one teacher want to give each student 4/5 of a slice of pizza, if the teacher has 4 slices of pizza, then how many students will

GuDViN [60]

Answer:

The answer is 5 students.

Step-by-step explanation:

This problem is a division problem.

To solve, divide 4 by 4/5.

There is a strategy for this- Keep, Change, Flip.

Keep the dividend like it is, which is 4 or 4/1.

Change the division to multiplication.

And flip the divisor- 4/5 to 5/4.

When you multiply, you should get 20/4.

Simplify by dividing 20 by 4.

20 divided by 4 is 5.

So the answer is 5 students

The length of the hypotenuse of a right triangle is 157 units. The length of one leg of the triangle is 132. Lara wrote the foll

ra1l [238]

It is incorrect because the length of the unknown side is the square root of 7,225.

If you use the pythagorean theorem and plug in the values,

a^2 + 132^2 = 157^2

a^2 + 17424 = 24649
-17424 -17424
_________________
a^2 = 7225

If you square root it, the final answer would be 85.

write an equations in slope-intercept form of the line that passes through the point(5,9) with slope 7

vovangra [49]

Answer:

$y=7x-26$

Step-by-step explanation:

1) Write it in the slope-intercept form of $y=mx+b$ , where m is the slope and b is the y-intercept.

$y=7x +c$

2) Substitute the given coordinates into $y=7x +b$ , and then solve for c.

$9=7(5) +b\\9=35+b\\9-35=b\\b= -26$

3) Substitute c into $y=7x +b$

$y=7x-26$

Therefore, the answer is $y=7x-26$ .

X=15 is this a function how do you do it

Alexxandr [17]

9514 1404 393

Answer:

Step-by-step explanation:

The graph of this equation on an x-y plane is a vertical line. The input value x=15 maps to an infinite number of outputs (y-values). For a relation to be a function, each input can only map to one output.

x = 15 is not a function
