Solve for x
-5(-2-5)-x-1=-12
Answer:
46
Step-by-step explanation:
-5(-2-5)-x-1=-12
-5(-7)-x-1=- 12
35 - x - 1 = -12
34 - x = -12
-x = -12 - (-34)
-x = - 46
x = 46
Answer:
[tex]x=46[/tex]
Step-by-step explanation:
[tex]-5\left(-2-5\right)-x-1=-12[/tex]
⟹ Subtract -2 and 5 = -7
[tex]5\left(-2-5\right)[/tex][tex]5\left(-7\right)[/tex]⟹ Remover parentheses:
[tex]5\times7[/tex][tex]-35[/tex][tex]-\left(-35\right)-x-1=-12[/tex]
⟹ Apply rule: [tex]-\left(-a\right)=a[/tex]
[tex]35-x-1=-12[/tex]
⟹ Combine like terms:
[tex]-x+35-1=-12[/tex][tex]\:35-1=34[/tex][tex]-x+34=-12[/tex]⟹ Subtract 34 from both sides:
[tex]-x+34-34=-12-34[/tex][tex]-x=-46[/tex]⟹ Divide both sides by -1:
[tex]\frac{-x}{-1}=\frac{-46}{-1}[/tex][tex]x=46[/tex]___________________

The surface area of the prism is 298 square feet. Find the value of x
Answer:
We can make an equation
2 * 7x + 2 * 4x + 2 * 4 * 7 = 298
14x + 8x + 56 = 298
22x = 298 - 56
22x = 242
x = 242/22
x = 11
If the surface area of the prism is 298 square feet, the value of x is 11 feet.
To find the value of x, we need to use the formula for the surface area of a rectangular prism:
Surface Area (SA) = 2lw + 2lh + 2wh,
where l is the length, w is the width, and h is the height of the prism.
Given that the length (l) is 7 ft and the width (w) is 4 ft, and the surface area (SA) is 298 square feet, we can set up the equation:
298 = 2(7)(x) + 2(7)(4) + 2(4)(x).
Now, simplify the equation:
298 = 14x + 56 + 8x.
Combine like terms:
298 = 22x + 56.
Now, isolate x by moving the constant term to the other side of the equation:
22x = 298 - 56,
22x = 242.
Finally, solve for x:
x = 242 / 22,
x = 11.
In summary, the height of the rectangular prism is 11 feet, and this value is obtained by using the surface area formula and solving the resulting equation.

Stem and leaf plots are best suited for data with a small number of place values such as 7, 30, or maybe even 340. The numbers in the data set are rather large and hard to demonstrate with a stem and leaf plot. Therefore, it probably isn't your best option. Hope this helps!
Answer:
A stem and leaf plot shouldn't be used because the numbers are more than two digits long. These numbers are more varied, so it isn't correct for a stem and leaf plot. The stem is usually the tens digit, and the leaf is the ones digit. When you have four digits, it would get infinite times more hard and complicated. Hope that helped!

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
Step-by-step explanation:
A = P(1 + r/n)^nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period

Which best describes the error in finding the percent increase from 18 to 26? The denominator should be 18, which is the original amount. The numerator should be 18, which is the original amount. The numerator should be 26, which is the new amount. The denominator should be 18, which is the new amount. The expression was simplified incorrectly. Question 2 Correct the error. Round your answer to the nearest whole number. The percent increase from 18 to 26 is about %.
Answer:
The percentage increase is 44.44%
What best describes the error is that the denominator should be 18 which is the original amount
Step-by-step explanation:
Here, we are to calculate the percentage increase from 18 to 26
Mathematically, we can calculate this with the following formula;
(New value - old value)/old value * 100%
Where the new value is 26 and the old value is 18. Plugging these values, we have;
(26-18)/18 * 100%
8/18 * 100% = 44.44% increase
The error in finding the percent increase from 18 to 26 is, The numerator should be 18, which is the original amount.
The percentage increase from 18 to 26 is about 44.4%.
We have to give that,
To find the percent increase from 18 to 26.
Now, The process to find a percent increase from 18 to 26 is,
(26 - 18) / 18 x 100%
= 8/18 x 100%
= 800/18%
= 44.4%

Answer: 33/4 miles per hour
Step-by-step explanation:
Hi, to answer this question we simple have to divide the distance travelled by the bike (2 3/4) by the time spent (1/3)
Speed rate = distance /time
Replacing with the values given:
S = 2 3/4 ÷ 1/3 = (2x4+3)/4 ÷1/3 =11/4 ÷1/3= 33/4 miles per hour

Mr. Schultz needs $200 to buy some new Jordan shoes. He was given $75 for his birthday. Which equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes? *
x + 75 = 200
75x = 200
200x = 75
x - 75 = 200
Answer:
The equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes is 75+x=200
Step-by-step explanation:
Mr. Schultz was given amount on his birthday = $75
We are given that Mr. Schultz needs $200 to buy some new Jordan shoes.
Let x be the amount of money Mr. Schultz needs to save to buy the shoes
So, Total Amount saved = 75+x
Total cost of shoes = $200
So, 75+x=200
So, The required equation is 75+x=200
So, Option A is true
Hence The equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes is 75+x=200

What is the volume of a circle
Answer:
volume = 4/3 × pi × r^3
Step-by-step explanation:
Answer:
Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.
Circumference = 2 • π • radius = π • diameter
Circle Area = π • r² = ¼ • π • d²
The circumference of a circle is directly proportional to its radius. The ratio between a circle's circumference and its diameter is pi, a constant that equals approximately 3.142. The circle's diameter, in turn equals twice the radius. A regular solid that has a circle as a face is called a cylinder. Like all geometric prisms, a cylinder's volume is the product of its cross-sectional area and its length. The cross-sectional area is the area of its circle, and you can calculate it from the circle's radius. Multiply the circle's radius by 2 to calculate its diameter. For instance, if the radius equals 6 inches, compute as follows to determine the diameter: 6 x 2 = 12 inches. Multiply the diameter by pi to get the circle's circumference: 12 x 3.142 = approximately 37.7 inches. Find the square of the radius: 6 x 6 = 36 square inches. Multiply the answer determined in Step 3 by pi to get the circle's area: 36 x pi = 113 square inches. Multiply the circle's area by the cylinder's length to obtain the volume. If the length is, for instance, 10 inches, then compute as follows: 113 x 10 = 1,130 cubic inches.
