The Spanish club held a car wash to raise money why equals Y=5X represents the amount of money The Y club members made Washing cars identify the constant Proportionality
Answers
Given:
The amount of money y club members made for washing x cars is
[tex]y=5x[/tex]
To find:
The constant Proportionality.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is constant of proportionality.
The amount of money y club members made is proportional to number of cars washing x.
We have,
[tex]y=5x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]k=5[/tex]
Therefore, the constant proportionality is 5.

what happens when you multiply each side of the inequality by a negitive number
Answers
Answer:
What happens when you multiply each side of the inequality by a negative number?
Much like when you divide by a negative number, the sign of the inequality must flip. When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!
Does the inequality sign change when multiplying by a negative?
Because we are multiplying by a negative number, the inequalities change direction.
What is the rule for negatives and inequalities?
If a < b and if c is a negative number, then a · c > b · c. Multiplying each side of an inequality by a negative number reverses the direction of the inequality symbol. Dividing each side of an inequality by a negative number reverses the direction of the inequality symbol.
Examples of inequality by a negative number
3x < 7+3
Multiply (or divide) both sides by a negative number. Swapping left and right-hand sides.

An open top box is made from a rectangular piece of cardboard, whose length is twice the width, by cutting a 3 in square from each corner and folding up the remaining sides. The area of the bottom of the box is 140 inches squared. What is the width?
Answers
Answer:
Width = 13 inch
Step-by-step explanation:
Assume;
Width = x
Length = 2(width) = 2x
Cut 3 inch from each corner:
Width = x-3-3 = x - 6
Length = = 2x-3-3 = 2x - 6
Area of rectangle = lb
Area of rectangle = [length][width]
Area of rectangle = (2x - 6)(x - 6)
Area of rectangle = (2x - 6)(x - 6)
140 = 2x² - 12x - 6x + 36
2x² - 18x - 104
x² - 9x - 52
x² - (13-4)x - 52
x² - 13x + 4x -52
x(x-13)+4(x-13)
(x-13)(x+4)
So,
x = 13 or x = 4
Width = 13 inch

Critique the the reasoning of others. Connor determines the slope between (-2,4) and (3,-3) by calculating 4 -(-3)/ -2 - 3. April determines the slope by calculating 3 - (-2) / -3 - 4. Explain whose reasoning is correct.
Answers
Answer:
Connor's
Step-by-step explanation:
According to the slope formula, it is (y2 - y1)/(x2 - x1)
Connor uses the y-values first and put them on the numerator, and that is what you are meant to do, unlike, April. She puts the x-values on top and the y-values on the bottom.

Yousef is cutting pieces of construction paper so he can make cards for his family. Each piece of paper is 1112 inches wide. If he cuts that width so he would have two equal-sized smaller pieces, how wide will each smaller piece be?
Answers
Answer:
556 inches
Step-by-step explanation:
Given that:
The width of the construction paper is 1112 inches wide ;
Cutting the width to obtain two equal sized smaller pieces ;
(Width size of the original construction paper ÷ Number of smaller pieces)
= (1112 inches ÷ 2)
= 556 inches.
Hence, the smaller pieces will be 556 inches wide.

Answer:
Length of boat = 12,000cm
Scale: 100cm : 1m
Step-by-step explanation:
Find the diagram attached
Given
Length of the boat = 120m
Using the conversion
100cm = 1m
Converting to 120m to centimeters
x cm = 120m
100cm = 1m
Cross multiply
x×1 = 120×100
x = 12,000cm
.
Hence the length of the measured segment is 12,000cm
The scale used will be according to the conversion rate used
The scale used will be 100cm : 1m
Answer:
The actual answer is:
Length if the segment is 4 centimeters.

7x + 39 ≥ 53 AND 16x + 15 > 31
CHOOSE ONE ANSWER
x > 1
x ≥ 2
x ≤ 2
There are no solutions
All values of x are solutions
Answers
first, we’ll focus on the first inequality. to isolate the variable, x, we have to subtract 39 from each side
7x + 39 > 53
7x > 14
now divide by 7
x > 2 (x is greater than or equal to 2)
for the second inequality, isolate the variable by subtracting 15 from each side and then dividing by 16
16x + 15 > 31
16x > 16
x > 1
so the answer put together would be x > 1 & x > 2
because x>2 falls under the category of x > 1 (2 is greater than 1 and can be a valid answer for this), the answer is x > 1 because it applies to both inequalities’ values

How can you solve one-step multiplication and division equations?
Answers
Answer:
Step-by-step explanation:
All of these equations only require a single operation before you get x alone. for example: x - 2 = 6 Compared with 2x = 6
For the first one, you have to add two and get x = 8. for the second one, Then you divide by 2 and get x = 3. they're both a single step, as the name "one-step" equations tells you, and you only have to divide, multiply, add, or subtract one value.
