Answer:

a=16

Step-by-step explanation:

We want to take the 6 on the left side of the equal sign and do the equation in the reverse.

First since we are adding 2, we want to substract 2 away from 6.

6-2 = 4

Then, since we are dividing by 4, we want to multiply by 4.

4*4 = 16

We can check this to make sure it's correct by replacing a with 16:

16/4 = 4

4+2 = 6

8x+5y=24 y=-4x Solve for y and x

Cloud [144]

Answer:

x= -2 and y= 8

Step-by-step explanation:

8x+5y=24-------A

y=-4x---------B

Putting the value of y from B in A

8x+5(-4x)=24

8x +(-20x)= 24

8x-20x=24

-12x=24

x= -24/12

x=-2--------C y =-4(-2)=8

You are baking brownies for your class. There are 28 total students in your class and you have baked 23 brownies. Right and solv

slavikrds [6]

Answer:

$x = 33$

Step-by-step explanation:

Given

$Students = 28$

$Brownies = 23$

$Brownies = 2\ per\ student$

Required

Determine the number of brownies left

If:

$Brownies = 2\ per\ student$

and there are 28 students

Then:

$Total\ Brownies = 2 * 28$

$Total\ Brownies = 56$

To determine the number of brownies left, we have:

$Total\ Brownies = Brownies\ Made + Brownies\ Left$

$56 = 23 + x$

Reorder

$x + 23 = 56$

Collect Like Terms

$x = 56 - 23$

$x = 33$

Hence, there are 33 brownies left
