Answer: B
Negative a squared b and 5 a squared b
Step-by-step explanation:
Given that:
Negative a squared b + 6 a b minus 8 + 5 a squared b minus 6 a minus b. That is,
- a^2b + 6ab - 8 + 5a^b - 6a - b
Collecting the like term by rearranging the expression
5a^2b - a^2b + 6ab - 6a - b
The like terms in the expression above are
5a^2b - a^2b.
The correct option is B:
Negative a squared b and 5 a squared b or (-a^2b and 5a^b)
L+S=8, L=8-S
500L+200S=2200, using L from above in this equation gives you:
500(8-S)+200S=2200
4000-500S+200S=2200
4000-300S=2200
-300S=-1800
S=6, and since L=8-S:
L=2
So Rita bought 2 large packets and 6 small packets.
In order to keep the constant, the same and not vary there must be an indirect or inverse relationship to always maintain the value of k.
Thus both P and V are inversely related to each other.
Ratio: 30:18
If you were asking for the ratio-
Compare: 30 minutes is 12 more minutes than 18
If you were asking which one is grater-
(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y
Replace x and z with y in function (1)
780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330
Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520
