First you want to change all the "p"s to "4"s

It will look like "3 * 4 > 5 + 4"

Then you want to do the multiplication first and then the addition, although It doesn't really affect this problem.

12 > 9

So yes the given value is a solution.

So yes the given value is a solution.

Wouldn't it be 24? Because the range is the max-minimum=range. So the equation is x-16=8, which is x=24

This is the concept of sequences and series;

The sum of arithmetic series is given by:

Sn=n/2(2a+(n-1)d)

n=number of terms

a=1st term

d=common difference

From our sequence;

a=6, d=8, n=26

hence;

Sn=26/2(2*6+(26-1)8)

Sn=13(12+25*8)

Sn=13(12+200)

Sn=13(212)

Sn=2,756

The answer is 2,756

The sum of arithmetic series is given by:

Sn=n/2(2a+(n-1)d)

n=number of terms

a=1st term

d=common difference

From our sequence;

a=6, d=8, n=26

hence;

Sn=26/2(2*6+(26-1)8)

Sn=13(12+25*8)

Sn=13(12+200)

Sn=13(212)

Sn=2,756

The answer is 2,756

PEMDAS...parentheses, then exponents, then multiplication/division, finally addition/subtraction...

22+(3^2-4^2) inside the parentheses are exponents, so they are calculated first.

22+(9-16) now you complete the operations inside the parentheses

22+(-7) finally you do your addition/subtraction

C) is right

what you were probably doing wrong was subtracting the mean from the bigger number instead of subtracting the number from the mean. you also have to keep all of the numbers positive in the other mean set.

Center at (h,k) and radius r is

(x-h)²+(y-k)²=r²

so given

center at (9,-8)

(x-9)²+(y-(-8))²=r²

(x-9)²+(y+8)²=r²

input the point (19,22) to find r²

x=19 and y=22

(19-9)²+(22+8)²=r²

10²+30²=r²

100+900=r²

1000=r²

10√10=r

well, the equation is

(x-9)²+(y+8)²=1000

(x-h)²+(y-k)²=r²

so given

center at (9,-8)

(x-9)²+(y-(-8))²=r²

(x-9)²+(y+8)²=r²

input the point (19,22) to find r²

x=19 and y=22

(19-9)²+(22+8)²=r²

So the tire has a diameter of 22 inches, now the radius of that will he half the diameter, or 11inches

so, the circumference of it will be

how many revolutions.. on 600 feet, well, how many inches in 600 feet?

1ft is 12inches, so 600 * 12 is 7200 inches

now, one revolution is just a go-around the circle or 2π, a full circle

we know the circumference covered in a full circle with radius of 11, or diameter of 22, in a go-around is 22π

how many 22π are there in 7200 inches? well that many

QUESTION POSTED AT 16/10/2019 - 06:37 PM

**Answer:**

Henrique began to solve a system of linear equations using the linear combination method:

**Given the System of equation :**

....[1]

....[2]

**Multiply equation [1] by 3 to both sides we have;**

⇒ ....[3]

**Multiply equation [2] by -2 to both sides we have**;

⇒ ....[4]

Add equation [3] and [4] to eliminate x and solve for y:

**Divide both sides by -11 we have;**

**y = -2**

Substituting the value of y into equation [1] to solve for x.

⇒

**Subtract 14 from both sides we have;**

**Divide both sides by 4 we have;**

x = 3.5

**Therefore, the solution to the system is, (3.5, -2)**
