Divide both sides by 2 2(x+2)=-
move constant to the right x+2=-2
calculate x=-2-2
x=-4
Answer:
15 students
Step-by-step explanation:
No. of boys students = No. of all students - No. of girls
no. of boys =50-15 = 35 boys
the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys
and the girls that will play the match are 5 girls
so, no of students chosen to play = 5+10=15 students

Growth meters per second = 4.8 ×

First, you need to convert standard form into a normal number.
4.8 ×

= 4.800000000
a) In one day there are 24 hours, therefore you will multiplying 4.800000000 and 24
4.800000000 × 24 = 115.2 = 115.2 ×

(standard form)
b) 365 days in a year, so multiply 4.800000000 and 365
4.800000000 × 365 = 1752 = 1.7 ×

(standard form)
Hope I helped (:
have a great day!
