Number of questions worth 5 points = 10

Number of questions worth 2 points = 25

Further explanation:

The given system is a system of linear equations in two variables.

We will use the subsitution method to solve the system

Given equations are:

x+y=35\\5x+2y=100

From equation no 1:

x+y=35\\x=35-y

Putting x=35-y in second equation

5x+2y=100\\5(35-y)+2y=100\\175-5y+2y=100\\-3y=100-175\\-3y=-75\\\frac{-3y}{-3}=\frac{-75}{-3}\\y=25\\Putting y=25 in first equation\\x+25=35\\x= 35-25\\x=10

Hence,

Number of questions worth 5 points = 10

Number of questions worth 2 points = 25

vladimir2022 [97]

Answer:

The value of s is "90". A further explanation is given below.

Step-by-step explanation:

The given expression is:

⇒ 10=s÷2+7

i.e,

⇒ 10=\frac{s}{2+7}

On solving the above expression, we get

⇒ 10=\frac{s}{9}

On applying cross-multiplication, we get

⇒ 10\times 9=s

⇒ 90 = s

What’s the answer to the word problem the difference of three times a number and 1
harina [27]

Answer:

There is no answer. I'm sorry but more information is needed in order to find the answer.

Step-by-step explanation:

However, the problem can be written.

It will look like:

3n - 1.

Since the number can be anything, this is not an answerable question because it must equal a number on the right side of the equation.
