Can anyone solve this linear equation with elimination method? Please its important!

Answer:

(2x3) x 4= 2 (3x4)

Answer:

11.11%

Step-by-step explanation:

the increased price = 20-18 = $2

the percentage increased = 2/18 ×100%

= 11.11%

Answer: Percent increase = 11.11%

Concept:

Here, we need to know how to find the percentage of increase.

Percent increase is a measure of percent change, which is the extent to which something gains value.

Percent increase = [(final value - initial value) / initial value] × 100%

Solve:

Given information

Initial value = $18

Final value = $20

Given expression

Percent increase = [(final value - initial value) / initial value] × 100%

Substitute values into the expression

Percent increase = [(20 - 18) / 18] × 100%

Simplify values in the parentheses

Percent increase = [2 / 18] × 100%

SImplify by multiplication

Percent increase = 11.11 % (Rounded to the hundredth place)

Hope this helps!! :)

Answer:

1611.00

Step-by-step explanation:

You have $1611.00 in the account in 10 years. The correct option is B.

Interest that compounded continuously to the principal amount. This interest rate provides exponential growth to a period of time.

Formula of continuous compound interest rate;

F(t) = a(e[tex])^{rt}[/tex]

, where a is the principal amount, r is the interest rate and t is the time period.

Given:

You invest $800 into an annuity account that pays 7% annual interest, compounded continuously.

And the formula is given by:

F(t) = a(e[tex])^{rt}[/tex]

According to the question,

Investment a = $800

Time period = 10 years.

And the interest rate r = 7%

Converting interest rate into decimals,

r = 0.07

Substituting all the values top the formula,

F(t) = a(e[tex])^{rt}[/tex]

F(t) = (800)(e[tex])^{(0.07)(10)}[/tex]

F(t) = (800)(e[tex])^{(0.7)}[/tex]

F(t) = 1611

F(t) = $1611.00

Therefore, you have $1611.00 in account.

3) Complementary Angles

4) Vertical angles

Step-by-step explanation:

1st pair of angles are linear because they sum to 180 and are on the same line

2nd pair of angles are adjacent but not linear because they're not on a line

3rd pair of angles are complementary because they're neighboring a 90° angle and the three angles share the same line.

4th pair of angles are vertical because they're across from each other.

Answer:

Step-by-step explanation:

The lateral area of the regular pyramid shown in the diagram is 540 unit². Hence, option B is the right choice.

The area of a figure is the two-dimensional space enclosed within the boundary of that figure.

In the question, we are asked to find the lateral area of the regular pyramid shown.

A regular pyramid is one with all lateral faces the same.

In the given diagram, the pyramid shown has a hexagonal base. So it has 6 equal lateral faces.

Each lateral face is a triangle, with the base as 12 units and height as 15 units.

Thus, the area of one lateral face = (1/2)*12*15 units² = 90 units².

Thus, the total lateral surface area = Lateral surface area of one lateral face*number of lateral faces = 90 units²*6 = 540 units².

Thus, the lateral area of the regular pyramid shown in the diagram is 540 unit². Hence, option B is the right choice.

Answer:

To find this answer, you would need to find how many miles 1 gallon of gas will take them. To find this, you would do 290÷8=36.25. So with this information, you will be able to find out how much gas it would take to travel 400 miles. You would do 400÷36.25=11.03. 11.03 would be how many gallons of gas is used to travel 400 miles. Hope this helps! :)

3. x = 45

4. 73°

Step-by-step explanation:

3. The sum of the interior angles of a pentagon is 540° so

90° + 112° + 2x + (2x + 10) + 148° = 540°

Simplifying this, we get

4x + 360 = 540 => 4x = 180 or x = 45

4. The sum of the interior angles of a pentagon is 540° which means that the unknown interior angle is 107°. This angle is a supplementary angle to [tex]\angle{A}[/tex] so [tex]\angle{A}[/tex] is

180° - 107° = 73°.

Answer:

(3 ± √23 * i) /4

Step-by-step explanation:

To solve this, we can apply the Quadratic Equation.

In an equation of form ax²+bx+c = 0, we can solve for x by applying the Quadratic Equation, or x = (-b ± √(b²-4ac))/(2a)

Matching up values, a is what's multiplied by x², b is what's multiplied by x, and c is the constant, so a = 2, b = -3, and c = 4

Plugging these values into our equation, we get

x = (-b ± √(b²-4ac))/(2a)

x = (-(-3) ± √(3²-4(2)(4)))/(2(2))

= (3 ± √(9-32))/4

= (3 ± √(-23))/4

= (3 ± √23 * i) /4

Answer:

Jazmine must travel for the rest of the trip at 120km/hr.

Step-by-step explanation:

To find the speed for the latter half of the trip necessary to arrive on time, we can divide the remaining distance by the remaining time.

The remaining distance, in km, is found by subtracting the distance already covered, which is the product of the speed during the first part of the trip and the elapsed time during this part, from the total distance:

[tex]330-1.5\times60=330-90=240[/tex]

The remaining time, in hr, is found by subtracting the elapsed time during the first part from the total time limit:

[tex]3.5-1.5=2[/tex]

Therefore, the necessary speed in km/hr is:

[tex]\frac{240}2=120[/tex]

x - 6 is the equation, (unless there was a y, and it pasted wrong)

Step-by-step explanation:

You do additive property of equality by adding 1 to both sides.

-6x - 1 = 35

= -6x - 1 + 1 = 35 + 1

= -6x = 36

Division property of equality by dividing both sides by -6 or 6

= -6/-6x = 36/-6

= 1x = -6

x = -6

Answer:

5/6
