What percent of 950 is 2​
Dima020 [189]

Answer: 0.21%

Step-by-step explanation: Please mark me brainlist

Step 1: We make the assumption that 950 is 100% since it is our output value.

Step 2: We next represent the value we seek with x

Step 3: From step 1, it follows that 100% = 950

Step 4: In the same vein x% = 2

Step 5: This gives us a pair of simple equations: 100% = 950(1)

x% = 2(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have
100%/x% = 950/2

Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%/ 2/950
---> 0.21%

I need help i dont understand this​

140 tickets sold at the door

Step by Step Explanation:

x = tickets sold in advance
y = tickets sold at the door

We use the formula ax+by=c and a+b=c

x + y = 514
17x + 20y = 9158

y = 514 - x
17x + 20(514 - x)
17x + 10,280 - 20x = 9,158
-3x + 10,280 = 9,158
-3x = -11222
x = 374

This is for tickets sold in advance so we need to find y

374 + y = 514
y = 140

140 tickets were sold at the door
