Answer:

Q1.Let's solve your equation step-by-step.

2(x+3)=5x+6−3x

Step 1: Simplify both sides of the equation.

2(x+3)=5x+6−3x

(2)(x)+(2)(3)=5x+6+−3x(Distribute)

2x+6=5x+6+−3x

2x+6=(5x+−3x)+(6)(Combine Like Terms)

2x+6=2x+6

Step 2: Subtract 2x from both sides.

2x+6−2x=2x+6−2x

6=6

Step 3: Subtract 6 from both sides.

6−6=6−6

0=0

Answer:

All real numbers are solutions.

Q2.x−3=2x−3−x

Step 1: Simplify both sides of the equation.

x−3=2x−3−x

x+−3=2x+−3+−x

x−3=(2x+−x)+(−3)(Combine Like Terms)

x−3=x+−3

x−3=x−3

Step 2: Subtract x from both sides.

x−3−x=x−3−x

−3=−3

Step 3: Add 3 to both sides.

−3+3=−3+3

0=0

Answer:

All real numbers are solutions.

Bally Manufacturing sent Intel Corporation an invoice for machinery with a $13,200 list price. Bally dated the invoice August 02

aliya0001 [1]

a. Based on the information the amount that Intel pay Bally on August 15 is $10,400.

b. The payable amount is $10,192.

a. Intel pay Bally on August 15:

First step is to calculate the 20% trade discount applied to gross invoice

20% trade discount applied to gross invoice =($13,200-$200) × 0.2

20% trade discount applied to gross invoice = $13,000×0.2

20% trade discount applied to gross invoice=$2,600

Second step is to calculate Net price after trade discount

Net price after trade discount = ($13,200-$200) - $2,600

Net price after trade discount =$13,000-$2,600

Net price after trade discount = $10,400

b. Payable amount:

Payable amount= $10,400-( $10,400×2%)

Payable amount=$10,400-$208

Payable amount=$10,192

Inconclusion the amount that Intel pay Bally on August 15 is $10,400 and the payable amount is $10,192.

Answer:

ARE ≅ ΔARC

By rule - SSS Congruence Postulate

Step-by-step explanation:

We are given that in the two triangles ARE and ARC.

Sides AE ≅ AC and RE ≅ RC

Moreover, they have AR as their common side.

<em>So, we get that, in ΔARE and ΔARC, all the three corresponding sides are equal.</em>

Thus, by the SSS Congruence Postulate, ΔARE ≅ ΔARC.

Act scores for the 1,171,460 members of the 2004 high school graduating class who took the test closely followed the normal dist

Alborosie

We can rewrite the asked question like this:
$E(X_1-X_2)$
wherein X_1 and X_2 are random variable with the same given normal distribution. Then mean of $(X_1-X_2)$ is zero and the variance
can be computed like this: $4.8+4.8=9.6$
So, the random variable $X_1-X_2$ follows a normal distribution
with means 0 and standard deviation 9.6.
The median of the law N(0,9.6) is 0.
So the expected difference of the score is 0.
