-21x+28 is factored into:
-7(3x-4)
Answer:
8x = 75 + 5x
where x = length of one brick
25cm
Step-by-step explanation:
50,000
Since 736 is
500, we round it off to 50 000 instead of 49000.
The given equations are:
5x - 2y = 88
3x + 4y = 58
Multiplying the 1st equation by 2, we get the new set of equations as:
10x - 4y = 176
3x + 4y = 58
Adding the two equations, we get:
10x - 4y + 3x + 4y = 176 + 58
13x =234
x = 18
Using the value of x in 1st equation, we get:
5(18) - 2y = 88
- 2y = 88 -5(18)
-2y = -2
y = 1
So, the solution of the equation is (18, 1)
