Combine like terms: 4-4z+5z-2+2z then solve
Answer:
3z+2
Step-by-step explanation:
Answer:
2 + 3z
Step-by-step explanation:
4 - 4z + 5z - 2 + 2z
4 - 2 = 2
-4z + 5z + 2z = 3z
= 2 + 3z
We don't know what 'z' is, so that is the most that I can simplify it.
4 - 4z + 5z - 2 + 2z
= (4) + (-4z) + (5z) + (-2) + (2z)

You collect $20.92 for selling 4 video games and 2 cellphones on a website. Your friend collects $23.44 for selling 4 video games and 3 cellphones on the website. How much do you collect for each video game?
Answer: D
Step-by-step explanation:
x = video games
y = cellphone
Equation: (1) 4x + 2y = 20.92
(2) 4x + 3y = 23.44
_________________
y = 2.52
4x + 2y = 20.92
4x + 2(2.52) = 20.92
4x = 20.92 - [ 2(2.52) ]
4x = 15.88
x = 3.97
Amount collected for each video game is option D. $3.97.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the amount got for selling one video game and y be the amount got for selling cellphones.
You collect $20.92 for selling 4 video games and 2 cellphones on a website.
4x + 2y = 20.92
4x = 20.92 - 2y
Your friend collects $23.44 for selling 4 video games and 3 cellphones on the website.
4x + 3y = 23.44
4x = 23.44 - 3y
Equating both the equations,
20.92 - 2y = 23.44 - 3y
Simplifying,
y = 2.52
Substituting y = 2.52 in 4x + 2y = 20.92,
4x = 15.88
x = 3.97
Hence the amount for selling one video game is $3.97.

help lol............
Step-by-step explanation:
y=19°{ vertically opposite angle r equal}
y+z=90° {given in questions.}z=90-19z=71°
hope it helps.
stay safe healthy and happy.Answer and Step-by-step explanation:
1.
I see the Vertical Angles Theorem being used with the angle of 19 and angle y.
Vertical Angles Theorem states that angles that are vertical to each other are congruent to each other.
I see the Complementary Angles Theorem being used with the angle y and angle z.
Complementary Angles Theorem states that angles that are next to each other and are split by a line of a right angle will add up to 90 degrees.
2.
y = 19
y + z = 90
Substitute 19 for y.
19 + z = 90
Subtract 19 from both sides of the equation.
z = 71

Kristen wants to ask the managers of the fast food restaurants in a large city "How do you retain employees?" What condition must be true to justify surveying only a sample of the managers instead of surveying the entire population of managers?
The population is small.
The population is diverse.
The population is not the target of the survey question.
The population is expensive and time-consuming to survey.
I believe it is "The population is expensive and time-consuming to survey"
It is a large population, and conducting a census would be challenging.
Answer:
"The population is expensive and time-consuming to survey"
Step-by-step explanation:

Hazel is putting together charm bracelets. For each bracelet 1/5 of a yard of string and 12 charms. hazel has 5/8 of a yard of string and 96 charms. she makes the charm bracelet until all of the string is gone. what fraction of charms did she use?
Answer:
3/8
Step-by-step explanation:
First, find the number of bracelets she's able to make with her string. She has 5/8 of a yard and uses 1/5 per bracelet. To divide the number of yards she has by the number she uses, multiply 5/8 by the reciprocal of 1/5 (5/1).
5/8 * 5/1 = 25/8
25/8 is 3.12500, which is the number of bracelets she can make. It rounds down to 3 since she can't make 0.12500 bracelets.
Now, find how many charms she used. 3 bracelets * 12 charms each is 36 charms in total.
So she used 36/96 of her charms. This can be simplified to 3/8.
Answer:
37/96 hazel has
Step-by-step explanation:
1/5 times 12=60
so Hazel uses 1 yardd for 60 charms, so for 5/8 yard Hazel would use 5/8×60=37.5.
since Hazel isn't able to use a fraction of a charm, she would use 37 charms
37/96 Charms Hazel has
Charlie bought pound of American cheese and pound of Swiss cheese. Josh bought pound of cheddar cheese and pound of jack cheese. Josh says that they bought the same amount of cheese. Is he correct? Explain.
Answer: It is not possible to determine whether Josh is correct without more information. In order to determine whether they bought the same amount of cheese, it would be necessary to know the weight of the cheeses that Charlie and Josh bought. If the weight of the cheeses that Josh bought is equal to the weight of the cheeses that Charlie bought, then Josh is correct and they did buy the same amount of cheese. However, if the weight of the cheeses that Josh bought is not equal to the weight of the cheeses that Charlie bought, then Josh is incorrect, and they did not buy the same amount of cheese.
Step-by-step explanation: It's hard to say because you would need the weight of the cheese.

Noah bought stock in a company two years ago that was worth x dollars. During the first year that he owned the stock, it increased by 31%. During the second year the value of the stock increased by 15%. Write an expression in terms of x that represents the value of the stock after the two years have passed.
Answer:
1.5065x
Step-by-step explanation:
x + (0.31x) + 0.15(1.31x)
x is the initial amount, 0.31x is the 31% of the original amount, and we're adding that. The 15% earned the next year is on the new total of what he had after that first bump...x + 0.31x = 1.31x
Simplify:
x + (0.31x) + 0.15(1.31x)
= 1.31x + 0.1965x
=1.5065x
