A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21

Answer:
j=-2
Step-by-step explanation:
42j+18-19j=-28
Combine like terms
23j +18=-28
Subtract 18 from each side
23j +18-18 = -28 -18
23j =-46
Divide each side by 23
23j/23 = -46/23
j = -2
Answer:
14
Step-by-step explanation:
Divide 64 by 28.26. Then you get 2.2. Then multiply it by 64.
28 cans of soda into 2 groups in which the ratio is 3:4
3 x 4 = 12
4 x 4 = 16
12 + 16 = 28
you will put 12 cans in one group and 16 cans in another group
hope this helps
We have to draw the model for 42 divide 7 . In order to draw the model we use below steps.
- Draw 7 boxes to represent 7 groups.
- Assume 42 as the number which represents the total of these 7 groups.
- Put a question mark at the first box.
Attached is the model to represents 42 divide 7 .
In the question mark we should put 6. Hence, when we add 6 to 7 times that will be equal to 42.
