Answer: The square root of 81/49 is the answer
Step-by-step explanation:
Plug it in.
A being the coefficient of the first term, B the coefficient of the second, and C the coefficient of the third. . .
e.g.: 4x^2 + 7x - 8
a = 4, b = 7, c = -8
For all of these you're trying to solve for the variable. The variable is usually a number or symbol.
11) -44+n=36
Step one would be to add 44 to both sides of the equation.
N=80
12) -36=p-91
Step one would be to add -91 to both sides of the equation.
P=55
13) X-225=671
Step one you be to add 225 to both sides of the equation. Although it may seem difficult because of the big numbers, it's the same technique.
14) 19=c-(-12)
Step one on this equation will be a little different. Because there are two negative signs (-), they turn into a plus sign. Remember, two negative signs make a positive sign.
19=c+12
Now you just subtract 12 from each side of the equation.
6=C
Answer:y=5
Step-by-step explanation:
16y-56=27y-126+15
16y-56=27y-111
16y=27y-55
-11y=-55
y=5
