Answer:
4.0541
Step-by-step explanation:
I don't know if this is correct but this is what I got.
You would take the error and divide it by the theoretical value and then multiply that by 100.
7.7 - 7.4 = 0.3
0.3 ÷ 7.4 = 0.04054054
0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%
Hope I helped in any way
Answer:
The equation for the given maths problem is $ 34 + $ 8x = $ 90
Step-by-step explanation:
According to question :
The Total amount spent on cloths = $ 90
The cost of a pair of jeans = $ 34
The cost of each t-shirt pair = $ 8
The amount spent on t-shirt = $ 90 - $ 34 = $ 56
Let the number of t-shirt pair = x
So, $ 34 + $ 8x = $ 90
Or, $ 8x = $ 90 - $ 34
∴ x = 
Hence The equation for the given maths problem is $ 34 + $ 8x = $ 90 Answer
Answer:
