Mathematics

Answer:

x = 7.

Step-by-step explanation:

The given equation is  

8x-2y=48

We need to find the value of x, when y=4.

Substitute y=4 in the given equation and then solve for x.

8x-2(4)=48

8x-8=48

Add 8 on both sides.

8x=48+8

8x=56

Divide both sides by 8.

x=\dfrac{56}{8}

x=7

Therefore, the value of x is 7, when y=4.

In a classroom of 33 students, the ratio of boys to girls is 3:8. How many boys are in the class?
Hunter-Best [27]
X=number of boys
y=number of girls.

We can suggest the following system of equations:
x+y=33
x/y=3/8

We solve this system of equations by substitution method.
x/y=3/8       ⇒x=3y/8

(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24

x+y=33
x+24=33
x=33-24
x=9

number of boys /total number of students=9/33=3/11

There are 9 boys and 24 girls in the class. 

Answer: C: 9. since 3/11 of the students are boys.

6x-2(-3x-5)=154 <br><br> What the answer
Fofino [41]

Answer:

x = 12

Step-by-step explanation:

Simplifying

6x + -2(-3x + -5) = 154

Reorder the terms:

6x + -2(-5 + -3x) = 154

6x + (-5 * -2 + -3x * -2) = 154

6x + (10 + 6x) = 154

Reorder the terms:

10 + 6x + 6x = 154

Combine like terms: 6x + 6x = 12x

10 + 12x = 154

Solving

10 + 12x = 154

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -10 + 12x = 154 + -10

Combine like terms: 10 + -10 = 0

0 + 12x = 154 + -10

12x = 154 + -10

Combine like terms: 154 + -10 = 144

12x = 144

Divide each side by '12'.

x = 12

Simplifying

x = 12
