Let us say, the numbers are "a" and "b"
so their sum is 336, or
a + b = 336
and the first one is bigger than the second by 124
so... whatever "b" is, "a" is THAT plus 124, or
a = b + 124
thus one can say
a + b = 336
or
(b + 124) +b = 33
solve for "b"
what is "a"? well, a = b + 124
Step-by-step explanation:
this is how you solve it :)
Answer: True
Step-by-step explanation:
We try to keep the number greater than 1 and lower than 10, so between 1, and 9.
For example: 3545346 would be 3.5x10^6
you can see 3.5 is between 1 and 9
Answer: Dimes= 20, Nickels= 15
Step-by-step explanation:
Since we are looking for the amount of coins, we can use system of equations to solve for the amount of coins.
Equation 1:
0.1x+0.05y=2.75
This equation comes from the total cost. x stands for dimes and y stands for nickels. 0.1 is the worth of a dime and 0.05 is the worth of a nickel.
Equation 2:
x=2y-10
This equation comes from 10 less than twice the number of nickels.
We can use substitution to find x and y.
0.1(2y-10)+0.05y=2.75
0.2y-1+0.05y=2.75
0.25y-1=2.75
0.25y=3.75
y=15
There are 15 nickels.
Now that we have y, we can plug it back into the equation to find x.
x=2(15)-10
x=30-10
x=20
There are 20 dimes.
Answer:
The pizza that is a better deal is 12" square pan pizza for $3.95.
Step-by-step explanation:
This is because if you get 2 of the 12" square pan pizzas it will be 24" and you will only have to pay $7.90. but if you bought the 24" square pan pizza you would have to pay $14.95 which isnt a fair price.
