Answer:
24 cm, 21 cm
Step-by-step explanation:
Let the width of the rectangle be x cm
So, length = x + 3 cm
Perimeter of rectangle = 90
2(x + 3 + x) = 90
(2x +3) = 90/2
2x + 3 = 45
2x = 45 - 3
2x = 42
x = 42/2
x = 21 cm
x + 3 = 21 + 3 = 24 cm
Length = 24 cm
Width = 21 cm
Hence, dimensions of the rectangle are 24 cm and 21 cm.
A student bought shoes online. The total cost, t, of the pairs of shoes, s, can be found by the function below. If the student spent $569.37 on shoes, how many pairs did he buy?
t = 62.50x +7.23
Answer:
D 9
Step-by-step explanation:
569.37 = 62.50x + 7.23
562.14 = 62.5x
x = 9.04 so 9 pairs
The student bought 9 pairs of shoes.
What is a function?"It defines a relation between one variable and another variable."
What is a linear function?"It is a function of the form f(x) = ax + b, where a, b are real numbers."
For given example,
The total cost, t, of the pairs of shoes, 'x', can be found by the linear function below.
t = 62.50x +7.23
the student spent $569.37 on shoes,
⇒ t = $569.37
We need to find the number of pairs of shoes the student bought.
Substitute t = 569.37 in the given linear function and find the value of 'x'
⇒ 569.37 = 62.50x + 7.23
⇒ 562.14 = 62.50x
⇒ x = (562.14) / (62.50)
⇒ x = 8.99
⇒ x ≈ 9
Therefore, the student bought 9 pairs of shoes.

2) -8(-8x - 6) = -6x – 22
Answer:
x = -1
Step-by-step explanation:
-8(-8x - 6) = -6x - 22 {Use distributive property}
(-8) * (-8x) - 6 *(-8) = -6x - 22
64x + 48 = -6x -22 {Add 6x to both sides}
64x + 6x + 48 = -22 {Subtract 48 from both sides}
70x = -22 -48
70x = -70 {Divide both sides by 70}
x = -70/70
x = -1

50 points to whoever is right and brainliest. The graph shows a proportional relationship. Which equation matches the graph?
Answer:
B. y = 3xStep-by-step explanation:
Use one of the points on the graph to find the equation.
Let's take the point (1,3)
We know the proportional relationship is:
y = kx, where k is the coefficient of proportionalitySubstitute the values from the point and solve for k:
3 = 1*kk = 3The function is:
y = 3xCorrect choice is B
Answer:
The graph is in a proportional relationship (given)
Therefore, it is in the form y=kx where k is a constant.......(i)
Now in the graph we can locate that when the value of x is 1, the value of y will be 3
Putting the value of x and y in equation (i), we get
3=1×k
k=3
Now, putting the value of k in equation (i), we get
The equation of the graph is y=3x.
