I think there is only one 0. If x=2, then 3 does not equal 0.
The bets answer that could go into 81 and 16 would be 1
Y=x+5
Let's say we are given that x is equal to 5.
Thus, since x=5, we can <em>replace</em> x with the number 5.
So instead of y=x+5, we now have:
y=5+5=
Another example:
x=4+y
where y= 2
x=4+2
Answer:
MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8

Define x and y :
---------------------------------
Let x be the number of large boxes.
Let y be the number of smaller boxes.
---------------------------------
Construct equations :
---------------------------------
x + y = 125 -------------------------- (1)
50x + 30y = 4850 ---------------- (2)
---------------------------------
From equation (1) :
---------------------------------
x + y = 125
x = 125 - y
---------------------------------
Substitute x = 125 - y into (2) :
---------------------------------
50 (125 - y) + 30y = 4850
6250 - 50y + 30y = 4850
20y = 1400
y = 1400 ÷ 20
y = 70
---------------------------------
Sub y = 70 into equation 1
---------------------------------
x + y = 125
x + 70 = 125
x = 55
---------------------------------
Find the number of boxes :
---------------------------------
Large box = x = 55
Small box = y = 70
---------------------------------------------------------------------------------------------------
Answer: There are 55 large boxes and 70 small boxes.
