Answer:

In decimals A= 7.25 , B = 6.75 , C=5.2 and D=6.1

Step-by-step explanation:

Given : Tom works part-time at a theme park.

Tom needs to complete his time sheet in decimals.

Consider the time sheet as shown below in image attached,

We need to calculate the value of A , B, C and D in decimals.

Since,  A , B, C and D denotes the total work Tom Jackson did on respective days.

Thus, A is the total hours Tom Jackson worked along with the  part-time hours he worked.

A= hour worked + fraction hour worked

A=7+\frac{1}{4}\\\\\\\text{Taking LCM , we get}\\\\\ A=\frac{28+1}{4}=\frac{29}{4}=7.25

Similarly for B, C and D

B= hour worked + fraction hour worked

B=6+\frac{3}{4}\\\\\\\text{Taking LCM , we get}\\\\\ B=\frac{24+30}{4}=\frac{27}{4}=6.75

C= hour worked + fraction hour worked

C=5+\frac{1}{5}\\\\\\\text{Taking LCM , we get}\\\\\ C=\frac{25+1}{5}=\frac{26}{5}=5.2

D = hour worked + fraction hour worked

D=6+\frac{1}{10}\\\\\\\text{Taking LCM , we get}\\\\\ D=\frac{60+1}{10}=\frac{61}{10}=6.1

Thus, In decimals A= 7.25 , B = 6.75 , C=5.2 and D=6.1

Solve for zzz. 42=-7(z-3)42=−7(z−3)
xxTIMURxx [149]

Answer:

False

Step-by-step explanation:

Well to solve for z we single it out, distribute, use the communicative property, and combine like terms.

42 = -7(z - 3)42 = -7(z - 3)

Distribute

42 = -7z + 21*42 = -7z + 21

42 = -7z + 882 = -7z + 21

-42 to both sides

-7z + 840 = -7z + 21

-21 to both sides

-7z + 819 = -7z

+7z to both sides

819 = 0

<em>Thus, </em>

<em>the given equation is false.</em>

<em>I hope this helps :)</em>

Answer:

D (0, 2)

General Formulas and Concepts:

<u>Algebra I</u>

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

y = 3/4x + 2

<u>Step 2: Break Function</u>

<em>Identify Parts</em>

Slope <em>m</em> = 3/4

y-intercept <em>b</em> = 2

Select the correct answer.

You use the FOIL method, and how you do this is -

(x - 7) (x + 8)

Multiply the first x by both numbers in the second factor. Which means, you multiply x by x and 8, the two in (x + 8).

With this, you get -
x^2 + 8x

Then do the same thing with -7.

-7x - 56

Then combine the two.
x^2 + 8x - 7x - 56

Combine like terms.

x^2 + x - 56

So now, 7 x 8 is 56
And -7 + 8 would be 1. And that is the value of “x” which is b in the form a^2x + bx + c.

Now with this, you take those two numbers and make the factors =
(x + 8) (x - 7)

Then you set these equal to 0.

x + 8 = 0

Subtract the 8 from both sides.

x = -8

————

x - 7 = 0

Add the 7 on both sides.

x = 7
