Answer:
[tex]x=\frac{-10-z}{y}[/tex]
Step-by-step explanation:
1 Subtract z from both sides.
[tex]-10-z=xy[/tex]
2 Divide both sides by y
[tex]\frac{-10-z}{y} =x[/tex]
3 Switch sides.
[tex]x=\frac{-10-z}{y}[/tex]
2nd question
Answer: [tex]j=-\frac{4}{k-h}[/tex]
Step-by-step explanation:
1 Subtract h from both sides
[tex]-\frac{4}{j} =k-h[/tex]
2 Multiply both sides by j.
[tex]-4=(k-h)j[/tex]
3 Divide both sides by k−h.
[tex]-\frac{4}{k-h}=j[/tex]
4 Switch sides.
[tex]j=-\frac{4}{k-h}[/tex]
Answer:
[tex]\huge \boxed{x= \frac{-10-z}{y} } \\\\\\\\ \huge \boxed{j=\frac{4}{h-k} }[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
Solving for x:
[tex]-10=xy+z[/tex]
Subtracting z from both sides:
[tex]-10-z=xy[/tex]
Divding both sides by y:
[tex]\displaystyle \frac{-10-z}{y} =x[/tex]
Solving for j:
[tex]\displaystyle h-\frac{4}{j} =k[/tex]
Subtracting h from both sides:
[tex]\displaystyle - \frac{4}{j} =-h+k[/tex]
Multiplying both sides by j,
then dividing both sides by (-h + k):
[tex]\displaystyle - \frac{4}{-h+k} =j[/tex]
Simplifying the equation:
[tex]\displaystyle \frac{4}{-(-h+k)} =j[/tex]
[tex]\displaystyle \frac{4}{h-k} =j[/tex]
[tex]\rule[225]{225}{2}[/tex]

Sophie plans to repaint some classroom bookcases. All of the bookcases are the same size and each requires 4 over 5 gallons of paint. If she's going to paint 16 bookcases, how many gallons of paint does she need?
Answer:
12.8 gallons of paint
Step-by-step explanation:
Multiply 16 by [tex]\frac{4}{5}[/tex]
16(4/5) = 12.8
So, she will need 12.8 gallons of paint
Bob is buying the soccer team ice cream after their game today. 8 players want ice cream cookies and 5 players want ice cream cones. If ice cream cones cost $1.25 each and ice cream cookies cost $1.75 each, how much will Bob spend on ice cream for the team?
Answer:
Bob will spend on ice cream for the team $20.25
Step-by-step explanation:
Hello!!!
In this problem we are expected to solve for the total amount that Bob will spend to buy
8 players ice cream cookies and
5 players ice cream cones
let us calculate as follows
Cost of ice cream cookies for 8 players = 8*1.75= $14
Cost of ice cone for 5 players = 5*1.25= $6.25
Total cost = $14+ $6.25= $20.25

WILL GIVE BRAINLIEST TO THE FORST PERSON WHO ANSWERS THIS!! In the diagram below, lines AB and ED are parallel. Angle < BCD is a right angle and < CBF = 125 Find angle CDE.
Answer:
35°
Step-by-step explanation:
Produce BC in the direction of C which intersects DE at any point say P.
AB || ED... (given)
So, BP would be transversal.
[tex] \therefore m\angle DPB + m\angle FBP = 180\degree\\... (By\: interior \: \angle \: Postulate) \\
\therefore m\angle DPB + 125\degree = 180\degree\\
\therefore m\angle DPB = 180\degree - 125\degree \\
\huge \red {\boxed {\therefore m\angle DPB = 55\degree}} \\
m\angle DCP = 180\degree - 90\degree \\
m\angle DCP = 90\degree \\
x = 180\degree - (90\degree + 55\degree) \\
x = 180\degree - 145\degree \\
x = 35\degree [/tex]
The value of x or the angle CDE will be 35 degrees.
What is the opposite angle theorem?The theorem of vertical angles or angles that are vertically opposing According to the theorem, two opposing vertical angles that are created when two lines cross one other are always equal to one another.
Given that the angle CBF is 125 degrees. The value of the angle CDE will be calculated as below:-
Calculate angle ABC by using supplement angle property:-
∠ABC = 180 - 125 = 55
Draw a horizontal line PQ at point C.
Angle PCQ = 35
Angle CDE = 35
Therefore, the value of x or the angle CDE will be 35 degrees.

Which type of conic section is described by the equation 4x^2 = 10 +y^2? Due in 2 HOURS, will give BRAINLIEST! A. Ellipse B. Circle C. Parabola D. Hyperbola
Answer:
c
Step-by-step explanation:
Hyperbola is the conic section described by the equation 4x² = 10 +y²
What is Parabola?A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.
To identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,
Ax²+By²+Cx+Dy+E=0
The given equation is 4x² = 10 +y²
4x²-y²=10
Divide the whole equation by 10
4x²/10 - y²/10=1
2x²/5- y²/10=1
x²/(1/2)- y²/10=1
The given equation is in the form of hyperbola.
Hence, hyperbola is the conic section described by the equation 4x² = 10 +y²

∠A and ∠B are complementary angles. If the measure of ∠A is 42°, find the measure of ∠B.
Answer:
∠B = 48°Step-by-step explanation:
Since ∠A and ∠B are complementary angles their angles sum up to 90°.
In order to find ∠B add both ∠A and ∠B and equate them to 90° and solve for ∠B
That's
∠A + ∠B = 90
42 + ∠B = 90
∠B = 90 - 42
We have the final answer as
∠B = 48°Hope this helps you
Answer:
∠B = 48°
Step-by-step explanation:
A Complementary angles are total of 90°
If the measure of ∠A is 42°, find the measure of ∠B:
∠A + ∠B = 90°
42° + ∠B = 90°
∠B = 90° - 42°
∠B = 48°

Nicole charges a flat fee of $15 for babysitting plus $7 per hour a) write about equation to find the total payout. b) Evaluate an equation to find the total payout if Nicole babysits for 5 hours.
Answer:
a) t = 7x + 15
b) Nicole is paid $50 for 5 hours.
Step-by-step explanation:
flat fee = a price that will not change = $15
$7 per hour = a price of $7 for an unknown amount of hours (x) = 7x
Let "x" = amount of hours.
Let "t" = total cost.
Set the equation:
t = 7x + 15
Nicole babysits for 5 hours. Plug in 5 for x in the equation:
t = 7x + 15
t = 7(5) + 15
t = 35 + 15
t = 50
Nicole is paid $50 for 5 hours.

Answer:
x² - 1
Step-by-step explanation:
When x - 1 = 3 and x + 1 = 5 we know that x = 4 so (x - 1)(x + 1) = 4² - 1 when x = 4, 5² - 1 when x = 5 and so on. If you look carefully you will notice a pattern, the product is always x² - 1 so the answer to the blank is x² - 1.
