A child building a tower with Blocks uses 15 for the bottom row. Each row has 2 fewer blocks than the previous row. What formula would you use to find the number of blocks in the 5th row?
A)blocks in 5th row =15+(15-1)-2
B)blocks in 5th row=15+(5-1)(-2)
C)blocks in 5th row=15+(5+1)(-2)
D)blocks in 5th row=5+(15-1)(-2)
Answer:
B)blocks in 5th row=15+(5-1)(-2)
Step-by-step explanation:
We are given that
Number of block in bottom row=15
Each row has 2 fewer blocks than the previous row
We have to find the formula would you use to find the number of blocks in the 5th row.
Number of blocks in second row=15-2=[tex]15+1(-2)[/tex]
Number of blocks in third row=15-2-2=[tex]15+2(-2)[/tex]
Number of blocks in 4th row=[tex]15-2-2-2=15+3(-2)[/tex]
Number of blocks in 5th row=[tex]15-2-2-2-2=15+4(-2)[/tex]
Therefore, number of block in 5th row
[tex]15+(5-1)(-2)[/tex]
This is required formula to find the number of blocks in the 5th row
Hence, option B is true.
B)blocks in 5th row=15+(5-1)(-2)

How many pounds of green tea, worth $40 a pound, should be mixed with herbal tea, worth $50 a pound, to produce 20 pounds of blend worth $42 a pound?
Answer:
840
Step-by-step explanation:
First you have to multiply 42 by 20. Because you have to find the total cost of the whole bag. Then a little guess and check you would get 16 lb of green tea and 4 lb of herbal tea. They both have to equal 20 lbs and $840. Multiply 16 by 40 then 50 by 4 then add them together you will get 840.
Hope this was helpful.

Simplify each expression by using the distributive property and combining like terms.
3 ● (2x - 4) - 4x
Answer:
2x - 12
Step-by-step explanation:
Hello!
So, let's simplify using the distributive property.
Let's look at 3(2x - 4). You want to multiply 3 by every term inside the parentheses.
3*2x = 6x
3*-4= - 12
So now our expression looks like this:
(6x - 12) - 4x
Now we combine like terms. Our only like terms are 6x and -4x.
6x - 4x = 2x. So, our simplified expression is:
2x - 12.
