So, firstly, in order for us to know how much is each baseball card pack, we divide 12 dollars by 4 and we get 3. Therefore, each baseball card pack costs $3. So for 21 dollars, he can purchase 7 baseball card packs. 21 divided by 3 is 7. Hope this answers your question. Have a great day!
1. 5x - 7 = 48
5x = 48 + 7 = 55
x = 55/5 = 11
2. 7n - 2 = 54
7n = 54 + 2 = 56
n = 56 / 7 = 8
3. -4y + 7 = -21
-4y = -21 - 7 = -28
y = -28 / -4 = 7
4. x/2 + 5 = 12
x/2 = 12 - 5 = 7
x = 7 * 2 = 14
5. x/3 - 7 = 13
x/3 = 13 + 7 = 20
x = 20 * 3 = 60
6. -7 - 2 = 33 <- did you type this wrong?
-7x - 2 = 33
-7x = 33 + 2
-7x = 35
x = 5
7. -3x - 8 = -41
-3x = -41 + 8 = -33
x = -33 / -3 = 11
8. 3n - 7 = 35
3n = 35 + 7 = 42
n = 42 / 3 = 14
9. 7y + 9 = -47
7y = -47 - 9 = -56
y = -56 / 7 = -8
10. -8x + 4 = 68
-8x = 68 - 4 = 64
x = 64 / -8 = -8
11. 4n - 7 = -43
4n = -43 + 7 = -36
n = -36 / 4 = -9
12. 5x - 7 = 108
5x = 108 + 7 = 115
x = 115 / 5 = 23
13. 8 - 5w = -37
-5w = -37 - 8 = -45
w = -45 / -5 = 9
14. 42 = 18 + 4n
4n = 42 - 18 = 24
n = 24 / 4 = 6
15. 70 - 6x = 40
-6x = 40 - 70 = -30
x = -30 / -6 = 5
Answer:
Slope: 3/2
X-intercept: 2/3y + 2
Y-intercept: 3/2x - 3
Step-by-step explanation:
For the slope you have to put it in y intercept form to become y = 3/2x - 3
The slope is 3/2. x intercept is the opposite. x = 2/3y - 2
Answer:
4
Step-by-step explanation:
Answer:
2x+10
Step-by-step explanation:
