5 0

Answer:

s= 65

Step-by-step explanation:

The given quation s = 20h + 10

h= number of hours

Where h= 2.75 hours

If we substitute h into given model equation, we have

s = 20(2.75)+ 10

s=55 +10

s= 65

Hence, her score is 65

Write the sentence as an inequality.<br> 5 is no greater than 4 times a number minus 2.5.
garri49 [273]

Answer:

<em>5 ≤ 4x - 2.5</em>

Step-by-step explanation:

<u>Inequalities</u>

The expression "no greater than" can be better expressed as "less or equal than".

The expression 4 times a number, being x the unknown number can be written: 4x

Thus, the equivalent inequality of the sentence is:

5 ≤ 4x - 2.5

∠DEF and ∠FEG are supplementary. m∠DEF=(3x+5)°, and m∠FEG=(2x)°. What is the measure of ∠DEF?
Alex787 [66]

Answer:

DEF = 110

Step-by-step explanation:

Supplementary angles add to 180

3x+5  +2x = 180

Combine like terms

5x +5 = 180

Subtract 5 from each side

5x = 175

Divide each side by 5

5x/5 = 175/5

x =35

DEF = 3x+5

     = 3*35 +5

    = 105+5

   = 110

What is the midpoint of this segment??
Korvikt [17]

Answer:

A) 6,3

Why?

The midpoint, which is somewhat self-explanatory thanks to its name, is a point in the center of a line.

To answer this question properly, you need to analyze the line and assess the situation.

How did it go from x = 2 to x = 10? Let's see, if we count by two's across the line, you'll notice it makes more sense. So now we know that every square goes up by two. x = 6 is the exact center of the line.

I hope this wasn't confusing, it's tough to explain it!
