Answer:
Step-by-step explanation:
As with any "solve for ..." problem, you undo what is done to the variable of interest. Here, what is done is ...
- A is added
- the sum is multiplied by Y
You "undo" these operations in reverse order (from the bottom of the list up). To undo multiplication, you multiply by the reciprocal:
To undo the addition of A, add the opposite of A:
48 ÷ 0.08 = 600
check 600 × 0.08= 48
Let's use our largest amount (quarter) to see how many can fit evenly into 1.74.
- 1.74/0.25 = 6.96
- The most quarters that can fit into $1.74 is 6.
---Multiply $0.25 by 6 = $1.50
---Subtract $1.50 from $1.74 = $0.24
---We need to use the rest of the coins to fill up $0.24.
Now let's use our second largest amount (dime) to see how many can fit evenly into 0.24.
- 0.24/0.10 = 2.4
- The most dimes that can fit into $0.24 is 2.
---Multiply $0.10 by 2 = $0.20
---Subtract $0.20 from $0.24 = $0.04
No nickels can fit into $0.04, because they are worth $0.05.
We can use our least amount (pennies) to fill in the $0.04 remaining.
Your answer is 6 quarters, 2 dimes, and 4 pennies.
Answer:
a. Slope = 2; y-intercept = 2
b. Slope = 2; y-intercept = 3
c. Slope = 2; y-intercept = -1
d. Slope = -2; y-intercept = 5
e. Slope = -3; y-intercept = -5
d. Slope = -2; y-intercept = 1

Answer:
c. x = 1/a
Step-by-step explanation:
4ax + 5ax = 3ax + 6
9ax = 3ax + 6 (addition property of equality)
6ax = 6 (subtraction property of equality)
6ax/6 = 6/6 (division property of equality)
ax/a = 1/a (simplify)
x = 1/a
