Kendra's charge per car in the toy store is $1.8.
What is the system of equations?"Systems of equations, sometimes called simultaneous equations, are a group of relationships between various unknown variables that can be expressed in terms of algebraic expressions".
For the given situation,
Let the number of cars be 'x' and
The number of candy be 'y'
$5.00 for two cars and one piece of candy
$3.2 for one car and one piece of candy
System of the equation for the above case
Equation 1:
[tex]2x + y = 5[/tex]
Equation 2:
[tex]x + y = 3.2[/tex]
Subtract equation 2 from equation 1,
⇒ [tex]x=1.8[/tex]
On substituting x in equation 2, we get
⇒ [tex]y=3.2-1.8[/tex]
⇒ [tex]y=1.4[/tex]
Hence we can conclude that Kendra's charge per car is $1.8.

IF YOU ANSWER THESE TWO I'LL GIVE BRAINLIEST (if you only answer one no brainliest)
Answer:
The first question provided (question 11)
The answer is $118.00
The second question provided (question 12)
The answer is 20 seconds
Step-by-step explanation:
The first question provided (question 11)
The equation 5a + 3c is provided to determine the cost of a catering event, where a is the number of adults and c is the number of children.
It is stated that there are 17 adults and 11 children attending an event.
You can substitute in the 17 adults in place of a and the 11 children in place of c.
This will leave you with 5(17) + 3(11).
If you simplify you will get 85 + 33, which is equal to 118
Therefore, the answer is $118.00.
The second question provided (question 12)
The equation s = 5w is provided to determine how far behind a clock is after a certain amount of time, where s is seconds behind and w is the number of weeks sice the clock was last set.
You are given the clock was set 4 weeks ago.
You can subsitute the 4 weeks into the equation in place of variable w.
This leaves you with s = 5(4).
Simplifying this further, you will get s = 20.
Therefore, the clock is 20 seconds behind.
What is the value of p?
Answer:
p=25
Step-by-step explanation:
Both angles that contain p are equal to eachother. SO we can set 3p equal to p+50. 3p=p+50
After doing this we get 25° for p.

Find the value of x.l
Answer:
The value of x is 28°
Step-by-step explanation:
2x + 1 and 33° together forms 90° angle.
So, we need to find the angle at the 2x + 1.
--> 90° - 33°
= 57°
So, 2x + 1 gives 57°.
So, to find x :-
2x + 1 = 57°
2x = 57 - 1
2x = 56
x = [tex]\frac{56}{2}[/tex]
x = 28

The rabbit population in a certain area is 200% of last year’s population. There are 1,100 rabbits this year. How many were there last year?
Answer:
1100/2 = 550
Step-by-step explanation:
A percent increase of 200% is equal to multiplying by 2. Therefore, we can divide by two to reverse the increase.

Jalen is trying to set a pole that is 10 ft long into the ground so that it is perpendicular with the horizontal surface. Jalen locates a point 6 feet from the base of the pole, at C, and labels it A then he measures the distance from point a to b what distance to the nearest tenth of a foot does haley need for the pole to be perpendicular
Answer:
The distance from point A to B that Haley needs for the pole to be perpendicular is:
11.66 feet.Step-by-step explanation:
To solve this exercise, imagine that it is a triangle, where the height is the pole, which is 10 feet, and the base of the triangle is the distance between the base of the pole and the point located by Jalen and called C, which it would have a measurement of 6 feet, finally, the measurement between A (the point located six feet) and B (the highest part of the pole) would correspond to the hypotenuse of a triangle,
Therefore, having these two measures, you could use the Pythagorean theorem to find the hypotenuse of a triangle with those measures and solve it, remember that the Pythagorean theorem is:
Hypotenuse^2 = opposite leg^2 + adjacent leg^2We replace the values given in the exercise:
Hypotenuse^2 = (10 ft)^2 + (6 ft)^2Hypotenuse^2 = 100 ft^2 + 36 ft^2[tex]\sqrt{hypotenuse^{2} }[/tex] = [tex]\sqrt{100 ft^{2} +36ft^{2} }[/tex]Hypotenuse = [tex]\sqrt{136ft^{2} }[/tex]Hypotenuse = 11.66 ft approximately.In this form, Jalen can be sure the pole is perpendicular to the ground when the distance from point A to B is 11.66 ft approximately.

what is the average rate of change of the population between 1930 and 1950? show your reasoning?
Answer:
The average rate of change is: 0.25
Step-by-step explanation:
Given
See attachment for graph
Required
The average rate of change between 1930 and 1950
Average rate of change (m) is calculated as:
[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]
In this case,
[tex][a,b] = [1930,1950][/tex]
So, we have:
[tex]m = \frac{f(1950) - f(1930)}{1950 - 1930}[/tex]
[tex]m = \frac{f(1950) - f(1930)}{20}[/tex]
From the attached graph;
[tex]f(1950) = 45[/tex]
[tex]f(1930) = 40[/tex]
So, we have:
[tex]m = \frac{45- 40}{20}[/tex]
[tex]m = \frac{5}{20}[/tex]
[tex]m = 0.25[/tex]

2 - x = x - 8
ayudaaa
porfavor
Answer:
x=5
Step-by-step explanation:
2 - x = x - 8
- x = x - 8 - 2 (subtract 2 from both sides)
- x = x - 10 (combine like terms)
- 2x = - 10 (subtract x from both sides)
x = 5 (divide each side by -2).
Answer:
x = 5
Step-by-step explanation:
2 - x = x - 8
- x + 2 = x - 8
- x + 2 - 2 = x - 8 - 2
- x = x - 10
- x - x = x - x - 10
- 2x = - 10
- 2x ÷ - 2 = - 10 ÷ - 2
x = 5
