Becky is using the expression 2z + 3 to represent the number of chairs in her classroom. There are twice as many chairs as tables, and there are three extra chairs in the back. What does z represent?
The number of chairs.
The number of tables.
The number of chairs at tables.
The number of chairs and tables.
Answer:
The number of chairs
Step-by-step explanation:
The equation is 2z + 3
2 ( = multiply by)
z ( # of chairs)
+3 ( the 3 extra chairs in the back)
Answer:
The number of tables
Step-by-step explanation:
Sens there is twice as many chairs as tables, the number 2 represents the chairs. The 3 represents the 3 extra chairs in the back. so the only logical object to represent z is the number of tables.
Cheyenne is making a recipe that uses 5 cups of beans and 2 cups of carrots. Which combination below uses the same ratio of beans to carrots?
I need help I don’t know what to do!?
Answer:
The slope is 4/3x
Step-by-step explanation:
We can easily find the slope, by looking at the difference between each number on the table. We can see that the x values are rising in 3's, and the y values are rising in 4's. From that we can find the slope, 4/3x, since the slope rises up positive 4, and runs positive 3.
EDIT: forgot the x after the slope

a baseball team has won 25 games and lost 12 games. if the baseball teams rate continue through a 148 game season, then how many games will they have won?
Answer:
100 games won
Step-by-step explanation:
1. 25 games won and 12 games lost is a total of 37 games
2. If you're comparing the 25 games out of 37 games won to a total of 148 games played and trying to find the number of games won you would multiply 25 times 148 divided by 37

A polygon has a perimeter of 18 units. It is dilated with a scale factor of 3/2 what is
the perimeter of its image?
Answer:
A
Step-by-step explanation:
Is the correct answer
The perimeter of the polygon after dilation = 27 unit
What is dilation factor?The scale factor in a mathematical object's dilatation defines how much the picture will grow or shrink in relation to the original thing.
The perimeter of polygon = 18 unit,
Since, the scaling factor is 3/2,
So when the polygon is dilated, the perimeter of the polygon will also multiply with 3/2,
Perimeter of polygon = 18×3/2
= 27 unit
The perimeter of the polygon after dilation = 27 unit

You buy 4 balloons and 2 banners for $8. Your friend buys 6 balloons and 1 banner for $8.
Each balloon costs ?$
and each banner costs ?$
Answer:
Each balloon costs $1
Each banner costs $2
Step-by-step explanation:
First of all, let's write down the equation from this problem.
Let "y" be the cost of the ballon, and let "x" be the cost of a banner. Then the following is true from the question...
4y + 2x = 8
6y + x = 8
Now since both of them are equal to 8 both of them are equal to each other, and so we can get the following equation...
4y + 2x = 6y + x
2x - x = 6y - 4y
x = 2y
Now if we substitute 2y instead of x in one of the previous equations we will obtain...
6y + x = 8
6y + 2y = 8
8y = 8
y = 1
From the equation x = 2y we know that...
x = 2y
x = 2(1)
x = 2
The vertex of this parabola is at (-3,-1). When the yvalue is 0, the x-value is 4. What is the coefficient of the squared term in the parabola's equation?

At a restaurant, the cost for one breakfast taco and one glass of milk is $2.10.
The cost for two tacos and three glasses of milk is $5.15.
How much would it cost for 3 tacos and 4 glasses of milk
Answer: $7.25
Step-by-step explanation:
Let T = taco cost
Let M = milk cost
T + M = 2.10
2T + 3M = 5.15
Multiply the first equation by (-2) and add it to the second equation
-2T - 2M = -4.20
2T + 3M = 5.15
M = 0.95
Plug this value for M in to the first equation
T + 0.95 = 2.10
T = 1.15
So a taco costs $1.15 and the milk costs $0.95
1.15 * 3 = 3.45
0.95 * 4 = 3.80
3.45 + 3.80 = 7.25
