65:x = 13:15
Divide 65 by 13.
65/13=5
Multiply 15 by 5 for the proportionate factor.
75.
There are 75 girls in the classroom.
We're looking for the total so we need to add 65 with 75.
65+75= 140.
There are 140 total students.
Last choice I think good luck tho
Answer:
y = 2x/3 + 4
Step-by-step explanation:
The line passes through (-6, 0) and (0, 4)
slope = (4 - 0)/(0 - (-6)) = 4/6 = 2/3
y = (2/3)x + b
when x = 0, y = 4, so
4 = (2/3)*0 + b
b = 4
so
y = 2x/3 + 4
Answer:
a) number 2 and 3 appeared a minimum number of times
b) number 5 appeared a maximum number of times
c) number 1, 4 and 6 appear an equal number of times (4 times). Also number 2 and 3 appear an equal number of times (1 time)
d) Even numbers turned up 9 times. The even numbers in a dice are 2 4 and 6. Add up how many times they came up: 1+4+4=9
f) Odd numbers turned up 11 times. The odd numbers in a dice are 1, 3 and 5. Add up how many times they came up: 4+1+6=11
Slope is m= y2- y1 / x2- x1.
Billy flipped both where the numbers go, and in which order they should be in.
It should be -5-5 / -2-2 giving you zero (0).
