Let's solve 'em all!

Original Equation: 
25 = 2x + 3
-3           -3
22 = 2x
/2    /2
11 = x (So now we are looking for an equation that has the solution: 11) 

A. 
28 = 2x
/2     /2
14 = x

B
22 = 2x
/2    /2
11 = x

C
50 = x + 3
-3         -3
47 = x 

D
25/2 = x + 3
12.5 = x + 3
-3           -3
9.5 = x


Thus, the answer is B since both 25 = 2x + 3 and 22 = 2x both are equivalent to 11.

Katie buys a large pizza for $14.99 and bottles of soda for $1.50 each. If the total cost was $23.99, how many bottles of soda (
Nady [450]

The number of soda bottles Katie bought is 6

The given parameters are:

  • Large Pizza = $14.99
  • Soda = $1.50 per bottle
  • Total cost = $23.99

Assume the number of soda bottle is x.

So, we have:

Total = Pizza + Soda \times x

This gives

23.99 = 14.99 + 1.50\times x

Subtract 14.99 from both sides of the equations

9 = 1.50\times x

Divide both sides of the equations by 1.5

6=x

Rewrite the equation as

x = 6

Hence, the number of bottles is 6

Sarah had invested $800 in a savings account that paid 4.2% interest compounded annually. How much money was in the account afte
schepotkina [342]

Answer:  $943.11

<u>Step-by-step explanation:</u>

Compound Interest formula is:   A=P(1+r)^t     where

  • A is the Accrued amount (total earned)
  • P is the Principal (amount initially invested)
  • r is the interest Rate (convert percent to a decimal)
  • t is the Time (number of years)

It is given that; P = 800    r = 4.2% (0.042)       t = 4

A = 800(1 + 0.042)⁴

A = 800(1.042)⁴

A = 943.106   →   A = 943.11 (rounded to the nearest penny)

Sarah invested $800 for four years at an interest rate of 4.2% and accrued $943.11

Find the center of the circle whose equation is (x - 8) 2 + (y + 2) 2 = 64.
SashulF [63]

If given the equation, you need to take the number beside the x and y and change their signs to get your point:

x - 8 (Take the -8 and make it +8)

y + 2 (Take the +2 and make it -2)

Your point is (8, -2)
