Answer:

17 number of 3 marks problems

Step-by-step explanation:

Given that in a Math test total number of points is 111.

Out of these questions there would be a mixture of 4 marks and 3 marks questions.

Let x have 3 marks and y 4 marks problems

Since total number of questions =32

we have x+y =32 ...i

Since total points = 111, we have

3x+4y =111 ...ii

Multiply i by -3 and add with ii

y = -96+111=15

x=17

VErify:

There 17, 3 marks questions and 15, 4 marks questions

Total question = 32

Total points = 17(3)+15(4)=111

PLS HELP! 7x +10y= -23<br><br> 7x + 6y = - 39
mote1985 [20]
4y = -23 + 39
4y = 16
y = 4

Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9

x = -9
y = 4
