Answer:
4/6
Step-by-step explanation:
The probability of rolling a 6 is 1/6 as shown in the left section.
The probability of landing on tales is 1/2 as shown in the right section.
Becuase it is an or and not an and... you have to add them together.
1/6 + 1/2 = 1/6 + 3/6 = 4/6.
Therefore, the probability of rolling a 6 or landing on tails is 4/6.
Answer:
Step-by-step explanation:
Substitute 1 for x in each of your equations.
f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4
Then subtract g(x) from f(x):
3-(-4)
=7

Answer:
We can write proportion as:
Step-by-step explanation:
A cyclist rides at a constant speed, traveling 30 miles in 1.5 hours. Write a proportion that gives the number x of miles the cyclist rides in 4 hours
Proportion:
A proportion is used when two ratios are equal. It can be written as a/b=c/d
In our case we have:
a= 30 miles
b = 1.5 hours
c = x miles
d = 4 hours
We can write proportion as:
Answer:
BC = 9
Step-by-step explanation:
Given AC = 26
BC=7x + 2
AB = 9x + 8
Since BC and AB are two parts of AC. Therefore we can write in the following form.
AC = AB +BC
Now insert the given values in the above formula.
26 = 9x + 8 + 7x + 2
26 = 16x + 10
26 – 10 = 16x
16 = 16x
x = 16 / 16
x = 1
Now insert x = 1 in BC=7x + 2
BC = 7 (1) + 2
BC = 9
