2 + 7 = 4 + 1 (x ) − x 4
may give brainliest only IF your explain how you got your answer. And I will thank you and all that (15 points:))

Answers

Answer 1
9 = 4 + x - 4x minus 4
5 = x - 4x
5 = -3x divide by -3
-3/5 = x
Answer 2
To solve this we know that 2+7=9 so for 4+1(x)-x4 to equal 9 you would first multiply x and 4 to get 4x. Next you would subtract 1x-4x which equals -3x+4 . What you do to the right you do to the left so 9-4=5. Which you the have 5=(-3x) so you then divide the 3x by 3 which leaves you with x. So x = -5/3 .

Brainlist for positive attitude and correct answer :D

Answers

Answer: The correct answer is:

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

How does the decimal point move when 50.2 is multiplied by 1102?

Answers

55,320.4 I think if I’m wrong sorry

Step-by-step explanation:

50.2 = 5.02 × 10¹

1102 = 1.102 × 10³

so,

50.2 × 1102 = 5.02 × 1.102 × 10³×10¹ =

= 5.02 × 1.102 × 10⁴

so, the decimal point moves 3 positions to the right :

Carlos needs an average of 90% or greater on his quiz scores to earn an A in science class for the quarter. Each quiz is worth 20 points. The scores of his first four quizzes are shown in the table. There is one more quiz this quarter.



Quiz Score
1 18
2 19
3 17
4 20


What is the minimum score Carlos can earn on the final quiz to earn at least a 90% average?

Answers

Answer: Carlos can score a minimum of 16 points

Step-by-step explanation:

each quiz is worth 20 points, so 20*5= 100 points in total (it is multiplied by 5 because he will be taking 5 tests in total), Carlos has earned a total of 74 points. In order for Carlos to receive a 90% average, he would need a 90/100, so 90-74= 16, therefore, Carlos needs a 16/20 in order to earn a 90% for the quarter.

On solving the provided question we can say that by percentage he need to scores 16 point in each

What is percentage?

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

Answer:

116%

Step-by-step explanation:

goal was 75 minutes = 100%

she did 87 minutes, so we know it's more than 100%

(87/75) * 100 = 1.16 * 100 = 116%

Answer:

116%

Step-by-step explanation:

Each students goal is 75 mins

100% = 75 mins

p = unknown percentage

p = 87 mins

87 ÷ 75 = p

87 ÷ 75 = 1.16

p = 1.16

Since 1.16 = 116%, p = 116%

Answers

Answer:

y= 125,000 (1.15x)

Step-by-step explanation:

Answer: y = 125000(1.15)^x

Step-by-step explanation:

The formula we use is y = p(1 + r)^x p is price and r is rate

the initial price is $125000 and the rate is 15%, or 0.15.

y = 125000(1 + 0.15)^x

y = 125000(1.15)^x
