Answer:
The answer is 16
Step-by-step explanation:
8 divided by 2 (2+2)=16
I would love to use substitution (It is simplier that way I guess)
solve your system of equations.
x+2y=−1;x−y=5
Solve x+2y=−1 for x:
x+2y+−2y=−1+−2y(Add -2y to both sides)
x=−2y−1
Substitute (−2y−1) for x in x−y=5:
x−y=5
−2y−1−y=5
−3y−1=5(Simplify both sides of the equation)
−3y−1+1=5+1(Add 1 to both sides)
−3y=6
−3y/−3 = 6/−3(Divide both sides by -3)
y=−2
Substitute (−2) for y in x=−2y−1:
x=−2y−1
x=(−2)(−2)−1
x=3(Simplify both sides of the equation)
So the answer is (x = 3 and y = -2)
Answer:
X=6
Step-by-step explanation:
If B and C equal 8 and is larger than x than x is a smaller number. D and C is 4 but its smaller than x so x has to be bigger. Your left with 3 choices 5, 6, and 7. Measure it and find out how big x is and its between 6 or 7. If any means they do decimals it can also be 6.5 so x=6 or x=7 or x=6.5
Answer:
you need to use volume conversions for example like the metric system i had to use not to long ago use the common cooking conversion (its a conversion)
