Answer:
So we will be saving a total of $0.7 at new rate
Step-by-step explanation:
Given:
Original price =$ 0.69
New price = $ 2.75 per 5 switches
To find:
Saving = ?
Solution:
The original per price of the switch is given as = $ 0.69
Discounted price of 5 switches at $2.75
5 Switch price at original price = Original price * No of switches
= 0.69 * 5
= $ 3.45
Total saving at buying 5 switches = 3.45 - 2.75
=$0.7
So we will be saving a total of $0.7 at new rate
Displacement x would be in terms of length, while t would be in terms of time.
Therefore the equation would have units of:
length = (b)*time^2
b = length/(time^2)
Therefore, the units of the constant b should be in length per time^2 (for example, in m/s^2, such as in acceleration).

Step-by-step explanation:
Laid bricks in 2 hours = 42
laid bricks in a hour = 42/2
= 21
so rate is 21 bricks / hour
Answer:
12,8,12
Step-by-step explanation:
(x+3)+x+(2x-4)=31
4x-1=31
4x=31+1
4x=32
×=8(the second side)
x+3=8+3=12(the first side)
2x-4=16-4=12(the third side)
