Answer:
22a + 12b
Step-by-step explanation:
First, you should combine like terms. Like terms are when numbers have the same variable, such as the variable 'a'.
26a and -4a both have 'a' as their variable. To combine them, add -4a to 26a. You should get 22a as your final result.
The other two numbers in this equation that share a common variable are 2b and 10b. To combine these, all you have to do is add them together. After adding these two, you should get 12b.
After combining all like terms, there is none left, meaning you can't combine 22a and 12b since they don't share the same variable.
Answer:
Step-by-step explanation:
p(b)=3/12 = 0.25
p(r)=5/12 = 0.42
p(w)=4/12 = 0.33
p(¬r) = 1-0.42 = 0.58
p(¬w)= 1-p(w) = 0.67
P(not red Inot white)= 0.58/0.67=0.87
Answer:
Part 1)
Part 2) There are about
Step-by-step explanation:
Part 1) we know that
1 month=4 weeks
Let
x------> the number of hours of practice for three months
so
Convert months to weeks
3 months=3(4)=12 weeks
using proportion
that means------> In three months (12 weeks) the pianist practice 180 hours
Part 2)
Let
x------> the number of bass
y------> the number of catfish
we know that
Using proportion
There are about
Answer:
y=2x-14
Step-by-step explanation:
y=mx+b(m is slope)
we know
y=2x+b
so if you plug in the values for the points you get
-6=4(2)+b
-6=8+b
b=-14
so then the complete equation would be
y=2x-14
AC is 20 and m of angle EBC is 65 if ABC is 130.
