Answer:
25
Step-by-step explanation:
Elena's speed was 25mph
1/4 x 1/20
Answer:
Yes. Reduce 16/8 by dividing by 8. 16/8= 2, 8/8= 1. 16/8= 2. Reduce 6/3 by dividing by 3. 6/3= 2 , 3/3= 1. 6/3= 2.
The sum of the measures of the angles of a triangle is 180 degrees.
Angles STU and STR are supplementary angles.
Angles R and STR are congruent.
m<STU + m<STR = 180
8x + m<STR = 180
m<STR = 180 - 8x
m<R = m<STR = 180 - 8x
m<RST + m<R + m<STR = 180
7x - 54 + 180 - 8x + 180 - 8x = 180
-9x + 360 = 180
-9x = -126
x = 14
Answer: x=-3
Step-by-step explanation:
First you add 3x+5x cause they are both variables.They equal 8x.
Then you subtract 7x from both sides to get x+17=10
then you subtract 17 from both sides.
you will get x= -3
Hope that helps!
