This is the equation we would use for this problem.
Now when we cross multiply, we get:
35(600)=100x
Simplify:
21000=100x
Divide each side by 100 to get x b itself:
210=x
So, as you can see, 210 is 35% of 600
Y = mx + c
m = 2
y = 2x + c
At (5, 0)
0 = 2(5) + c
c = -10
y = 2x - 10
Answer:
<h2><em>
[2(x+y)-25]cm</em></h2>
Step-by-step explanation:
Let the height of their oldest sister isabella be z centimeters. Roger is x centimeters tall and Olivia is y centimeters tall.
If their oldest sister, Isabella, is 25 centimeters shorter than the double of the sum of Roger and Olivia's height, this can be expressed as shown;
First let us get the sum of Roger and Olivia's height;
The sum of Roger and Olivia's height = (x+y)cm
The double of the sum of their ages = 2* (x+y)cm = 2(x+y)cm
Now if Isabella, is 25 centimeters shorter than the double of the sum of their ages, the expression will be [2(x+y)-25]
<em>Since the height of isabella is z, the expression that model isabella's height will be expressed as z =[2(x+y)-25]cm</em>
Answer:
x+y=31
Step-by-step explanation:
I'd say that would be the equation bc it doesn't really give ages. Although I could be wrong so sorry if I am
M=16
16-9=7
hope this helped:)
