Mia can purchase a 40-ounce jar of peanut butter for $5.20 or a 15-ounce jar for $2.70. How much does Mia save per ounce by buying the 40-ounce jar? Pleaseeee help hurry in time.

Answer:

x = -5

Step-by-step explanation:

Since these two triangles are similar, the ratio between the corresponding lengths of each triangle will be the same.

This means the ratio between one side of each triangle (e.g. AD and DC) will be the same as the ratio between a different side of each triangle (e.g. BE and BC).

So, to create an equation for the sides which contain the unknown 'x', we must first find the ratio between the two sides by using a different set of sides.

On the right side we are given 9 for AD, and 18 for DC.

9/18 = 0.5

This means that the extra length of the larger triangle from the smaller one (AD) is half the length of the smaller triangle (DC). We can use this to make an equation for x:

If AD/DC = 0.5, then BE/EC will also = 0.5

BE = x+23

EC = x+41

Therefore:

[tex]\frac{x+23}{x+41} = 0.5[/tex]

Now we can solve by multiplying both sides by x+41 to eliminate the fraction:

[tex]x+23=0.5(x+41)[/tex]

Now we multiply out the brackets and move the terms to different sides:

[tex]x+23=0.5x+20.5[/tex]

[tex]0.5x = -2.5[/tex]

[tex]x = -5[/tex]

And if we substitute the -5 into the equations:

-5+23 = 18

-5 + 41 = 36

We will see that -5 does indeed give us the same ratio between the lengths:

18/36 = 0.5

Answer:

28 years

Step-by-step explanation:

youngest brother's age = x

middle brother's age = x+2

oldest brother's age = x+4

3(x-2) = (x+2)+48

[simplify]

3x-6 = x+50

[add 6 to each side]

3x = x+56

[subtract x from each side]

2x = 56

[divide each side by 2]

x = 28

Answer:

x can be 10 or -10

Step-by-step explanation:

combine like terms

-6<-1x

divide by negative 1 on both sides

flip the sign when dividing by a negative number

6>x is the answer.

Answer:

[tex]\boxed { x < 6}[/tex]

Step-by-step explanation:

Solve the following inequality:

[tex]-6 < 3x - 4x[/tex]

-Combine like terms:

[tex]-6 < 3x - 4x[/tex]

[tex]-6 < -x[/tex]

-Switch sides:

[tex]-6 < -x[/tex]

[tex]-x > -6[/tex]

-When you are dividing an integer by a negative integer, then the inequality sign would change. So, to get the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:

[tex]\frac{-x}{-1} > \frac{-6}{-x}[/tex]

[tex]\boxed { x < 6}[/tex]

Answer:

  5

Step-by-step explanation:

Put -2 where x is and do the arithmetic.

  f(x) = 2x² -3

  f(-2) = 2(-2)² -3 = 2(-2)(-2) -3 = 8 -3

  f(-2) = 5

Answer:

f(-2) = 5

Step-by-step explanation:

We just need to substitute x with -2 and simplify.

f(x) = 2x² - 3

f(-2) = 2(-2)² - 3

f(-2) = 2(4) - 3

f(-2) = 8 - 3

f(-2) = 5

Answer:

66.4°

Step-by-step explanation:

Let ∠XYZ be x°.

Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.

[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]

To find the value of x°, take the inverse of cosine.

[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]

Thus, ∠XYZ= 66.4°

*Given 2 sides, we can find the measure of an angle in a right- angled triangle by taking the inverse of the trigonometry function.

Answer: [tex]\frac{20}{24}[/tex]

Multiply each sides of the fraction (numerator/denominator) by 4.

5 x 4 = 20, 6 x 4 = 24

Make a fraction out of 20 and 24.

20/24 = [tex]\frac{20}{24}[/tex]

Make sure the fraction is correct, by adding.

20 + 24 = 44

Answer = 44

Step-by-step explanation:

Answer:

w = -8

Step-by-step explanation:

19 = -9w - 5 + 6w

19 = -3w - 5

19 + 5 = -3w

24 = - 3w

w = -8

Answer:

b = (4/6) - a/2

Step-by-step explanation:

6b + 3a = 4

6b = 4 - 3a

b. = (4 - 3a)/6

b. = (4/6) - a/2

The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

It is defined as the combination of constants and variables with mathematical operators.

In the provided expression, variable and constant are there

It is given that:

The equation in a and b, where a and b are the variables:

3a + 6b = 4

Here the indicated variable is b.

To find the value of b in terms of a make the subject as b:

Subtract 3a on both the sides in the equation 3a + 6b = 4:

The equation becomes:

3a + 6b -3a = 4 - 3a

6b = 4 - 3a

Divide by 6 on both sides:

The equation becomes:

6b/6 = (4 - 3a)/6

b = (4 - 3a)/6

Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Answer:

y = -5x + 4

Step-by-step explanation:

In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.

Answer:

y = -5x - 1

Step-by-step explanation:

Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.

Point slope formula = y - y = m(x - x)

m = -5    (-1, 4)

y - 4 = -5(x +1)

y - 4 = -5x - 5

y = -5x - 1

Answer:

7

Step-by-step explanation:

This function can never equal 0. Why? well here:

(f/g)(x) also just means [tex]\frac{f(x)}{g(x)}[/tex]. In this case, we get [tex]\frac{x^2-x-12}{x-4}[/tex] Or [tex]\frac{(x+3)(x-4)}{x-4}[/tex]. It seems like you can cancel out x-4 and bam, you get x+3 and any value should work.

However, x can never equal 4 because 4 leads to a case where you divide by 0. This is called discontinuity. Thus, the value you can't get is x=4, or 7 because when you plug 4 in, you get 0/0. Otherwise, any other real value is defined by x+3.
