4x - 3y + 10 - x + 2y - 5

Simplify it!

Answers

Answer 1

Answer:

3x - y + 5

Step-by-step explanation:

4x - 3y + 10 - x + 2y - 5

To simplify, you need to combine like terms. Like terms are terms that have the same variable part. All terms with x are like terms and can be combined. All terms with y are like terms and can be combined. All terms with no variable are like terms and can be combined. A term with x and a term with y are not like terms and cannot be combined.

It may be helpful at first, to move the like terms together to combine them.

4x - 3y + 10 - x + 2y - 5 =

= 4x - x - 3y + 2y + 10 - 5

= 3x - y + 5

Answer 2

Answer:

3 x  −  y  +  5

Step-by-step explanation:

4x - 3y + 10 - x + 2y - 5

add/ subtract all the x values

4x - x = 3x

add/ subtract all y values

-3y + 2y = 1y or y

add/ subtract all real numbers

10 - 5 = 5

3x - y + 5

Imani spent half of her weekly allowance playing mini-golf. To earn more money her parents let her wash the car for $4. What is her weekly allowance if she ended with $12?

Answers

16 is her weekly allowence

Final answer:

Imani's weekly allowance is $16. This is determined by setting up and solving an algebraic equation based on the information provided in the problem.

Explanation:

Let's use the information given in the problem. The student, Imani, had an initial allowance. She spent half of it on mini-golf and then earned an extra $4 by washing a car. After these transactions, she has $12 remaining. We can use this to set up a simple algebraic equation.

Let x be the initial allowance. We know from the problem that Imani spent half of it, which is 0.5x, on mini-golf and earned an extra $4. So, the equation can be written as:

0.5x + $4 = $12

Solving this equation gives the weekly allowance. If we subtract $4 from both sides of the equation, we get 0.5x = $8. If we then divide each side by 0.5, we find that x = $16.

So, Imani's weekly allowance is $16.

Problem: A karate team had 6 girls and 9 boys. Then 2 more girls and 3 more boys joined the team. Did the ratio of girls to boys stay the same?Explain.

Answers

The answer would be yes. The way to solve this is by simplifying the first ratio. The first ratio should be girls to boys, which is 6:9. And since ratio can be fractions, 6:9 could be 6/9. Since 6/9 can simplify, you would get 2/3. Now we need to add the 2 girls and 3 boys back into the ratio. The ratio would then look like 8:12. And 8:12 could be 8/12, and 8/12 can be simplify, we get 2/3. So this means that the ratio stayed the same.

The ratio of girls to boys in the karate team remained the same at 2:3, both before and after the new members joined.

Initially, there were 6 girls and 9 boys, creating a ratio of 6 girls to 9 boys, which simplifies to 2:3 when divided by the greatest common divisor, 3. After 2 more girls and 3 more boys joined, the team had 8 girls and 12 boys.

This new ratio also simplifies to 2:3, since both the numerator and denominator can be divided by 4. Therefore, the ratio of girls to boys did not change after the new members joined the team; it remained the same at 2 girls for every 3 boys.

If the denominators of two fractions are the same, how do you add the fractions?

Answers

When you have the same denominator you can just add the numerators but not the denominator

For example:

[tex] \frac{3}{15} + \frac{5}{15} = \frac{8}{15} [/tex]

Step-by-step explanation: To add like fractions or fractions or fractions that have the same denominator, simply add the numerators and keep the original denominator.

Let's try an example.

[tex]\frac{1}{13}[/tex] + [tex]\frac{5}{13}[/tex] = ?

In this example, if we add the numerators we have 1 + 5 which gives us 6 and we put this over our original denominator which is 13. Therefore, 1/13 + 5/13 .  gives us 6/13 which is in lowest terms.

If kara lines up all 3/4 inch button what would be the total if the length?

Answers

Final answer:

To find out the total length of the buttons when lined up, multiply the number of buttons by the length of one button (3/4 inch). An expression for this would be L = n  imes (3/4). A button is considered pressed if the extended key length K* is greater than or equal to LO, the rest length of the lock.

Explanation:

If Kara lines up all her 3/4 inch buttons, the total length of the buttons aligned in a row can be found by multiplying the number of buttons by the length of one button. Let's denote the number of buttons as n, and the length of one button as 3/4 inches. Hence, the expression for the total length L would be L = n  imes (3/4) inches. If the key K* finally stops at a position that is greater than or equal to the rest length of the lock LO, then the button will be pressed.

To determine whether the button will be pressed, we could set up an inequality: K* \\geq LO. If this condition holds true, Kara knows that the button is pressed.

In a triangle the length of two sides are 1.9m and 0.7m. What is the length of the third side, if you know that it should be a whole number?

Answers

Answer:

2

Step-by-step explanation:

A side of a triangle is less than the sum of the lengths of the other two sides and is greater than the positive difference of them.

third side is in between 1.2 and 2.6 but it has to be a whole number so its 2

A possible measure of the third side is 2m (to the nearest whole number)

Using the triangular theorem which states that the measure of the third side of the triangle is less than the sum of the other two sides.

Given the length of the other two sides as 1.9m and 0.7m

Taking the sum

Sum of other two sides = 1.9m + 0.7mSum of other two sides = 2.6m

Since the length of the third side must e less than the sum, hence the required answer must be less than 2.6m.

A possible measure of the third side is 2m (to the nearest whole number)

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is ,

The y-value is ten decreased by the square of the x-value

So we have two variables x and y.

So square of x = x*x = x²

and, ten decreased by the square of the x-value = 10- x²

Hence we get y is 10- x²

write an equation for the line that passes through (5,-4) and is perpendicular to the graph of 5x -2y=-6

Answers

Answer:

y = (-2/5)x - 2

Step-by-step explanation:

One way to attack this problem is to interchange the coefficients of x and y and change the sign of one to +:  5x - 2y = -6 becomes 2x + 5y = c.  Solving for the slope, m, we get 5y = -2x + c first, and then y = (-2/5)x + D.

Subbing 5 for x and -4 for y, we now have -4 = (-2/5)(5) + D.

Then -4 = -2 + D, so that D = -2.

The desired equation is thus y = (-2/5)x - 2.

Check:  Does this pass through (5, -4)?  Is -4 = (-2/5)(5) - 2 true?  Yes.

Is the slope -2/5 the negative reciprocal of 5/2?  Yes, it is.

By substituting m=4 into each equation, we find that options A) 13 = 9 + m and E) 20 divided by m = 5 are the correct equations where m=4 is a solution.

Explanation:

In mathematics, specifically algebra, we can solve and check equations by plugging in values. You are asked to find the equations where m = 4 is a solution.

Let's substitute m with 4 in each equation:

A) 13 = 9 + m becomes 13 = 9 + 4. Hence, 13 = 13 which is true. B) 7- m = 3 becomes 7 - 4 = 3 so it is incorrect because 3 is not equal to 7 - 4. C) 15 = 11m becomes 15 = 44 which is incorrect. D) 5 = m + 2 becomes 5 = 4 + 2 which is incorrect because 5 is not equal to 6. E) 20 divided by m = 5 becomes 20 divided by 4 equal to 5. So, 5 = 5 is correct.

How can you tell from the graph of Molly's garden on the previous slide that it represents a proportional relationship?

Answers

Answer:

A proportional relationship is a relation of the form:

Y = A*X

This means that if we have two variables, X and Y, for each unit that X grows, Y grows A times that.

And notice that the relation:

Y/A = X

is also a porportional relationship

This relationship can be expresed in a graph as a straight line that pases through the origin and has a constant unit of growht (in this case A) that is also called the "slope" of the line.

The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
