Answer:
2(5)+5=15
Step-by-step explanation:
1. you have the equation 2b+c
2. then you add the numbers for c and b
3. so b=5 and c=5
4. once you add it into the problem then you get 2(5)+5 make sure you remember to times 2 x 5
5. then you do PEMDAS
6. you do multiply so 2x5 is 10
7. then do 10+5 and you get 15 as your answer.
It would help to first find the unit rate. We know that the plane flies 810 km per 1.5 hours. Divide by 1.5 on both sides:
810/1.5 = 540 km/hour
Then, multiply both the hour and the distance by 2:
540 * 2 = 1080 km/2 hours.
Answer:

Answer:
70.
Step-by-step explanation:
Let x be the required number.
We are asked to find the number whose 90% equals to 63.
We can represent our given information in an equation as:
Now, we need to solve for x.
Therefore, 90% of 70 is 63.
Answer:
Step-by-step explanation:
When finding the volume, we multiplied the 3 dimensions with degree of 1, 1 and 3 and got the binominal of degree 5. We summed up the degrees: 1 + 1 + 3 = 5.
- The <u>SUM</u> of the degrees of each factor is the degree of the product.
