6 bags of walnuts and 3 bags of peanuts
6 x 5 = 30
2 x 3 = 6
30 + 6 = $36
Answer:
Irene has 3 cupcakes right now. If she wants 8 cupcakes in total, how many more does she need to buy?
x = 5
Step-by-step explanation:
The problem breaks down to 3+x=8 because:
- 8 is the total number of cupcakes
- The total cupcakes is 3 and a number she will buy
- "x" is the number of cupcakes she will buy
Solve the equation:
We want to keep 'x' on the left side, moving everything to the right side (this is called isolating 'x'). Do the reverse operation to the entire equation for numbers you want to move.
3 + x = 8 Move the '3' to the right. The opposite of positive 3 is - 3
3 - 3 + x = 8 - 3 Subtract 3 from both sides. 3-3=0, it cancels out
x = 8 - 3 'x' is isolated. Solve right side
x = 5 Final answer
Therefore Irene will buy 5 cupcakes to get 8 in total.
Answer:
$6030.23
Step-by-step explanation:
The future value formula is useful for this.
FV = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years. Filling in the given values, we can do the arithmetic to find the amount.
FV = $4700·(1 + 0.025/4)^(4·10) ≈ $6030.23
The amount in the account will be $6030.23.
you don't list the options but it should look something like this:
68=2L+2(9)
Answer:
We ignore decimal point at first and multiply two variables.
Final is count all decimal points then add it.
Step-by-step explanation:
I. Multiply 104.3 with 10 and ignore the decimal points.
= 1043 * 10
= 10430
II. Count all decimal points from two variables,
in this case 104.3 is 1 decimal and 10 is 0 decimal so total decimal is 1 point
= 1043.0 or 1,043
Back to the question, why 104.3 * 0.10 is 10.43
stepI => 1043 * 1 = 1043 {when 0.10 is the same as 0.1} [decimal 1 + 1 = 2]
stepII => 10.43
Hope that help :)
