Answer
-10
Step-by-step explanation:
-8w-7=9
add 7 to both sides
-8w=16
divide by negative 8 on both sides
w=-2
w-8=-10
On simplifying,
-8w - 7 = 9
-8w = 16
w = -2
then,
= w - 8
= -2 - 8
= -10.
Find (f^-1)'(7) without finding the inverse function where f(x) = 5 – 2x^3.
Step-by-step explanation:
the derivative of an inverse function is
1/f'(f^-1(x))
f'(x) = -6x²
f^-1(7) is solving the original function equation for x under the knowledge that y = 7
7 = 5 - 2x³
2 = -2x³
-1 = x³
=>
x = -1
f'(-1) = -6×(-1)² = -6×1 = -6
so,
(f^-1)'(7) = -1/6
At birthday Party girls ate 7 3/4
pizzas and the boys ate 2 1/2 pizzas. How many pizzas were eaten at my party?
Answer:
10 1/4
Step-by-step explanation:
2 1/2 = 5/2
5/2 (2/2)= 10/4
7 3/4 = 31/4
10/4+31/4=41/4
41/4 = 10 1/4

Answer:
A) 5; B) 32; C) 3; D) 14; E) 1/3
Step-by-step explanation:
Answer:
1. 5
2. 42
3. 3
4. 14
5. 0.3333
Step-by-step explanation:
Third Grade:
8 x 5 = 40
8 + 42 = 40
21 ÷ 7 = 3
21 - 14 = 7
---------------------------21 • x = 7
Which can be written as:
21x = 7
To solve the equation above, we need to remove the 21 on the left side to make the x alone. To do that, we divide both sides by 21.
21x/21 = 7/21
21x/21 is x and 7/21 is 0.3333 which means our equation will look like this:
x = 0.3333
Thus, the answer to "21 times what equals 7?" is 0.3333.

Joshua delivered 30 hives to the local fruit farm. If the farmer has paid to use 5% of the total number of Joshua’s hives, how many hives does Joshua have in all?
Answer:
600 hives
Step-by-step explanation:
If 30 is 5% of the total number of hives Joshua has, then 5%x20=100%
So, 30x20=100%
30x20=600

Find the standard deviation of the given data rounded to the nearest hundredth.3, 4, 5, 7, 10, 12, 15
Answer:
4.140393356
Step-by-step explanation:
Mean = (3+4+5+7+10+12+15) / 7 = 8
Count = 7 numbers
Sum of the numbers = 56
Each number minus the mean =
(3-8=-5)(4-8=-4)(5-8=-3)(7-8=-1)(10-8=2)(12-8=4)(15-8=7)
Now square of each of these numbers:
25+16+9+1+4+16+49 = 120
Variance = 120/7 = 17.14285714
Standard deviation = square root of the variance
Sqrt 17.14285714 = 4.140393356

The volume of a cylinder is 301.44 cubic inches. If the area of the base is 37.68 square
inches, what is the height of the cylinder?
Answer:
8 inches
Step-by-step explanation:
Height = Volume / Base Area = 301.44 / 37.68 = 8
What is the equation of this line?
y=34x−3
y=−3x−34
y=−3x−43
y=43x−3
Step-by-step explanation:
this line goes through the points (0, -3) and (4, 0).
so, the y-axis intercept is at y = -3.
therefore, the equation has to end with "- 3".
the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :
x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).
so, the slope is 3/4.
and so, the equation is
y = (3/4)x - 3
Joe has $180 in his bank account he wants to buy a new gaming system for $250 in two weeks his parents have offered to lend him money if he needs it he gets $20 a week for a allowance will he have enough money at the end of two weeks to make the purchase of his own if not how much will he have to borrow from his parents explain
Answer:
yes he will
Step-by-step explanation:
Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Here given that,
Joe has $[tex]180[/tex] in his bank account he wants to buy a new gaming system for $[tex]250[/tex] in two weeks his parents have offered to lend him money if he needs it he gets $[tex]20[/tex] a week for a allowance
So,
His account saving is $[tex]180[/tex].
He wants to purchase a game system which costs $[tex]250[/tex].
His parents giving $[tex]20[/tex] per week. So iin two weeks it is [tex]20(2)=40[/tex]$.
Then , the total savings he had [tex]180+40=220[/tex]$
So he needs [tex]30[/tex]$ more to purchas his game system
If his parents giving him $[tex]35[/tex] per week then in two weeks it would be [tex]35(2)=70[/tex]$.
Then his total savings are
[tex]180+70=250[/tex]$.
Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.

Distributive property, Inverse Operation, and Division property of Equality
Step-by-step explanation:
Because 8•x is 8x and 8x3 is 24 so then the equation would be 8x-24=-40 then you have to add 24 on both sides to the 8x by itself and also get -16 which you would divide 8 on both sides to get x= -2

Answer:
1, 4, 5, 6
Step-by-step explanation:
1 - Division is considered a fraction, subjected to fraction as division also. Since - 5/17 is basically considered -5/-17 (via 4), 1. is a choice.
4 - As explained, - 5/17 is -5/-17, so this is also a choice.
