Answer:

Elga is 30 and Alvin is 15

Step-by-step explanation:

45-15=30

30-15=15

30+15=45

Answer:

[tex]\huge\boxed{\text{Alvin = 15, Elga = 30}}[/tex]

Step-by-step explanation:

In order to find Alvin and Elgas age, we can use a system of equations.

Let us assume that [tex]a[/tex] represents Alvin's age and [tex]e[/tex] represents Elgas age.

We can create two equations:

[tex]a = e-15[/tex]

[tex]a+e=45[/tex]

We can now use substitution to find each value. Let's substitute [tex]a = e-15[/tex] into [tex]a+e=45[/tex] as a.

[tex](e - 15) + e = 45[/tex]

We can now simplify this equation and solve for e.

[tex]2e-15 = 45\\2e = 60\\e = 30[/tex]

So we know that Elga is 30 years old. To find Alvin's age, we can substitute the value of e (30) back into one of the equations. Let's do it for [tex]a+e=45[/tex].

[tex]a + 30 = 45\\a = 45-30\\a=15[/tex]

So Elga is 30 years old and Alvin is 15 years old.

Hope this helped!

Answer:

Step-by-step explanation:

Let the time use by other one technician be x

if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)

The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.

First technician = x

Second technician = x-6

Sum of the time taken

t = x+ (x-6)

Hence option C is correct

Answer:

(3, -9)

Step-by-step explanation:

5x + y = 7

-x - 2y = - 15

What we can do is multiply the second equation by 5, as we try to combine both equations to get rid of x.

5x + y = 6

-5x - 10y = 75

-9y = 81

y = -9

Now we plug y back in.

5x - 9 = 6

5x = 15

x = 3

Answer:

740,000

Step-by-step explanation:

The ten-thousands digit is the 4.

Change all digits to the right of the 4 to 0.

742,617 becomes 740,000.

Since the first digit to the right of the 4 is 2, and not a digit from 5 through 9, we keep the 4 and do not change it to 5.

Answer: 740,000

(x+2) (x+1)=0

Isolate the X

=> [tex]\left(x+2\right)\left(x+1\right)=0[/tex]

Divide both sides by the coefficient:

=>[tex]x=\begin{bmatrix}-2\\-1\\\end{bmatrix}[/tex]

Answer:

the completed square is x=1, -3

Answer:

the chances both are is=.64%

the chances of only one is=15.36%

Step-by-step explanation:

8%=.08

.08x.08= .0064=.64%

1-(1-0.08)×(1-0.08)

1-.92x.92

0.1536=

15.36%

a) The probability both are math-phobic: 0.0064 or 0.64%.

b) The probability that at least one is math-phobic is 0.1536 or 15.36%.

To determine the probability that both selected people are math-phobic, we can use the multiplication rule of probability.

Since the selection is random, the probability that the second person is math-phobic is also 0.08.

To find the probability that both events occur, we multiply the individual probabilities:

Probability of both being math-phobic = 0.08 x 0.08 = 0.0064

Therefore, the probability that both selected people are math-phobic will be 0.0064 or 0.64%.

To find the probability that at least one person is math-phobic, we can use the complement rule of probability.

The probability that the first person is not math-phobic ;

1 - 0.08 = 0.92.

Similarly, the probability that the second person is not math-phobic is also 0.92.

Probability of none being math-phobic = 0.92 x 0.92 = 0.8464

Probability of at least one being math-phobic = 1 - 0.8464 = 0.1536

Therefore, the probability that at least one person is math-phobic is 0.1536 or 15.36%.

Answer:

k = - 10

Step-by-step explanation:

k - 3(k + 5) - 0.5 = 3(0.25k + 4) ← distribute parenthesis on both sides

k - 3k - 15 - 0.5 = 0.75k + 12

- 2k - 15.5 = 0.75k + 12 ( subtract 0.75k from both sides )

- 2.75k - 15.5 = 12 ( add 15.5 to both sides )

- 2.75k = 27.5 ( divide both sides by - 2.75 )

k = - 10

Answer:

4m

Step-by-step explanation:

Expressions do not have equal signs,  So for the product of 2 things we just multiply them together.

4m

Answer:

4 × M = P

Explanation:

A product is the result of a multiplication expression, so in this case, We're using variables to represent numbers.

P = Product

We're multiplying 4 and M, so lets rewrite this.

4 × M

This is an incomplete expression, but what will we use for our product We can use a variable. Our variable is P. So lets complete this expression.

4 × m = p.

Or, we can put it in a less complex way.

4m.

This also is a incomplete expression, but it means 4 × m.
