A box of chalk and 2 staplers cost $10. three boxes of chalk and 2 staplers cost $18. find the total cost of 1 box of chalk and

Alchen [17]

Here is the solution of the given problem above:
Let s= staples
<span>c = chalk</span>

<span>c + 2s = 10 </span>
<span>3c + 2s = 18 </span>

<span>-c-2s = -10 </span>
<span>3c + 2s = 18 </span>

<span>2c = 8 </span>

<span>c = 4 </span>
<span>s = 3
</span>Therefore, the price per chalk box is $4 and per stapler is $3.
So the total cost of the chalk and stapler would be $7.
Hope this is the answer that you are looking for. Thanks for posting it here in brainly.

Solve the following equations. Round your answers to the nearest hundredth as needed.

Mekhanik [1.2K]

Answer:

b = 1.31

Step-by-step explanation:

Step 1: Add 1.93 to both sides.

$9.13b-1.93+1.93=10.05+1.93$
$9.13b=11.98$

Step 2: Divide both sides by 9.13.

$(9.13b)/9.13 = 11.98/9.13$
$b = 1.31215..$

Step 3: Round to the nearest hundredth.

1.31215.. ≈ 1.31

Therefore, b = 1.31.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Anvisha [2.4K]

Answer:

They will not have the same weight during the program

Step-by-step explanation:

Let x be the number of weeks.

<u>Sandra:</u>

Sandra is starting at 150 pounds and plans to lose 1 pound a week.

Weight after x weeks:

$150-x$

<u>Bernice:</u>

Bernice is starting at 135 pounds and plans to lose 1/2 a pound a week.

Weight after x weeks:

$135-\dfrac{1}{2}x$

Weights must be the same, so

$150-x=135-\dfrac{1}{2}x\\ \\\dfrac{1}{2}x-x=135-150\\ \\-\dfrac{1}{2}x=-15\\ \\x=30$

Since 30 weeks is more that 12 weeks (the duration of the program), they will not have the same weight during this program.
