Mrs. Blake needs to hire a babysitter. Kelsey charges $6 per hour plus a $5 fee. Lauren charges $4 per hour, plus a $10 fee. Mrs. Blake set up this equation to figure out for what amount of time both babysitters charge the same.6h + 5 = 4h + 10 What is the correct sequence of steps to solve Mrs. Blake’s equation? A. Subtract 6h from both sides. Subtract 5 from both sides. Divide each side by –2. B. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 2. C. Subtract 4h from both sides. Add 5 to both sides. Divide each side by 2. D. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 6.

Answer:
B. The axis of symmetry is x=1.
F. The vertex is (1, 7).
G. The y-intercept is (0, 10).
Step-by-step explanation:
A graph of the function is helpful sorting this out.
_____
For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Here, that is ...
x = -(-6)/(2·3)
x = 1 . . . . axis of symmetry
This is also the x-coordinate of the vertex. The y-coordinate of the vertex can be found by evaluating the expression for this value of x:
3·1² -6·1 +10 = 7
so the vertex is (1, 7).
__
The y-intercept is the constant, the value of the function when x=0. Here, that is 10, so the coordinates of the y-intercept are (0, 10).

Answer:
3 1/2 =x
Step-by-step explanation:
(1/2) / 4 = x/28
Using cross products
1/2 * 28 = 4*x
14 = 4x
Divide each side by 4
14/4 = 4x/4
7/2 = x
3 1/2 =x
Answer:
Step-by-step explanation:
Cross Multiplying
=> 1/2 * 28 = 4x
=> 14 = 4x
=> 4x = 14
Dividing both sides by 4
=> x = 14/4
=> x = 7/2
=> x =

Answer:
37 students are in the class
Step-by-step explanation:
There are 8 regions which the most inclusive clue is the inner one with 12.
- "14 on a plane and boat" so we fill the intersection with plane and boat with 14-12=2
- "20 on train an boat" 20-12=8 in the intersection
- "15 on plane and train" = 15-12 = 3
now we look at this:
- "22 students have been on a plane" 22 - (2+12+3) = 5 on the plane
- "28 on a train" 28 - (12+8+3) = 5 on the train
- "23 on a boat" 23-(12+8+2) = 1 on the boat
Just add up all the 8 numbers in the regions:
12+2+8+3+5+5+1+1=37
In a class, 22 students have been on a plane, 28 on a train, 23 on a boat, 15 on a plane and train, 20 on a train and boat, 14 on a plane and boat, and 12 on all three, and 1 on none of them. How many students are in the class?
(1, 5, 3, 12, 2, 5, 8, 1) = 37
