5*36.95= $<span>184.75
2*42.99= $</span><span>85.98
3*38.95= $</span>116.85
1*52*0.6=$<span>31.20 (40% off) multiply by 0.6)
Add 184.75+85.98+116.85+31.20=$</span>418.78 - 20% thus: 418.78*.8= $ <span>335.024</span>
168 divided by 2 equals 84
Answer:
5x-2x-x = 10 9z • 7p = 378
Step-by-step explanation:
With equations like these you're basically just plugging numbers in where there are variables. so if you have 5x-2x-x when x=5, you just plug in 5 wherever x is. 5x-2x-x turns into (5•5)-(2•5)-(1•5). you multiply the expressions in the parentheses to get 25-10-5 and then you simply subtract.
1. 5x-2x-x
2. (5•5)-(2•5)-(1•5)
3. 25-10-5
4. 10
We can do the same thing with your second example. 9z•7p when z=2 and p=3. When there is a z, you plug in a 2. When there is a p, you plug in a 3.
1. 9z•7p
2. (9•2) • (7•3)
3. 18 • 21
4. 378
