Answer: (i) 4x - 40 = 76

(ii) 29 questions

Step-by-step explanation:

Let the total number of questions be x.

Since he received 4 points for every correct answer and he got 10 answers wrong , this means he lost 40 points , the equation thus become

4x - 40 = 76

To find the value of x , add 40 to both sides

4x = 116

divide through by 4

x = 29

Therefore , there are 29 questions on his math test

Answer:

correct choice is B

Step-by-step explanation:

If d represents the number of desks in each row and the administrators want there to be 13 less rows than the number d of desks in each row, then the number of rows is d-13.

The total number of desks in all rows is

$d\cdot (d-13)=d^2-13d.$

Due to space limitations, there should be fewer than 264 students in the cafeteria. Therefore,

$d^2-13d$

– 3х – бу = 17; (6, 3)

I'm going to assume that you want to know whether the coordinate satisfies the equation. Let's find out;

-3х - 6у = 17

-3(6) - 6(3) = 17

-18 - 18 = 17

-36 ≠ 17

The point (6, 3) does NOT satisfy the equation.

Best of Luck!
