Isabella buys poster boards.
Part 2 out of 2
Isabella spends $7.80 on paint brushes and paint. How many of each item does she buy? Complete the explanation how you found your answer.
By using compatible numbers, you find a total of items that had a total cost of $7.80. Then you used guess and check to find that she buys paint brushes and jars of paint.
Answer:
6 poster boards3 paint brushes, 5 jars of paintStep-by-step explanation:
Given poster boards are $0.75 each, you want to know the number purchased for $4.50. Given brushes are $0.95 and jars of paint are $0.99, you want to know the number of each purchased for $7.80.
1.The total price is the quantity times the price each:
4.50 = q × 0.75
q = 4.50/0.75 = 6
Isabella buys 6 poster boards.
2.Compatible numbers for the costs of brushes and paint are each 1. A compatible number for the total purchase is 8. This tells us Isabella bought 8 items for 7.80. This gives two equations in two unknowns:
0.95b +0.99p = 7.80
b + p = 8
Substituting for b, we have ...
0.95(8 -p) +0.99p = 7.80
`7.60 +0.04p = 7.80 . . . . . . simplify
0.04p = 0.20 . . . . . . . . . . . subtract 7.60
p = 0.20/0.04 = 5
b = 8 -5 = 3
Isabella buys 3 paint brushes and 5 jars of paint.
Check
0.95(3) +0.99(5) = 2.85 +4.95 = 7.80 . . . . answer checks OK

Additional comment
Note that we do not need to "guess and check" once we know the number of items purchased.
Or, we can "guess" without the business of compatible numbers by realizing the number of jars must be a multiple of 5 if the total purchase is a multiple of 5 cents. That leaves one possibility, since 10 jars is too many, and 0 jars is not enough.

Step-by-step explanation:
As a young girl, Tiana enjoyed watching her father make things in his woodworking shop. Now that she's grown up, Tiana builds wooden furniture for a living. Her most popular product is a cedar porch swing. There is a proportional relationship between the time (in days) Tiana spends making porch swings, x, and the number of swings she builds, y.
The equation that models this relationship is y=0.6x.
At this rate, how many swings can Tiana build in 20 days?
Answer: Tiana can build 12 swings in 20 days
Step-by-step explanation:
We know the equation:
y=0.6x
We can replace the variables.
y=0.6 x 20 (here, im using the x as a multiplication sign)
Now we calculate...
y=12
Answer: Tiana can build 12 swings in 20 days

Answer:
Do you want point-slope form, slope-intercept form, or standard form?
Question 1:
Point-slope form:
y-7=5(x-0)
Slope-intercept form:
y=5x+7
Standard form:
5x+y=7
Question 2:
Point-slope form:
y-7= -3(x+6)
Slope-intercept form:
y= -3x-2 or y= -3x+(-2)
Standard form:
3x+y=-11
Step-by-step explanation:
1. Points: (-2, -3) and (0, 7).
Find slope: m=7-(-3)/0-(-2)=7+3/0+2=10/2=5
Point-slope form:
y-7=5(x-0)
Slope-intercept form:
y=5x+7
Standard form:
-5x+y=7
2. Points: (-6, 7) and (0, -2)
m= -2-7/0-(-6)= -9/6= -3
Point-slope form:
y-7= -3(x+6)
Slope-intercept form:
y= -3x-2 or y= -3x+(-2)
Standard form:
3x+y=-11
Hope this helps! :D

ifying an Error Examine the work shown. Explain the error and find the correct result. 2(4 – 16) – (–30) 2(–12) – (–30) 24 – (–30) 54
Answer:
The error is in the middle: 2(-12) = -24 not 24.
Step-by-step explanation:
Evaluating the expression, the error made is the omission of negative in one of the digits. Hence, the correct result is 6
Given the expression :
2(4 - 16) - (-30)Evaluate the values in the bracket :
2(-12) - (-30)
Open the bracket
-24 + 30 = 6
The mistake made in the evaluation is the omission of negative in the digit 24.,
Therefore, the correct result is 6.
