Answers

Answer 1

Answer: z=2

Step-by-step explanation:

2 x 2 = 4 + 3 = 7

Answer 2

Answer: Okay, the answer is z=2.

Step-by-step explanation: Step 1: Simplify the both sides of the equation: 2z+3=7.

Step. 2: Subtract 3 from the both sides: 2z+3−3=7–3.

Last but not least is step 3. Divide the both sides by 2: 2z/2=4/2. So you get z=2. I hoped my step-by-step explanation formula substitution is very helpful, please mark me as Brainliest, and have a happy holidays!!!!!!! :D

3/4X - 9 = 27 what does x equal?

Answers

Answer:X = 48

Step-by-step explanation:

Solve for  

x

by simplifying both sides of the equation, then isolating the variable.

The value of x in the equation given 3x/4 - 9 = 27, is 48.

Given is an equation, 3x/4 - 9 = 27, we need to find the value of x,

To find the value of x, we can solve the given equation step by step. Let's go through the process:

Start with the equation:

3x/4 - 9 = 27

To eliminate the fraction, we can multiply both sides of the equation by 4:

4 × (3x/4 - 9) = 4 × 27

Simplifying, we have:

3x - 36 = 108

Add 36 to both sides of the equation to isolate the variable:

3x - 36 + 36 = 108 + 36

Simplifying further:

3x = 144

Divide both sides of the equation by 3 to solve for x:

(3x) / 3 = 144 / 3

This gives us:

x = 48

Therefore, x equals 48 in the given equation: 3x/4 - 9 = 27.

Find the equation of a line that passes through the points (6,7) and (8,3).
Leave your answer in the form
y = mx + c

Answers

Answer:

y=-2x+19

Step-by-step explanation:

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:  m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

Now we have,

m= 3-7/8-6

m=-2. Since m=-2, the equation is y=-2x+b.

To find b, think about what your (x,y) points mean:

(6,7). When x of the line is 6, y of the line must be 7.

(8,3). When x of the line is 8, y of the line must be 3.

Substitute them to the equation  y=-2x+b.

You can use either (x,y) point you want..the answer will be the same:

(6,7). y=mx+b or 7=-2 × 6+b, or solving for b: b=7-(-2)(6). b=19.

(8,3). y=mx+b or 3=-2 × 8+b, or solving for b: b=3-(-2)(8). b=19.

So, the equation of the line that passes through the points

(6,7) and (8,3)  is  y=-2x+19.

Step 2: Convert to slope-intercept form

Subtract x on both sides:                    -y = 3 - xDivide both sides by -1:                        y = x - 3

Which option gives more earnings this​ weekend?

Answers

The Answer is: The hourly rate option of $112 is higher than the commission rate of $105.

Step-by-step explanation:

She will work 16 hours at $7.00 per hour:

16 * 7 = $112

Or she could take the 5% commission on $2,100:

2100 * .05 = $105.

The hourly rate is higher than the anticipated commission amount.

write in slope form 2y = 24 ​

Answers

Answer:

  y  = 12

Step-by-step explanation:

The equation of the expression is given as;

              2y  = 24

We are to write in slope form';

    In slope form, an equation is expressed as;

             y = mx + c

where y and x are the intercept

               m is the slope

                c is the intercept

Now to write 2y = 24 in intercept form, we have;

                 2y  = 24

  divide both sides by 2;

                y  = 12

What is the volume of a square pyramid that is 60 m on each side of its base and has a height of 100 m round to the nearest 10th

Answers

Answer:

Volume of square pyramid=120,000 m³

Step-by-step explanation:

We are given: Base of square pyramid = 60 m

Height of square pyramid = 100 m

We need to find Volume of square pyramid.

The formula used is: [tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h[/tex]

Where a is base and h is height of square pyramid

Putting values in formula and finding volume of square pyramid

[tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h\\Volume \ of \ square \ pyramid=\frac{1}{3}(60)^2(100)\\Volume \ of \ square \ pyramid=\frac{1}{3}(3600)(100)\\Volume \ of \ square \ pyramid=120,000\ m ^3[/tex]

So, Volume of square pyramid=120,000 m³
