Answer:
I won't solve it, because you asked me to.
Step-by-step explanation:
The first question we should ask ourselves is "what are we looking to solve?"
We are looking for some sort of value that satisfies that equation. We'll call it x
Reading from left to right:
The sum of twice a number and 13 is 75
+ 2 x 13 = 75
2x + 13 = 75
2 3/4 hours is 165 minutes
1hr and 55 min is 115 minutes
So 2 3/4 hours is 50minutes longer than 1hr and 55 min.

Step-by-step explanation:
we have
Applying distributive property
If you would like to know what is the full cost if 75% is £60, you can calculate this using the following steps:
75% of x = £60
75% * x = £60
75/100 * x = 60 /*100/75
x = 60 * 100 / 75
x = £80
Result: The full cost is £80.
x^2 + 5x = -2
x^2 + 5x + 2 = 0
We need to use the quadratic formula.
In the formula, a = 1, b = 5 and c = 2.
See picture for quadratic formula. Plug in the value for a, b, and c into the formula and do the math.
