Answer:
10 quarters
40 dimes
Step-by-step explanation:
q + d = 40
25q + 10d = 625
25 > 10
q < d
25(10) = 250
10(40) = 400
$2.50 + $4.00 = $6.00
Answer:
Look below
Step-by-step explanation:
lets have -29 be y2 and -5 be x2
21 - (-)29
5 - (-)5
Subtracting a negative is just adding it so
21 + 29 50
5 + 5 10
50/10
this simplified, is 5/1 or 5
y=5x+b
now we need to find b, so we substitute y and y
x = 5
y = 21
21=5*5=b
5*5 is 25
now we need to get to 21
25 -4 is 21
b = -4
y=5x-4
Answer:
mkana
Step-by-step explanation:
<span>-5(3t-5)+7t=8t-6
-15t + 25 + 7t = 8t - 6
-15t + 7t - 8t = -6 - 25
-16t = -31
16t = 31
t = 31/16 = 1.9375</span>

Step-by-step explanation:
1) Collect like terms.

2) Simplify.

So, therefor, the answer is -17y - 16z + 4.
