Answer 1

Answer:

The distribution at the 2nd line

Step-by-step explanation:

I believe where Gabby went wrong was in her multiplication distribution

12*5=60 not 72

hope this helps!!

Answer 2

The value of y form the given equation is -65/11. Gabriela did mistake in second step while multiplying 12 and 5 and - sign into a bracket.

The given equation is 12(5+2y)=4y-(5-9y).

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation can be solved as follows:

12(5+2y)=4y-(5-9y)

⇒ 60+24y=4y-5+9y

⇒ 60+24y=13y-5

⇒ 24y-13y=-5-60

⇒ 11y=-65

⇒ y=-65/11

Therefore, the value of y form the given equation is -65/11. Gabriela did mistake in second step while multiplying 12 and 5 and - sign into a bracket.

A discount store bought two dozen cameras for $14 each.
After the cameras didn't sell for a long period, the store
decreased their selling price to $10.99 per camera. What was the
store's overall loss on the two dozen cameras?

Answers

Answer:

72.24

Step-by-step explanation:

Price for each camera = 14

Number of camera = 2dozen = 12 x 2 = 24

Total cp = 24 x 14 = 336

~~~~~~~~~~~~~~

Price for each camera=  10.99

Number of cams = 24

Total sp = 10.99 x 24 = 263.76

Loss = 336 - 263.76  = 72.24

Un elev a depus la banca suma de 250 lei. Știind ca banca oferă dobânda anuala de 1%,iar stația impozitează dobânda cu 16%,aflati ce suma va avea elevul după un an de depunere.

Answers

Răspuns:

292,50

Explicație pas cu pas:

Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17

Suma principală depusă, P = 250

Suma totală, A după 1 an poate fi calculată astfel:

A = P (1 + rt)

Unde ; r = rata dobânzii; t = timp

A = 250 (1 + (0,17 * 1))

A = 250 (1,17)

A = 292,5

3x^2-9x+0
Factor the trinomial

Answers

Answer:

3x (x-3)

Step-by-step explanation

3x^2 - 9x + 0

The equation.

3x^2 - 3^2 × x

What I did here is that I factored out 9x to 3^2 times x.

3x (3x^2 all over 3x - 3^2 × x/ all over 3x)

So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.

3x (x^2-1 - (3^2-1) )

You simplify to get the final answer.

3x (x-3)

B)15,225.88
C) 19,157.48
D) 18,225.88

Answers

Answer:

None of the above, it should be $4760

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 3500 × 0.12 × 3 = 1260

I = $ 1,260.00

The simple interest accumulated

on a principal of $ 3,500.00

at a rate of 12% per year

for 3 years is $ 1,260.00

Answers

Given:

The probability that Jamil will be late for work is 0.2.

To find:

The probability that Jamil will not be late for work.

Solution:

We have,

P(Jamil will be late) = 0.2

We know that,

P(Jamil will not be late) = 1 - P(Jamil will be late)

                                       = 1 - 0.2

                                       = 0.8

Therefore, the probability that Jamil will not be late for work is 0.8.
