Answer:

Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)

Step-by-step explanation:

All sides of a square are congruent. "s" represents the square's perimeter:

s=4x.

"r" is the rectangle's perimeter:

r= 4x+26

since the perimeter = 2W + 2L:

2W + 2L= 4x+ 26

and W=x, so:

2x + 2L= 4x + 26

Subtract from both sides:

2L= 2x +26

Divide both sides:

the length of the rectangle "L"= x +13.

B) Plug 5 into the equations:

L= 5+ 13 or 18.

2(18) + 2(5)= r

36+ 10 = r or 46

s= s+ 26

s= 46-26 or 20.

20/4= 5...

It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 could be the value of x.

C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.

L=w+13

Answer:

x = 1

y = 1

Step-by-step explanation:

System of Equations

We are given the system of equations:

2x + y = 3

x = 2y - 1

Substituting x in the first equation:

2(2y - 1) + y = 3

Operating:

4y - 2 + y = 3

5y = 3 + 2

y = 5/5 = 1

y = 1

Since:

x = 2y - 1

Then:

x = 2(1) - 1

x = 1

Solution:

x = 1

y = 1

the total cost after tax to repair Kimber’s cracked phone is represented by 00.4(30h)+30h Where h represents the number of hours

Serjik [45]

we have that

the total cost is

$0.040(30h)+30h$

In this equation the term 30h represent the cost due to h hours at at unit of 30

and the term 0.040(30h) is equal to calculate the 4% of (30h)

in this problem the tax rate is equal to 4%

therefore

the answer is

The term 0.040(30h) represents the amount of tax she must pay

Seventy percent of children who go to the doctor have fevers. Of those with fevers, 30% also have a rash. Of those without fever

Allisa [31]

Answer:

The probability that a child with a rash does not have a fever is 22%

Step-by-step explanation:

1. Probability of having fever:

$P(fever)=0.70$

2. Probability of not having fever:

$P(not fever)=1-P(fever)\\P(not fever)=1-0.70\\P(not fever)=0.30$

3. Probability of fave fevers and a rash:

$P(fever and rash)=(0.70)(0.30)=0.21$

4. Probability of having a rash but not a fever:

$P(rash and not fever)=(0.30)(0.20)=0.60$

5. Probability of having a rash:

$P(rash)=P(rash and fever)+P(rash and no fever)\\P(rash)=0.21+0.06=0.27$

6. Probability a child with a rash does not have a fever

$P=\frac{P(rash and not fever)}{P(rash)} =\frac{0.06}{0.27} =0.22$

22% of the child at the doctor's office with a rash does not have a fever.
