Step-by-step explanation:
Given the system of equations,
[tex]y=2x-3\\y=-x+3[/tex]
We can substitute one equations into another since both equations solve for y. I will use the second equation for this example.
Step 1: Substitute
[tex]-x+3=2x-3[/tex]
Step 2: Simplify
[tex]6=3x\\x=2[/tex]
Now, we can easily substitute our x value into one of the equations.
Step 3: Substitute.. again
[tex]y=-2+3\\y=1[/tex]
Solution: [tex](2,1)[/tex]

y = ___
Answers
Answer:
17.5
Step-by-step explanation:
x=2
y=7
when y by x, then multiple y by 5.
7/2= 3.5
3.5×5= 17.5
you can also do 7x2 which would give you 14 and then divide 7 by 2 to get 3.5, and add the two together, so 14+3.5=17.

Answers
Answer:
13
Step-by-step explanation:
if there are 5 tanks and 65 fish in all the tanks together, you take 65 and divide it by 5 to get 13 fish in each tank
: )
Answer:
10.84.
Step-by-step explanation:
To find the constant of proportionality, we can use the fact that the relationship between the number of fish and fish tanks is proportional. This means that the ratio of the number of fish to the number of fish tanks is always the same.
From the graph, we can see that when there are 65 fish, there are 5 fish tanks. When there are 52 fish, there are 6 fish tanks. Let's use these two data points to find the constant of proportionality:
The constant of proportionality = (Number of fish) / (Number of fish tanks)
For the first data point, we have:
65 / 5 = 13
For the second data point, we have:
52 / 6 = 8.67
We can see that these two values are not the same, which means that the relationship between the number of fish and the number of fish tanks is not exactly proportional. However, we can still find an average constant of proportionality between these two values:
(13 + 8.67) / 2 = 10.84
So the constant of proportionality, in terms of the number of fish per fish tank, is approximately 10.84.

108 is 36% of what number? Write and solve a proportion to solve the problem.
Answers
108/n = 36/100
Next write the cross products. So, 36n = 108 x 100 = 10,800
divide each side by 36.
36n/36 = 10,800/36
Lastly simplify. Which will be, n = 300.
so my answer is 108 is 36% of 300.
1. Take the percentage (36%) and change it to a decimal (.36)
2. Set up the equation.
.36x = 108
3. Divide both sides by .36
x = 300

Step-by-step explanation:
This figure can be thought of as a rectangle 4 cm by 8 cm in the middle and one triangle on the left side and a congruent triangle on the right side. The triangles have 8 cm bas and 2 cm height.
total area = area of rectangle + 2 × area of triangle
total area = (4 cm)(8 cm) + 2 × (8 cm)(2 cm)/2
total area = 48 cm²

PLEASE HELP ME :DDDDDDDDDDDDDD
Answers
Answer:
Step-by-step explanation:
To find the area of a rectangle, you multiply the length by the height.
First, we need to convert the mixed numbers to improper fractions:
Length: 6 3/4 ft = (6 x 4 + 3) / 4 ft = 27 / 4 ft
Height: 2 2/12 ft = (2 x 12 + 2) / 12 ft = 26 / 12 ft = 13 / 6 ft
Now we can calculate the area:
Area = Length x Height
Area = (27 / 4) ft x (13 / 6) ft
Area = 351 / 24 ft^2
Area = 14 11/24 ft^2
Therefore, the area of the rectangle is 14 11/24 square feet.

Combine like terms to simplify the expression below.
12(6x+4)+5x−8
Answers
First you’d need to distribute the 12 in order to begin combining like terms.
72x + 48 +5x -8
Circle which have an exponent which would be 72x and +5x which would be 77x
Box the numbers without exponents and combine those 48 -8 which equals 40
77x + 40
There is no number that these two share so there is no way for them to be simplified so your answer is just 77x + 40.
Distribute the 12 to the 6x and 4.
72x + 48 + 5x - 8
Combine 72x and 5x since they both have the variable x.
77x + 48 - 8
Combine 48 and 8 because they both have no variable
77x + 40
