Answer:

3+5n=5(n+2)-7*

We move all terms to the left:

3+5n-(5(n+2)-7*)=0

We calculate terms in parentheses: -(5(n+2)-7*), so:

5(n+2)-7*

We add all the numbers together, and all the variables

5(n+2)

We multiply parentheses

5n+10

Back to the equation:

-(5n+10)

We get rid of parentheses

5n-5n-10+3=0

We add all the numbers together, and all the variables

-7!=0

There is no solution for this equation

A local amateur ice skater estimates that the probability she will place first in the next regional competition is 0.43. What ar

Nady [450]

The odds that local amateur ice skater will win in next regional competition when probability is given will be 43 to 57.

We have,

Probability that ice skater will place first in the next regional competition i.e. P = 0.43,

And,

Now,

According to the question,

The odd when probability is given is find out by using the below mentioned formula,

i.e.

Odds = $\frac{P}{1-P}$

Now,

Substituting the value of probability,

i.e.

Odds of winning this competition = $\frac{0.43}{1-0.43}$

On solving we get,

Odds of winning this competition = $\frac{43}{57}$

i.e.

The Odds of winning this competition are 43 to 57.

Hence we can say that the odds that local amateur ice skater will win in next regional competition when probability is given will be 43 to 57.

Which table of values could be generated by the equation 4y-2x=16

S_A_V [24]

X: -4, -2
Y: 2, 3

When you plug -4 and 2 it looks somewhat like this, 4(2)-2(-4)= 8+8+16. Then -2 and 3 would look something like this, 4(3)-2(-2)= 12+4=16.

vodomira [7]

Volume equal area of base time height

so than we consider the base this triangle for what is given area and in this way we have the height equal this edge with length equal 6 so the volume will be equal 12*6=72 m^3

hope this is understandably sure easy and will help you

Determine the domain and range of this set of ordered pairs.

Darya [45]

Answer:

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}

Step-by-step explanation:

{(2,4), (8,-3), (-5,-1), (4,6), (6,7), (9,0)}

The domain is the input and the range is the output

domain is { 2,8,-5,4,6,9} and the range is {4,-3,-1,6,7,0}

We put the numbers in order from smallest to largest

Domain = {-5,2,4,6,8,9), range = (-3,-1,0,4,6,7}
