Each candy bar cost $5
work:
x = cost of candy bar
3+8(x)=43
-3. -3 < subtract 3 both sides
——————
8(x)= 40
—— —— 8 8
x=5
Answer:
Here's an example of long division:
Step-by-step explanation:
Let's just do 48 divided by 6. First you have to multiply the 6 (the number we're dividing with) until it reaches the closest to 48 (6 x 8 = 48). Now you subtract 48 from 48, and you get zero. So 48 divided by 6 would be 0.
Hope this answers your question!
Answer:
x = 1
y = -1
z = 2
Step-by-step explanation:
You have the following system of equations:
First, you can subtract euqation (3) to equation (1):
x + 2y - z = -3
<u>-x +y -z = - 4 </u>
0 3y -2z = -7 (4)
Next, you can multiply equation (3) by 2 and subtract it to equation (2):
2[ x -y + z = 4]
<u> -2x +y -z = -5</u>
0 -y + z= 3 (5)
You multiply equation (5) by 2 and sum (5) with (4):
2[ -y + z = 3]
<u> 3y -2z= -7</u>
y + 0 = -1
Then y = -1
Next, you replace y=-1 in (5) to obtain z:
-(-1) + z = 3
z = 2
Finally, you can replace z and y in the equation (3) to obtain x:
x - (-1) + (2) = 4
x = 1

Answer:
The product is 3/8
Step-by-step explanation:
When you multiply two fractions, first multiply the numbers on the top (numerators).
1 * 3 = 3
Then multiply the bottom numbers (denominators).
2 * 4 = 8
Now stick the first over the second.
3/8
