Answer:

angle four equals angle 7 because they are alternate angles in a way.

Step-by-step explanation:

First if you go diagonally up from angle 4, you get angle 5. Then you go diagonally down. That angle isn't marked so I'll call it Z. But you could do it a faster way. You see, you could replace angle 4 with angle Z and vice versa. Then angle Z is the alternate angle of angle 7. One rule you should remember:

Alternate angles are equal.

Does this help? If it doesn't make sense let me know. (When I was learning this, it didn't make sense either)

Use the Formula d=r•t ( d= traveled is equal to the rate (r) of the speed times the time (t) it takes to travel that distance)

Ms. Handler drove at a rate of 75 km per hour. you do this by dividing the distance (225 km) by the time (3 hours) to get the average km traveled per hour

Answer:

$7$

Step-by-step explanation:

$3x+12x+12=7\\15x+12=7\\15x=-5\\x=\frac{1}{3}$

____

$3(\frac{1}{3} )+4y=7\\1+4y=7\\4y=6\\y=1.5$

$3(\frac{1}{3}) +4(1.5)=7$

maria brought a blouse on sale for 20% off. the sale price was $21.76. what was the original price? round to the nearest hundred

Degger [83]

Answer: $27.20

Step-by-step explanation:

She bought a blouse for 20% off so it means that she paid 80% of the original price.We can then set up the equation

80% of x = 21.76 where x is the original price so solve for x

0.8x = 21.76

x = 27.20

Which means the original price is $27.20

A game room has a floor that is 100 feet by 30 feet. A scale drawing of the floor on grid paper uses a scale of 3 units:5 feet.

Ghella [55]

3 units/ 5 feet = 60 units/ 100 feet
3 units/ 5 feet = 18 units/ 30 feet

The dimensions of the scale drawing are 60 units by 18 units.

Hope this helps!

If BD and EG are parallel lines and mBCF = 50°, what is mEFH?<br> Look at this diagram:

Burka [1]

It’s hard to tell due to no labels, but these are your angles due to the equal angles theorem and a few other theorems. Hopefully with this image you can hopefully find your answer. You may need to add angles together depending on what you are looking for. And possible even figure out what angle measure would make a (180 degree) triangle.
Hope this helped
