Jack has g golf balls. The balls came in 8 packages. How many golf balls were in each package?

(3x²-2y²+5x)+(4x²+12y²-7x)

This is all about combining like terms.

(7x²+10y²-2x) is what I got.

(7x-10y-2x) is what Marcus got.

Marcus didn't add the squared symbol for 10y and he added a negative sign for 10y. He did -10y but it is +10y² because -2y²+12y²=10y². So, his problem is that Marcus didn't add right.

Hope this helps.

If it does, I would appreciate a brainliest rank.

Answer:

Volume = length * width * depth

= 3a^6 * a^2 * b^4

= 3a^(6+2)b^4

Step-by-step explanation:

The exponents 6 and 2 are added when the terms are multiplied

Swimming pool is generally build as a cuboid.

Volume of cuboid refers to the measurement of the space in the cuboid. It is the product of length, breadth and height of the cuboid.

Therefore the formula to calculate volume of cuboid will be:

                   [tex]\rm Volume\:of\:cuboid = \rm length\times breadth \times height[/tex]

The volume of the pool will be [tex]\rm 3a^8 b^4[/tex].

To reach the above answer, following calculations are required:

Given:

Dimensions of the pool:

[tex]\begin{aligned} \rm Length &= 3a^6\\\rm Breadth &= a^2\\\rm Height &= b^4\end[/tex]

Therefore, volume of pool will be as follows:

[tex]\begin{aligned} \rm Volume\:of\:cuboid &= \rm length\times breadth \times height\\&= 3a^6 \times a^2 \times b^4 \\&= 3a^{6+2}b^4\\&= 3a^8b^4 \end[/tex]

Volume of pool = [tex]\rm 3a^8b^4[/tex]

Answer: y-intercept = -12

Step-by-step explanation:

[tex]-3x = 60+5y[/tex]                         Add [tex]5y[/tex] on both side

[tex]-3x-60 = 5y[/tex]                          Subtract [tex]60[/tex] on both sides

[tex]-\frac{3}{5}x-12=y[/tex]                 Divide 5 on both sides

The y-intercept of the line -3x - 5y = 60 is equal to -12.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

Based on the information provided about this line, a linear equation in standard form that models it is given by;

-3x - 5y = 60

The solution to the linear equation -3x - 6 = 18 is x = - 8

The solution of the linear equation is calculated as follows;

The given linear equation;

-3x - 6 = 18

Move the constant term to the other side of the equation.

-3x - 6 + 6 = 18 + 6

-3x = 24

Divide both sides of the equation by the coefficient of x (-3) to isolate x.

(-3x) / (-3) = 24 / (-3)

x = -8

Thus, the solution to the linear equation -3x - 6 = 18 is x = - 8

Answer:

+22

Step-by-step explanation:

Given g(x) = -x^2 + 4x - 11, g(4) is -(4)^2 + 4(4) - 11, or just -11.

Then -2 times g(4) = -2(-11) = +22

6 times 4 is 24

4 times 6 is 24

24 divided by 6 is 4

1 1/3 is simplified to 4/3

multiply 4/3 * 2/3 =8/9

1 1/3 x 2/3 = 4/3 x 2/3 = 8/9 = 1 1/9

When you are multiplying fractions, you would multiply them like you would regular numbers. first, multiply the the numeraters together, then the denominaters together.

Example: 3/8 x 5/7 = 15/56

When you are multiplying whole fractions, you need to make them improper first before you multipy. Then you can multipy like normal.

Example: 2 3/4 x 6 2/4 = 11/4 x 26/4 = 286/16 (which can be simplified to 71 1/2

Given condition is- The bag contains individual pieces of Skittles, M&Ms, Life Savers and Sour Patch Kids.

Let the total number of candies in the bag be = x

Then, Skittles are [tex]\frac{1x}{2}[/tex]

Candies left = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]

M&Ms are = [tex]\frac{1x}{8}[/tex]

Now remaining candies are= [tex]\frac{3x}{8}[/tex]

Now Life savers are = [tex]\frac{9x}{32}[/tex]

Now adding all these 3 candies

[tex]\frac{x}{2}+ \frac{x}{8}+\frac{9x}{32}[/tex]

=[tex]\frac{29x}{32}[/tex]

Now the remaining candies sour patch will be =

[tex]x-\frac{29x}{32} =\frac{3x}{32}[/tex]

Hence, sour patch kids are [tex]\frac{3}{32}[/tex]

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.

Answer:

0.85(x - 350)

Step-by-step explanation:

Here "x" represents the pay before tax.

Take exempted amount = 350.

The taxable amount = x - 350.

The tax rate = 15% = 15/100 = 0.15

Take home pay after the tax deduction = Taxable amount - tax

= (x - 350) - 0.15(x - 350)

Now we have to simplify this.

= (x - 350)(1 - 0.15)

= (x - 350)(0.85)

The employee’s take-home pay after these deductions= $0.85(x - 350).

Final answer:

To multiply 14 by 25, you multiply each digit of 25 by 14 individually and then sum the results, yielding a product of 350.

Explanation:

The student has asked to multiply 14 by 25 and express the answer in simplest form. Multiplication is a basic arithmetic operation, and it is a straightforward process. To multiply 14 by 25, you can use the following steps:

Multiply the ones digit of the second number by the first number: 5 x 14 = 70.

Multiply the tens digit of the second number by the first number: 2 x 14 = 28. Remember that since this 2 represents 20 in the number 25, the result (28) will actually represent 280 when you include it in the final answer.

Add the results from steps 1 and 2: 70 + 280 = 350.

Thus, the product of 14 and 25 is 350.

The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Lets compare the dot plots of the two brands.

In Brand A,

The number of candy pieces per bag ranges from 52 to 62, and the dots are relatively evenly spread out across this range.

In Brand B,

the number of candy pieces per bag ranges from 44 to 69, and the dots are more spread out, with a larger range of values.

As we observe the majority of the dots are clustered around 52, 55, 62, 65, and 67, indicating that these values are more common in Brand B than in Brand A.

Brand B has more dots in total than Brand A, suggesting that Brand B generally has more candy pieces per bag than Brand A..

Hence, the number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.

Answer:

15 5/9 °C

Step-by-step explanation:

Put 60 where F is in the equation and do the arithmetic.

... C = (5/9)(60 -32) = (5/9)(28) = 140/9

... C = (135 +5)/9 = 15 5/9

The question states that we are looking for the reciprocal of 8/19.

Recall what a reciprocal is. A reciprocal, when looking at a number, is what is multiplied with it for it to equal 0. It is commonly regarded as just the fraction flipped. (For example, the reciprocal of 1/2 would be 2, or 2/1. 2 * 1/2 = 1)

This goes back to the simplifying, when multiplying two fractions together.

If you were to multiply two fractions, say [tex]\frac{5}{4}[/tex] and [tex] \frac{4}{5}[/tex], you could look at the numerator of one and the denominator of another, and cancel them out. In this case, the numerator of one is 5, and the other is also 5. Cancelling those out makes both one. If you cancel out 4 and 4 too, you get 1/1 * 1/1, or just 1.

We could go on asking why these methods work forever. Why does cancelling out a numerator and a denominator of separate fractions work? (A simple explanation is when the separate fractions are multiplied together, you could divide both sides by the factor which was originally used to cancel out with, which is what was stated above but simpler.)

Since we know the reciprocal is just the flipped form of the fraction, we can simply flip 8/19 to get our answer.

8/19 flipped is 19/8, which is our answer.
