Answer:
7 miles
Step-by-step explanation:
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered
Answer:
2x=10
Step-by-step explanation:
7x-14=21
x=5
2x=10 (divide both sides by two)
2x/2 10/2
<u>x=5</u>
For a system to have no solution the equations would need to be parallel. Lines are parallel when they’re slopes are the same which can only be said for graph b
Graph B is the correct answer
For this question, the order of the paintings matter, so we can use generic permutation formula.
P = n!/(n-r)!
where:
n= number of paintings
r = number of paintings we are picking (in this case, we are selecting all paintings, as we are rearranging the paintings)
P = 4!/(4-4)!
P = 24/0! = 24 ways
4 paintings can be arranged in 24 different ways.
