Answer:

meat = $2.40

vegetables = $ 2.40

fruit = $2.40 + X

= 2.40 ÷ 2

= 1.2

therefore 2.40 + 1.2

=$3.6 (For fruits )

= $3.6 + $2.40 + $2.40

= $ 8.4

Hope this helps .Plzz mark me brainliest

The total cost of the meat, vegetables and fruit is $8.4.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the costs of the meat, vegetables and fruit are in the ratio meat : vegetables : fruit = 2:2:3.

The cost of the meat is $2.40.

Let the total cost of the meat, vegetables and fruit be x.

Now, 2+2+3=7

So, 2/7 ×x=2.40

2x=2.40×7

2x=16.8

x=8.4

Therefore, the total cost of the meat, vegetables and fruit is $8.4.

Answer:

-3/2

Step-by-step explanation:

The slope of a line is calculated by finding the rise over run of two points on the line. In this case, I use the points (-3, 4) and (1, -2). Then, I use the formula of [tex]\frac{y_{2} - y_{1}}{x_{2}- x_{1} }[/tex]  to find the slope. If 4 is [tex]y_{2}[/tex], -3 is [tex]x_{2}[/tex], 1 is [tex]x_{1}[/tex] and -2 is [tex]y_{1}[/tex], then,

[tex]\frac{4 - (-2)}{ -3- 1 } = \frac{6}{-4} = \frac{3}{-2}[/tex]

Furthermore, the slope of a parallel line is always the same as the given line. Therefore, the answer is -3/2.

Answer:

Option 4)  y - 1 = -2(x - 0)

Step-by-step explanation:

Given the slope, m = -2, and the y-intercept, (0, 1):

Substitute these values into the following point-slope form:

y - y1 = m(x - x1)

y - 1 = -2(x - 0)  ← This is the point-slope form given the slope, m = -2, and the y-intercept, (0, 1).

Therefore, the correct answer is Option 4: y - 1 = -2(x - 0)

Question 3:

O (9 x 80) + (9 x 1) 729

Step-by-step explanation:

Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1,  since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).

Answer:

Step-by-step explanation:

c - d = 7

c = 3 - 8i            Substitute into the top equation

3 - 8i - d = 7      Subtract 3 from both sides

- 8i - d = 7 - 3    Combine

-8i - d =4            Add 8i to both sides

-d = 4 + 8i           Multiply through by -1

-1*-d = -4 - 8i

d = - 4 - 8i

Answer:

x-intercept = 17/4 and y = -17/3

Step-by-step explanation:

To find the intercepts: set x = 0 for the y-intercept and solve the equation and set y =0 for the x- intercept and solve the equation.

To

4x - 3y = 17

4(0) - 3y = 17

0 - 3y = 17

  y = 17 /-3

 y = -17/3 = -5 2/3       y-intercept = -5 2/3.

The ordered pair on the graph is (0, -17/3)

   4x - 3(0) = 17

     4x - 0 = 17

      4x = 17

       x = 17/4       x-intercept = 17/4

    The ordered pair on the graph is (17/4, 0)

Answer:

You compare it by this

Step-by-step explanation:

Linear functions are graphed as straight lines while exponential functions are curved. Linear functions are typically in the form y = mx + b, which is used to discover the slope, or simply the change in y divided by the change in x, while exponential functions are typically in the form y = (1 + r) x.

Answer:

C = 8

Step-by-step explanation:

Rearrange the equation to make C the subject.

C - 12 = -4

Add 12 to both sides.

C - 12 + 12 = -4 + 12

C = -4 + 12

C = 8

Check it:

C = 8

So substitute the new found value into the original equation:

C - 12 = -4

8 - 12 = -4

-4 = -4

All good.

Answer:

C = 8

Hope this helps!

Step-by-step explanation:

C - 12 = -4

C - 12 + 12 = -4 + 12    ( Add both sides by 12 )

C = 8      ( Simplify )

Answer:

[tex] \frac{17}{40} [/tex]

Step-by-step explanation:

[tex] \frac{4}{5} - \frac{3}{8} [/tex]

First, find the common denominator

So we multiply 4 by 8, and get 32

Then we multiply 3 by 5, and get 15

Next we give both terms new denominators 5 × 8 =40

So now our fractions look like this:

[tex] \frac{32}{40} - \frac{15}{40} [/tex]

Now...that our denominators match we can simply

subtract the numerators

32 − 15 = 17

Thus the answer is:

Answer:

85

Step-by-step explanation:

20% x X = 17

20/100 x X = 17

X = 17 x 100/20

= 17 x 5

= 85

the number is 85

Answer:

17 is 20% of 85

Step-by-step explanation:

20%= 1/5 so 17 = 1/5 of that number if you multiple 17 by 5 that would equal 85.

17 is 20% of 85

Answer:

Inc Interest : $16,089

Step-by-step explanation:

1. Let's turn $50 a month into a year, so 50 * 12 = $600

2. Including the annual interest, which is $43.56 out of the $600

3. Add them together, which will be 43.56 + 600 = 643.56

4. Multiply it by 25 to get the full 25 years and you're done!

The value of Amy's investment after 25 years will be $140.75.

Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest. The straightforward crediting of cash flows related to an investment or deposit is referred to as "simple" interest.

Given that, Amy contributes $50 per month to the Lincoln National Bond Fund which earns 7.26% annual interest.

The investment after 25 years will be calculated as,

SI = ( P x R x T)/100

SI = ( 50 x 7.26 x 25 ) / 100

SI = $90.75

The total investment will be calculated as,

A = $90.75 = $50

A = $140.75

Therefore, the value of Amy's investment after 25 years will be $140.75.
