Idk how to solve 0=4+n over 5

miv72 [106K]

0=4+n over 5
In number form the equation is
 $0= \frac{4+n}5}$

We want to isolate n, so to undue division we multiply, we'll multiply each side by 5 Leaving the equation as
 $0=20+n$

Next we'll subtract 20 from each side to isolate n
The equation would now be
 $-20=n$

So the answer is N=-20

The Venn diagram above represents the students who were sick one day in January at a Chicago high school. 80 students had only a

mrs_skeptik [129]

Answer:

370

Step-by-step explanation:

The venn diagram corresponds to students who were sick in January at a Chicago high school.

Students who had only fever= n(A) = 80

Students who had only headache= n(B) = 90

Students who had only cough = n(C) =60

Students who had both cough and fever = n(AC) = 10

n(AB) = 40:n(BC) = 30 n(ABC) = 20

Hence total students = 800

no of students who were absent due to other reasons = 100

REmaining students = 700

Students who were sick = sum of all =330

So no of students who were at school = 700-330 = 370

. What is the negative solution to this equation? 8x2 – 4x = 363

stiv31 [10]

Answer:

- x = 81 and 3/4

Step-by-step explanation:

8 × 2 – 4x = 363

16 - 4x = 363

Subtract 16 from each side:

16 - 16 - 4x = 363 - 16

- 4x = 327

Divide each side by 4:

- 4x ÷ 4 = 327 ÷ 4

- x = 81 and 3/4
