Answer:
The answer is 7000
Step-by-step explanation:
trapezoid area is 9600 - 2600 (square area) = 7000
If we round 6.254 to 6, then 2 * 6 = 12
If we round 54 to 50, then 9 * 50 = 450
Let's check with the appropriate calculations to find out how close we are:
2* 6,254 = 12,508
9 * 54 = 486
So it's close enough :)
Answer:
x= 8/5 - 4/5y
Step-by-step explanation:
To get x independent we need to get everything else on the side x is on to the other side. We can start by adding 4y to the other side. We add because its negative and negative and positive cancel each other out.
-5x-4y=-8
add 4y
-5x= - 8 + 4y
Then to get the negative 5 to the other side we divide it to cancel it because it is multiplying right now.
-5x= - 8 + 4y
divide -5
x= - 8/-5 +4/-5y
in the fraction -8/-5 the negatives cancel out to get 8/5 and for 4/-5y we can more the negative to get us our final answer which is x=8/5-4/5y
Answer:
50 gram
Step-by-step explanation:
The actual percentage recipe = 100%
Percentage Increase in recipe = 60%
Recipe used as a result of increment = 80 gram
Hence,
100% + 60% = 80
160% = 80g
If :
160% = 80
100% = x
Cross multiply
1.6x = 80 * 1
1.6x = 80
x = 80 / 1.6
x = 50
Recipe required 50 gram
