It will be 5x3=15+23=38 so 38 pounds the puppy weigh
Step-by-step explanation:
I used a co-ordinate graph and place the ticket booth at the origin then I chose difference of four but you can choose any and place three events equidistant from the origin by using the X- and Y- axis to easily determined a distance of 4 from the origin .
(0-4, 0) =( 4,0)
(0+4, 0) = (4 ,0)
(0, 0+4) = (0, 4)
if the both are placed first u would need to find the equation of a circle that contains all three points and place the booth at centre
you do this by creating the system of 3 equations inputting the x,y coordinates of each booth and solving for h,k,r
equation of a circle (X-H) 2 +( Y-K) 2 = r2
Hope It helps
:DD have a nice day
Let the initial number of girls be x, this represents 40% of the dancers.
Total number of dancers will therefore be:
100/40*x=2.5x
When 15 more girls joined, the new number of girls was:
x+15 this represents the total percentage of 52%. The new number of dancers became:
2.5x+15:
therefore the new percentage of girls can be expressed as follows:
(new number of girls)/(new number of dancers)×100
(x+15)/(2.5x+15)×100=52
(x+15)/(2.5x+15)=0.52
x+15=0.52(2.5x+15)
x+15=1.3x+7.8
15-7.8=1.3x-x
7.2=0.3x
x=7.2/0.3=24
The number of students after additional number of girls will be:
2.5x+15
=2.5×24+15
=60+15
=75 students
Answer:
2x+8
Step-by-step explanation:
2 times x = 2x. 2 times 4 = 8.
