The sum of two numbers is 17 and their differences is 29. What are the two numbers?

Answers

x + y = 17
x - y = 29

x = 17 - y
x - y = 29

x = 17 - y
17 - y - y = 29

x = 17 - y
17 - 2y = 29

x = 17 - y
- 2y = 29 - 17

x = 17 - y
-2y = 12

x = 17 - y
y = -6

x = 17 - (-6)
y = -6

x = 17 + 6
y = -6

x = 23
y = -6

Answer:

x + y = 17

x - y = 29

x = 17 - y

x - y = 29

x = 17 - y

17 - y - y = 29

x = 17 - y

17 - 2y = 29

x = 17 - y

- 2y = 29 - 17

x = 17 - y

-2y = 12

x = 17 - y

y = -6

x = 17 - (-6)

y = -6

x = 17 + 6

y = -6

x = 23

y = -6

Answer:

$0.67

Step-by-step explanation:

Cost of Watch on both sites=$45

Watches for Less charges a shipping fee of 4% of the cost of the watch.

Therefore, total cost of the watch at Watches for Less

=$45+(4% of 45)=45+(0.04 X 45)

=45+1.8

=$46.8

Tick Tock charges 2.5% of the cost of the watch for shipping.

Therefore, total cost of the watch at Tick Tock

=$45+(2.5% of 45)=(45+0.025X45)

=45+1.13

=$46.13

Difference In Cost

Cost at Watches for Less-Cost at Tick Tock

=$46.8-46.13

=$0.67

The total cost of the watch will be $0.67 less if purchased from Tick Tock

What is multiplication?

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Given that a bike wheel is 26 inches in diameter. The diameter of the bike wheel will be calculated by multiplying the two numbers.

Diameter in milimeters = 26.0 x 25.4

Diameter in milimeters = 660.4 mm.

Therefore, the diameter of the bike wheel in millimeters will be 660.4.
