A=-10 all you do to find a is simply add 2 to both sides of the equal sign

Answer:

a= -10

Step-by-step explanation:

To do this you would need to isolate a, or make a stand alone on its side of the equation

a-2=-12 Original equation

a-2+2 = -12+2 Isolating the variable(adding the 2 will cancel the -2 on the left side of the equation)

a= -12+2 Simplification

a= -10 The answer!!!

I hope this helps!!!

|13x-4|+12 < 56 Anybody know this cuz I do

Ronch [10]

Answer:

$\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)$

Step-by-step explanation:

Inequalities with Absolute Value

We must recall the following rule:

$\text{If }|M|0$

Then:

$-N$

We have the following inequality:

$|13x-4|+12 < 56$

Subtracting 12:

$|13x-4|< 56-12$

$|13x-4|< 44$

Applying the rule:

$-44$

Adding 4:

$-44+4$

Operating:

$-40$

Dividing by 13:

$\displaystyle -\frac{40}{13}$

The solution expressed in interval form is:

$\boxed{\displaystyle x\in \left(-\frac{40}{13},\frac{48}{13}\right)}$

Which division problem does the diagram below best illustrate? A diagram with 8 ovals containing 4 squares each. 16 divided by 4

Tems11 [23]

Answer: 32 divided by 4 = 8

Step-by-step explanation:

If the diagram is 8 ovals with 4 squares each, and we know that this is a division, then we have that an unknown number X is such that:

X/4 = 8

this is because we know that the division is by 4 (the number of squares in each oval) and the solution of the division is the number of ovals.

Then we can solve the equation for X.

X/4 = 8

We multiply each side of the equality by 4

X = 4*8 = 32

Then the diagram represents the division:

32/4 = 8 or " 32 divided by 4 = 8"

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Marrrta [24]

Answer:

no solution

Step-by-step explanation:

12x − 18y = 27

4x − 6y = 10

Multiply the second equation by -3 so we can eliminate x

-3(4x − 6y) = 10*-3

-12x +18y = -30

Add the first equation to this new equation

12x − 18y = 27

-12x +18y = -30

------------------------

0 = -3

This is not a true equation, so there is no solution
