Answer:
15, 8, 25 The teacher payed 0.40 per book.
Step-by-step explanation:
4/10 = 2/5 Simplify the 4/10 to find the unit rate.
15: 2/5 = 6/x Set up your proportion.
2x =30 Cross multiply
/2 /2 Divide both sides by 2 to isolate x
x =15
8: 2/5 = x/20 Set up proportion
40 =5x Cross multiply
/5 /5 Divide both sides by 5 to isolate x
8 =x
25: 2/5 = 10/x Set up proportion
2x =50 Cross multiply
/2 /2 Divide both sides by 2 to isolate x
x =25
Graph: y=mx+b To graph, you will need to use y=mx+b format
y= 2/5 x+2 2/5 is your unit rate. Your rate changes every 2 books bought. To graph, start at (0,2) and go up 2 and to the right 5, plot. Continue moving up 2 and to the right 5 to graph.
The teacher payed 0.40 per book because 2/5 simplifies to 0.40.
Answer:
68°
Step-by-step explanation:
Okay, so m<8 is on the same plane as m<7 because line <em>q </em>is intersecting line <em>t </em>and that's supposed to add up to 180° so:
180° - 112° = 68°
So, m<7 = 68°
hope this helps:)
Answer:
40 quarts.
Step-by-step explanation:
Let x =quarts of the 50% solution
so, according to the question
the typical mixture equivalent equation will be like this
so the answer will be 40 quarts of 50% solution should be added.
Answer:
3x-x+2=4
Step-by-step explanation:
$15 + .5($10), or $20 total.
Since the books normally cost $25 total normally, Joseph paid $20/$25%, or 80% of both books (saving 20%)
