4(n−5)=6n+8Step 1: Simplify both sides of the equation.4(n−5)=6n+8Simplify: (Show steps)4n−20=6n+8Step 2: Subtract 6n from both sides.4n−20−6n=6n+8−6n−2n−20=8Step 3: Add 20 to both sides.−2n−20+20=8+20−2n=28Step 4: Divide both sides by -2.−2n−2=28−2n=−14

IF ONE THIRD OF THE SCHOOL STUDENTS LIKE MATHEMATICS AND 400 STUDENTS DO NOT LIKE MATHEMATICS , THEN HOW MANY STUDENTS DOES THE

boyakko [2]

Answer:

There are 600 students in this school.

Step-by-step explanation:

Let p represent the total population of the school.

Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:

p - (1/3)p = (2/3)p

400 students do not like math, so (2/3)p = 400.

Solve this for p by multiplying both sides by (3/2):

(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.

There are 600 students in this school.

Can someone help me find x

Viefleur [7K]

Answer:

Rounded to the nearest tenth: $x=5.7$ in

Rounded to the nearest hundredth: $x=5.74$ in

Step-by-step explanation:

We have a right triangle with a given angle of 35°. We also have the opposite side of that angle, $x$ , and its hypotenuse 10 in. To find $x$ , we are using the trig function that relates the opposite side with the hypotenuse; in other words, the sine trig function.
