Answer:
x=4
Step-by-step explanation:
1/2x -2= 8
add 2 to both sides
1/2x = 10
multiply 1/2 to both sizes
x= 8/2 o
multiply
x= 4
I'm assuming your teacher wants you to calculate the speed
1/2 = 0.5
3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5
If a plane flies 840 miles in 3.5 hours, then,
speed = distance/time
speed = (840 mi)/(3.5 hr)
speed = (840/3.5) mph
speed = 240 mph
<h3>Answer: 240 mph</h3>

Answer:
She made She made 100 grams of 45% sugar syrup.
Step-by-step explanation:
Genna added 45 grams of sugar into 55 grams of water.
Total amount she mixes = 45 + 55 = 100 grams.
Percentage of sugar in total mixture (sugar syrup) = 45 grams sugar in 55 grams syrup.

Here, Solute is sugar and Solvent is water.
mass of solute = 45
mass of solute + mass of solvent = 100
Putting values, we get,


Thus, She made She made 100 grams of 45% sugar syrup.
