Answer:
X is 6.
Step-by-step explanation:
What we know:
There's a ratio between 8 and 12, which simplifies to 2/3.
So, to find what x is, just multiply 2/3 times 9, to get 6 as x.
Answer:
259/30 or 8 19/30 depending on what format your teacher wants the answer
Step-by-step explanation:
First we can turn both mixed fractions into improper fractions and to do that we multiply the whole number by the denominator and that add that to the top number. So for 3 4/5 we would multiply 3 and 5 and than add 4 getting us to 19/5 doing the same to 4 5/6 gets us to 29/6. Now in order to add fractions we need to get a common denominator. The least common multiple of 5 and 6 is 30 so we will multiply each fraction by whatever number will give us 30 in the denomiator. for 19/5 that number is 6 so our new fraction is 114/30 and for 29/6 that number is 5 so our new number is 145/30. Now we just add the numerators and simplify. 114/30+145/30=259/30

<u>Answer:</u>
9. x = 12
10. x = 31
<u>Step-by-step explanation:</u>
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
<u>Check:</u>
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
<u>Check:</u>
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180

Answer:
figure please...... I cant see the figure
Answer:Learn to find the area of composite figures that contain circles and semi-circles. ... The area of the rectangle is 48 square inches. Next, recognize that ... Find the area of a figure that is made up of a square and a semi-circle.
Step-by-step explanation:I have made this reasoning: an eyelet consists of two semicircles and a rectangle (or two semirectangle), then a semicircle and a semirectangle ..But some irregular figures are made up of two or more standard geometric shapes. To find the ... We will break the figure into a rectangle and two semi-circles.
