Answers

Answer:

Negative 140 divided by negative 7 = 20

Step-by-step explanation:

Gena and her friends each estimated the quotient of –137.56 divided by –6.12 using compatible numbers.

Using Compatible Numbers: we round up each negative number given to the nearest whole number.

Hence:

-137.56 = -140

-6.12 = -7

Hence:

-140/-7 = -20

Therefore, the best estimate using compatible numbers is Negative 140 divided by negative 7 = 20

Step-by-step explanation:

first, we multiply the 8(x - 2)

8 times x = 8x

8 times - 2 = -16

8x - 16 - 4 = 28

-16 - 4 = -20

8x -20 = 28

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.

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.

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

x > 1

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

ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. In kilometers, how far did Jada run in 60 minutes ?
PLZZZZZ HELP ASAP

Answers

Answer:

They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.

Step-by-step explanation:

Let's first calculate the speed of each person using the units provided so that we  do not complicate the question.

speed =  distance covered/time taken

Andre's speed = 2 km/15 min = 0.133 km/min

Jada's speed = 3km/20 min = 0.15 km/min

Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.

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

Answers

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.

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.

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.
