Answer:
A) 0 and 13
Step-by-step explanation:
64 - 37 = 27
27/2 = 13.5
13 teachers can teach 3 classes at max
3*3+4*4=x*x and 9+16=25 so x is 5 and then add other sides so 5+8+4+5
the answer is n=5
you just divide by 14 on both sides of the equation
Answer:
the answer is d.
Step-by-step explanation:
first, you want to use the formula,
new value - original value
<u>____________________</u>
original value * 100
you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.
84 - 79
<u>______</u>
79 * 100
now we solve it.
5
<u>__</u>
79 * 100
you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.
500
<u>____</u>
79 = approximately 6.3% increase (this is not a exact value, just rounded)
or
5
<u>__</u>
79 = approximately 0.063 (this is not a exact value, just rounded)
0.063 * 100 = 6.3% increase
Answer:
