Answer:
4,374
Explanation:
Given the sequence: 2, 6, 18, ...
If we study the pattern we observe that:
This is a geometric sequence with:
• The first term, a=2
,• Common Ratio, r=3
The nth term of a geometric sequence is obtained using the formula:
Therefore, the 8th term will be:
The 8th term of the sequence is 4,374.
The <em><u>correct answer</u></em> is:
She can make 2 loaves of bread and 4 batches of muffins.
Explanation:
Let b represent bread and m represent muffins.
The equation for the amount of flour she needs is 3.5b+2.5m=17.
The equation for the amount of sugar she needs is 0.75b+0.75m=4.5.
To solve this, we will want to eliminate one of the variables. To do this, we will make the coefficients of one of the variables the same. If we multiply 2.5 by 0.3, we get 0.75; this is what we will do to the first equation:
She can bake two loaves of bread.
Substituting 2 for b in the first equation, we have
3.5(2)+2.5m=17
7+2.5m=17
Subtract 7 from each side:
7+2.5m-7=17-7
2.5m=10
Divide both sides by 2.5:
2.5m/2.5 = 10/2.5
m = 4
She can bake 4 batches of muffins.
