If your car can drive 433 miles on a full tank of gas, find the miles per gallon if your gas tank holds 17.2 gallons? How much does it cost to fill your tank if gas is $2.85 per gallon?

Answers

Answer:

-25.17 miles per gallon.

-It costs $49.02 to fill your tank.

Step-by-step explanation:

-To find the miles per gallon, you can use a rule of three:

17.2 gallons →  433 miles

    1 gallon   →        x

x=(1*433)/17.2= 25.17

If your gas tank holds 17.2 gallons, you car can drive 25.17 miles per gallon.

-To find the cost to fill your tank, you have to multiply the price per gallon for the amount of gallons that the tank can hold:

$2.85*17.2=$49.02

It costs $49.02 to fill your tank.

What is the solution to 4x-8=12 please explain.

Answers

Answer:

x=5

Step-by-step explanation:

4x−8=12

Step 1: Add 8 to both sides.

4x−8+8=12+8

4x=20

Step 2: Divide both sides by 4.

4x

4

=

20

4

x=5

Answer:

One solution, x=5.

Step-by-step explanation:

4x-8=12

To find the solution we have to find the value of x.

to find the value of x, we have to add 8 to BOTH sides.

4x-8=12   (Why add 8? because we have to do the opposite of the sign!)

   +8  +8

4x=20

Now to find X we have to ISOLATE IT.

So we take out 4, How? We do the opposite to both sides.

4/4 Cancels out

20/4 = 5

So now we know X=5

Insert in the main problem to check.

4(5)-8=12

20-8=12

12=12

Oscar has received a $4,000 gift and is looking for a bank to start a savings account. Which option would be the best for him at a current inflation rate of 1.5%?

Answers

Here is the complete question

A nominal interest rate of 5%

A real interest rate of 5%

A real interest rate of 3%

A nominal interest rate of 3%

Answer:

A real interest rate of 5%

Step-by-step explanation:

A real interest rate of 5% is the best option for oscar. The nominal rate of interest is a type of interest rate that shows the increase in in percentage of money without the depreciation discount that is usually caused by inflation or the payment of tax.

The real rate of interest shows the real increase in the money that has been paid for an investment. This is after inflation has been discounted and all forms of taxes have been paid.

So oscar should invest his $4000 on a savings account whose real interest rate is 5% per year

Write a paragraph proving that x=8 in the equation 7x-28=28

Answers

Answer:

[see below]

Step-by-step explanation:

We would need to undo the equation and preform inverse operations to get 'x' on one side. First, we need to get rid of 28 by adding 28 to each side. This would leave us with 7x on one side. Then, we wound divide each side by 7. This would leave us with 'x = 8'. If we plugged in the value, then it would satisfy the equation.

[tex]7x-28=28\\\\7x-28+28=28+28\\\\7x=56\\\\\frac{7x=56}{7}\\\\ \boxed{x=8}[/tex]

7|12x+3|- 1=62 hhih​

Answers

Answer:

a. x = ½, and x = -1

Step-by-step explanation:

Given the equation, 7|12x + 3| - 1 = 62, solve as follows:

Add 1 to each side of the equation

7|12x + 3| = 62 + 1

7|12x + 3| = 63

Remove the absolute value to create ± on the right side of the equation

7(12x + 3) = ±63

Solve the positive portion of the solution

7(12x + 3) = 63

84x + 21 = 63

Subtract 21 from both sides

84x = 63 - 21

84x = 42

Divide both sides by 84

x = 42/84

x = ½

Solve the negative portion of the solution

7(12x + 3) = -63

84x + 21 = -63

Subtract 21 from each side of the equation

84x = -63 - 21

84x = -84

Divide both sides by 84

x = -84/84

x = -1

The answer is: x = ½, and x = -1

Point T is on line segment SU. Given ST = 2x + 6, TU = 4, and SU = 4x, determine the numerical length of ST

Answers

Step-by-step explanation:

Point T is between Points S and U, where all 3 points are collinear.

Therefore ST + TU must be equal to SU.

(2x + 6) + 4 = 4x

2x + 10 = 4x

2x = 10

x = 5.

Hence, length of ST = 2(5) + 6 = 16.

The length of ST will be 16 units.

What is a line segment ?

A line segment is basically a line with two end points.

two or more than two co-linear points is needed to form a line segment.

In the given question

Line segment is SU

Point T is in between point S and point U here all the points are co-linear

SU = ST + TU

4x = (2x + 6) + 4

4x = 2x + 10

2x = 10

x = 5

∴ The length of  ST = 2x + 6 = (2×5) + 6 = 16 units

Camilla has twice as many blueberry jelly beans as cherry jelly beans. After eating 10 pieces of each kind, she now haas three times as many blueberry jelly beans as cherry jelly beans. How many blueberry jelly beans did she originally have?

Answers

Answer:

40 blueberry jelly beans

Step-by-step explanation:

Let us represent blue berry beans = b

Cherry jelly beans = c

Camilla has twice as many blueberry jelly beans as cherry jelly beans.

Hence,

b = 2c .........Equation 1

After eating 10 pieces of each kind, she now has three times as many blueberry jelly beans as cherry jelly beans.

hence,

b - 10 = 3(c - 10)

b - 10 = 3c - 30

Collect like terms.

- 10 + 30 = 3c - b

20 = 3c - b .........Equation 2

Subtitute 2c for b in Equation 2

20 = 3c - 2c

20 = c

Hence, she had 20 cherry jelly beans.

In the question, we are asked to find how many blueberry jelly beans she had.

Hence,

b = 2c .........Equation 1

Substituting 20 for c in Equation 1

b = 2 × 20

b = 40

Therefore, she originally had 40 blueberry jelly beans

Step-by-step explanation:

There are four  3's

[tex]3\times 3\times3\times3 = 81\\\\3^4 = 81[/tex]

Answer: 3⁴

Explanation: Exponential form contains a base and an exponent.

The base is the number that is multiplied.

So in this case, 3 is the base.

Next we write the exponent which is the

number of times that the base is multiplied.

Since 3 is multiplied four times, the exponent is 4.

So in exponential form, 3 · 3 · 3 · 3 can be written as 3⁴.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

If we want to know whether a point is a solution to the equation or not, substitute it in the line and check whether both sides of the equation are equal or not.

Points N and K are on a plane A and plane S ( True )

Points P and M are on a plane B and plane S

Point P is the intersection of line n and line g ( True )

Points M, P, and Q are noncollinear ( True )

Line d intersects plane A at point N.

Step-by-step explanation:

The true are 1, 3, 4 and false are 2, 5.

To choose the statement are true or false.

What is plane?

A surface in which if any two points are chosen a straight line joining them lies completely in that surface. A plane is a flat, two-dimensional surface that prolongs infinitely far.

Given that:

1. Points N and K are on plane A and plane S.

From  that points N and K are on the plane A and on the plane S. Thus, this option is true.

2. Points P and M are on plane B and plane S.

From points P and M are on the plane B, but point M doesn't lie on the plane S. So, this option is false.

3. Point P is the intersection of line n and line g.

Point P lies on the line n as well as on the line g, therefore it is the point of intersection of these two lines. This option is true.

4. Points M, P, and Q are noncollinear.

It is true, because points M, P and Q do not lie on the same line at one time, that means they are noncollinear.

5. Line d intersects plane A at point N.

From the line d intersects plane S at point L, not at point N, then this option is false.
