Answer:
A. a = 10
B. m<FNT = 120°
C. m<KTU = 60°
Step-by-step explanation:
A. (7a + 50)° and (14a - 20)° are corresponding angles. Therefore:
(7a + 50)° = (14a - 20)°
Use this equation to find the value of a
7a + 50 = 14a - 20
Combine like terms
7a - 14a = - 50 - 20
-7a = -70
Divide both sides by -7
-7a/-7 = -70/-7
a = 10
B. m<FNT = (14a - 20)° (alternate interior angles are congruent)
Plug in the value of a
m<FNT = 14(10) - 20
m<FNT = 140 - 20
m<FNT = 120°
C. m<KTU + (14a - 20)° = 180° (linear pair)
Plug in the value of a
m<KTU + 14(10) - 20 = 180
m<KTU + 120 = 180
m<KTU + 120 - 120 = 180 - 120
m<KTU = 60°
Answer:
Yes
Step-by-step explanation:
You can set up your proportion as 
* 
you then multiply across to get 
. Since this number is less than 1, it's definitely less than 3.
The variable in equations are always the letters so the variable in this equation is y
Answer:
carlos's first error is in step 2
Step-by-step explanation:
he should have written 14(40) + 14(9) , rather than 14(40) + 9
also not sure what the second part of your question is, but hopefully this still helps.
Answer:
Groceries is 625 a month
Step-by-step explanation:
25 percent of 2500 is 625. To get this answer take the percent and go back 2 decimal places this will turn 25% into 0.25 then multiply 2500 by 0.25 and the answer is 625. This also is the same with the other values. 0.30 0.15 etc.
