You can write an equation to represent this situation. Let x represent the number of girls.
283 = x + (x + 27)
Here, we are adding the number of girls with 27 more people than this amount of girls. This will allow us to add the number of girls, x, with the number of boys, x + 27, to get a total of 283.
This equation can be simplified if we add the like terms together: the x's.
So,
283 = 2x + 27.
Since this is a multi-step equation, we must use the reversed order of operations; undo addition first.
283 - 27 = 2x + 27 - 27
256 = 2x + 0
256 = 2x
Now, we must undo multiplication by dividing.
256/2 = 2x/2
128 = 1x
So, x, the number of girls, is equal to 128.
Hope this helps you! :)
Answer:
9 units
Step-by-step explanation:
Answer:
10 times greater
Step-by-step explanation:
Because value of 5 in 503 is 5*100
Then the value of 5 in 53 is 5*10
So then value of 5 in 503 is 10 times greater than the value of 5 in 53
I hope this helps
Ok so the perimeter is the sum of all four sides, in this case, 26cm. The sides are then x, x, x+5, and x+5. 26=x+x+x+5+x+5 OR 26=4x+10.
x+5=length
x=width
subtract ten from each side:
16=4x
divide both sides by four:
x=4
Now we know the width. The length is the width plus 5.
4+5=9
Length: 9cm
Width: 4cm
It's 216 because you would just do the equation from left to right since pemdas doesn't really effect the order here
