❌❌PLEASE HELPILL MARK BRAINLIEST❌❌❌Does coordinate m or coordinate n represent a greater number in the following parallelogram?
Maru [420]

Answer:

The answer would be m.

Step-by-step explanation:

The point would be (7,1)  If you look at the top two points, (3,5) and (10,5)  You can see that the y coordinates are the same.  They are both 5.  So on the bottom left (0,1) we know that are n will be 1 .  Now we have to figure out m.  If we look on the top (3,5) (10,5)  We can see from the x's 10 and 3, that they are a distance of 7 apart.  Since our bottom left hand corner is (0,1)  If we add 7 to 0 we get 7.  That makes m equal  7

jar contains 51 coins which are either quarters or nickels. total value of jar is 5.15. how many of each type of coin do they ha
docker41 [41]
I believe there are 20 quarters and 3 nickels.....

Total value of the jar is $5.15.....

Quarters are worth 25 cents
And nickels are worth 5 cents.

First you know that there are 4 quarters in a dollar.
 You have 5 dollars so you do 4 x 5 = 20

So five dollars ($5.00) is 20 quarters.
And you still have 15 cents left.

Because quarters are 25 cents the rest are nickels.

Nickels are worth 5 cents so you'd do 5 x 3 = 15.

15 cents!

Add all this together and get $5.15.

So your answer is 

There are 20 quarters and 3 nickels in the jar.

Twice a number is decreased by 7, and this quantity is multiplied by 3. the result is 9 less than 10 times the number. What is t
Lunna [17]

Answer:

(7-2x)3 =9-10x

x= -3

Step-by-step explanation:

we let the number to be x.

twice a number=2x is decreased by 7 that is to say 7-2x, is multiplied by 3, we have (7-2x)3.

the result is 9 less than 10times the number which is =9-10x.

so bringing all these together we have;

(7-2x)3=9-10x.

what is the number?

solving, we have:

(7-2x)3=9-10x

21-6x=9-10x

21-9= -10x+6x

12= -4x

dividing both sides by -4 we have our number

x= -3.

for proof we can substitute x=-3 into the equation.

21-6(-3) =9-10(-3)

21+18=9+30

39=39
