1 (5) = 5
7/10(5/1) = 35/10
Simplify.
35/10 = 3 5/10 = 3 1/2
5 + 3 1/2 = 8 1/2
Lucas ran 8 1/2 miles in 5 days.
4 unknowns needs 4 equations. I'll call the unknown numbers a,b,c,d in that order left to right.
4 + a = b
a + b = c
b + c = d
c + d = 67
let's use substitution to get rid to combine equations and get rid of variables.
If a + b = c then a = c - b
4 + (c - b) = b
4 + c = 2b
If b + c = d then b = d - c
4 + c = 2(d - c)
4 + c = 2d - 2c
4 + 3c = 2d
then we have c + d = 67 so c = 67 - d
4 + 3(67 - d) = 2d
4 + 201 - 3d = 2d
205 = 5d
d = 41
Should be easy now, subtract backwards.
67 - 41 = 26
41 - 26 = 15
26 - 15 = 11
15 - 11 = 4
4, 11, 15, 26, 41, 67
Answer:
-3
Step-by-step explanation:
The common ratio of a geometric sequence is the number that each term of the sequence is multiplied by. This means that the the previous term is multiplied by the common ratio to get the current term. The common ratio can also be used to create a function that can predict future terms.
To find the common ratio of this sequence, divide a term by the previous term. For example, -15/5. This gives the answer, -3. Dividing the terms allows us to figure out what factor is being multiplied by in the sequence.
Answer:
it is A
Step-by-step explanation:
it has to be a because you cant have a negative chance at chosing something it would just be zero B.you have a 1.00 chance at chosing something C.you have a 1 oit of 100 chance at chosing something and D.you have a 1 out of 10 chance at chosing something
Start by taking the total number of golf balls, 360, and dividing it by how many golf balls come in each pack, to find the number of packs.
360 ÷ 24 = 15
So there are 15 packs, each with 3 yellow golf balls.
15 · 3 = 45
Meaning 45 of the golf balls would be yellow
