Answer:
87 points
Step-by-step explanation:
lets take "x" as the avg test scores of the past 6 tests
so
since their are 6 tests, we would represent the 6 tests as "6x"
to find average we need to add all numbers, and divide by the number of numbers
so since the final exam counts as two tests we need to add "99" twice
so
(6x+99+99)/8=90
multiply by "8" on bots sides and add 99 and 99 together
6x+198=720
subtract 198
6x=522
divide by 6
x=87
hope this helps

Answer:
Length = 65 m
Width = 23 m
Step-by-step explanation:
Width = w
Length = 3w - 4
Perimeter of rectangle = 176 m
2*(length + width) = 176
2*( 3w - 4 + w ) = 176
2* ( 4w - 4) = 176
2*4w - 2*4 = 176
8w - 8 = 176 { add 8 to both sides}
8w = 176 +8
8w = 184
8w/8 = 184/8
w = 23 m
Length = 3w - 4
= 3*23 - 4
= 69 - 4
Length = 65 m
Answer:
B
Step-by-step explanation:
Solution
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define the converse of a statement
The converse of a statement is formed by switching the hypothesis and the conclusion.
STEP 2: break down the given statements
Hypothesis: If M is the midpoint of line segment PQ,
Conclusion: line segment PM is congruent to line segment QM
STEP 3: Switch the two statements
Hence, the answer is given as:
If line segment PM is congruent to line segment QM, then M is the midpoint of line segment PQ,
