Solve for q.
3(q − 7) = 27
q =
Answer:
The answer is, q = 16.
Step-by-step explanation:
1) Divide both sides by 3.
[tex]q - 7 = \frac{27}{3} [/tex]
2) Simplify 27/3 to 9.
[tex]q - 7 = 9[/tex]
3) Add 7 to both sides.
[tex]q = 9 + 7[/tex]
4) Simplify 9 + 7 to 16.
[tex]q = 16[/tex]
Therefor, the answer is q = 16.
Answer:
q=16
Step-by-step explanation:
To solve this problem, you'll want to start by distributing the 3 to both q and -7, which will give you 3q-21=27. Then, you should add 21 to both sides, which will get the variable alone on one side of the equation. After that step, your equation should be 3q=48. Lastly, divide both sides by 3, which will give you the answer q=16!

What are the coordinates of the image D(0.5)(1, 2)?
Answer:
(0.5, 1)
Step-by-step explanation:
The coordinates of the image of the point D (0.5, 2 ) are 0.5 and 2.
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Given that:-
The image of point D ( 0.5 , 2 ) is given so the coordinates of the point will be 0.5 and 2.
Hence the coordinates of the image of the point D (0.5, 2 ) are 0.5 and 2.

Step-by-step explanation:
Five oranges weigh as much as two grapefruits. An oranges weighs 80 g. What is the weight of one grapefruit?
Answer: 200 grams.
Step-by-step explanation:
80 x 5 = 400
400 divided by 2 = 200.
We need to find how much 5 oranges weighs by multiplying 80 by 5.
80x5=400
So 5 oranges weighs 400 grams. We also need to find the weight of one grapefruit. Since 5 oranges, or 400 grams, weigh the same as 2 grapefruits, we need to divide 400 by 2.
400/2=200
So each grapefruit weighs 200 grams.

How do you decide where to shade an inequality whose boundary does not go through the origin?
Answer:
If it does not satisfy the inequality, shade the region which does not contain that point. All the points in the shaded region will satisfy the inequality. Note: The origin (0, 0) is usually the easiest point to test, provided it is not on the line.
Inequalities are used to represent unequal expressions.
The region to shade are the region that satisfy the inequality.
Take for instance the following inequality
[tex]\mathbf{y \ge 2x + 5}[/tex]
The above inequality represents greater than or equal to.
This means that, the regions that satisfy the inequality are the region on the line of [tex]\mathbf{y \ge 2x + 5}[/tex] and the areas above it.
If the inequality is less than, then the region below the line of the inequality will be shaded.

The population density of City A is 6000 people per square mile. City B is a dilation of City A with scale factor 1.5 . If City B has 3/5 of the population of City A, what is the population density of City B?
Answer:
[tex]1600\ \text{people per square mile}[/tex]
Step-by-step explanation:
Number of people per square mile in City A is 6000.
In terms of size City B is a dilation of City A with scale factor 1.5.
This means a length of 1 mile in city A would be 1.5 miles in city B.
So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]
City B has [tex]\dfrac{3}{5}[/tex] of the population of City A.
So the population density of City B would be
[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]
The population density of City B is [tex]1600\ \text{people per square mile}[/tex].
If a rectangle with length 6 cm and width 4 cm is enlarged by a scale factor of ½, then what is the perimeter of the new rectangle?
The perimeter of the new rectangle is 23cm
How to determine the perimeterFormula for perimeter is given by
Perimeter = 2(length + width)
Perimeter = 2( 6 + 4)
Perimeter = 2 × 10
Perimeter = 20cm
If the length and width are enlarged by 1/2, we have
Perimeter = 2( 6 + 4 +1/2)
Perimeter = 2( 10 + 0.5)
Perimeter = 2× 11. 5 = 23cm
Thus, the perimeter of the new rectangle is 23cm

Suppose it takes 2 1/2 h to drive from your house to the lake at 48 mi/h. How long will your return trip take at 40 mi/h?
Answer
The distance from the house to the lake is (2.5 hr)*(48 mi/hr) = 120 miles. The rerurn trip would take (120 mi)/(40 mi/hr) = 3 hours. Distance equals rate times time, so the distance to the lake is 2 1/2 hours times 48 miles per hour.
