Answer:
C. 12
Step-by-step explanation:
Corresponding sides are proportional. Sides with the same mark are the same length.
WX/XY = LM/MN = LM/KJ
WX/10 = 18/15
WX = 180/15 . . . . multiply by 10
WX = 12

A candy maker is mixing up some sugar syrup for use in making sweets. How much of 30% sugar syrup should she add to 12 liters of 20% sugar syrup to obtain a mixture that contains 26% sugar? Write your answer as a whole number or as a decimal rounded to the nearest tenth.
Answer:
She should add 18 liters of 30% sugar syrup
Step-by-step explanation:
Let the amount of sugar syrup be x
Mathematically;
30% of x liters + 20% of 12 liters = 26% of (x + 12)
So, we have
0.3x + 2.4 = 0.26x + 3.12
0.3x-0.26x = 3.12-2.4
0.04x = 0.72
x = 0.72/0.04
x = 18
Help please The actual distance between Apple Street and Pear Road is 8 miles. On a map, the distance is 3.5 inches. What proportion can you form to determine the scale on the map? 1 inch = ?
Answer:
1 in on the map = [tex]\frac{16}{7}\ miles[/tex] on the street
Step-by-step explanation:
Represent the actual distance as y and the map distance as x
So:
x = 3.5in when y = 8 miles
Required
Determine the proportion
The proportion of map measurement to actual measurement is:
[tex]x : y[/tex]
This gives:
[tex]3.5\ in : 8\ miles[/tex]
Divide by 3.5
[tex]\frac{3.5\ in}{3.5} : \frac{8\ miles}{3.5}[/tex]
[tex]1\ in: \frac{8\ miles}{3.5}[/tex]
Simplify the fraction
[tex]1\ in: \frac{8 * 2\ miles}{3.5*2}[/tex]
[tex]1\ in: \frac{16\ miles}{7}[/tex]
[tex]1\ in: \frac{16}{7}\ miles[/tex]
This means that:
1 in on the map = [tex]\frac{16}{7}\ miles[/tex] on the street
Convert the measurement.

How do I find a table that represents Y as a function of X
Answer:
C: x: 5, 2, 6, 4, 1, 3; y: 2, 2, 2, 2, 2, 2
Step-by-step explanation:
Things that can represent a function of x has to be able to be shown in the form of a function, such as "y =" or "f(x) =". I'm guessing you're learning about linear lines, so I'm going to talk about this with linear lines.
A linear line must be straight and for y to be represented as a function of x, it has to have a constant increase or decrease for every x. Here is how to identify non-function lines:
- If there are different y values for the same x value
- If the points in order do not create a straight line
- If the points in order do not have a repeating pattern
To identify a function, look for:
- Straight lines
- An actual written function (such as "y =" or "f(x) =")
- A pattern on a table
Now, the pattern you're going to be looking for on a linear table is an addition or subtraction one for every x. If the x values are in order, then for every 1 x, there should be a constant addition or subtraction to the y.
Here's an example of a table that represents y as a function of x:
- X: 1 2 3 4 5
- Y: 3 5 7 9 11
- Pattern: +2 y for every x with constant 1
- X: 3 1 5 4 7
- Y: 9 3 15 12 21
- Pattern: +3 y for every x with constant 0
Here's an example of a table that doesn't represent y as a function of x:
- X: 1 2 3 4 5
- Y: 2 5 8 2 4
- Pattern: None
- X: 3 1 5 1 7
- Y: 1 7 8 9 4
- Pattern: None

Louis earns a base monthly salary of $1,200 with 5% commission on sales. For a month with $25,000 in sales, what are Louis's total earnings?
Answer:
$2,450
Step-by-step explanation:
Since Louis earns 5% commission on sales, multiply the sales by 0.05:
25,000 × 0.05 = 1,250
Add that to the base salary:
1,250 + 1,200 = 2,450

a.y=5
b.y = -2
c. y = 10
d. y = 2
Help please !!
Answer:
easy the answer is d)y=2
Step-by-step explanation:
why because
3y−4=6−2y
Add 2y to both sides.
3y−4+2y=−2y+6+2y
5y−4=6
Add 4 to both sides.
5y−4+4=6+4
5y=10
Divide both sides by 5.
5y/5 = 10/5
y=2

Answer:
367.62 in³
Step-by-step explanation:
The volume of a sphere is V = (4/3)πr³.
Here, that volume of the whole sphere is V = (4/3)(3.14)(5.6 in)³, or
V = 735.25 in³
A 'hemisphere' is half a sphere. Thus, the volume of each hemisphere shown here is
735.25 in³
---------------- = 367.62 in³ This just about matches the first answer choice.

The volume of vegetable soup in a serving is proportional
to the mass of the serving. A 290 mL serving of vegetable
soup has a mass of 180 g. What is the mass of a 348 mL
serving of soup?
Answer:150
Step-by-step explanation:
The mass of 348mL serving soup is 216 grams
The serving is proportional; so, we have:
[tex]\mathbf{290mL = 180g}[/tex]
[tex]\mathbf{348mL = x}[/tex]
Where x represents the mass of 348mL serving soup.
Cross multiply.
So, we have:
[tex]\mathbf{x \times 290mL = 180g \times 348mL}[/tex]
Cancel out common units
[tex]\mathbf{x \times 290 = 180g \times 348}[/tex]
[tex]\mathbf{x \times 290 = 62640g}[/tex]
Divide both sides by 290
[tex]\mathbf{x = 216g}[/tex]
Hence, the mass of 348mL serving soup is 216 grams

-8 (c - 10) = - (c-3)
1 Remove parentheses.
-8(c-10)=−c+3
2 Regroup terms.
-8(c-10)=3−c
3 Expand.
-8c+80=3−c
4 Add 8c8c to both sides.
80=3−c+8c
5 Simplify 3-c+8c to 3+7c
80=33+7c
6 Subtract 33 from both sides.
80-3=7c
7 Simplify 80-3 to 77.
77=7c
8 Divide both sides by 7.
77/7 = c
9 Simplify 77/7 to 11.
11=c
10 Switch sides.
c=11
