Answer:
There are <u>35 boys</u> in the class.
Step-by-step explanation:
Girls to Boys ratio = 3:7
Total number of students in class = 50
Let total number of girls be '3x' and total number of boys be '7x'
Total number of girls + Total number of boys = Total number of students
3x + 7x = 50
10x = 50
x = 50/10
x = 5
Total number of girls = 3 × 5 = 15
Total number of boys = 7 × 5 = 35
Answer:
2x-15
Step-by-step explanation:
Sara has x dollars

x+x-15
=2x-15
Answer:
(−3,6)
(−2,3)
(−1.2)
(0,3)
(1,6)
Step-by-step explanation:
The correct answer to this question is 4.
In order to solve this problem, first make an image on your mind how the image is dilated.
The coordinate points at first is (1.5, 2.0). After dilation from the origin, the points became (6.0, 8.0)
Looking at it in fraction form, (new / old) we have
6.0 / 1.5 = 4.0
8.0 / 2.0 = 4.0
The quotient of each fraction yields to 4.0. This means that a = 4.
