Answer:
960 ways
Step-by-step explanation:
Multiplication Principle: if there are n ways to do one thing and m ways to do another, then there are m x n ways to do both.
That can expand to include three things (or more).
8 x 10 x 12 = 960
Answer:
t = 200
Step-by-step explanation:
150 = 3/4t
3/4t = 150
t is being multiplied by 3/4 which equals 150 so in order to solve for t, you must divide 150 by 3/4
But first, convert 3/4 into a decimal
3/4 = 0.75
Second, divided 150 by 0.75 which equals t
t = 200
2x=5y
x-y=111
x=111+y
so 2x=5y is
2(111+y)=5y
222+2y=5y
2y-5y=-222
-3y=-222 (divide by -3 both sides of the equation)
y=-222/(-3)= 74
x=111+y = 111 +74 = 185
so the first number is 185 and the second is 74
Answer:
-43
Step-b-y-step explanation:
f(x)= -x^2+7x-13 so
f(-3)= - (-3)^2 + 7(-3) - 13
= -9 - 21 - 13
= -43.
