-7t-3t would be -4t
4 is less than or equal to -4t
Divide 4from -4
-1 is less than or equal to t

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.

Four students spent $9.40 on school lunch.at this rate,predict the amount 10 students would spend on the same school lunch

Tom [10]

You will need to know how much each lunch cost
so
9.40 ÷ 4 = 2.35
so each lunch cost 2.35 dollars

now we need to find out how much it will cost for 10 lunches

10 x 2.35 = 23.5

so for 10 lunches it will cost 23.5

|×|=× is the absolute value of x always, sometimes, or never x

il63 [147K]

Answer:

Sometimes

Step-by-step explanation:

I’ll give you an example so you can understand:

Let’s say x is 4. So plug 4 into the problem:

|4|=4 → This is a very true statement, where the absolute value of 4 is equal to 4.

Now, let’s say x is -7. So plug -7 into the problem:

|-7|=-7 → This is a false statement because it’s saying that the absolute value of -7 is -7 which is very untrue.

So |x|=x only works for positive numbers, but not negative numbers. Therefore, |x|=x is the absolute value of x sometimes.

Hope this helps and answers your question! :)

Quadrilateral ABCD is similiar to quadrilateral EFGH. The lengths of the three longest sides in quadrilateral ABCD are 24 feet,

MatroZZZ [7]

The two quadrilaterals are given similar .

In any similar figure sides are in proportion.The second largest side of quadrilateral ABCD is 16 ft .Let the second longest side of quadrilateral EFGH be x ft. These sides will be in proportion to each other .

The second shortest side of quadrilateral EFGH that is GF will be proportional to the third longest side of quadrilateral ABCD that is BC

We can form a proportion with the proportional sides:

$\frac{16}{x} =\frac{12}{18}$

To solve for x we cross multiply

12x=(16)(18)

12x=288

Dividing both sides by 12 we get

x=24.

The second longest side of quadrilateral EFGH is 24 ft.
