First you would find a common denominator. If 40 is the LCM then you would have to add playing games, instruction,warm-up, and cool-down. Then you will subtract the sum from the total class time and bam! You get your answer!
Answer: See explanation
Step-by-step explanation:
We are informed that we should write a equation that represents the expression "Ali writes the expression "half of the sum of $9 and a number.".
Let the number be represented by x. The first equation based on the information given will be:
= 1/2(9 + x)
The second equation will be:
= (9 + x)/2
= 4.5 + 0.5x
Answer:
(3.25, 1.5)
Step-by-step explanation:
<em><u>First, turn the 2nd equation into y=mx+b form:</u></em>
у+ 2x = 8
<u> -2x -2x</u>
y = -2x + 8
<u><em>Next Substitute:</em></u>
З(-2x+8) - 2x = -2
-6x + 24 - 2x = -2
-8x + 24 = -2
<u><em>Then simplify:</em></u>
-8x + 24 = -2
<u> -24 -24</u>
-8x = -26
x = 3.25
<em><u>Lastly, substitute x into any one of the original equations:</u></em>
y + 2 (3.25) =8
y + 6.5 = 8
<u> - 6.5 - 6.5</u>
y = 1.5
please give me brainliest i worked hard on this :,)
and its 1000% correct, i checked it i promise
