2(5b-7), you can input b as 3y
2(5(3y)-7) —> 2(15y-7) —> 30y -14
—> 30y = 14 —> y = 14/30 —> y = 4.6667
So, we need to consider what is being done.
So, lets start with the -3.
-3*
Now, lets see what's next
2 times a number is the same as saying 2x, then add one.
That is equal to five.
-3(-2x+1)=5
Now,
6x-3 = 5
6x = 8
x= 8/6
There is no graph in your question. If p is number of reams of paper, and c is number of ink cartridges, then
3p + c = 234, wich p and c natural numbers (including 0)
This means that 13 ink cartridges and 0 paper will satisfy the end amount, but also 0 ink cartridges and 39 paper. There are 14 combinations possible.
To find a percentage of a number, multiply by the decimal form of that percentage(20%=0.20). So, take the cost, $430, and multiply by common state sales tax (7% for me)---430 x 0.07 = 30.10 The sale tax rate is 7%.
Answer:
I would go with c.
Step-by-step explanation:
