6/7 (7/6)x=5 (6/7) what is the value of x?

Mathematics

Answer:

x is 30/7

Step-by-step explanation:

You want to isolate x.

First, solve 5 * 6/7. The answer is 30/7.

Next, divide both sides by 6/7. This will cancel out the 6/7 on the left . For the right, when dividing fractions, you must take the reciprocal of the second fraction and multiply by it. So instead of having 30/7 divided by 6/7, you will have 30/7 * 7/6. The answer is 210/45 which simplifies to 5.

Third, you want to divide both sides by 7/6. Again the 7/6 on the left will be cancelled out. And you must do 5 * 6/7. In order to make the 5 look like a fraction to reduce confusion, you can set it over 1 (thus, you would do 5/1 * 6/7). The answer is 30/7.

You can plug it back into the equation to check.

Add '-1' to each side of the equation. 1 + -1 + 3d = 10 + -1 Combine like terms: 1 + -1 = 0 0 + 3d = 10 + -1 3d = 10 + -1                                                                      

Combine like terms: 10 + -1 = 9 3d = 9

Divide each side by '3'. d = 3 Simplifying

Help with finding proofs​
nadya68 [22]

Answer:

Statement: ∠XYZ = ∠ABC     Reasons: Below

Step-by-step explanation:

For two angles to be complementary means that the sum of the two angles is equivalent to 90°. When an angle has one of those little squares, that means the angle is a right angle, or a 90° angle. Also, since it's given that line segment AB and line segment BC are perpendicular, this means the two lines/line segments cross each other at a right angle, which also proves that line segment AB and BC have a 90° angle.

May anyone please help on these 2,Thank you so much,ill try to mark brainliest answer if i can
Neko [114]

Answer:

To the first question the answer would be > because you can change -3/4 to -9/12. Since these are negative numbers -5 is greater than -9.

The answer the second one would be B because I change all the fractions to decimals and 6/11 equals 0.54545454 and goes on and on So it was the greatest number (in decimal form). Also negaitve numbers are the least. :) Hope this helps

How do I solve this?
Snowcat [4.5K]

Answer:

Step-by-step explanation:

First, let's find the area of the triangle. The Area of a triangle can be modeled as

b x h x 1/2; base = 6 and the height equals 8. 6x8=48 then don't forget to divide by 2. 48/2= 24

To find the area of a half-circle, you first need to find the area of the whole circle. Whole circle area equation = r^2 times pi. The diameter is 8 and the radius is 1/2 times the diameter, therefore the radius = 4. 4^2= 16

16pi= approximately 50.24

50.24/2= 25.12

25.12 + 16 = 41.12

The area of the figure is approximately 41.12 ft^2

Hope this helps and please mark me brainliest, it really helps!

:)
