I don't see no choices for this question but I can tell u that greater than, less than, and equal to ALL SHARE THE SAME RESULT which is -1.

Here is my work for if 7t + 4 < 3t:

4 < 3t - 7t
4 < -4t
t < -1

Even if u do greater than, less than, or equal to it would all have the same answer, it would be t < -1, t > -1, and t = -1. Either way u do it, it will still have the same answer so in terms u can say answer is both or all of the above.

Answer:

x = 9.5y

Answer:

150Ft^2

Step-by-step explanation:

The area of a parallelogram is A=BH where B is base length and H is height. I'm not sure why there is information about a triangular base, maybe an illustration would help. But with the information provided, the base times height is equal to 150 Ft^2. Check out the Kahn Academy video for a better explanation

Professor shepherd weighed two pieces of metal for an experiment. the piece of iron weighed 7/12 of a pound and the piece of alu

Ira Lisetskai [31]

Answer:

The iron weighed 1/12 pound more than the aluminum.

Step-by-step explanation:

The weight of the aluminum is given as 1/2 pound. But that can also be written as 6/12 pound.

This is a subtraction problem (subtracting fractions...so also a common denominator problem)

In order to subtract fractions you have to get a common denominator.

7/12 - 1/2

= 7/12 - 6/12

= 1/12

The iron is 1/12 pound heavier than the aluminum.

I need to know how to simplify this equation

ArbitrLikvidat [17]

$\frac{ {3}^{x + 4} - {3}^{2x + 2} }{ {3}^{x - 2} \times {3}^{x + 4} } = \frac{x + 4 - 2x - 2}{(x - 2) \times (x + 4)} = \frac{ - x + 2}{ {x}^{2} + 4x - 2x - 8 } = \frac{ - x + 2}{ {x}^{2} + 2x - 8}$
i could be wrong, was kinda in a rush
