Write y = 4/3 * x - 2/3 in standard form Helpplppppp

Mathematics
1 answer:
raketka [301]3 years ago
3 0

Answer:

4x - 3y = 2

Step-by-step explanation:

First, let's review what "standard form" signifies:  Ax + By = C.

Starting with y = 4/3 * x - 2/3, multiply all three terms by 3 to eliminate the fractions:

3y = 4x - 2

Next, subtract 3y from both sides:

0 = 4x - 3y - 2.

It would be nice (tho' not essential) to have the coefficient of x positive.  That is why I've left 4x on the right side and subtracted 3y from both sides.

finally, add 2 to both sides, obtaining 4x - 3y = 2.  This is the equation in standard form.

Solve for x: 2x + (8x - 10) = 180
hram777 [196]

Answer: x=19

Step-by-step explanation: 2x+8x-10=180

Step 1: Simplify

2x+8x-10=180

2x+8x+-10=180

(2x+8x)+(-10)=180(combine like terms)

10x+-10=180

10x-10=180

Step 2: Add 10 to both sides

10x-10+10=180+10

10x=190

Step 3: Divide both sides by 10

10x/10=190/10

x=19

Greta currently works 45 hours per week and earns a weekly salary of $729. She
marissa [1.9K]

Answer:

Greta will be earning 3.6/h more at her new job.

Step-by-step explanation:

To find the difference subract Greta‘s salary from her current job from Greta’s salary from her future job.

To find Greta’s salary (numerator) at her future job divide her current weekly salary ($729) by 45h then multiply that answer (16.2) by the increase in salary 10% or 1.1. You should end up with $17.82- this is your numerator. To find the denominator divide her current hours (45h) by 45 then multiply that answer (1) by 0.9 which is the 10% decrease in hours. Now you have a fraction ($17.82/0.9) then multiply that fraction by 1.1/1.1 to get the denominator to 1 hour so you can subtract the fractions. You should end up with $19.8/h.

Now subtract Greta’s current salary ($16.2/h)- you just take the numbers from the first part before you increase or decrease- from her future salary ($19.8/h), you will end up with 3.6/h.

I was challenged to write this in a single equation:

[((($729\45h)x1.1)/((45h\45)x0.9))x1.1/1.1]-[($729\45h)/(45h\45)]

=$3.6/h

/ means a fraction bar

\ means division

Also I am just a student so please tell me if you find any mistakes I could fix or any suggestions to make this a better explanation, and if you have any questions ask away.
