Answer:
$84.80
Step-by-step explanation:
find the difference between accurate price and written price: 74 - 47 = 27
find written total (before Mrs. Taylor found mistake) by undoing the mean calculation: 82.55 x 12 = $990.60
the total expenses is $27 more than what they thought: 990.60 + 27 = 1017.60
divide accurate total by 12 to find mean: 1017.60 / 12 = $84.80
hope this helps :)
Step-by-step explanation:
12y-(-4-8y)
= 12y +4 + 8y. ['-' getting multiplied when brackets open]
= 12y + 8y +4. [ Adding the like terms ]
= <u>20 y + 4 (Ans)</u>
Answer:
1/4 is your answer
Step-by-step explanation:
Answer:
AC ≈ 10.3
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan48° = 
= 
= 
( multiply both sides by 9.3 )
9.3 × tan48° = AC , then
AC ≈ 10.3 ( to 3 sf )
Answer:
k < 3/7
Step-by-step explanation:
Step 1:Sinplify both sides of the inequality
10k <-4k+6
Step 2: Add 4k to both sides
10k + 4k < -4k + 6 + 4k
14k < 6
Step 3:Divide both sides by 14
14k/14 < 6/14
k <3/7
