Mathematics
1 answer:
nlexa [21]3 years ago
8 0

Answer:

The numbers are 17 and 5

Step-by-step explanation:

x + y = 22

x - y = 12

Add y to both sides of the equation

x = 12 + y

Substitute new value for x into first equation

12 + y + y = 22

Add the y's

12 + 2y = 22

Subtract 12 from both sides

2y = 10

y = 5

22 - 5 = 17

The numbers are 17 and 5

Hope this helps :)

5. Jon Metcalf signed a 253-day simple interest note for $7700 with a bank that uses exact interest. If the rate is 10 3/4% find
morpeh [17]

Answer:

8281.72

Step-by-step explanation:

Given:

Principal, P = 7700

Rate, r = 10 3/4 % = 43/4 % = 0.1075

Time, t = 253 days = 253/ 360

Using the relation :

A = P(1 + rt)

A = maturity value

A = 7700(1 + 0.1075*253/360)

A = 7700(1 + 0.0755486)

A = 7700(1.0755486)

A = 8281.7243

A = 8281.72

lukranit [14]
Tom ate 1/4 pizza, so that left him with 3/4 pizza. 

Now that 3/4 is divided into 1/12 , so now he got 3/4  : 1/12
 = 9 slices of 1/12 pizzas , or 9/12 of the original pizzas

Now it remained 1/6 or 2/12 of the original pizzas.

which mean, the amount of friends that got pizza are : 9 - 2 = 7 friends

hope this helps
