<u><em>Each answer is under each Part</em></u>
1. What is the price of you pizza with all the toppings?
<em><u>$16</u></em>
The pizza costs 12 dollars, and each topping costs 1.75 dollars, there are 4 toppings, so it's 12 + 1.75*4 = 12 + 4 = 16 dollars.
2. How much will you pay in tax?
<em><u>$0.80</u></em>
It costs 16 dollars and tax is 5%, so 5% of 16. 16*5% = 16*0.05 = 0.8, so 0.8 dollars, or $0.80
3. What is the total cost including tax?
<u><em>$16.80</em></u>
Add the cost of the pizza with the tax, 16 + 0.8 = 16.8, $16.80
4. How much will each of you need to pay to cover the total price?
<u><em>$4.20</em></u>
There are 4 people total, You and 3 friends, so divide the total cost by 4, 16.80/4 = 4.2, so $4.20
Solve for x
3x=4y-10
x=(4y-10)/3
solver for y
3x=4y-10
rewrite as 4y-10=3x
4y-10+10=3x+10
4y=3x+10
y=(3x+10)/4
Let's solve your equation step-by-step.
4(2x+8)=10x+2−2x+30
Step 1: Simplify both sides of the equation.
4(2x+8)=10x+2−2x+30
(4)(2x)+(4)(8)=10x+2+−2x+30(Distribute)
8x+32=10x+2+−2x+30
8x+32=(10x+−2x)+(2+30)(Combine Like Terms)
8x+32=8x+32
8x+32=8x+32
Step 2: Subtract 8x from both sides.
8x+32−8x=8x+32−8x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32
0=0
