Answer:

3/12 simplified to 1/4

Step-by-step explanation:

When two fractions in an equation have the same denominator, you can easily subtract/add the numerator, so:

9 - 6 = 3

3/12

If you need to simplify your answer, your answer is 1/4

When simplifying this fraction, three is a multiple of 12 and 3 (called the common factor)

3 divided by 3 is 1

12 divided by 3 is 4.

V = 1/3Bh
B = 1/2(b1 + b2)t

V = 1/3[1/2(b1 + b2)t] * h
h = 24
b1 = 13
b2 = 29
t = ?
V = 2856

Substitute:
2856 = 1/3[1/2(13 + 29)t](24)
2856 = 1/6(42)(24)t
2856 = 7(24)t
2856 = 168t
t = 2856/168 = 17 in height of the trapeziod

Answer:

Step-by-step explanation:

In A, it says that 9s +7c can be lower or equal to 160. This is wrong.

In C, it says that 9s +7c can only be higher than 160, when the question says at least, which means it can also be equal to 160, making it wrong.

In D, it says that 9s +7c can be lower or equal to 20. This is wrong.

Through elimination, only B can be right.

-1 2/3 / (-2 1/5)<br> solve this for me please &&' thank you

dangina [55]

Start by putting into improper fractions.
- 1 2/3 = - 5/3
- 2 1/5 = - 11/5

Now stack the fractions like this.

$\frac{ \frac{-5}{3} }{ \frac{-11}{5} }$

Here's the key part (or one of them). Cancel the minus signs. Since there are 2 of them they become a plus.

$\frac{ \frac{5}{3} } { \frac{11}{5} }$

Now invert the 11/5. That means turn it upside down. Put the 5 in the numerator and 11 in the denominator. Multiply by it by the top fraction.

$\frac{5}{3} * \frac{5}{11}$

When you do this, you just multiply top by top and bottom by bottom
