There are three groups. One group for girls. One group for half the boys which is equal to one group of girls and another identical sized group of boys because there are twice as many boys as girls.
48=total
3=number of groups
48/3=16
16 is equal to the number of girls because it is equal to half the number of boys
16*2=32
32+16=48
Number of boys plus number number of girls: 32+16=48
Answer:
THERES MUCH INFORMATION EXCLUDED!
Step-by-step explanation:
She travels 7 miles per 25 hours
If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 = 100 miles per hour (mph).

Answer:
The table is attached as a figure
The given equation is ⇒⇒⇒⇒ y = 2x
To solve this equation, we need to pick numbers from the table then this number will be substituted into the equation to find y
we need 3 solutions . so, we need to pick 3 numbers of x
From the table, let us choose x = 0
y = 2x
y = 2 * (0)
y = 0
From the table, let choose second value of x such as x = 1
y = 2 * (1)
y = 2
From the table, let choose third value of x such as x = -1
y = 2 * (-1)
y = -2
So, the picked three solutions are
y = 0 at x = 0
y = -2 at x = -1
y = 2 at x = 1
X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
The y-intercept of the exponential function is - 2 less than - the y-intercept of the linear function.
Each time in the table the output has 4 more than the previous output, so just subtract 8 from the from the 20 output to find out that the y-intercept is 12.
The y-intercept is represented on the graph at the point where y=0 which is 10 by the way.
10 is 2 less than 12.
