Answer:
a)
[tex]a=23-z[/tex]
b)
First of all, I divided both sides by 2, simplified, and then subtracted z from both sides. Then, I got the final result for 'a'.
Step-by-step explanation:
a) Solving the equation
Given the expression
[tex]2\left(z+a\right)=46[/tex]
Divide both sides by 2
[tex]\frac{2\left(z+a\right)}{2}=\frac{46}{2}[/tex]
simplify
[tex]z+a=23[/tex]
subtract z from both sides
[tex]z+a-z=23-z[/tex]
[tex]a=23-z[/tex]
Thus, the value of a:
[tex]a=23-z[/tex]
b) Work Process
First of all, I divided both sides by 2, simplified, and then subtracted z from both sides. Then, I got the final result for 'a'.

Tyra's family is spending the afternoon in Millersville. They plan to see a movie and then explore the town. The movie will cost the family $36, and parking costs $4 per hour.
What cost is constant? That means which amount doesn't depend on how long they are there?
A. $36
B. $4
a video store charges
$10 for a rental card
plus $2.50 per video
game rented.
a. write an equation to
model the situation
b. What will be the total
cost if you decide to rent
20 video games?
c. How many video
games will you be able
to rent if you had $260?
Answer:
a. 10 + 2.50x
b. 60
c. 100
Step-by-step explanation:
a. 10 + 2.50x
b. 10 + 2.50(20)
= 10 + 50
= 60
c. 260 = 10 + 2.50x
250 = 2.50x
250/2.50 = x
x = 100
Here are the questions hehe
Answer:
89.10 / 4.95 is 18. so the first one is 18.
6 and 9, so we have to find the LCM. 6,12,18 and 9,18, so the first one to get a red and blue cap is the 18th bottle.
We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90 10,20,30,40,50,60,70,80,90.
The first one to get all three is the 90th bottle.
Hope this helps plz hit the crown :D

Answer:
1). x = 14
2). y = 2.4 cm
Step-by-step explanation:
In the diagram ΔNPQ ~ ΔNLM and NL = 3,
1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]
(3x + 18)° = 60°
3x = 60 - 18
x = 14
2). Since, both the triangles are similar, corresponding sides will be proportional.
[tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]
[tex]\frac{y}{3}=\frac{3.2}{4}[/tex]
y [tex]=\frac{3.2\times 3}{4}[/tex]
y = 2.4 cm
Fill in the blanks with two rational numbers (other than 1 and −1).
____ × (-1/2) × ____ = -20
Answer:
2 and 20
Step-by-step explanation:
First how can we get rid of the fraction?
We can multiply -1/2 by 2 to get -1
Next what number do we multiply to get from -1 to -20?
-1x = -20
divide both sides by -1
x = 20

Answer:
Option 4 (4, 2, 3)
Step-by-step explanation:
Coordinances for a three-dimensional coordinate system are (x, y, z).
The letter labeling each axis is always on the positive side.
Therefore, all of the coordinances must be positive.
If you look at the x,y plane you can identify that the point is two over on the y axis and four over on the x. You can use this same strategy on the z axis to get the coordinances (4, 2, 3).
Divide the polynomials.

Answer:
Step-by-step explanation:
This is a difference of squares.
√x^2 - √49 is the basic formula for factoring a difference of squares. The idea is that the middle term has been cancelled out.
√x^2 = x
√49 = 7
(x - 7)(x + 7) is the way this factors.
(x - 7)(x + 7)
===========
(x + 7)
The (x +7) in the numerator cancels with the (x + 7) in the denominator.
The answer is (x - 7)
====================================================
She might have wanted you to do it like this.
(x + 7) || x^2 + 0x - 49 || x - 7
x^2 + 7x ........... Subtract
==========
-7x - 49
-7x - 49 ...... Subtract.
=============
0
Or she might have seen you do this
x^2 - 49 x^2 49
======= = === - =====
x + 7 x 7

