A group of friends wants to go to the amusement park. They have $60 to spend on parking and admission. Parking is $18, and tickets cost $10.50 per person, including tax. How many people can go to the amusement park?
Answer:
4 people
Step-by-step explanation:
plug 18+10.5x into your calculator, or just make a table labelling x and y.
note that x must not exceed $60 but can be equal to or less than $60. x=4 gives you the exact number of people, which is 4.

A number z times 3 is at most -4.8
Answer and you’ll get brainliest answer if correct!
Answer:
3z < -4.8
* be sure to use the less than or equal to sign
Step-by-step explanation:
The inequality for the A number z times 3 is at most -4.8 is 3x < -4.8
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
A number z times 3 is at most -4.8
Now, the mathematical expression is
3z < -4.8
and, z< -1.6
Hence, the inequality is 3x < -4.8

Given the table of values that represents a linear function, the value of y when x = 4 is: 5.
Recall:
Equation of a linear function can be modelled as y = mx + b.m = slope; b = y-intercept.slope (m) = change in y / change in xy-intercept (b) is the value of y at x = 0.Find the slope of the linear function, using two pairs of values, (-4, 3) and (0, 4):
Slope (m) = (4 - 3)/(0 - (-4)) = 1/4
y-intercept (b) = 4 (from the table, when x = 0, y = 4).
Write the equation that models the function by substituting m = 1/4 and b = 4 into y = mx + b:
y = 1/4x + 4
Thus, to determine the value of y when x = 4, substitute x = 4 into y = 1/4x + 4:
y = 1/4(4) + 4
y = 1 + 4
y = 5.
Therefore, given the table of values that represents a linear function, the value of y when x = 4 is: 5.

The measure of an angle is 17.3°. What is the measure of its complementary angle?
Answer:
72.7
Step-by-step explanation:
complementary angles: either of two angles whose sum is 90°.
90-17.3 = 72.7
Answer:
Complementary angle of 17.3° is (90°-17.3°)=72.7°
72.7° is the right answer.Move the number that is not next to the variable to the other side of the equation by using the opposite operation Divide by the number next to the variable 8x -1 = -50
Given:
The equation is
[tex]8x-1=-50[/tex]
To find:
The value of x by separating the variable.
Solution:
We have,
[tex]8x-1=-50[/tex]
Here, -1 is not next to the variable. So, move -1 to the other side of the equation by using the opposite operation. After moving -1 to the right side of the equation it will become +1.
[tex]8x=-50+1[/tex]
[tex]8x=-49[/tex]
Divide both sides by 8.
[tex]x=\dfrac{-49}{8}[/tex]
Therefore, the value of x is [tex]\dfrac{-49}{8}[/tex].

Add 8 to both sides:
-3x - 8 > 19

Dividing by a negative number on each side switches the inequality:
x < -9

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as -
8/10 + 2/6
The given expression is -
8/10 + 2/6
(2 x 4)/(2 x 5) + (2 x 1)/(2 x 3)
4/5 + 1/3
(12 + 5)/15
17/15

Answer:
The price of each big peach is: $0.45
Step-by-step explanation:
Given that
Total peaches = 270
The ratio of small to medium to big peaches
2:4:3
We can use this ratio to find the number of peaches in each group
First of all we have to find the sum of ratios
That is
2+4+3 = 9
Now
[tex]Small\ peaches = \frac{2}{9} * 270 = 60\\Medium\ peaches = \frac{4}{9}*270 = 120\\Big\ peaches = \frac{3}{9} *270 = 90[/tex]
It is also given that total cost is $91.50
We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.
So,
Price of one small peach = $0.25
Total cost = 0.25*60 = 15
Price of one medium peach = $0.30
Total cost = 0.30*120 = 36
[tex]Price\ of\ all\ medium\ peaches = Total\ cost-(Cost\ of\ small\ peaches+ Cost\ of\ medium\ peaches)\\= 91.50 - (15+36) \\=91.50-51\\=40.5[/tex]
To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches
So,
[tex]Cost\ of\ one\ peach = \frac{40.5}{90} = 0.45[/tex]
Hence,
The price of each big peach is: $0.45
0.45 cent
Given that
Total peaches = 270
The ratio of small to medium to big peaches.
2:4:3
We can use this ratio to find the number of peaches in each group
First of all we have to find the sum of ratios
That is
2+4+3 = 9
It is also given that total cost is $91.50
We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.
So,
Price of one small peach = $0.25
Total cost = 0.25*60 = 15
Price of one medium peach = $0.30
Total cost = 0.30*120 = 36
To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches.
So the price of each big peach is: $0.45
