One way is to factor and see which ones repeat
125=5*5*5
it is 5 times itself 3 times
5^3
Answer:
Nw how old is the girl, her mum & her dad?
let x=xmum's age
x+5=dad's age
x/2 =girl's age
x+x+5+x/2=100
3.5x=95
xmum's age=38
dad's age=43
girl's age=19
Answer:
the best estimate for each boc cost is $15
Step-by-step explanation:
divide 305 to 21 it is near 15
Distribute 7 to both n and 1
7(n + 1) = 7n + 7
5n + 7 = 7n + 7 - 2n
Combine like terms
5n + 7 = 7n - 2n + 7
5n + 7 = 5n + 7
If you want to solve for n, subtract 7 from both sides
5n + 7 (-7) = 5n + 7 (-7)
5n = 5n
then divide 5 from both sides
5n/5 = 5n/5
n = n
Effectively, this equation is <em>unsolvable</em>
hope this helps
Answer
I think that c would equal 4
Step-by-step explanation:
If you need the explanation, here it is:
When looking at the y part of the answer, you can see it goes up by three and that it is missing a point. This means that if the equation is linear, it goes up by one. Hope that's right!!
