Step-by-step explanation:

For the first few exponents multiply and the rest they add because like terms.

The trick is that when you raise a power to a power you multiply. Otherwise you add if the base value is the same.

Step-by-step explanation:

(4 * 5) / 2 = 20 / 2 = 10

Answer:

Triangle R and triangle S are congruent triangles, so finding the area of triangle S would give us the area of triangle R.

The area of a triangle can be calculated as 1/2(bh), where b is the base and h is the height.

In this case, we have: 1/2(5)(4). This simplifies to 10.

So, the area of triangle R is 10 square meters.

Write a System of Equations to solve the following problem:

The county fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 13 vans and 2 buses with 211 students. High School B rented and filled 4 vans

and 4 buses with 268 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.

#students each VAN can carry:

#students each BUS can carry:

Answers

Answer:

each van carries 7 students

each bus carries 60 students

Step-by-step explanation:

let v = # students in a van

let b = # students in a bus

system of equations:

13v + 2b = 211

4v + 4b = 268

I multiplied the 1st equation by -2 to eliminate the 'b' terms

-26v - 4b = -422

+ 4v + 4b = 268

-22v = -154

v = 7

substitute '7' for 'v':

4(7) + 4b = 268

28 + 4b = 268

4b = 240

b = 60

Answer:

13v + 2b = 211

4v + 4b = 268

#students each VAN can carry: 7

#students each BUS can carry: 60

Step-by-step explanation:

Let v = number of students in each van.

Let b = number of students in each bus.

High School A:

13v + 2b = 211

High School B:

4v + 4b = 268

The system of equations is

13v + 2b = 211

4v + 4b = 268

We will solve this system of equation with the addition method.

Write the first equation as it is. Divide both sides of the first equation by 2 and write it below the first equation. Then add the equations.

13v + 2b = 211

(+) -2v - 2b = -134

----------------------------

11v = 77

Divide both sides by 11.

v = 7

Substitute 7 for v in the first original equation and solve for b.

13v + 2b = 211

13(7) + 2b = 211

91 + 2b = 211

Subtract 91 from both sides.

2b = 120

Divide both sides by 2.

b = 60

Answer:

13v + 2b = 211

4v + 4b = 268

Explanation:

The initial cost is $65.42

25% of 65.42 is 16.355

Add 16.355 + 65.42 and the total cost is: $81.78

The initial cost is $12.50

3.2% of 12.50 is 0.4

Add 0.4 + 12.50 and the total cost is: $12.90

A rectangle has length (x + 5)cm and width (x –2)cm. Its area is 60 cm 2

Answers

Area = length x width

60 = (x+5) (x-2)

60 = x^2 + 3x -10

Subtract 60 from both sides:

x^2 +3x -70 = 0

Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70

x = -10 and 7

Since the sides have to be a positive number we need to use 7

The length = x+5 = 7+5 = 12 cm

The width = x-2 = 7-2 = 5 cm

0=1-2y+14x what is the slope and the y-intercept

Answers

Answer:

slope: 7

y-intercept: 1/2

Step-by-step explanation:

Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).

[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]

So you know that m = 7, so the slope is 7

and

b = 1/2, so the y-intercept is 1/2.
