5) Adam bought 5 DVDs that cost $12.95
each. How much did Adam spend
before taxes?
Answer:
$64.75
Step-by-step explanation:
You can add $12.95 five times:
$12.95 +12.95 +12.95 +12.95 +12.95 = spending
but it is probably easier to use multiplication:
5 × $12.95 = spending = $64.75
Adam spent $64.75.
Answer:
64.75
Step-by-step explanation:
So you have 5 DVDs bought and 12.95 for each.
12.95 x 5
12.95 + 12.95 = 25.90
25.90 + 12.95 = 38.85
38.85 + 12.95 = 51.80
51.80 + 12.95 = 64.75
So your answer is $64.75

Answer: 1.23×10¹⁶
Step-by-step explanation:
For this problem, we want to use order of operations to solve.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
Let's first solve the parenthesis.
[tex](9*\frac{999999999}{9+9+9+9+9+9+9+9+9} )^2[/tex] [add denominator]
[tex](9*\frac{999999999}{81} )^2[/tex] [cross multiply]
[tex](\frac{999999999}{9} )^2[/tex] [divide]
[tex](111111111)^2[/tex] [exponent]
1.23×10¹⁶
The ending result is way too large. Therefore, we use scientific notation and get 1.23×10¹⁶.

Step-by-step explanation:
A scientist records the number of deer observed in three areas of a forest. The table shows her observations. Area A 18 miles 162 deer. Area B 17 miles 153 deer. Area C 26 miles 234 deer. How many deer per square mile did the scientist observe in the forest?
9 deer per square mile
There are 9 deer per square mile because once you add all of the miles together it equals 61. Then you add all of the deer seen together equaling 549. You then divide 549 by 61 equaling 9.

18+(-4)=?
-5+(-18)=?
9+(-18)=?
-18+18=
please help me with the answers!!!
thanks
Answer:
Step-by-step explanation:
18+(-4)= 18 - 4 = 14
-5 + (-18) = - 5 - 18 = - 23
9 + (-18) = 9 - 18 = - 9
-18 + 18 = 0
Use the figure below to find the value of y and each angle shown.
5y - 16 + 3y + 20 = 180 degrees
Combine like terms on the left side
8y + 4 = 180
Subtract 4 from both sides.
8y = 176
Divide both sides by 8
y = 22
Plug 22 into y for each angle.
3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees
5y - 16 = 5(22) - 16 = 110 - 16 = 94
The angle opposite 5y - 16 also equals 94 because they are vertical angles.
The angle opposite of 3y + 20 also equals 86 because they are vertical angles

Answer:
Step-by-step explanation:
4(−12)=16
4 x -12 = 16
Himari's solution is incorect.
it should be like shown below.
4 - (−12 ) = 16
4 + 12 = 16
16 = 16
so it equates balance.

A) A plane takes off at 50 feet below sea level and climbs 1,542 feet. At what altitude is the plant currently flying?
B) How much higher does the plane have to climb to reach 3,400 feet?
Make sure you answer both parts of the question and label each part of the question.
Answer:
A) 1,492
B) 1,908
Step-by-step explanation:
A) The equation set up for this part is 1,542-50=1,492 We know that we're subtracting 50 from 1,542 because it say that the plane starts below sea level.
B) The equation set up for this part is 3,400-1,492=1,908 We know that we're subtracting the answer from part A from 3,400 because the plane will need to climb the difference in order to reach 3,400.
