Answer:

$x=12$

Step-by-step explanation:

We know that $\ell\parallel m$ .

Then by the properties of a transversal cutting a pair of parallel lines, we can write:

$(9x-4)+(5x+16)=180$

The property used here is the Consecutive Angles Property. The two consecutive angles are supplementary.

Now, we can solve for <em>x</em>. Rearrange:

$(9x+5x)+(-4+16)=180$

Combine like terms:

$14x+12=180$

Subtract 12 from both sides:

$14x=168$

Divide both sides by 14:

$x=12$

So, the value of <em>x</em> is 12.

The table shows the steps for solving the given inequality for x.

slavikrds [6]

Given inequality -3(4-6x) < x+5.

We have -3 in front of Parenthesis.

That represents multiplication of -3 and Parenthesis.

The multiplication of Parenthesis could be done by applying distributive property.

On distributing, we get

-12+18x < x+5

x is added on right side of the inequality. The reverse operation of addition is subtraction. So we need to subtract x from both sides, we get

-12+18x-x < x-x+5

-12+17x < 5

Now, we need to get rid -12 from left side.

So, we need to apply addition property of equality, we need to add 12 on both sides, we get

-12+12+18x < x+5+12

17x < 17

We need to get rid 17 from left side. So we need to apply division property of equality.

On dividing both sides by 17, we get

17x/17 < 17/17

x<1.

I have no idea how to do this someone helped me with this and got the right answer which is 11/17 but I got a totally different

Travka [436]

Answer:

Step-by-step explanation: The reason is is because when adding and subtracting integers, you flip the operation sign that will be used to solve the problem.So when you flip the sign of this equation, you subtract. So that's how your answer was 11/17. Also it is positive because the biggest number is positive so that is what the solution will be.

You are choosing between two health clubs. Club A offers membership for a fee of $12 plus a monthly fee of $28. Club B offers me

EleoNora [17]

A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.

B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.

how many months for the cost to be the same?

$\stackrel{A}{12+28m}=\stackrel{B}{20+26m}\implies 12+2m=20\implies 2m=8\implies m=\cfrac{8}{2}\implies m=4$

well, since the cost for both is the same, we can just get A's, knowing that B is the same

$12+28(4)\implies 12+112\implies 124$
