Answer:
27y - 6
Step-by-step explanation:
3(9y - 2) Multiply 3 times each term in the parentheses
3 * 9y = 27y
3 * -2 = -6
here's the way that i learned it:
convert them to mixed fractions and then go from there.
3.6 = 36/10 0.5 = 1/2
right now our problem looks like this: 36/10 ÷ 1/2 =
okay, so i learned the method keep it, switch it, flip it.
keep the first fraction in the equation, 36/10
switch the division sign to multiplication ÷ ⇒ ×
switch the numbers on the second fraction 1/2 ⇒ 2/1
okay, so our equation looks like this now:
36/10 x 2/1
okay, so now multiply across. (multiply the top numbers together and the bottom numbers together)
72/10
latly, we need to convert back to a decimal. divide the top number by the bottom one.
to do this, divide the top number by the bottom number
72/10
7.2
<em>i hope this was helpful. this is how i learned dividing with decimals, so it might be kinda complicated. if you still need help, let me know :)</em>

Answer:
<em>The area of the actual building lot is</em> 
Step-by-step explanation:
<u>Scaling</u>
The scaled rectangular building measures 7 feet by 5 feet. We know both magnitudes were scaled by a factor of 12, thus the real dimensions of the house to be built are 7*12=84 feet, and 5*12=60 feet.
The area of the actual building lot is calculated by:

Answer:
Step-by-step explanation:
1.
Find value of P that makes this true
4p-5=`9
Solve for P by isolating it on one side:
4p-5+5=9+5
4p/4=14/4
P=3.5
2.
Translate the Algebraic Expression:
A waiter earns $128 for 6 hours of work including $86 of tips.
Subtract tips from total:
128-86=42
Divide Value between hours.
42/6=7
$7 per hour
3.
Find the Value of X that makes this true
-4x+26=-2
Solve for X by isolating it on one side:
-4x+26-26=-2-26
-4x/-4=-28/-4
X=7
4.
What is the first correct step in solving the equation:
33-2x=31
Subtract 33 from both sides
