Step 1:
Work out how much 2 loaves of bread was
1.45 x 2 = 2.9
Step 2:
Work out how much 3 cans of soup cost
0.5 x 3 = 1.5
Step 3:
Add up all the prices
1.5 + 2.9 + 2.5 = 6.90
Step 4:
Add the total of the items with the change
6.90 + 3.10 = 10.00
Step 5:
Answer
Heather gave the clerk a $10 bill
For this case we have the following equation:
We apply distributive property on the left side of the equation:
We add similar terms taking into account that, equal signs are added and the same sign is placed:
we subtract 6x on both sides of the equation:
We add 18 to both sides of the equation:
We divide by 8 on both sides of the equation:
Finally, the order of the steps is:
ANswer:
Slope of a line passing through two given points
= (y2-y1)/(x2-x1)
For m=3, and substituting coordinates,
3=(1-y)/(4-1)
solve for y
1-y=3*3=9
y=1-9=-8
Answer: y=-8
1= 6.928203 recurring
2= 3
3= 6.2449979984
4= 17
