Answer:
the last one
Step-by-step explanation:
there is a total of 80 items
34+24+10+11=80
= approx. 12.5% so a is wrong
= approx. 13.75% so b is wrong
there were 24 brownies sold and so c is incorrect
there were 10 cookies sold which does equal so the last one is right
Answer:
the unknown side of triangle is 15 in :)
Let's use the variable 'n' to represent the cost of a notebook and 'p' the cost of a pen.
If Kennel wants an equal number of notebooks and pens, we can create a group of one notebook and one pen, and the resulting cost will be 'n + p'
Then, to find the number of these groups Kennel can buy, we just need to divide the amount of money ($40) by the cost of the group of one notebook and one pen:
If the result is not a whole number, we need to round it down, since we can't spend more money than the budget of $40.
X^2 + 7^2 =14^2
x^2 +49 =196
x^2 -49 -49
x^2 = 147
x^2 / x^2
x = 147
