Harold will have to attend 5 weeks.
There is nothing to compare since both of the decimals are equal. The zero at the end doesn't mean anything.
Hope This Helps You!
Good Luck Studying :)
(3,2);y=3x-2
The equation is in slope-intercept form...
y=mx+b
m is the slope.
b is the y-intercept, the value of y when x=0.
Slope is 3.
Any line parallel to this has the same slope.
Point-slope formula...
y-y1=m(x-x1)
y-2=3(x-3)
y-2=3x-9
Let's add 2 to both sides...
y-2+2=3x-9+2
y=3x-7
Let's check our work...
(3,2)
2=[(3)(3)]-7
2=9-7
2=2
Answer:
C.
Step-by-step explanation:
red: 3/8 sheet per toy
20 × 3/8 = 60/8 = 56/8 + 4/8 = 7 1/2
yellow: 5/8 sheet per toy
20 × 5/8 = 100/8 = 50/4 = 25/2 = 12 1/2
Since he needs 7 1/2 and 12 1/2, he needs to get 8 and 13 becasue 7 and 12 are not enough.
Answer: C.
