Answer:

PEMDAS does apply but not with the parentheses

The answer is −3g−4 btw

Explanation:

Let's simplify step-by-step.

−2g+7−(g+11)

Distribute the Negative Sign:

=−2g+7+−1(g+11)

=−2g+7+−1g+(−1)(11)

=−2g+7+−g+−11

Combine Like Terms:

=−2g+7+−g+−11

=(−2g+−g)+(7+−11)

=−3g+−4

You have 20 quarters and then find 40% more and then spend 75% how much money do you have left
kirza4 [7]

You have $1.75 left

Step-by-step explanation:

Given,

Number of quarters already have = 20

Percent of quarters found = 40% of already have

Number of quarters found = \frac{40}{100}*20

Number of quarters found = \frac{800}{100}

Number of quarters found = 8

New total = 20+8 = 28 quarters

Percent of quarters spent = 75%

Number of quarters spent = \frac{75}{100}*28

Number of quarters spent = \frac{2100}{100}

Number of quarters spent = 21

Quarters left = 28-21 = 7

1 quarter = 25 cents

7 quarters = 25*7 = 175 cents

$1 = 100 cents

175 cents = \frac{175}{100}=\$1.75

You have $1.75 left

Solving quadratic equations by factoring <br> m(m-3)=0
KatRina [158]
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3

Two diced are rolled. What is the probability that the sum of two numbers on the dice will be 4? 11/121/40
makkiz [27]

Each die has 6 possible outcomes (the numbers from 1 to 6).

If we roll two dices, the total number of outcomes is 6 * 6 = 36.

From these outcomes, the ones that have a sum of 4 are:

(1, 3), (2, 2) and (3, 1).

So, if we have 3 wanted outcomes from a total of 36, the probability is:

P=\frac{3}{36}=\frac{1}{12}

Therefore the correct option is the second one.
