Harrizon [31]3 years ago
5 0
Estimate the quotient of 358 divided by 3. Let’s start estimating without using calculator. => 358 = 300 + 50 + 8 Let’s have the 300 first. How many 3s are there in 300 => 300 / 3 = 100 – so there are 100 3s Next, let’s have the 50. How many 3s are there in 50 => 50 / 3 = 16 remainder 2. So let’s go to the last number the 8 + 2 remainder = 10 => How many 3s are there in 10? => 10 / 3 = 3 remainder 1 => 100 + 16 + 3 = 119 remainder 1 let’s check => 119 * 3 = 357 + 1 = 358

A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solu
nlexa [21]

Step-by-step explanation:

If x = the amount of 12% and y = the amount of 20%, then x + y = 80

Since we need 80 grams of 15%, 80(.15) = 12.

We are given that .12x + .20y = 12.

We can solve the first equation for x or y. Let's do x.

x = 80 - y

.12(80 - y) + .20y = 12

9.6 - .12y + .20y = 12

.08y = 2.4

y = 30

x = 80 - 30 = 50

A rectangular garden has a walkway around it. The area of the garden is 6(6.5x + 2.5). The combined area of the garden and the w
Rasek [7]

According to the information given in the exercise, the following expression represents the area of the rectangular garden:

6\mleft(6.5x+2.5\mright)

And the following expression represents the combined area of the walkway around the rectangular garden and the area of the garden:

6.5\mleft(8x+6\mright)

You can identify that the word "combined" indicates that that expression was obtained by adding both areas.

Knowing the above, you can set up the following equation:

6(6.5x+2.5)+A=6.5(8x+6)

Where "A" is the area of the walkway around the rectangular garden.

Solving for "A", you get the following expression:

\begin{gathered} A=6.5(8x+6)-6(6.5x+2.5) \\ A=52x+39-39x-15 \\ A=13x+24 \end{gathered}

The answer is:

13x+24
