answer: she is right that y = 29, but step three should be addition property of equality.

work: let's see how she worked to isolate y. she started by subtracting 2y from both sides, so so far she is correct. after that, she added 84 to both sides, and again that is a correct step, but her proof is wrong, since you are adding and not subtracting 84, it's the addition property of equality. lastly, she divided 145 by  and correctly got 29. so yes, she is correct.

What if the value of x? show all work
alina1380 [7]
For this case we can make use of the Pythagorean theorem.
 We have then:
 (root (117)) ^ 2 = x ^ 2 + 6 ^ 2
 Clearing x we have:
 x ^ 2 = (root (117)) ^ 2 - 6 ^ 2
 Rewriting:
 x = root (117-36)
 x = root (81)
 x = 9
 Answer:
 
The value of x is given by:
 
x = 9 cm

Multiplication
Addition
Subtraction

First look at the Brackets
There are no indices in the brackets
There is no division in the brackets
There is a Multiplication in the brackets    7 x 3


For the answer

(9 - 7 x 3 + 4)²
Brackets
Multiplication   7 x 3 = 21
(9 - 21 + 4)²
Addition   -21 + 4 = -17
(9 - 17)² 
Subtraction    9 - 17 = -8
-8² 

Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64

Find the simple interest paid to the nearest cent for each principal, interest rate, and time. $570,2%, 4 years.
WARRIOR [948]
The answer is 45.6. You multiply the beginning amount to the interest rate to understand how much interest you get. Then multiply that by the amount of years the interest is gathered. 570 * .02 = 11.4 * 4 = $45.6 interest. Add this to 570 for the original amount of 615.6.
