Answer:
13.30
Step-by-step explanation:
$79.80 / 6 hours = $13.30
Answer:
4 times 1 plus 3 equals 7
Step-by-step explanation:
In order to solve this problem, the approach should be formulating equations such that they form a system of linear equations. Let's start by assigning variables. Let x be the number of homeruns made by Peter, and y be the number of homeruns made by Alice. Therefore,
x = 2(y - 6)
This is the equation for the relationship between Peter's and Alice's hits. The second equation would be the sum of their hits:
x + y = 18
These are the two independent equations in order to solve the two unknowns, x and y. Substituting the first equation into the second equation,
2(y - 6) + y = 18
2y - 12 + y = 18
3y = 18 + 12
3y = 30
y = 10
Using y=10 to the first equation:
x = 2(10 - 6)
x = 8
Therefore, Peter made 8 homeruns, while Alice made 10 homeruns for a total of 18.
Answer:
34cm
Step-by-step explanation:
To find the missing sides you have to see how much the bottom is, then the other sides so in the case the bottom is 10cm and top is 3cm on each side. and you want to find the middle. so you would do 10 - 3 - 3 = 4
