To answer this, set up a system of equations. What we know is that
5x + 2y = 100
And...
x+y=38
x represents the unknown number of 5 points questions
y represents the unknown number of 2 point questions
In my opinion the easiest way to solve this is to use substitution (that is when you find out the value of one variable, either x or y, and substitute that value as the variable).
So,
x+y=38
Subtract x from both sides
y=38-x
Now, plug (38-x) in as y in the other equation.
5x + 2(38-x) = 100
5x + 76-2x= 100
3x+76=100
3x=24
x=8
Now that you know that x=8, you can solve for y.
5x+2y=100
5(8)+2y=100
40+2y=100
2y=60
---- ------
2 2
y=30
X=8
Y=30
There are 8 five point questions on the test and 30 two point questions on the test
A puddle
Explanation:
Let's think of it this way. You should drink 2 - 3 liters of water everyday, and you obviously aren't suppose to drink a lake amount of water everyday, so a puddle makes more sense.
Answer:
55 special dinners
Step-by-step explanation:
From the question,
Last month rudys tacos sold 22 dinner specials.
The next month they sold 250% of last months dinners.
Hence:
250% × 22 special dinners
= 55 special dinners
The number of dinner specials they sold this month is 55 special dinners
Answer:
4/6
Step-by-step explanation:
3 x 2 = 6
2 x 2 = 4
2/3 = 4/6
