Find the difference 51/4 - 2 3/4

1 answer:

4 0

Difference means to minus

5 1/4 - 2 3/4 =

[since 1/4 cannot minus 3/4, we need to convert one of the 5 wholes into quarters: 5 1/4 = 4 5/4 ]

5 1/4 - 2 3/4
= 4 5/4 - 2 3/4
= 2 2/4
= 2 1/2

Juan is making t-shirts to sell at a concert.

o-na [289]

Answer:

7 shirts

Step-by-step explanation:

The function for producing shirts is

f($) = 50 + 7.5(x), where x is the number of shirt

The function for selling shirts is

f($) = 15(x)

For there to be a profit, he must make more money selling the shirts than he spent on making the shirts

Therefore, 15(x) > 50 + 7.5(x)

15x > 50 + 7.5x

15x - 7.5x > 50

7.5x > 50

x > 6.67 shirts

To make a profit, Juan must sell at least 7 shirts

I need help on solving these types of geometry problems! Teacher said the answer is 7 but I have to show work. Thank you!

The vertex where the two triangles touch forms a pair of vertical angles, so that the angles on opposites sides of the vertex are congruent. You're shown that two legs of both triangles are congruent. All this tells you that the two triangles are isosceles, and furthermore that they are similar because of the congruence of their "base" angles.

This means

$82^\circ=m\angle 2$
