A) the equation accuretly models this scenario because Emanuel has a total of 48 cards. He bought some (X) and his aunt gave him 18. In order to find the number of cards he bought you set the number of cards he bought and the number of cards he got from his aunt equal to the number of cards he has.
B) 48= X + 18
Subtract 18 over
30=X
He bought 30 cards from the store.
48+ 30+18
Answer:3/4
Step-by-step explanation:
<h3>
Answer: Choice A) 0.29 dollars</h3>
Work Shown:
16 ounces = 4.69 dollars
16/16 ounces = 4.69/16 dollars .... divide both sides by 16
1 ounce = 0.293125 dollars
1 ounce = 0.29 dollars .... rounding to the nearest cent
Step-by-step explanation:
5(x - 3) = 3 + 5x + 3x
5x - 15 = 3 + 8x
5x - 8x = 3 + 15
-3x = 18
x = 18/-3
x = -6
Answer:
Step-by-step explanation:
Here's how you solve this problem:
1. Solve for the slope in between the two points using (y2-y1)/(x2-x1)
For this problem that would be: (5-11)/(4+2), so the slope would be -1
2. Put that slope in a slope-intercept form equation and solve for the y-intercept.
Slope-Intercept Form: y=mx+b
y=-x+b
To solve for the y-intercept, use one of the coordinate pairs and input x and y.
11=-(-2)+b
9=b
3. Put that y-intercept back in the equation: y=-x+9
