Evaluate the expression 2.1x - 4.3 for x = 2.2.

Answer: 387 1/2 miles

Step-by-step explanation:

From the question, we know that 20 gallons can be used for 500 miles. Therefore, the gallons of gas per mile will be:

= 500/20

= 25 gallons per mile.

The number of miles that a 15 1/2 gallons will use will be:

= 25 × 15 1/2

= 387 1/2 miles

Answer:

7 by 24 of barbecue items would be considered as mushroom caps

Step-by-step explanation:

The fraction of barbecue items considered as mushroom caps is given below:

Let us assume the number of barbecue items be x

So,

x = Veggies burgers of barbecue + corn cobs of barbecue + mushroom caps of barbecue

Now

Veggies burgers of barbecue = (3 ÷ 8)x

corn cobs of barbecue = (1 ÷ 3)x

And, we assume the mushroom caps of barbecue be y

Now the equation would be  

x = (3 ÷ 8)x + (1 ÷ 3)x + y

Now multiplied by 24 to both the sides  

24x = 9x + 8x + 24y

24x = 17x + 24y

24y = 24x - 17x

24y = 7x

y = (7 ÷ 24)x

This means that 7 by 24 of barbecue items would be considered as mushroom caps

Answer:

Y= 5/6x+5

Step-by-step explanation:

Okay same as before

the slope is rise over run

The rise is 5

The run is 6

So 5/6

And since ts rising from left to right its positive

The y-intercept which is the first point the line touches the Y axis is 5

So y=5/6x+5

Answer:

Step-by-step explanation:

1= 2/3

2=5/6

3=21/40

4= 2 11/20

5= 1 1/3

6=5/6

7=1 1/2

8=9/10

9= 5 1/6

10= 2 1/2

Answer:

Quadrant 1

Step-by-step explanation:

Since a and b are both greater than zero and are real numbers, they are both positive. The only quadrant that can contain a point with positive values for both x and y is Quadrant 1.

Answer:

91%

Step-by-step explanation:

If the total is 34, she spent 31/34 dollars on shorts. Divide this and you get 0.91

To make this a percent, move the decimal two places to the right (multiply by 100). Your final answer is 91%

Answer:

14.8 pounds

Step-by-step explanation:

Here, we want to get the actual value made of fat from the body weight

What we have to do here is to multiply the percentage by the body weight

Mathematically, we have this as;

18.8% of 127 pounds

= 18.8/100 * 127 = 14.80 pounds

Answer:

a/6

Step-by-step explanation:

Hannah has a total of "a" stickers.

Then, she divides the stickers into 6 envelopes, we can think of the envelopes as "groups".

This is what is called a quotient, and it is written as:

a/6

This is the number of groups of 6 elements of a, and in this case, represents the number of stickers that we will have in each one of the 6 envelopes.

Answer its rhombus

Step-by-step explanation: i took the test

The quadrilateral formed by the taping together of two equilateral

triangles is a rhombus.

The given types of triangles that form the quadrilateral are equilateral

triangles.

Given that the triangles have congruent side lengths, we have;

1) The side lengths of the quadrilateral formed are equal.

2) A pair opposite angles of the quadrilateral formed are equal to the interior angle of an equilateral triangle which is 60°.

3) The other pair of opposite angles are also equal to 60° + 60° = 120°.

The altitude of an equilateral triangle is perpendicular to the base.

Which gives;

4) The diagonals bisect each other at right angles.

Therefore;

The adjacent angles are supplementary

Which gives;

5) The opposite sides are parallel.

The above properties are the properties of a rhombus

Therefore;

Answer:

$4026.52

Step-by-step explanation:

Given data

rate= 5%

time= 3years

A=$4630.50

P=?

we know that

A=P(1+rt)

$4630.50=P(1+0.05*3)

$4630.50=P(1+0.15)

$4630.50=P(1.15)

P=4630.50/1.15

P=$4026.52

The intitial amount is $4026.52

When you divide fractions, you have to "multiply fraction's" by the reciprocal. In order to solve a division-fraction problem you have to use KCF. (Keep, Change, Flip)