use the product property of exponents to justify that (9^1/2)^2=9
The rule states that
[tex](a^b)^c = a^{bc}[/tex]
So, in your case, you have
[tex](9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9[/tex]
. Find the equation of the straight line at a distance of 3 units from the origin such that the perpendicular from the origin to the line makes an angle a, given by the equation tan =5/12, with the positive direction of the axis of x?
Answer:
Plz Brain -list the answer It takes effort tnx dear
Step-by-step explanation:
From given condition
equation of line is given as,
x*cos(α)+y*sin(α)=p
& as tanα= 5/12 so from Pythagoras theorem
sinα= 5/13
cosα= 12/13
⇒12x+5y=39
⇒12x+5y−39=0p = 3, α = tan-1 (5/12) So, tan α = 5/12 sin α = 5/13 cos α = 12/13 The equation of the line in normal form is given by By using the formula, x cos α + y sin α = p Now, substitute the values, we get 12x/13 + 5y/13 = 3 12x + 5y = 39 ∴
use the function y=3/2x+3 to complete the table of values
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
Putting all the values of y=9, 6, 0, and -3 to complete the table
FOR y=9
putting y=9
switch sides
subtract 3 from both sides
Hence,
when y=9, x=4
FOR y=6
putting y=6
switch sides
subtract 3 from both sides
Hence,
when y=6, x=2
FOR y=0
putting y=0
switch sides
subtract 3 from both sides
Hence,
when y=0, x=-2
FOR y=-3
putting y=-3
switch sides
subtract 3 from both sides
Hence,
when y=-3, x=-4
Hence, the table becomes:
x y
9 4
6 2
0 -2

If cm= (K2-15) in cm = (10k +9) in how many inches is cc
Answer:
Step-by-step explanation:
cm= (K2-15) in cm = (10k +9) in
K2 - 15 = 10k + 9
K2 - 10k = 9 + 15
K2 - 10k = 24
2k - 10k = 24
-8k = 24
k = - 3

Jill drives at a rate of 50 miles per hour for 250 miles. If she plans to drive a total of 450 miles
during her trip, how many hours does she have left to drive at the same rate ?
Answer:
bsgdhv is the ghj is the most
Answer:
4 more hours.
Step-by-step explanation:
So, to calculate the remaining time Jill has to drive, we have to first find out how much distance Jill has left to cover:
[tex](450 - 250)[/tex] miles
= [tex]200[/tex] miles
So, at a rate of 50 miles per hour, Jill has to drive:
[tex]\frac{200}{50}[/tex] more hours
= [tex]4[/tex] more hours

HELP PLEASE John opens a savings account with a deposit of $25. After the initial deposit, he deposits $10 each week into his account. Which equation can be used to determine how much money, y, John has after x weeks?
A. y = 35x
B. y = 25x + 10
C. y = 10x + 25
D. y = 10x - 25
Answer:
C. y = 10x + 25
Step-by-step explanation:
If John put $10 each week but we don't know how many weeks that he deposits $10, use x as the amount of weeks. x10.
There was already $25 in his savings account so we don't have to put an x next to the $25.
Lortetta and her family are going on vacation. Their destination is 610 miles from their home. Loretta is going to share some of the driving with her dad. Her average speed while driving 55 mph and her dad's average speed while driving is 65 mph. The plan is for Loretta to drive for the first 4 hours of the trip and her dad to drive for the remainder of the trip. Determine th enumber of horus it will take her family to reach their desination.
Answer: 10 hours
Step-by-step explanation:
First and foremost, we should note that:
Speed = Distance / Time
Total destination = 610 miles
Loretta speed = 55 mph
Time to be used by Loretta = 4 hours
Loretta's distance = Speed × Time = 55 × 4 = 220 miles
The distance to be covered by her dad will then be:
= 610 - 220
= 390 miles
Her dad's average speed = 65 mph.
Time taken by her dad will be:
= 390 / 65
= 6 hours
The number of hours to be used by the family will then be:
Time taken by Loretta + Time taken by her dad
= 4 hours + 6 hours
= 10 hours

Find X (Its a circle question, PLEASE HELP)
Step-by-step explanation:
Since angles in the same segment are equal, Angle ABC (x) = Angle AOC.
Since Angles AOC and COD are supplementary, Angle AOC = 180° - 130° = 50°
Therefore x = 50°.
