Answer:

a = 40

Step-by-step explanation:

This is a multi-step equation using the distributive property and rational coefficents (fractions).  The first step is to complete the distributive property on both sides of the equation and multiply each term in the expression in parenthesis by the constant on the outside.  (3/4 x 2a) - (3/4 x 6) +1/2 = (2/5 x 3a) + (2/5 x 20).  When we multiply and simplify, we get 3/2a - 9/2 + 1/2 = 6/5a + 8.  Next step is to combine like terms:  3/2a  - 8/2 = 6/5a +8.  We then need to isolate the variable by using inverse operations:  3/10a = 12, then solve for 'a' by multiplying both sides by the reciprocal (10/3) to get a = 40.

HELP!Write the equation of the line fully simplified slope-intercept form.
xxTIMURxx [149]
Find slope first
Two points: (-5,-2) and (5,4)
(4+2)/(5+5) = 6/10 = 3/5 slope
So far: y = 3/5x + b
Plug in any of the point
-2 = 3/5(-5) + b, b = 1
Final equation: y = 3/5x + 1

2( 4c - 7 ) < 8 ( c - 1) - 6 if possible
4vir4ik [10]
Sure! Let's do this in order.
First, we can simplify the left side with the distributive property, getting us
8c-14
Next, we can simplify the right side with the distributive property, getting us 
8c-8-6.
That gives us 8c-14<8c-8-6.
We can subtract 8c from both sides, getting us
-14<-8-6
Simplify the right side to get
-14<-14
This inequality has no solution. This is because the variable is gone, and the remaining equation isn't true.

Given the table below, evaluate the following:
NeX [460]

Part A

See the image labeled "part A". We'll use the values marked in blue and red for f(2) and g(2) respectively. These values are the function outputs when the input is x = 2.

(f-2g)(x) = f(x) - 2*g(x)

(f-2g)(2) = f(2) - 2*g(2)

(f-2g)(2) = 1 - 2*3

(f-2g)(2) = -5

Answer: -5

=====================================================

Part B

See the image labeled "part B". We'll use the values marked in blue and red for g(-1) and f(0) respectively.

We have to start with g(-1) and then chain it to finding f(0) afterward.

g(-1) = 0

f(g(-1)) = f(0) = 9

Answer: 9

=====================================================

Part C

See the image labeled "part C". We'll use the values marked in blue and red for g(-2) and g(-3) respectively.

Because g(-2) is the innermost function, it must go first, then g(-3) can go next.

g(-2) = -3

g(g(-2)) = g(-3) = 8

Answer: 8

After kicking, one coach likes to play practice games with 6 players on each
Nezavi [6.7K]

There are many possible numbers. First, lets begin with the data there giving us. They are saying she wants to play a practice game so there at least needs to be 2 teams. It also says, that she wants 6 players on each team, nothing more and nothing less. So, for this we are going to use the 6 timetables.

6 x 2 = 12

6 x 3 = 18

6 x 4 = 24

6 x 5 = 30

6 x 6 = 36

There are also more numbers, but I am not doing those. But, for your first five, there can be 12, 18, 24, 30, and 36 students to be on the teams for the practice game.
