A pineapple is 7 times as heavy as an orange. the pineapple also weighs 870 grams more than the orange. what is the total weight in grams for the pineapple and orange

Answers

Let's translate each sentence into "Math".

Pineapple = p

Orange = x

is means equal

 

Pineapple is 7 times as heavy as an orange:  p = 7x

Pineapple weighs 870 grams more than orange. p = 870 + x

 

Substitute  p = 7x  into the second equation:

7x = 870 + x

Subtract  x from both sides

6x = 870

divide by 6

x = 145

 

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.

The orange weighs 145 grams.

The pineapple weights 7 times the orange = 7(145) = 1015 grams.

Final answer:

To multiply 14 by 25, you multiply each digit of 25 by 14 individually and then sum the results, yielding a product of 350.

Explanation:

The student has asked to multiply 14 by 25 and express the answer in simplest form. Multiplication is a basic arithmetic operation, and it is a straightforward process. To multiply 14 by 25, you can use the following steps:

Multiply the ones digit of the second number by the first number: 5 x 14 = 70.

Multiply the tens digit of the second number by the first number: 2 x 14 = 28. Remember that since this 2 represents 20 in the number 25, the result (28) will actually represent 280 when you include it in the final answer.

Add the results from steps 1 and 2: 70 + 280 = 350.

Thus, the product of 14 and 25 is 350.

Of the candy, 1/2 are Skittles, 1/4 of the remaining pieces are M&Ms and 3/4 of the rest are Life Savers. The remaining pieces are Sour Patch Kids. What percent of the total pieces of candy are Sour Patch Kids?

Answers

Given condition is- The bag contains individual pieces of Skittles, M&Ms, Life Savers and Sour Patch Kids.

Let the total number of candies in the bag be = x

Then, Skittles are [tex]\frac{1x}{2}[/tex]

Candies left = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]

M&Ms are = [tex]\frac{1x}{8}[/tex]

Now remaining candies are= [tex]\frac{3x}{8}[/tex]

Now Life savers are = [tex]\frac{9x}{32}[/tex]

Now adding all these 3 candies

[tex]\frac{x}{2}+ \frac{x}{8}+\frac{9x}{32}[/tex]

=[tex]\frac{29x}{32}[/tex]

Now the remaining candies sour patch will be =

You have to be awfully careful with this inequality. If can cause you all kinds of grief.

find the inverse of y=-12x+7

Answers

You want to solve for x here.

When finding the inverse of a function, you might get this form of the equation:
f(x) = -12x + 7
And you would have to change the f(x) into a (y). However, this equation already has y in place of f(x), so you can just get started!

To find the inverse you want to solve for x, and, thus, you must ISOLATE x from every other term and variable.

1) (subtract 7 from each side)
y - 7 = -12x

2) (divide -12 from each side)
(y/-12) + (7/12) = x

Now that x is now isolated, you have your answer. Your teacher, however, might want you to change the (y)s in your answer to (x)s.

So the inverse of y = -12x + 7 is
(y/-12) + (7/12)

OR (if your teacher wants you to change your (y)s to (x)s in your inverse solution (which they probably do)):

The inverse of y = -12x + 7 is
(x/-12) + (7/12)
Final answer:

The inverse of the equation y = -12x + 7 is found by replacing 'y' with 'x' and 'x' with 'y', then solving the equation for y. The result is y = 1/12x - 7/12.

Explanation:

The equations y = -12x + 7 is given, and you are asked to find the inverse of this equation. The first step to finding the inverse of a function is to replace 'y' with 'x' and 'x' with 'y'. So, our equation becomes x = -12y + 7. Now, you need to solve this equation for y to find the inverse function. You do this by subtracting 7 from both sides then dividing by -12, which yields: y = (-x + 7) / -12 or y = 1/12x - 7/12. This is the inverse of the given function.

Mason is skiing with friends he starts at an elevation of 420 feet he descends 600 feet down the mountain into a valley what is his elevation when he stops

Answers

420-600=-180 Hope this helps

Mason's ending elevation after descending 600 feet from a starting elevation of 420 feet is -180 feet, meaning he is below sea level.

