Answer:
Solution set = {25}
Step-by-step explanation:
=> 
Dividing both sides by -1
=> 
Taking square on both sides
=> x = 25
<em><u>Solution set = {25}</u></em>
What the qoutient sweetheart
Answer:
a)5 b)15
Step-by-step explanation:
5 times 11=55
15 times 3 is 45
add together is 100
5+15 is 20 questions
Answer:
The smaller board would be 2.75 feet and the longer one would be 10.25 feet.
Step-by-step explanation:
In order to find this, assume the shorter board is equal to x. Next, we would know that the longer board would be equal to x + 7.5. Using these two assumptions, we can add the lengths together, set equal to 13 and then solve for x.
x + (x + 7.5) = 13
2x + 7.5 = 13
2x = 5.5
x = 2.75
Now that we have the length of the shorter board, we can add 7.5 to it to get the larger one.
2.75 + 7.5 = 10.25
