16 is her weekly allowence

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.

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.

0.2(6x+1)/3.6=0.5x/9

We move all terms to the left:

0.2(6x+1)/3.6-(0.5x/9)=0

We add all the numbers together, and all the variables

0.2(6x+1)/3.6-(+0.5x/9)=0

We get rid of parentheses

0.2(6x+1)/3.6-0.5x/9=0

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.

Answer: 9 green peppers and 3 red peppers

Step-by-step explanation:

Lupe makes 12 servings:

She uses 12 green peppers and 4 red peppers.

If you want to know the number of each pepper that she needs for servings, you must divide the number of peppers by the number of servings:

green : 12/12 = 1

She needs one green pepper for serving:

red: 4/12 = 1/3

She needs one third of a red pepper for serving, so for 9 servings she needs:

9*1 = 9 green peppers

9*(1/3) = 9/3 = 3 red peppers

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

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)

Answer:B

Step-by-step explanation:

The step by step solution us given in attachment below.

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.

a = [tex]\sqrt{\frac{4d}{bc} }[/tex]

isolate the term in a

[tex]\frac{1}{4}[/tex] a²bc = d ( multiply both sides by 4 to eliminate the fraction )

a²bc = 4d ( divide both sides by bc )

a² = [tex]\frac{4d}{bc}[/tex]

Take the square root of both sides

a = [tex]\sqrt{\frac{4d}{bc} }[/tex]

Answer:

A, B, E

Step-by-step explanation:

A) 13=9+m

m= 13-9

m=4 ✔️

B) 7-m =3

m= 7-3

m=4 ✔️

C) 15= 11m

15=11*4

15≠44

D) 5= m+2

If m=4 therefore

5≠4+2

5≠6

E) 20 divide m = 5

20/4 = 5

therefore, m=4 ✔️

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.

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:

Therefore, the equations where m=4 is a solution are A) 13 = 9 + m and E) 20 divided by m = 5.

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.

Complementary angles equal 90 degrees.

Since each corner of the rectangle equals 90 degrees, the answer needs the same letter in the middle of each angle.

answer:

y = 10 - x²

step-by-step explanation:

the y value is means the y value is equal to meaning the first part of our equation is y =

10 decreased means 10 minus so the next part of our equation is y = 10 -

the square of the x value means x squared so the last part of our equation is y = 10 - x²

The required expression is y =  10- x²

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

So the expression is

y =  10- x²

Hence,the required expression is y = 10- x²

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.

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.
