I think is
4 x + 2y
256x + 16y
Hello! I can help you!
4. So we are talking about 15 miles a day for 5 days each week. 15 * 5 is 75. That's 75 miles in one week. He continues doing this for 8 weeks. Now, all we have to do is multiply 75 by 8 to get the total amount of miles. 75 * 8 is 600. There. Noah bikes 600 miles in 8 weeks.
6. We are rounded to the nearest hundred. If the number behind the digit we are rounding is 5 or more, the number goes up. If it's 4 or less, the number goes down. 329,167 has 1 one in the hundreds place. 6 is in the tens place behind it. 6 is more than 5, so we round up. The number rounded to the nearest hundred is 329,200.
8. Okay. So 132 are sold in the summer and 5 times that amount is sold in the winter. The equation would be this: 132 * 5 = s. The variable s represents the snowboards. All you have to do is multiply the numbers. 132 * 5 is 660. There. The store sells 660 snowboards in the winter.
We know that
the rectangle with the largest area is the square
so
[perimeter of a square]=4*x
where
x is the length side of a square
4*x=175--------> x=43.75 cm
the answer is
the dimensions are 43.75 cm x 43.75 cm
Answer:
206 pounds
Step-by-step explanation:
<u>11 pound bags</u>
To find the total number of pounds, multiply the number of pounds by the number of pounds in one bag.
bags*pounds
Abi bought 10 bags that each weighed 11 pounds.
10 bags*11 pounds
10*11
110
110 pounds
<u>8 pounds bags</u>
To find the total number of pounds, multiply the number of pounds by the number of pounds in one bag.
bags*pounds
She bought 12 bags that weighed 8 pounds each.
12 bags*8 pounds
12*8
96
96 pounds
<u>Total</u>
To find the final total, add together how many pounds of 11 pound bags she bough and how many pounds of 8 pound bags she bought.
pounds from 11 pound bags+pounds from 8 pound bags
She bought 110 pounds from 11 pound bags and 96 pounds from 8 pound bags.
110 pounds+96 pounds
110+98
206
<u>She bought a total of 206 pounds</u>
Answer: 
Step-by-step explanation:
We must remember that, by definition, Scientific notation has the following form:
Where 
and "b" is an integer.
Let be "x" the distance light will travel in 1 minute.
According to the information provided in the exercise, the light travels 
per second.
We know that:
To write this in Scientific notation, move the decimal point three places to the left:
Then, we can set up the following proportion:
Solve for "x" (We must remember the Product of powers property: 
):
