is (6,-7) a solution to y+3=1/2(x+2)

Answers

My answers are not 100% Valid but here is my answer and response;
Answer: (4,-2)
To get x substitute 0 for y since you’re trying to find x, 0+3=1/2(x+2) add 0 with 3 to get 3 so 3=1/2(x+2) then use distributive property with 1/2 (x•1/2 = x/2) (2•1/2 = 1) so then the equation would look like this 3=x/2+1 subtract one from both side and get 2=x/2 then multiply everything by 2 to get x=4
With y you can substitute 4 or 0 for x to find your answer

Tom earns $650 each week working his full-time job is employer has a 16.5% tax deduction and all monies earned each week calculate the tax deduction paid for that week​

Answers

Answer:

find 16.5% of 650 by turning 16.5 into a decimal.

subtract 104 from 650 and your approximate answer will be

$546

Tom paid $ 546 as tax deduction each week.

What is an Equation ?

An equation is a mathematical statement formed when an algebraic expression is equated by an equal sign by a constant or algebraic expression.

It is given that weekly earnings of Tom is $650

Tax deduction is 16.5%

Let the amount of Tax deduction is represented by $x

Then the equation formed is;

x = 16.5% 650

x = 16.5*650/100

x = $ 104

Now, subtract 104 from 650

$546

Therefore Tom paid $ 546 as tax deduction each week.

Step-by-step explanation:

I think because The United States allowed Japan to keep its emperor — Hirohito — after the war. Japan's post-war constitution became official on May 3, 1947, and Japanese citizens elected a new legislature. The U.S. and other allies signed a peace treaty in San Francisco formally ending the war in 1951.

According to Office Of The Historian," The outbreak of the Korean War in 1950 provided SCAP with just the opportunity it needed to address this problem, prompting some occupation officials to suggest that, “Korea came along and saved us.” After the UN entered the Korean War, Japan became the principal supply depot for UN forces. The conflict also placed Japan firmly within the confines of the U.S. defense perimeter in Asia, assuring the Japanese leadership that whatever the state of its military, no real threat would be made against Japanese soil."

Answer: Japan produced supplies for the United States during the Korean War.

Jorge is making 6 large salad and 4 small salads and 4 small salads. How many cherry tomatoes does he need ?. Large salad=10 cherry tomatoes. 4 small salads = 6 number of cherry tomatoes.​

Answers

I’m not sure if the scanning came out wrong but here’s 2 answers depending on what the question is;
1) Jorge makes 6 Large Salads and 8 Small Salads
The Large Salads contain 10 Cherry Tomatoes Each so just multiply 6 with 10
6•10=60 Cherry Tomatoes
The Small Salads contain 6 Cherry Tomatoes Each so just multiply 8 with 6
8•6=48 Cherry Tomatoes
Add both of the cherry tomato amounts to get 108 Cherry Tomatoes
Jorge needs 108 Cherry tomatoes to make his Salads.
2) Jorge makes 6 Large Salads and 4 Small Salads
In summary;
6•10=60 (Large Salads)
4•6=24 (Small Salads)
Add both to get the total
60+24=84
Jorge needs 84 Cherry Tomatoes to make his salads.

Mr. Barker saved his money for 47 years and had $3,700,028 in the bank. He used his money to go on an adventure and spent $967,300. How much did he have left after his adventure?

Answers

Answer:

The answer is $2,732,728

Step-by-step explanation:

You start subtracting by aligning the numbers by place value. You subtract and get 28 then you have to subtract 0 - 3 which you can’t do and next to it are 2 other 0’s the only number you can carry is 7. You cross out the 7 and put a 6 in its place. The zero next to it becomes a 9. The one next to it also becomes a 9. Then the one on top of the three becomes a 10. You then do 10 - 3. Which equals 7. Then you do 9 - 7 = 2. 9 - 6= 3. You can’t do 6 - 9. so you cross out the 3 make it a 2 and turn the 6 into a 16. 16 - 9 =7. 2 - 0 =2 so then you get. $2,732,728.
