What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Cost of each calculator = $31.25
Cost of x calculators.
= 31.25x
Now,
The total cost of the calculators = $500.
The number of calculators bought.
= 500/31.25
= 16
Thus,
The cost of x calculators is 31.25x.
The number of calculators bought is 16.

To find the answer, we need to simplify the ratios:
4:6 = 2:3
6:9 = 2:3
9:12 = 3:4
We can now clearly see that Recipes 1 and 2 will taste the same, since they have the same OJ to PJ ratio.

The ratio of balls to tennis balls is 4:7 is a correct statement; however, we need to check the other questions for reliablity.
For every 6 basketballs, there are 10 dodge balls is a wrong statement because the number of basketballs is 12 and the number of dodge balls is 18 not 20. So, this answer is wrong.
None of the above is wrong because the first answer is correct so we can cross out c.
Now we know that A is the correct answer!
It is A, the ratio of soccer balls to tennis balls is 4:7.
Soccer Balls : 8
Tennis balls: 14
8 divided by 2 is 4 and 14 divided by 2 is 7.
4:7
B is not right because
Basketball: 12
Dodgeball: 18
"For every 6 basketballs, there are 10 dodge balls."
12 divided by 2 is 6
If it was 10 dodge balls for every 6, dodge balls would be 20 because there are 2 6s in a 12.
And it can't be C, none of the above because A is correct.
So yea it's A.

A cylinder has a volume of 1884cm^3. Find the volume of a cone with the same radius and height as the cylinder
Answer:
628
Step-by-step explanation:
The volume V of a cylinder whose radius is r and height is h is given as
V = πr²h
The volume of a cone v of a radius r and height h is also given as
v = 1/3 πr²h
As such , given that the cylinder has a volume of 1,884 cm ³, the volume of a cone with the same radius and height as the cylinder
= 1/3 * 1,884 cm ³
= 628 cm ³

A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.
Answer:
29.88 inches
Step-by-step explanation:
Equation of a line is given in the form
Where
m is the slope [rate of change, here, rate of decrease]
c is the y-intercept [at 1920, the snowfall]
From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24
Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:
y = mx + b
y = -0.24 x +48.6
To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:
y = -0.24(78) + 48.6 = 29.88 inches
Answer:
29.88 inches

$6 x 80 =480
Sandy had a total of $2,986 in sales before taxes. Sandy earns 10% commission on her sales, so
$2,986 x 0.1 = 298.60
is Sandy's earning on sales.
In total, Sandy earned

Step-by-step explanation:
y/6+6=-19
Subtract 6 from each side
y/6+6-6=-19-6
y/6 = -25
Multiply each side by 6
y/6 * 6 = -25*6
y = -150

Please help! Twenty points.
5 ( f + 4) = 4 ( f - 6)
f = -44
Hope this helps :)
Answer:
The answer is -44
Step-by-step explanation:
First, you use distributive property on each side.
5xf + 5x4 = 4xf-4x6
5f+20=4f-24
Then you subttract 5f to both sides of the equation.
5f+20=4f-24
-5f -5f
20=-1f-24
Next, you add 24 to both sides of the equation.
20=-1f-24
+24 +24
44=-1f
Finally, you divide -1f from each side of the equation.
44=-1f
/-1f /-1f
Your final answer should be -44=f
or f = -44
