Answer: -1
Step-by-step explanation:
3( x +7 ) =18
8Use distributive property
3x + 21 = 18
Substract 21 from both sides
3x = -3
Divide 3 by both sides
x = -1
Another way to solve:
3( x +7 ) =18
Divide 3 by both sides
x + 7 = 6
Substract 7 by both sides
x = -1
Answer:
x = -1
Step-by-step explanation:
In order to answer this question, all we have to do is simplify the equation:
3(x + 7) = 18
3x + 21 = 18
-21 -21
3x = -3
/3 /3
x = -1
You can even put this answer in the equation to check.

Determine the constant of proportionality, k, and interpret it in the context of each problem. 2) The graph shows the relationship between the number of euros Jason received and the number of dollars Jason exchanged during his trip to Spain. *
The constant of proportionality Or the value of Euros is 3/2 times of the value of a dollar.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
To obtain the constant of proportionality we'll need to determine at least two coordinate points from the graph they are, (1, 3/2) and (2, 3).
Let, no. of dollars be 'x' and no. of euros be 'y'.
So, y = kx.
3/2 = k.
Another way is (3 - 3/2)/(2 - 1).
= (3/2)/1
= 3/2.

Also:
x can take a whole number or decimal numbers
i.e. You can climb for 1 hour, 2 hours or part of an hour
When a data can take decimal, then such data is continuous.
Hence, the domain is continuous

Angela wants to purchase carpeting for her living room. The dimensions of her living room are 15 feet by 18 feet. If carpeting is sold by the square yard, determine how many square yards of carpeting she must purchase.
Answer: 15 square yards of carpeting.
Hope this helps!
Pretty sure i'm wrong on this one but I can't figure it out either.
Sorry if I wasted your time.
Angela must purchase 29.7 square yards of carpeting.
How to Convert Square Feet to Square yards?Multiply the area by the conversion ratio to convert a square foot measurement to a square yard measurement. Because one square foot equals 0.11 square yards, you may use the following easy formula to convert:
square inches = square feet × 0.11
The area in square inches is equal to the square feet multiplied by 0.11.
The dimensions of her living room are 15 feet by 18 feet.
The area in square feet is :
15 × 18 = 270 sq ft
Now, the area in square yards is :
270 × 0.11 = 29.7 sq yds
Thus, she must purchase 29.7 square yards of carpeting.

The width of the playhouse is 22 centimeters and the height is 10 centimeters. Not drawn to scale The yard space is large enough to have a playhouse that has a width of 3.5 meters. If Parker wants to keep the playhouse in proportion to the model, what cross multiplication of the proportion should he use to find the height?

Rae was estimating the difference between two positive numbers x and y (where x > y). First she rounded x up by a small amount. Then she rounded y down by the same amount. Finally, she subtracted the rounded numbers.
Which of the following statements is correct?
Question options:
Her estimate is larger than x − y.
Her estimate is smaller than x − y.
Her estimate equals x − y.
Her estimate equals y − x.
Her estimate is 0.
Answer: Her estimate is larger than x-y
Step-by-step explanation:
Which statement is false? A All whole numbers are integers. B All integers greater than 0 are whole numbers. C No real numbers are irrational numbers. D No integers are irrational numbers.
It is false that C. No real numbers are irrational numbers
Real numbers include both irrational and rational numbers so it is not true that a real number cannot be a rational number.
The other options are wrong because:
All whole numbers are indeed integers because integers are numbers that do not have to be written as fractions which makes them whole. All integers greater than 0 are whole numbers because they do not need to be written as fractions. Because integers are whole numbers, they cannot be irrational numbers which are numbers that go on forever e.g. π. Integers are whole which means that they can be completed.Conclusively speaking therefore, the only false statement here is that no real numbers are irrational numbers.
