n is a number
"the sum of <span>a number and twelve" is (n+12)
"</span><span>Six times the sum of a number " is 6(n+12)
6(n+12)=40
6n+72=40
6n=40-72
6n= - 32
n=-32/6 = -16/3 or -5 1/3</span>
C, add the 5 in X and it still equals 12
Answer:
she is correct
Step-by-step explanation:
rational numbers are not whole numbers, and -3 is a whole number. For example, -1/3 is a rational number, but -3 is not.
Sorry if im wrong, im bad at math :(
gradient or slope=<u>y2 -y1</u>
x2 - x1
so for A, p is x1 and 3 is y1..
For B, 6 is x2 and p is y2
2= <u>p - 3</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>6 - p
2 ( 6 - p) = p - 3
12 - 2p = p - 3
-2p + p = -3 - 12
-p = - 15
p = 15
When dividing two terms with the same base, subtract the exponent in the denominator from the exponent in the numerator: Power of a Power: To raise a power to a power, multiply theexponents.
