Answer:
-x+5
Step-by-step explanation:
5-5x+4x
= 5+(-5x)+4x
combine like terms:
5+(-5x)+4x
(-5x+4x)+(5)
= -x+5

Answer:
140°
Step-by-step explanation:
Angles 1 and 3 are "corresponding" angles, so are congruent.
∠1 = ∠3
20x +60 = 30x +20
40 = 10x . . . . . . . . . . . . subtract 20x+20
4 = x . . . . . . . . . . . . . . divide by 10
∠1 = 20x +60 = 20(4) +60 = 80 +60
∠1 = 140°
Answer:
He can make 3 batches of soup.
Step-by-step explanation:
Starting with 10 pounds of tomatoes and taking out the number of pounds he sets aside for spaghetti sauce, 2.8, we have:
10-2.8 = 7.2 pounds left.
0.2 is read as "two tenths," so 7.2 = 7 2/10
We divide this remaining number of pounds by 2 2/5 for each batch of soup:
7 2/10 ÷ 2 2/5
Convert each to an improper fraction:
72/10 ÷ 12/5
Multiply by the reciprocal:
72/10 × 5/12 = 360/120 = 3
(40x/64y)/(5x/8y)
(40x/64y)(8y/5x)
320xy/(320xy)
1
So I got 10 bows he can make
7 1/2 = 15/2 = 7.5
3/4 = .75
1) 7.50-.75=6.75
2) 6.75-.75=6.00
3) 6.00-.75=5.25
4) 5.25-.75=4.50
5) 4.50-.75=3.75
6) 3.75-.75=3.00
7) 3.00-.75=2.25
8) 2.25-.75=1.50
9) 1.50-.75=.75
10) .75-.75=0
10 times total
