Bradley and 23 of his classmates went on a trip to the aquarium. there are 8 more boys than girls on the trip. write a system of equations to model the problem. then solve the system algebraically. how many boys and girls were on the trip?

Step-by-step explanation:

Total number on the trip is 24

Let the number of girls be x

Then the boys are x + 8

So... x + x + 8 = 24

2x + 8 = 24 This is the equation

2x = 24 - 8

2x = 16

x = 16/2

x = 8

Number of girls = 8

And number of boys = x + 8

Which is = 8+8 = 16

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
