Answer:
21:8
Step-by-step explanation:
<u>Given information:</u>
Lori (x) is 8 years old.
In 5 years (x + 5), Philip will be twice Lori's age (y + 5 = 2(x + 5))
<u>The missing value, y, is needed to find the ratio for Lori's and Philip's ages in the present. To find y, solve this equation:</u>
y + 5 = 2(x + 5) First, distribute the 2 into x + 5.
y + 5 = 2x + 10 Next, isolate the variable y by subtracting 5 from both sides.
y = 2x + 5 After that, add in the value of x, 8.
y = 2(8) + 5 Finally, simplify the right side to find Philip's age.
y = 16 + 5
y = 21
<u>Now for the easiest part: The ratio of Philip's age now to Lori's age now.</u>
because 21 is not divisible by any of 8's factors, the current ratio of 21:8 cannot be simplified further.
So, the ratio is 21:8
The midpoint is given by finding the average x-value and the average y-value, thus the formula would be:
M = ( (x1 + x2)/2, (y1 + y2)/2 ), where (x1, y1) and (x2, y2) are two points on the graph
1. We have two points here, the origin - ie. (0, 0) - and A(18, -6). Thus, using the formula above for the midpoint we get:
M = ( (0 + 18)/2, (0 + (-6))/2 )
M = (18/2, -6/2)
M = (9, -3)
2. Using the same approach, we can find the midpoint for this question using the points J(-9, 5) and K(21, -7):
M = ( (-9 + 21)/2, (5 + (-7))/2 )
M = (12/2, -2/2)
M = (6, -1)
The multiplication and divison equation involves using the '×' and '÷' operator on numbers. Few equations using the divison and multiplication operator are given below.
