Question : If lines BG and CF are parallel, then OLF = OMG. Is this statement correct? Explain your answer.

Answers

Answer:

Yes this statement is correct.

Step-by-step explanation:

just mental math

The statement given that ∠OLF = ∠OMG is found to be; Correct from theorem of corresponding angles.

We are told that;

BC is parallel to CF

Now, we are told that;

∠OLF = ∠OMG

We can see that line DH is a transverse line that crosses the two parallel lines given as BG and CF

Now, according to theorem of corresponding angles, the angle's that are formed when two parallel lines are crossed by a transverse line are said to be equal because they correspond to one another.

In conclusion, it is true from corresponding angles that ∠OLF and ∠OMG are equal.

He probably won't get too suspicious if you get 100% on three quizzes when you regularly get A's in that class.  A ninety-something percent jump to a 100 is less than a 10-point increase.  

That being said, it's still best to learn the math so that you don't become dependent on using Brainly for every question.  Maybe only use it when you're having a lot of trouble with a particular problem or concept; but some of the explanations on here are actually really helpful in teaching things.

What is the answer Timothy curtain company is making curtains for a local hotel he wants each certain to be 48 inches long at the fabric store from Vegas sold by the foot and Timothy's certain company wants to make 45 curtains how many feet of fabric but you need 1 inch equals one12 foot

Answers

Answer:

180 feet

Step-by-step explanation:

The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.

But,

1 inch = 12 feet

So that,

48 inches = x feet

⇒ x = [tex]\frac{48}{12}[/tex]

      = 4

Thus,

48 inches = 4 feet

The number of feet of fabric needed for 45 curtains can be determined as:

45 x 4 feet = 180 feet

Therefore, 180 feet of fabric would be needed to make 45 curtains.

solve the literal equation 2y + 5x = 3x +8 for x
help please I'm on a timed test​

Answers

Step-by-step explanation:

Simplifying

5x = 3x + 8

Reorder the terms:

5x = 8 + 3x

Solving

5x = 8 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

5x + -3x = 8 + 3x + -3x

Combine like terms: 5x + -3x = 2x

2x = 8 + 3x + -3x

Combine like terms: 3x + -3x = 0

2x = 8 + 0

2x = 8

Divide each side by '2'.

x = 4

Simplifying

x = 4

Answer:

x = -y + 4

Step-by-step explanation:

2y + 5x = 3x + 8

2x + 2y = 8

2x = −2y + 8

x= −y + 4

It depends on how much the computer costs originally and the model of computer.

Step-by-step explanation:

Say the computer costs 151.98 USD with the tax added, then the computer would cost 148.00 USD without tax.  Or if the computer costs 162.79 USD with the tx added, then the computer would cost 160.00 USD without tax. It's the same for the rest but it also depends on the model of computer. (My calculations of adding 3 or 2 USD as the tax is just for example, i don't know how they calculate tax for computers)

151.98-148.00= 3.98$

4 Add 8c8c to both sides.

80=3−c+8c

5 Simplify 3-c+8c to 3+7c

80=33+7c

6 Subtract 33 from both sides.

80-3=7c

7 Simplify 80-3 to 77.

8 Divide both sides by 7.

77/7 = c

Step-by-step explanation:

To solve this, we first need to find 13% of $5,400.

5,400 x 0.13 = 702

Therefore, Nadia earned a total of $702 last week in commission.

Now, we need to calculate how much money she'll earn in a whole year. So, let's see how many weeks are in a year.

1 year = 52 weeks when rounded to the nearest whole number

702 x 52 = $36,504

Therefore, Nadia earned a total of $36,504 in commission in 2011.
