Answer:
x= -2
Step-by-step explanation:
21x-7-12x-6=8x-16+1
9x-13=8x-15
x+2=0
x=-2
Answer:
x=10
Step-by-step explanation:
7(3x-1)-6(2x+3)=8(x-2)+1
= 21x-7-12x-18=8x-16+1
Move the 8x to the other side and combine like terms.
= x-25=-15
Move the -25 to the other side
x= -15+25
x=10

Amanda buys 4 tickets to the baseball game for $24 each. Which equation
shows the closest estimate of the total amount Amanda spends?
Which equation shows the closest estimate of the total amount Amanda spends
Answer:
$96
Step-by-step explanation:
Given that,
The total number of tickets = 4
Cost of each baseball = $24
We need to find the equation that shows the closest estimate of the total amount Amanda spends.
Total cost = No. of tickets × Cost of each baseball
= 4×24
= $96
Hence, the total cost is $96.
The soccer team is planning to sell health bars for a fundraiser. The prices of purchasing health bars from two different companies are represented by the system of equations shown, where x is the number of bars purchased and y is the total cost in dollars. Company A: y=0.75x Company B: y=10+0.50x How many bars would the team need to purchase from each company in order for the total cost to be equal?
Answer:
40 bars
Step-by-step explanation:
Where x = Number of bars purchased by each team
We solve this question by equating both Equations from Company A to Company B
Company A = Company B
0.75x = 10 + 0.50x
Collect like terms
0.75x - 0.50x = 10
0.25x = 10
x = 10/0.25
x = 40 bars
Hence, each team need to purchase 40 bars from each company

Help! I need some explanation here!
Answer:
So its is pretty straight forward (answer at the bottom)
First of all 2 sides of a parrleogram are the dame and the other 2 are different from the first but the opposites are the same
So lets start with The distance from home to bank
x+9 is the distance since its the opposite
Now the other side is 2x+1
The third side is x+9
the fourth side is x+5, it is different from 2x+1 but its just written differently.
Now add them all up
2x+1+x+9+x+5+x+9=
5x+24
So the amount fo meters are 5x+24
The distance covered by Amaia is 5x+24 meters.
What is a parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Given that, Amaia walks out and covers a distance in a shape of parallelogram,
Therefore, the opposite sides will be equal,
To find the distance covered we will find the perimeter of the parallelogrammical way,
P = x+9+x+9+x+5+2x+1
P = 5x+24
Hence, the distance covered by Amaia is 5x+24 meters.

Answer:
The missing value is 6!
Step-by-Step Explanation:
First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)
Now, we can write this as a function, where we can represent the missing value as 'x'.
[tex]4+5+13+x=28[/tex]
In order to get the missing value, we must solve the equation.
Step 1: Simplify.
[tex]4+5+13+x=28\\22+x=28[/tex]
Step 2: Subtract 22 from both sides.
[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]
x is equal to 6, which means the missing volume of gas is 6!

11 = 7 + 4x is what is what is what
Answer:
x = 1
Step-by-step explanation:
11 = 7 + 4x
Subtract 7 from both sides
11-7 = 7-7 + 4x
4 = 4x
Divide 4 from both sides
4/4 = 4x/4
1 = x
x = 1
Check:
11 = 7 +4(1)
11 = 7+4
11 = 11

Seema is travelling to Kenya. She travels a distance of 8,300 km by plane to Lagos and then another 5,500 km to Nairobi. Both planes fly at an average speed of 1,200 kmh-1. What is her total flight time in hours and minutes, to the nearest minute?
Answer: 11 hours 30 minutes
Step-by-step explanation:
Total flight distance:
= 8,300 + 5,500
= 13,800 km
Flight time = Distance / Speed
= 13,800 / 1,200
= 11.5 hours
= 11 hours 30 minutes

A stack of books is 5 feet 5 inches high. How high is it in inches?
Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.
Answer:
Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches
Teresa is going with her family to watch
professional barrel racers. Her family
buys 6 tickets. They have a coupon for
$1.50 off each ticket. They pay $52.50
altogether for their tickets. Write an
equation that you could use to represent
the situation. What is the price of a ticket
before using the coupon?
Answer:
6 * (x - 1.50) = 52.50 ; 10.25
Step-by-step explanation:
Given that :
Number of tickets purchased = 6
Coupon off per ticket = 1.50
Total Amount paid for tickets = $52.50
Let x = initial price of ticket :
Number of tickets purchased * (Initial ticket price - coupon) = total amount paid
6 * (x - 1.50) = 52.50
6x - 9 = 52.50
6x = 52.50 + 9
6x = 61.50
x = 61.50 / 6
x = 10.25
Hence, initial price of ticket = $10.25

Complete the pairs of corresponding parts if △RST ≅ △TXY.
∠STR =
∠ XYT
∠ TXY
∠ XTY
Answer:
∠STR is associated with ∠ XYT
Therefore, we conclude that:
∠STR = ∠ XYTStep-by-step explanation:
Given
△RST ≅ △TXY
To determine:
∠STR = ?
As
△RST ≅ △TXY
So the triangles △RST and △TXY are congruent to each other.
We know that congruent triangles have equal corresponding parts.Please check the attached graph.
From the graph, it is clear that:
∠STR is associated with ∠ XYT
so
∠STR = ∠ XYT
Therefore, we conclude that:
∠STR = ∠ XYT
