85 = 10x+15
70 = 10x
x = 7
180-85 = 95 = z
Answer:
4
Step-by-step explanation:
Any point with the y of 5 could be the answer
Answer:
There are 91 dimes in the jar.
Step-by-step explanation:
5n+10d= 1455
n+d = 200
n=200-d
5(200-d) + 10d=1455
1000-5d+10d=1455
1000+5d=1455
5d=455
d=91
91 dimes
Answer:
no solution
Step-by-step explanation:
-9x +5 < 17 AND 13x + 25 < -1
Solve each part separately and then put back together
-9x +5 < 17
Subtract 5 from each side
-9x+5-5< 17-5
-9x < 12
Divide each side by -9 remembering to flip the inequality
-9x/-9>12/-9
x > -4/3
and
13x + 25 < -1
subtract 25 from each side
13x +25-25 < -1-25
13x <-26
Divide by 13
13x/13 < -26/13
x <-2
There is no overlap so there is no solution
