Step-by-step explanation:
you have to divide it so 7 1/2 ÷ 1 1/2
15/2 × 3/2 then you swap the 3/2 to 2/3 so it will be 15/2 × 2/3 you don't have to cross multiplication so you just multiply across so it would be 15×3=30 and then 2×3=6 so it would be 30/6 but that's not the final answer because it and improper fractions so you divide 30÷6=5 and that's how you get 5

Answer:
c = 0
Step-by-step explanation:
You want the value of c such that point (c, 4) is on the line with slope 1 through point (-7, -3).
Point-slope equationThe point-slope equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
The line with slope 1 through point (-7, -3) has equation ...
y +3 = 1(x +7)
y = x +4 . . . . . . . subtract 3 and simplify

Using inequality, we know that the maximum number of students that can visit the amusement park is 30.
What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.Make use of the following steps to solve an inequality: Step 1: Remove fractions by multiplying all terms by the fractions' lowest common denominator. Step 2 Combine like terms on both sides of the inequality to simplify. Step 3 Obtain the unknown on one side and the integers on the other by adding or subtracting quantities.So, inequality represents the maximum number of students who can go to the amusement park:

A linear equation for the trend line in this scatter plot is y = 4x/3 - 5/3.
How to determine the equation of this line?In order to determine a linear equation for the trend line (line of best fit) that models the data points contained in the scatter plot, we would have to determine its slope by using the points that trend line passes through.
Mathematically, the slope of a straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Based on the information provided in the scatter plot, the trend line passes through the following points:
Points (x, y) = (5, 5)Points (x, y) = (8, 9)Substituting the given points into the formula, we have;
Slope, m = (9 - 5)/(8 - 5)
Slope, m = 4/3
At point (5, 5), a linear equation for the line can be calculated by using the point-slope form:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y represent the points.c represent the y-intercept.Substituting the given points into the formula, we have;
y - y₁ = m(x - x₁)
y - 5 = 4/3(x - 5)
y - 5 = 4x/3 - 20/3
y = 4x/3 - 20/3 + 5
y = 4x/3 - 5/3

find the length of one side of a solid cube given that its
volume is 8 cm cube
total surface area is 54 cm square.
Step-by-step explanation:
I assume you mean as second question "what is the volume of a cube with the surface area of 54 cm² ?".
first question :
volume is 8 cm³
the volume of a cube is side³.
8 cm³ = side³
side = cubic root(8) = 2 cm
add-on : the surface of a cube (6 sides) is 6 times the area of side² squares.
surface = 6 × 2² = 6 × 4 = 24 cm²
second question :
54 cm² = 6 × side²
9 = side²
side = sqrt(9) = 3 cm
and the volume would be
side³ = 3³ = 27 cm³

The sum of the interior angles of a tringle is 180°. The smaller tringle on the right adds up to 180.
One angle is 90, that is the angle that has a small square. Another angle is 55 so the last angle needs to be 35 (90+ 55+35 = 180)
The larger triangle is 25 (90 + 55 + 10 + 25 = 180)

A jar of sweet pickles contains 650 grams of pickles. There are 12 jars in a case. How many kilograms of pickles are in a case?
In the figure below, m<1(15x-5)° and m<3(10x + 35)Find x =and m <2 =
1) You have the following expressions for angles ∠1 and ∠3
m∠1 = 15x - 5
m∠3 = 10x + 35
In order to find the value of x, you consider that angle ∠1 and ∠3 are congruent, that is, they are equal. Then, you equal the algebraic expressions and solve for x, just as follow:
15x - 5 = 10x + 35 subtract 10x bith sides, add 5 both sides
15x - 10x = 35 + 5 simplify similar terms
5x = 40 divide between 5 both sides
x = 40/5
x = 8
Hence, x = 8, and the values of the angles are:
m∠1 = 15x - 5 = 15(8) - 5 = 115
m∠3 = 10x + 35 = 10(8) + 35 = 115
2) To find the measure of the angle ∠2 you consider that the sum of angles ∠1 and ∠2 is equal to 180°. Thus, you obtain:
m∠1 + m∠2 = 180°
m∠2 = 180 - m∠1 = 180 - 115 = 65
Hence, the measure of angle m∠2 = 65°
