murzikaleks [220]

Let x be the total of students in their Junior Year.

So, 84% of x =378

84% = 0.84

0.84x=378 (divided by 0.84)

x= 450 students.

The ones that chose not to take spanish will be:

450-378=72

72 students chose not to take spanish in their junior year.

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.
