Answer:
D
Step-by-step explanation:
Start by subtracting 64 from both sides:

Factor this by taking roots. Divide both sides by 25 first:

We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are

Answer:
91
Step-by-step explanation:
Todd’s average score for six tests = 92.
The sum of two of her test = 188
First, we need to find the total score for the six test. This given below:
Average = sum of all test / number of test
sum of all the test = average x number of test
average score for six tests = 92.
Number of test = 6
Sum of all the Tests = 92 x 6 = 552
Sum of four test = sum of all the test — sum of two test
Sum of four test = 552 — 188 = 364
Now we can solve for the average of the other four test as shown below:
Average of four test = 364/4= 91
Answer:
In step 4, she forgot to move the decimal.
Step-by-step explanation:
Everything else is correct, but Hantet forget to move the decimal places 2 points to the right to make it 8% instead of 0.08%.
Always remember that percent is OUT of 100.
Hope this helps :)

It is 3,2 for sure Ik because in smart
<h3><u>15 tomatoes costs $10.</u></h3>
First, we need to convert this to a common factor.
The GCF of 6 and 15 is 3.
How do we go from 6 to 3?
Divide by 2.
6 = $4
Divide both by 2
3 = $2
How do we go from 3 to 15?
Multiply by 5
3 * 5 = 15
$2 * 5 = $10