To solve for Mason's elevation after his descent, we need to subtract the distance he traveled downward (600 feet) from his starting elevation (420 feet). We can represent this mathematically as:

Elevation after descent = Starting elevation - Descent

Elevation after descent = 420 feet - 600 feet

Elevation after descent = -180 feet

Therefore, when Mason stops, he is at an elevation of -180 feet. This means he is 180 feet below sea level, assuming the initial elevation is measured from sea level.

solve for x: 27=17+2x

Hello!

Here's how to solve for x.

27=17+2x

Our first step is to subtract 17 from both sides, leaving us with

27-17=17(-17)+2x --- > 10=2x

We then divide both sides by 2 to isolate  x!

10/2=2x/2

10 divided by 2 gives us 5 meaning that x=5


[tex]x = 5[/tex]
move variable to left side and change its sign
[tex]27 = 17 + 2x[/tex]
to
(you also move the constant to the right and change its sign)
[tex] - 2x = 17 - 27[/tex]
and then calculate the operation in this case you find the difference
[tex] - 2x= 17 - 27 = - 10 \\ - 2x = - 10[/tex]
you then divide both sides of the equation by -2 since the inverse operation of multiplying is division

Fifteen percent of an employee’s taxable income is collected each paycheck. Before taxes are removed from each paycheck, $350 of tax-exempt expenses is taken out. If the variable x represents the employee’s pay before tax-exempt expenses and taxes are removed, which expression represents the employee’s take-home pay after these deductions?

Answers

Answer:

0.85(x - 350)

Step-by-step explanation:

Here "x" represents the pay before tax.

Take exempted amount = 350.

The taxable amount = x - 350.

The tax rate = 15% = 15/100 = 0.15

Take home pay after the tax deduction = Taxable amount - tax

= (x - 350) - 0.15(x - 350)

Now we have to simplify this.

= (x - 350)(1 - 0.15)

= (x - 350)(0.85)

The employee’s take-home pay after these deductions= $0.85(x - 350).

Franceca has five more pineapples than filip. If Francesca has f pineapples, write an expression for the number of pineapples filip has

Answers

Five less then f

f-5

Final answer:

The expression for the number of pineapples Filip has, given that Francesca has 'f' pineapples and that she always has 5 more than Filip, is 'f - 5'. This algebraic expression signifies that Filip will always have five less than whatever amount Francesca has.

Explanation:

The subject of your question relates to algebraic expressions, which is an essential concept in Mathematics. To create an expression that represents the number of pineapples that Filip has, we need to understand the relationship provided in the question, which is that Francesca has five more pineapples than Filip. If Francesca has 'f' pineapples, we can express the number of pineapples Filip has as 'f - 5' because Filip will always have five less than whatever amount Francesca has.

Here's why that is: Let's say Francesca has 10 pineapples. According to the question, Filip would have 10 (Francesca's pineapples) - 5 (since he has 5 less) = 5 pineapples. No matter how many pineapples Francesca has, if you subtract five from it, you get the number of pineapples that Filip has.

This example demonstrates how algebraic expressions are used to represent relationships or scenarios mathematically. Remember, 'f - 5' is the simplified form of the expression, and it illustrates the consistent difference of 5 pineapples between Francesca and Filip.

Answers


Looking at the plots, we can see that the number of candies in Brand A bags seems to be about 55 give or take about 5 candies or so.

The number of candies in Brand B bags appears to be about 55-60 give or take 10 candies.

Intuitively, we can tell that Brand B is LESS consistent than Brand A, since Brand B's candy numbers are "all over the place." But, at the same time, it looks like Brand B bags tend to have more candy than Brand A.

The number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Lets compare the dot plots of the two brands.

In Brand A,

The number of candy pieces per bag ranges from 52 to 62, and the dots are relatively evenly spread out across this range.

In Brand B,

the number of candy pieces per bag ranges from 44 to 69, and the dots are more spread out, with a larger range of values.

As we observe the majority of the dots are clustered around 52, 55, 62, 65, and 67, indicating that these values are more common in Brand B than in Brand A.

Brand B has more dots in total than Brand A, suggesting that Brand B generally has more candy pieces per bag than Brand A..

Hence, the number of candies in the bags from Brand B is greater and less consistent than the number of candies in the bags from Brand A is valid statement.

Slope intercept form, y=mx+b, means that the line y, is represented by a slop m, and a y intercept b. So y=4x means that it has a slope of 4 and goes through the origin, since there is no y intercept.
