Answer:

The cost of the shirts are $40 and $24

Step-by-step explanation:

Let

x ----> the cost of one shirt

y ----> the cost of the other shirt

we know that

x+y=64 ----> equation A

I assume that the cost x is greater than the cost y

so

x-y=16 ----> x=y+16 ---> equation B

solve the system by substitution

substitute equation B in equation A

y+16+y=64

solve for y

2y=64-16

2y=48

y=\$24

Find the value of x

x=y+16 ---->  x=24+16=\$40

therefore

The cost of the shirts are $40 and $24

x+y=64 and x-y=16 can be used to solve the system.

Step-by-step explanation:

Let,

x,y be the two shirts.

According to given statement;

Bob spent $64 on both shirts;

x+y=64    Eqn 1

The difference between the costs of the shirts was $16 means subtraction;

x-y=16      Eqn 2

x+y=64 and x-y=16 can be used to solve the system.

Stephen says that the numbers 38 and 40 are relatively prime. explain why he is incorrect in making this statement
bonufazy [111]

When you say that two numbers are relatively prime, it means that both numbers do not have a common factor except 1. Stephen is incorrect because 38 and 40 are both multiples of 2.

I hope I answered your question. Thank you <span>J</span>

Miguel and his brother Ario are both standing 3 meters from one side of a 25-meter pool when they decide to race. Miguel offers
Westkost [7]

Answer:

Miguel start to swim when Ario has traveled 4.4 m.

Step-by-step explanation:

The total lenght of the pool is 25.

Since both of them standing 3 m from one side of the pool, then, the total distance both need to cover is 25-3 m= 22 m.

Assume that the distance traveled by Ario before Miguel start to swin is x. That means, the remaining distance to Ario (to cover the total size of the pool) is 22-x.

Then, in acoordance to the problem, the ratio between these two distances must be equal to 1/4.

That is,

\frac{x}{22-x}=\frac{1}{4} .

So, we need to obtain x from this equation. We must note that x\neq 22, otherwise we have a zero in the denominator.

So, we rearrange the equation,

4x=22-x (Multiplying both sides of equation by (4(22-x)).

Then, 5x=22.

Therefore, x=4.4 m.

100,000 random people were tested for Condition A. Roberto's doctor told him he tested positive for Condition A. If the test is
Studentka2010 [4]
The answer would be: <span>99.0%
</span>
The disease is rare with a prevalence of <span>one out of every thousand people have it. That means, the chance of Roberto has the disease without any test would be 1/1000 or 0.1%
The test sensitivity is 99%, which mean 99% of people with positive test result would have the disease. The chance is should not be influenced by the disease prevalence. </span>
