7x + 9y = - 27_________eq1
3x - y = 3__________eq2
Multiply eq 2 by 9 and then add the resulting eq with eq1.
eq2 x 9 gives us 27x - 9y = 27___________eq3
add eq3 with eq1 we get.
34x = 0.
where x=0/34
x=0.
substitute x into any of the above equations to get y.
substitute x into eq1. we get:
7(0) + 9y =-27
9y = -27
y= -27/9
y = -3.
Answer:
3 boxes of small porridge
Step-by-step explanation:
625g x 5 = 3125
4125-3125=1000
1000 divided by 350 = 2.8
so there will be 2 full boxes of small porridge and 1 not full box of porridge.

Let x be the width
2x-3= length
(2x-3)(x)=14
2x^2-3x=14
2x^2-3x-14=0
(2x- 7)(x+2)=0
x=7/2 or x=-2
Since we know that negative values cannot exist in distance, we have to take 7/2 to as the correct answer.
The width would be 3.5 yards
Length= 2(3.5)-3
=4 yards
3.5 x 4 yards is the dimension of the rectangle

23.8÷28=0.85
0.85 Liters
every liter is 1000 mililiters.
0.85 Liters is 850 mililiters.
