Answer:
he is correct he might have seen it's 3 times more than 18-29 which is 10% so he just multiplied 45 with 3
Answer:
I think if it takes me 8 hours then it will surely take him 8 hours
Answer:
formula: 2πrh
Step-by-step explanation:
2πrh= 2×π×4×5≈125.66371
7-(p+t) = 9(85-n) = 7(4+y)
Algebra is a kind of mathematics that includes symbols and the arithmetic operations across these symbols. These symbols do not have any fixed values and are called variables.
An algebra expression contain coefficient variable and a constant
We apply various methods to solve those question
An algebra expression is also called an equation
let the number be x
Seven less than the of p and t
= 7-(p+t)…….(1)
Nine times a number y subtracted from 85
= 9(85-n)…..(2)
Seven times the sum of four and y
= 7(4+y)……(3)
Combining equations (1), (2) and (3) according to the question :
7-(p+t) = 9(85-n) = 7(4+y)
