Mia bought 10 boxes of brownies at the store for a total of $64. The tax on the purchase was $5. What was the cost of each box?
Pavel [41]

Let r represent cost of each box.

We have been given that Mia bought 10 boxes of brownies. So cost of 10 boxes would be 10r.

We have been given that Mia bought 10 boxes of brownies at the store for a total of $64. The tax on the purchase was $5. So the total cost of 10 boxes would be cost of 10 boxes plus tax.

We can represent this information in an equation as:

10r=64+5

We can subtract 64 from both sides as:

10r-64=64-64+5

10r-64=5

Therefore, our required equation is 10r-64=5 and option 'c' is the correct choice.

What is the distance from the origin (0,0) to the point (34,-78)
pantera1 [17]

Given coordinates (0,0)  and (34,-78).

\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

We \ have\ x_1=0, x_2=34, y_1=0 \ and \ y_2=-78.

\mathrm{The\:distance\:between\:}\left(0,\:0\right)\mathrm{\:and\:}\left(34,\:-78\right)\mathrm{\:is\:}

=\sqrt{\left(34-0\right)^2+\left(-78-0\right)^2}

=2\sqrt{1810}

Distance = 2(42.544) ≈ 85.09.

Therefore, distance from the origin (0,0) to the point (34,-78) is 2\sqrt{1810} \ or 85.09 units.

Solve 2r ≤ 3(2r - 7)
Hoochie [10]
You have:
2r\leq6r-21
then move the 6r over to the left and you end up wtih
-4r\leq-21
Then you divide by -4 and when you do you must flip the inequality so your answer would be
r \geq21/4
