Answer:
143
Step-by-step explanation:
divide 91 by seven. this will tell you how many oil changes happened in one day . ( answered 13) once you know that just times your answer by 11
F(x)=3x^2-5 when x=-11
f(-11)=3(-11)^2-5
f(-11)=-33^2-5
f(-11)=1089-5
f(-11)= 1084
Hope this could help!
Answer:x=-8
Step-by-step explanation:subtract 21 from both sides then simplify 31-21 to -8
So when you subtract by a negative number, it is the same thing as adding the two numbers.
First find a the LCD, or the least common denominator.
LCM(7,6) = 7•6 = 42
Then make the fractions have 42 as a denominator.
7 5/6 • 7/7 = 7 35/42
4 1/7 • 6/6 = 4 6/42
Finally, add the two mixed numbers
7 35/42
+4 6/42
11 41/42
So 11 41/42 is your answer
1. x+y+1 (x, y, and 1 are all terms)
2. 1+2
