PLEASE HELP !!!! SYSTEMS OF EQUATIONS

In the student government election, Maddie received 20% more votes than her opponent. A total of 1,485 votes were cast for both candidates. How many votes did Maddie receive?

Answers

Answer 1

Answer:

Maddie got 810 votes

Step-by-step explanation:

We'll call Maddie's votes x, and her opponent's votes y.

x + y = 1485

x = y + 0.20y (because she got the same number of votes as her opponent, PLUS another 20% of that number. Divide 20% by 100 to get the decimal equivalent) This can also be written as x = 1.2y

So our system is

x + y = 1485   and

x = 1.2y

Substitute the second equation's value for x into the first equation:

1.2y + y = 1485 then solve for y

2.2y = 1485

divide both sides by 2.2

y = 675

substitute that in and solve for x

x + y =1485

x + 675 = 1485

subtract 675 from both sides

x = 810

Please let me know if you have questions on this answer. Hope it helps.

b) (19+7/2)-5

[tex]( \frac{19 + 7}{2} ) - 5[/tex]

hope this answer helps you dear...

Hi !
A
19 + 7 / 2 - 5
According to PEMDAS, division comes first, so we start by diving 7 by 2, which equals 3.5.
19 + 3.5 - 5 = 17.5

B
19 + 7 / 2 - 5
In order for this to equal 8, the brackets will be placed like this: (19 + 7)/2 - 5
It gives (26)/2 - 5
Then we divide 26 by 2 (according to PEMDAS once again)
We get 13 - 5 = 8

C
19 + 7 / 2 x 6 + 1
In order to get 2 as an answer, we place the brackets this way:
(19 + 7)/(2 x 6 + 1)
(26)/(12 + 1)
26/13 = 2

Answers

Answer with Step-by-step explanation:

a) 2 3/4 ÷ 3 = 11/12 feet

11/12 + 11/12 = 1 5/6

Or, you could write an algebraic equation:

 2 3/4 ÷ 3 = x.  (3x = 2 3/4)

x = 11/12

The height of the brick proportion of the wall is 1 5/6

b)

You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.

So, your rounded answer should be 16. Or 16 1/2

c)  

Area = 8 1/2 x 2 3/4.

Use Distributive Property to solve the area.

(8 x 2) + (3/4 x 1/2) = x

8 x 2 = 16

3/4 x 1/2 = 3/8

16 + 3/8 = 16 3/8

x = 16 3/8

I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

You can buy 5 cans for green beans at the Village Market for $2.70. You can buy 10
of the same cans of beans at Sam's Club for $6.50. Which place is the better buy?

Answers

Answer:

Village Market

Step-by-step explanation:

for this question we need to find the unit rate (the rate for one of something).

in this case, we need to find the cost of one can at each store so we can

easily compare the cost to see which one is cheaper

it would be (total cost)/(total number of cans)

Village Market = $2.7/5 = .54 cents per can

Sam's Club = $6.5/10 = .65 cents per can

Since Village Market has a cheaper price per can, it is the better buy.

Answer:

Village Market

Step-by-step explanation:

10 cans at the Village Market is = to $5.40.

But at Sam's Club 10 cans cost $6.50 witch is $1.10 more money your paying when u can save it.
