Answer:
I got you!! If the speed limit is 60 mph, and shes driving 15 mph over the limit, its 75. 60 + 15=75!
Step-by-step explanation:
15 12 ÷ 15 12
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 15
15 12 ÷ 15
15 12 ÷ 15
=
1 12
1 12
=
1 12
12
= 1 12 per 12
Answer:
option B
Step-by-step explanation:
the slope is -2, so the equation must have -2x in it.
This narrows it down to option C and B
the intercept is at -5, not +5 so the correct answer is y = -2x - 5
Answer:
We applied distributive, associative and commutative properties to solve the calculus.
Step-by-step explanation:
3c+5(2+c)=<u>3c+5(2)</u>+5c (distributive property)
=3c+<u>5c+5(2) </u> (commutative property)
=<u>(3c+5c)</u>+5(2) (associative property)
=<u>(3+5)c</u>+5(2) (distributive property) by the shape of common factor extraction).
=8c+10 <u>3+5</u> is a simple add and <u>5.2</u> is a simple multiplication)
x+y-z+w = 10--------(1)
x+3y-4z+5w=26------(2)
x+4y-7z+7w = 37-------(3)
x+2y-3z+6w = 22--------(4)
Subtract equation (1) from (2)
x+3y-4z+5w - (x+y-z+w) = 26 - 10
2y + -3z - 4w = 16-----------------------------(5)
Subtract equation (1) from (3)
