If seven pencils cost $.84 find the cost of 10 pencils?
Lets solve this!
To solve this question, you need to first divide .84 ÷ 7 which gives you the answer 0.12. Then multiply 0.12 with 10 which gives you the cost of 10 pencils. 0.12 is the cost of only one pencil.
Lets forms this into statements ---
Cost of 7 pencils = $ .84
Cost of 1 pencil = $ 0.12
Cost of 10 pencil equals = .84 ÷ 7 = 0.12
= 0.12 × 10 = 1.2
Cost of 10 pencils is $1.2

Answer:
-4
Step-by-step explanation:
So since x=5 and y= 1 the new expression would be 1(5-7) to the second power. Using pemdas, 5-7 is -2. -2 to the second power is -4. negative 4 times 1 is negative 4.

Answer:$259
Step-by-step explanation:
since we need to increase $250 by 6%, it is useful to find one percent because 1% is easy to find
to find one percent of 250, we move the decimal point(we cant see it right now) from after the number to after 2 giving us 2.50. we need to do this to find one percent because 1% is the same as one HUNDREDth, and since 100 has two zeros, we move the decimal place two spaces.now that we know that 1% is $2.50 ( which is the same as $2.5) we can times that by six which gives us 6%(because one times 6 is 6) to multiply 2.5 by 6, we first multiply 6 by 2 which will give us 12 and then multiply it by 0.5 (because 2 + 0.5 =2.5) 0.5 multiplied by 6 is equal to 3 and 3 + 6 = 9. we know know that 6% of $250 is $9. we now just add 9 to 250 leaving us with $259
