0.5x-8=12
Answer:
x = 40
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
So first you would do 12+8=20
Then you would do 20÷0.5=40
Now you want to check your answer
0.5x40=20 and 20-8=12
So x=40

The perimeter of the rectangle below is 42 inches. Find the value of X.
Please help
Answer:
x = 4
Step-by-step explanation:
42 = 5x + 5x + ( x - 3 ) + ( x - 3 )
42 = 12x - 6
48 = 12x
x = 4
Perimeter is the length around the rectangle (or any other shape). For rectangles, it's found by adding the side lengths. In this case, it required algebra to solve for x.
Answer:
x = 4
Step-by-step explanation:
The opposite sides of a rectangle are congruent.
The perimeter is the sum of the 4 sides, thus
2(5x) + 2(x - 3) = 42 ← distribute parenthesis and simplify left side
10x + 2x - 6 = 42
12x - 6 = 42 ( add 6 to both sides )
12x = 48 ( divide both sides by 12 )
x = 4

find the buying price when 5% sales tax is added on the purchase of 5kg of wheat at 20 per kg
Answer:
$300
Step-by-step explanation:
5% of x + 5 kg = 20
0.05 * x + 5 = 20
0.05x + 5 = 20
0.05x = 20 - 5
0.05x = 15
x = 15 / 0.05
x = $300
Yoko needs 300 copies of her resume printed. Dakota Printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies. If the number of sets of 100 resumes is represented by r, express the cost of the resumes c(r) algebraically as a piecewise function How much will 300 copies cost including a sales tax of 4 1/2%? Round to the nearest cent.
Answer:
29.79 should be the answer
Step-by-step explanation:
200 copies 19.50 + 9.00 for 100 copies = 28.50 + 4% = 29.79
The cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2 and =$29.78 is the cost of 300 copies including a sales tax of 4 1/2
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Dakota Printing charges 19.50$ for the first 200 copies and 9$ for every 100 additional copies.
Let r be the number of sets of 100 resumes.
c(r)=$19.5 when r represent an integer and is less than 2
c(r)=$19.5+(r-2) ($9) (1+0.045)
c(r)=$19.5+(r-2) ($9) (1.045) when r represent an integer and is greater than 2
the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2
c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2
Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)
=$28.5+$28.5(0.045)
=$28.50+$1.28
=$29.78
Hence, the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2 and =$29.78 is the cost of 300 copies including a sales tax of 4 1/2

5 x 6 = 30
6 x 6 = 36
8 x 6 = 48
Answer:
8
Step-by-step explanation:
The answer is 8 because the scale factor is 6 so if you divide the side that is corresponding to x (in this case 48) you would divide it by 6 because 6 is the scale factor. Hopefully I make sense...

450 meals served at 75 campus cafeteria 98 had less than 10 grams of fat but not less than 350 calories;110 had less than 350 calories but not less than 10 grams of fat
Incomplete question. The remaining question read;
What percentage of meals had less than 10 grams of fat? Round your answer to the nearest tenth of a percent.
Answer:
21.7%
Step-by-step explanation:
Remember, we are told that 98 out of the 450 meals served at 75 cafeterias had less than 10 grams of fat.
To calculate the percentage, we divide 98 by 450 and then multiply by 100:
[tex]\frac{98}{450}*100=[/tex] 21.7% approximately to the nearest tenth of a percent.

A summer biathalon-style race requires running a certain distance, and then biking a distance 2 miles more than the length of the run. One athlete has a running speed of 6 miles per hour, and a biking speed of 10 miles per hour, and completes the event in 90 minutes. How long, in miles, is each segment of the race
Answer:
The run is 4.875 miles long, while, the bike is 6.875 miles long.
Step-by-step explanation:
Let d = running distance and d' = biking distance.
Given that d' = d + 2 and v = running speed = 6 mph and v' = biking speed = 10 mph.
Since time, t = distance/speed, running time, t = running distance/running speed = d/6 and biking time, t' = biking distance/biking time = d'/10 = (d + 2)/10.
Since the total time, t" = 90 minutes = 1.5 hours,
t + t' = t"
So, d/6 + (d + 2)/10 = 1.5
multiplying through by the L.C.M, 30, we have
30 × d/6 + 30 ×(d + 2)/10 = 30 × 1.5
5d + 3(d + 2) = 45
expanding the brackets, we have
5d + 3d + 6 = 45
collecting like terms, we have
8d = 45 - 6
8d = 39
d = 39/8
d = 4.875 miles
d' = d + 2 = 4.875 + 2 = 6.875 miles
So, the run is 4.875 miles long, while, the bike is 6.875 miles long.
Help! Find the value of X. Thank you. (:
Answer:
x = 4
Step-by-step explanation:
The smaller triangle is an equilateral triangle, so all sides and angles are the same. We know that one side is labeled as 5, so all sides of that little triangle are 5.
The bigger triangle is an isosceles triangle because those two angles are marked as congruent. So, line JM and line KM are congruent as well.
The little triangle and the big triangle share side KM, so KM is equal to 5.
If JM is equal to KM and KM is equal to 5, JM is also five. That means:
x + 1 = 5
Subtract 1 from each side.
x = 4
And there we go.

What is the area of the real object that the scale drawing models?
Scale factor: 1:5
Area =
12 square cm
Scale drawing
Object
Answer:
60
Step-by-step explanation:
12 x 5 = 60
The area of the real object that the scale drawing models will be 300 square cm. Thus, the correct answer is option (A).
Given:
For Object
Scale factor: 1:5
For Scale drawing
Area = 12 square cm
The scale factor of 1:5 means that every unit on the scale drawing represents 5 units in the real object.
Since area is a two-dimensional measurement, the scale factor for area will be the square of the linear scale factor.
Here, the linear scale factor is 1:5, which means that each unit on the scale drawing represents 5 units in the real object.
Therefore, the area scale factor will be (1:5)² = 1:25.
If the area of the scale drawing is 12 square cm, then the area of the real object that the scale drawing models will be 12 × 25 = 300 square cm.
Therefore, the correct answer is:
A. 300 square cm.
