -3x-3y=-12

Equations Simplified or Rearranged :

  [1]    y - 5x = -7

  [2]    -3y - 3x = -12

Graphic Representation of the Equations :

   -5x + y = -7        -3x - 3y = -12  

 

 

Solve by Substitution :

// Solve equation [1] for the variable  y  

 

 [1]    y = 5x - 7

// Plug this in for variable  y  in equation [2]

  [2]    -3•(5x-7) - 3x = -12

  [2]     - 18x = -33

// Solve equation [2] for the variable  x  

  [2]    18x = 33  

  [2]    x = 11/6  

// By now we know this much :

   y = 5x-7

   x = 11/6

// Use the  x  value to solve for  y  

   y = 5(11/6)-7 = 13/6  

Solution :

{y,x} = {13/6,11/6}
