Answer:
37766245
Step-by-step explanation:
The correct answer is d that is because if it is 1 onch per 15 miles then do 11x15 and you get 165 c and d are the only 2 close enough to be it but from there you can cancel c because its 11.3 which means it must be more than 165. and d is the only one that is greater then 165
Answer:
i think tis will help
Step-by-step explanation:
standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.
Answer:
x=8
Step-by-step explanation:
First we know that 14x +1 and 11x-21 are supplementary angles because they add to 180 degrees. That is the given. Now we need to make an equation.
(14x+1) + (11x-21) = 180
Simplify the equation
25x -20 =180
Addition property of equality
25x =200
Division property of equality
x =8
Answer:
Step-by-step explanation:
(x+30) + (x-23) + (2x-7) = 180 degrees
4x = 180
x = 45
m<1 = x+30 = 75 degrees
m<2 = x-23 = 22 degrees
