Answer:
<em>To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.</em>
Step-by-step explanation:
<u>Proportions</u>
The hybrid car can travel 40 miles per gallon.
Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.
Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.
To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.
Answer: x=64.
Step-by-step explanation:
48=3x/4
Multiply both sides by 4 : 192=3x
Divide both sides by 3. : x=64
Check: 64*3=192; 192/4=48 J=48 So x is 192.
Hope this helps! :p
Answer:
The answer is 17
Step-by-step explanation:
First step is dividing 45÷9 = 5
Then, 2² = 4
Now you have: 4 × 5 - 3 => 20 - 3 => 17
Answer:
11
Step-by-step explanation:
- 9+3(8-3(7-5))-4
- 9+3(8-3(2))-4
- 9+3(8-6)-4
- 9+3(2)-4
- 9+6-4
- 15-4
- 11
I first delt with simplifying the parentheses till step five. Then in five I just added 9+6 because it came before the -4. But PEMDAS is very important when doing these problems because it tell you the order
- P (parentheses)
- E (exponents)
- M (multiply)
- D (divide)
- A (add)
- S (subtract)
- **the biggest thing is that with multipe and divide it depends what comes first. If you see divide before multipe in the problem just do it that way. It is the same way with add and subtract but The multiple/divide group ALWAYS comes BEFORE add/subtract
