There were 100 questions on a math test. If Jamal got 4 times as many right as he got wrong, what was Jamals score?

IgorLugansk [536]

Jamal's score is 80

<u>Explanation:</u>

Given:

Number of questions = 100

Let w be the number of wrong answers

Let r be the number of right answers

According to question,

r = 4w

r + w = 100

Solving both the equations we get:

4w + w = 100

5w = 100

w = 20

If w = 20 then r = 4 X 20 = 80

Therefore, Jamal's score is 80

Use substitution method <br>3x +4y+175x-2y=11

Viefleur [7K]

$3x +4y+175x-2y=11$

$4y-2y+175x+3x=11$

$2y+178x=11$

$2y=11-178x$

$y=\frac{11-178x}{2}$

$y=-89x+\frac{11}{2}$

$178x=-2y+11$

$x=\frac{-2y+11}{178}$

$x=\frac{-1}{89} y+\frac{11}{178}$

write the equation to solve for x 3x + 21 6x - 60 please help i was given 3x+21=6x-60 thats wrong can someone please help richar

Dmitry [639]

Answer:

<h2>3x + 21 = 6x - 60 </h2>

Step-by-step explanation:

parallel angles are equal

3x + 21 = 6x - 60

combine similar terms:

3x - 6x = -60 - 21

-3x = -81

x = 81/3

x = 27

now, plugin the value of x=27 back into the equation to get the angle:

= 3x + 21

= 3(27) + 21

= 102

= 6x - 60

= 6(27) - 60

= 102

as you noticed, both values are equal 102 = 102 because its a parallel angles

so the equation is 3x + 21 = 6x - 60

================================

i am pretty sure its correct.
