8, that is the same as saying what divided by 4 is 2, and 8 divided by 4 is 2. Thus, 2 is 1/4th of 8.

X*1/4=2
We then use the Symmetric Property of Equality and multiply both sides by 4/1.
X*1/4(4/1)=2(4/1)
X=8

Soloha48 [4]

A 5% raise means that you have to find out what 5% of 8 is and then add that to 8:

5/100 * 8 = 40/100 = $0.40

8 + 0.40 = $8.40.

Solve the following system of equations using matrices (row operations).

Stells [14]

Answer:

(6,3,0)

Step-by-step explanation:

Given,

x - y + 0z = 3

6x - 0y - 2z = 36

0x + 6y + 2z = 18

You have the following augmented matrix:

(1) 1 -1 0 3

(2) 6 0 -2 36

(3) 0 6 2 18

Let's (3) add to (2) and divide by 6

(1) 1 -1 0 3

(2) 1 1 0 9

(3) 0 6 2 18

Now, let's (2) add to (1) and divide by 2

(1) 1 0 0 6

(2) 1 1 0 9

(3) 0 6 2 18

Let's (3) ÷ 2

(1) 1 0 0 6

(2) 1 1 0 9

(3) 0 3 1 9

Let's (1) subtract from (2)

(1) 1 0 0 6

(2) 0 1 0 3

(3) 0 3 1 9

Finally, let's (2) multiply by 3 and subtract from (3)

(1) 1 0 0 6

(2) 0 1 0 3

(3) 0 0 1 0

Thus,

x = 6, y = 3 and z = 0

The answer is (6, 3, 0)

We have to verify the answer

6 - 3 = 3 ⇒⇒ 3 = 3

6*6 - 5*0 = 36 ⇒⇒ 36 = 36

6*3 + 2*0 = 18 ⇒⇒ 18 = 18

Mrs. Kim is teaching a 5th grade class. She is standing 48 feet in front of Lester. Carey is sitting to Lester's right. If Carey

victus00 [196]

Lester and Carey are 14 feet apart

Step-by-step explanation:

Mrs. Kim is teaching a 5th grade class

She is standing 48 feet in front of Lester
Carey is sitting to Lester's right
Carey and Mrs. Kim are 50 feet apart

We need to find how far apart Lester and Carey

Look to the attached figure

The positions of Mrs. Kim, Lester, and Carey formed a right triangle

∵ The distance between Mrs. Kim and Carey is 50 feet

∴ The length of the hypotenuse of the Δ = 50 feet

∵ The distance between Mrs. Kim and Lester is 48 feet

∴ The length of one leg of the Δ = 48 feet

The formula of length of the sides of the right Δ is:

$(hypotenuse)^{2}=(leg_{1})^{2}+(leg_{2})^{2}$

Substitute the length of the hypotenuse and the length of the given leg in the formula above

∵ (50)² = (48)² + (leg)²

∴ 2500 = 2304 + (leg)²

- Subtract 2304 from both sides

∴ 196 = (leg)²

- Take square for both sides

∴ 14 = leg

∵ This leg represents the distance between Lester and Carey

∴ The distance between Lester and Carey = 14 feet

Lester and Carey are 14 feet apart
