Answer:
x=10
Step-by-step explanation:
Using Pythagorean theorem,
(√13^2-12^2)×2
(√169-144)×2
(√25)×2
5×2=10
About 6.5 miles
this is because there will be about .54 miles in one minutes so then you multiply that by 12 and get about 6.5
hope that’s correct
Answer:

Step-by-step explanation:
We want to write an algebraic expression that represents the statement;
"eleven times the quotient of a number and 3 minus 15"
Let x be the number;
The quotient of a number and 3 is

eleven times the quotient of a number and 3 minus 15 is

This simplifies to:

Answer:
Expand the brackets, and simplify.
(4t - 8/5)-(3-4/3t) = (4t +4/3t) + ( -8/5 - 3) = 5 1/3t - 23/5 = 16/3t - 23/5
5(2t + 1) + (-7t + 28) = 10t + 5 - 7t + 28 = 3t + 33
(-9/2t + 3) + (7/4t + 33) = (-9/2t + 7/4t) + (3 + 33) = -11/4t + 36
3(3t - 4) - (2t + 10) = 9t - 12 - 2t - 10 = 7t - 22
