So 3 times 3 means 9 (times tables) or
3 of 3 or 3+3+3 or 9
so f5 times 5 means (f)(5)(5) associative property of multiplication says (ab)c=a(bc) so
(f)(5)(5)=f25 or 25f
9189 divided by 3 times 7^2
pemdas
parenthasees exponents mult/division whicherver comes first, addition/subtraction whicherver comes first
so 7^2 is first
7^2=7 times 7=49 (times tables)
then division
9189/3=3063
then 3063 times 49= (use calculator) 150,087
Answer:
y=x-2
y=x+5
Step-by-step explanation:
I wasnt sure if u wanted me to solve for x but I did anyway so there u go if thats what answer u want
Answer:
27720
Step-by-step explanation:
Denote by the binomial coefficient "n choose k". Given k<n, is the number of ways of choosing k elements from a set of n elements (the order in which we choose the elements doesn't matter).
First, we can form the group of 3 students. This is done by choosing 3 students from the class of 12 students, so it can be done in ways. We can't repeat students, then we must form the other groups from the remaining 9 students. If we next form the group of 4 students, there are ways of choosing it. Now, there remain 5 students without a group, so they have to conform the group of 5 and this can only be done in 1 way. By the multiplication principle, the number of ways of forming the groups is
R=number of hours ruby worked
i=number of hours issac worked
s=number of hours shetland worked
ruby worked 8 more than issac
r=8+i
shetland worked 4 times as many as ruby
s=4r
total they worked 136
r+i+s=136
so
we gots
r=8+i
s=4r
for r=8+i
solve for i
minus 8 both sides
r-8=i
so
r+i+s=136
subsitute r-8 for i and 4r for s
r+r-8+4r=136
6r-8=136
add 8 to both sides
6r=144
divide both sides by 6
r=24
sub back
r-8=i
24-8=i
16=i
s=4r
s=4(24)
s=96
ruby worked 24 hours
issac worked 16 hours
shetland worked 96 hours
The correct answer is 35 degrees
