1: learn to spell
2: you put it in the wrong category so no one here can help you
Step-by-step explanation:
So the equaiton is
number of nickes=n
number of quarters=q
if you have 1 quarter then you have 25 cents so we will represent like this
25q
and nickles is 5n
14.50=1450 cents
so
25q+5n=1480
q+n=88
subtract q from both sides
n=88-q
subsitute into first equation
25q+5(88-q)=1480
25q+440-5q=1480
add like terms
20q+440=1480
subtract 440 from both sides
20q=1040
divide both sdies by 20
q=52
there were 52 quarters
25(52)+5n=1480
1300+5n=1480
subtract 1300 from both sides
5n=180
divide both sides by 5
n=36
there were 36 nickels
nickles=36
quarters=52
Answer:
12
Step-by-step explanation:
5(x-6)=2(x+3)
multiply
5*x and 5*6. 2*x and 2*3
5x-30=2x+6
minus 5x and 2x
3x-30=6
add 30 to 6
3x=36
divide both sides by 3 and the 3x cancels so 36÷3
x=12
|-5| - |7 - 4|
First, simplify |-5| to 5. / Your problem should look like: 5 - |7 - 4|
Second, simplify 7 - 4 to 3. / Your problem should look like: 5 - |3|
Third, simplify. / Your problem should look like: 2
Answer: 2
Median would be 8.. not sure about the mode though considering there are no repeating numbers..
