hope this helps

Answer:

6

Step-by-step explanation:

Step 1:

2 ( j + 4 ) = 20        Equation

Step 2:

2j + 8 = 20     Multiply

Step 3:

2j = 12        Subtract 8 on both sides

Step 4:

j = 12 ÷ 2        Divide

Answer:

j = 6

Answer:

m=18+n

Step-by-step explanation:

m + -18 = n            simplify

-18 + m = n            record the terms

-18 + 18 + m = 18 + n             solve

Combine like terms: -18 + 18 = 0,   0 + m = 18 + n,     m = 18 + n

Final answer: m = 18 + n

Answer:

IDK but here's what I have found.....

Step-by-step explanation:

Simplifying

m + -18 = n

Reorder the terms:

-18 + m = n

Solving

-18 + m = n

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + m = 18 + n

Combine like terms: -18 + 18 = 0

0 + m = 18 + n

m = 18 + n

Simplifying

m = 18 + n

Answer:

7425

Step-by-step explanation:

First let's make the last two fractions improper.

-4  1/2 = -9/2    -2  1/5 = -11/5

Now we have to find the least common denominator.

[tex]\frac{5}{6} *\frac{-9}{2}*\frac{-11}{5}[/tex]

The least common denominator is 30 because all the denominators can be multiplied by something to get 30.

[tex](\frac{5}{5})*\frac{5}{6}* (\frac{15}{15})*\frac{-9}{2}* (\frac{6}{6})*\frac{-11}{5}[/tex] Simplify

[tex]\frac{25}{30}*\frac{-135}{30}*\frac{-66}{30}[/tex] simply

[tex]\frac{-3375}{30}*\frac{-66}{30}[/tex]

[tex]\frac{222750}{30}[/tex] simply

Answer:

60

Step-by-step explanation:

10 / 2 * ( 9 + 3 )

remember the order of operations: parenthesis first

10 / 2 * ( 9 + 3 )

10 / 2 * 12

now there is only multiplication and division, so it shouldn't matter which is done first, the answer will still be the same

10 / 2 * 12

Answer:

The expression to represent the total shipping costs for x package is 6x.

Tommy will pay $ 12 in shipping and handling for 2 packages.

Step-by-step explanation:

Given that the shipping and handling charge for 1 package = $ 6

So, by using the elementary method, the shipping and handling charge for x package is $ 6x.

Hence, the required expression to represent the total shipping costs for x package is 6x.

For 2 package, x=2

So, the shipping and handling charge for 2 package

=6x2

=12.

So, Tommy will pay $ 12 in shipping and handling for 2 packages.

Answer: c=2[tex]\pi[/tex]r

Step-by-step explanation: Circumference is 2 times pi times radius.

Given:

A quadratic function has a line of symmetry at x = –3.5 and a zero at –9.

To find:

The other zero.

Solution:

We know that, the line of symmetry divides the graph of quadratic function in two congruent parts. So, both zeroes are equidistant from the line of symmetry.

It means, line of symmetry passes through the mid point of both zeroes.

Let the other zero be x.

[tex]-3.5=\dfrac{(-9)+x}{2}[/tex]

Multiply both sides by 2.

[tex]-7=-9+x[/tex]

Add 9 on both sides.

[tex]-7+9=-9+x+9[/tex]

[tex]2=x[/tex]

Therefore, the other zero of the quadratic function is 2.

Answer: A=0, B=6, C=4.

The axis of symmetry is x = ½

The smaller zero is -2

The larger zero is 3

Step-by-step explanation: Correct in edge 2020, the format makes it hard to find answers online but I just did the assignment

U can use the cross multiplication to find out

5/8 = x/100

x=5/8 * 100

x= 62.5

Answer: 1.57 x 104

Step-by-step explanation: How to Convert a Number to Scientific Notation

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.

Count how many places you moved the decimal point. This number is b.

If you moved the decimal to the left b is positive.

If you moved the decimal to the right b is negative.

If you did not need to move the decimal b = 0.

Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."

Remove trailing 0's only if they were originally to the left of the decimal point.

Answer: These Lines are Parallel

Step-by-step explanation: For two lines to be parallel, they must have the same slope with different y-intercepts. Both of the lines above have a slope of 3 and differing y-intercepts of 4 and -5. Therefore, these lines must be parallel to one another.

Answer:

x=1

Step-by-step explanation:

subract 4.3 from both sides. add x to both sides. divide by 2.2 from both sides

The solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.

Given is an equation 1.2x + 4.3 = 2.1 - x, we need to solve for x,

To solve the equation 1.2x + 4.3 = 2.1 - x, we can follow these steps:

1. Combine like terms on both sides of the equation:

1.2x + x = 2.1 - 4.3

2. Simplify the equation:

2.2x = -2.2

3. Divide both sides of the equation by 2.2 to isolate x:

x = -2.2 / 2.2

4. Simplify the right side of the equation:

x = -1

Therefore, the solution to the equation 1.2x + 4.3 = 2.1 - x is x = -1.
