1.)
6% of 38
1% of 38 = 3.8 ( you just move the decimal placement over by one.
1% * 6 = 6%
3.8 * 6 = 6%
3.8 * 6 = 22.8
6% =22.8
2.)
5% of 90
90/5 = 5%
90/5 = 18
18 = 5%
3.)
15/5 = 9/x
15/5 = 3
3 = 9/x
(nine divided by ? is three?....3!)
3 = 9/x(3)
3 = 9/3
3 = 3
x = 3
4.)
1/12 = .8/x
Multiply each side by ten.
1/12 * 10 = 5/6
.8/x * 10 = 8/x
5/6 = 8/x
Cross Multiply (switch the second numbers around)
5x = 6*8
Simplify
5x = 48
Divide both sides by 5 to get x by itself
5x/5 = x
48/5 = 9.6
*Whoo last problem lol*
5.)
A three liter bottle costs $2.97 what is the unit rate.
Well the unit is the object we're talking about, in this case a liter bottle.
The unit rate is how much it costs or is per unit.
Now that that's out of the way...
3L = 2.97
Like the other problems we want to get x by itself, so we'll divide by three)
3L/3 = L
2.97/3 = .99
L = .99
The Unit Rate is $0.99 per liter bottle.
Hope this helped :)
2(444x+3a+44c) I think so
Answer:
5
Step-by-step explanation:
1) so lets substitute -2 as x:
y=(-2)^2+1
(-2)^2=-2*-2=4
hence
y=4+1
y=5

kilograms of yellow potatoes bought is 8330 kg
<em><u>Solution:</u></em>
Given that James buys 245 kilograms of red potatoes
He buys yellow potatoes that weigh 34 as much as the red potatoes
To find: kilograms of yellow potatoes bought by James
Let "y" be the kilograms of yellow potatoes bought
Let "r" be the kilograms of red potatoes bought
kilograms of red potatoes bought = 245 kilograms
r = 245 kilograms
From given information,
Yellow potatoes weigh 34 as much as the red potatoes
here "as much as" means product or multiplication
Kilograms of yellow potatoes bought = 34 x kilograms of red potatoes bought
Thus kilograms of yellow potatoes bought is 8330 kg
The answer cannot be expressed in mixed number since whole numbers has no fractional part
