Answer:
A=27/4 B=2.25
Step-by-step explanation:
4 and 1/2 also equals 18/4.
18/4+1/2(18/4)=18/4+9/4
18+9=27
Answer is 27/4
B)=4.5/2=2.25
If you don’t know what a number is, you should substitute it for x and make an equation with the information you have been given. This gives:
(x + 8) x 2 = x - 11
Then, solve:
2x + 16 = x - 11
2x = x -27
x = -27
This can then be checked by using the number in the original text.
-27 + 8 = -19
-19 x 2 = -38
-38 is 11 less than -27.
Hope this helps :)
Answer:
False
Step-by-step explanation:
Vertical angles are a pair of opposite angles created by intersecting lines. The Vertical Angles Theorem states that if two angles are vertical, then they are congruent.
Answer: 5.875 miles run on Friday to reach her goal by Jen
Step-by-step explanation:
Since we have given that
Part of distance covered on Monday by Jen is given by

Part of distance covered on Tuesday by Jen is given by

Part of distance covered on Wednesday by Jen is given by
0
Part of distance covered on Thursday by Jen is given by

Total part of distance covered in these four days by Jen is given by

Remaining part of distance will be covered on Friday to reach her goal which is given by

Hence, 5.875 miles run on Friday to reach her goal by Jen.
Answer:
30degrees
Step-by-step explanation:
Given
Exterior angle m<CDE = 7x - 19 degrees
interior angles are
m<BCD = 2x - 1
m<DBC = x+10
Since the sum of the interior angles is equal to the exterior, hence;
2x - 1 + x+10 = 7x - 19
3x + 9 = 7x - 19
3x - 7x = -19 - 9
-4x = -28
x = 28/4
x = 7
Get m<CDE
m<CDE = 7x - 19
m<CDE = 7(7) - 19
m<CDE = 49 - 19
m<CDE = 30degrees
