Take 50 and divide it by 2, that will give you 25. Ming will have to play 25 hours of gaming time.

Your equation would be y, being 500, = 200 + 20(x), with xbeing hours.

500=200+20x
subtract 200 from both sides
300=20x
divide each side by 20
x=15 He would have to spend 15 hours to get 500 points.

A square has side length (x+5) units. What is it’s area
daser333 [38]

The area of square is x^{2}+10 x+25 square units

<h3><u>Solution:</u></h3>

Given that square has side length (x+5) units

To find: area of square

<em><u>The area of square is given as:</u></em>

\text {Area of square }=\mathrm{a}^{2}

Where "a" is the length of side

From question, length of each side "a" = x + 5 units

Substituting the value in above formula,

\text {Area of square }=(x+5)^{2}

{\text {Expanding }(x+5)^{2} \text { using the algebraic identity: }} \\\\ {(a+b)^{2}=a^{2}+2 a b+b^{2}}\end{array}

\begin{array}{l}{\text {Area of square }=x^{2}+2(x)(5)+5^{2}} \\\\ {\text {Area of square }=x^{2}+10 x+25}\end{array}

Thus the area of square is x^{2}+10 x+25 square units

NUMBER 27 please!!!!!!!
Artist 52 [7]
The inequality can be:
150x \leqslant 3000
Now you divide both sides by 150 to get the #of boxes.

3000 \div 150
Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20

ANSWER E and F PLEASE!!!!!! ASAP!!!
Novosadov [1.4K]

Answer:

And

H = 12

Step-by-step explanation:

3k = 9

k = 9/3

k = 3.

3k =k + 3t

subtitute value of k

3×3=3+3t

9-3=3t

6/3=t

t=2.

2k + h =18

2×3+h=18

h=18-6

h=12...
