Multiplication is really just repeated addition.
Answers:
- 10 x 3 or 10(3)
- 4 x 7 or 4(7)
- 8 + 8
- 3 + 3 + 3 + 3 +3 + 3 + 3 + 3 + 3
- m + m + m + m + m + m
- 5d
N = first integer
n + 1 = second integer
n + 2 = third
n + 3 = fourth
the sum is 114 so:
n + (n + 1) + (n + 2) + (n + 3) = 114
solve:
4n + 6 = 114
4n = 108
n = 27
so 27 is your first.
27 + 1 is your second (remember n +1 n +2 and n +3)
so your first four integers are: 27 28 29 and 30
(I'll also help with one)
week one: x
week two: x + 5
week three: 2(x+5) or 2x + 10
week1 + 2 + 3 = 431
so its:
x + (x+5) + (2x + 10)
4x + 15 = 431
4x = 416
x = 104
its then:
week one: 104 sold
week two: 109 sold (x + 5)
<span>week three: 218 (2x + 10)

Answer:
The outer circle is 16 feet larger than the inner circle (68 - 52).
Step-by-step explanation:
Given that the inner circle circumference is 52 feet, and the distance between the inner and the outer circle is 8 feet, to determine by how many ft is the larger outer circle, the following calculation must be performed:
The radius of a circle is equal to half its diameter. Therefore, the radius of the inner circle is 26 feet. Thus, if the distance between the two circles is 8 feet, the radius of the outer circle is 34 feet (26 + 8). Therefore, the diameter of this circle is 68 feet (34 x 2).
This implies that the outer circle is 16 feet larger than the inner circle (68 - 52).
Answer: y = 360,000 times t + 4.3%
Step-by-step explanation:
Given:
Original price = 20
reduces selling price by 25% every month it's not sold.
First markdown month:
20 * (100%-25%) = 20 * 75% = 15
Second markdown month
15 * 75% = 11.25
Macy, employee gets a 50% discount off the current price.
11.25 * 50% = 5.625
11.25 - 5.625 = 5.625 or 5.63
The pre-tax price of the shirt for Macy will be $5.63
