30. A mom bought her kids 3 cartons of milk
for $1.25 each and 6 doughnuts. The total
cost was $6.90. Write an equation to
determine the cost of a doughnut.

Answers

Answer 1

Answer:

x = (1.25 * 3 - 6.90) divided by 6

Step-by-step explanation:

this will get the price of all the milk, then take it out of the total price, then divide it by 6 because there are 6 donuts, this will give you the price of 1 donut

Answer 2

Answer:

$3.15

Step-by-step explanation:

$1.25x3=$3.75

$6.90-$3.75=$3.15

What is the solution to the equation x÷8−6=3?

A. x=1

B. x=24

C. x=48

D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.

Answers

Answer: D. x=72

Step-by-step explanation:

With the equation x/8-6=3  we can start solving by first moving the "-6"

                 x/8-6(+6)=3(+6)

                 x/8=9             <-- Rewrite equation after adding "6" to both sides

                 x/8(*8)=9(*8)  <--- Multiply both sides by 8

                 x=72              <-- After multiplying, solution is found

A letter from the word CONFIDENCE is chosen at random, then a card is drawn from a standard deck. What is the probability of getting a consonant, them a red card or ace.

Answers

Answer:

9/26

Step-by-step explanation:

Word : CONFIDENCE

Consonants in word : C, N, F, D, N, C = 6

Total alphabets = 10

Probability =required outcome /Total possible outcomes

Probability (consonants) = 6 /10 = 3/5

Number of red catds in deck = 26

Number of aces in a card deck = 4

Total number of cards = 52

P(red) or P(ace)

(4/52) + (26/52) = (4 + 26) / 52 = 30 / 52 = 15 / 26

P(getting a consonant, then a red card or ace)

(3 /5) * (15/26) = (3 * 15) / (26 *5) = 45/130 = 9/26

The graph shown below represents a ladder leaning against wall the bottom of the latter is 4 feet from the wall in the top of the ladder reach is 20 feet above the ground what is the slope of graph (I’m so sorry I don’t have a picture)

Answers

Hi I’m trying but yeeeeah

Answer:

C.) -5

Step-by-step explanation:

The slope formula is rise/run, in other words, rise divided by run or the y variable divided by the corresponding x variable.

In this question, we are told that the y-value is "20 feet above" meaning this is the rise and the run is "4 feet from"

To find the slope all we have to do is divide 20 by 4 giving us 5. Since the ladder is going down we know that we have to place a negative sign before the slope giving us our final answer of -5

Answers

Answer:

No, A is

Step-by-step explanation:

You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.

Answer:  Choice A.  (0,0)

============================================================

Explanation:

Let's check if choice C is the answer or not

We will plug in x = -2 and y = 1 into the inequality to get

y - 3x < 1

1 - 3(-2) < 1

1 + 6 < 1

7 < 1

That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.

---------------

It turns out that choice A is the answer because

y - 3x < 1

0 - 3(0) < 1

0 - 0 < 1

0 < 1

Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.

I'll let you check the other answer choices. You should find them to be false
