Simplify both sides of the equation

2-(3x-4)=2x-9

2+-1(3x-4)=2x-9

Distribute the negative sign

2+-1(3x)+(-1)(-4)=2x-9

2+-3x+4=2x-9

2+-3x+4=2x+-9

Combine like terms

(-3x)+(2+4)=2x-9

-3x+6=2x-9

Subtract 2x from both sides

-3x+6-2x=2x-9-2x

-5x+6=-9

Subtract 6 from both sides

-5x+6-6=-9-6

-5x=-15

Divide both sides by -5

-5x/5=-15/-5

x=3


I hope that's help !

First put the -1 into the 3x and -4, so it looks like 2-3x+4=2x-9, then combine 2 and 4, (-3x+6=2x-9), then subtract 2x from both sides (-5x+6=-9) then subtract 6 to both sides so -5x=-15, then divide by 5 so x=3 hope this helps!! sorry i messed up the first time

The sum of two numbers is 85. twice one number plus four times the other is 218. find the numbers
Nina [5.8K]
X + y = 85
2x + 4y = 218
x = 85 - y 
<span>2(85 - y) + 4y = 218 </span>
<span>170 - 2y + 4y = 218 </span>
<span>170 + 2y = 218 </span>
<span>2y = 48 </span>
<span>y = 24 </span>
<span>x = 61</span>

What is the GCF of 48m5n and 81m2n2?
Lady bird [3.3K]
To find the GCF of the two terms, continuous division must be done.
What can be used to divide both terms such that there is not a remainder?
Start small, let's take 2. It could be a GCF.
Move up higher, say 3. Yes, it can be a GCF.
To see if there might be a greater common factor, divide the constants by 3.
48/3 = 16
81/3 = 27
Upon inspection and contemplation, there is no more common factor between 16 and 27. So, 3 is the GCF.

Moving on, when it comes to variables. The variable with the least exponents is easily the GCF. For the variable m, the GCF is m2 and for n, the GCF is n.

Combining the three, we have the overall GCF = 3m2n

Which of the following are not congruence theorems for right triangles? Check all that apply.
Lera25 [3.4K]

Answer:

c) HH E)AA

Step-by-step explanation:

Two right angles can be proved congruent by LA,LL,HA,HL properties.

HH and AA are not congruence property.

Two triangles can be proved similar by AA property. All congruent triangles are similar but all similar triangles are not similar.Hence right triangles can not be proved congruent by AA property.

Among the options given Option C and E are not congruence property.
