Righty in equation in standard form using integers Y +1 equals 2/3 parentheses X +3 parentheses
Korolek [52]

Answer:

The standard for of the equation would be 2x + 3y = 3

Step-by-step explanation:

To start, we simply need to solve for the constant.

y + 1 = 2/3(x + 3)

y + 1 = 2/3x + 2

2/3x + y + 1 = 2

2/3x + y = 1

Now we need to multiply all the numbers by the largest denominator. This will make all the numbers integers. In this case, that number would be 3.

2x + 3y = 3

Solve for y<br> a. 4x + 5y = 25
AfilCa [17]

Answer:

y = -4/5x + 5

Step-by-step explanation:

In order to solve for y, we need to isolate the variable. First, let's subtract 4x on each side. After doing said step, we should now have this equation:

5y = -4x + 25

Next, we need to divide 5 on each side, giving us this new equation:

y = -4/5x + 5

There you go! Let me know if I did anything wrong ^-^

Answer:

9.11 x 10^-28

Step-by-step explanation:

if you divide 9.11 x 10^-28 by 1.67 x 10^-24 you get .000546

if you divide 1.67 x 10^-24 by 9.11 x 10^-28 you get 1,833

therefore, 1.67 x 10^-24 is 1833 times greater than the other value

Can someone help me with this please!~

Note that sum of triangle interior angles is 180. So,

(12x+12)+15+(3x+18)=180

15x+45=180

15x=135

x=9

Since A=12x+12=12.9+12=120

And C=3x+18=3.9+18=45
