Answer: -30r + 15
Step-by-step explanation:
first, we multiply the parenthesis by 20.
-20 x 1.5r + 20 x 0.75
then, we multiply/calculate.
-30r + 15
27+6(2*2-1)4*2-5
2*2=4
27+6(4-1)4*2-5
4-1=3
27+6(3)4*2-5
6*3=18
27+(18)4*2-5
18*4=72
27+(72)*2-5
72*2=144
27+(144)-5
27+144+171
171-5=166
So the answer is 166.
Answer:
-1/-6
Step-by-step explanation:
1/6 is equivalent to-1/-6
6 5/6 - 5 1/12
6 5/6 x 2
6 10/12 - 5 1/12
6-5=1
10-1= 9
( You don't subtract the 12s in subtraction)
1 9/12
Simplified
1 9/12 both divided by 3
1 3/4
Final answer 1 9/12
Simplified answer 1 3/4
Answer:
1/3 is the y intercept
Step-by-step explanation:
f(x) = -2/9x + 1/3
This is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-2/9 is the slope and 1/3 is the y intercept
