Step-by-step explanation:
21/7=3 This means that 21 is 3 times more than 7.
Answer:
0.117
Step-by-step explanation:
(-0.3)(-0.39)=0.117
First, we take the squares in the right and left bottom. They're equal in the length of 5m so the region of each one of them is:
now we take the rectangular above, it has a length of 28m and a width of (9-5=4m) so its region is:
Now the region of the shaded area is region of both of the squares and the rectangular which is:
So the region of the shaded area is 162m^2
D.15 because 15 divided by 5 is 3 and 3+7 is equal to 10. Hope that helped
You don’t know how many adults were there and how many students were there.
But,
$8(adults) + $5(students) = $19060
And,
Adults + Students = 2570
Let A = adults and S = students
8A + 5S = 19060
A + S = 2570
This is called a system of equations. To solve, you need to rearrange both equations to solve for one of the variables, you can pick any. This makes them cancel out so you can focus on 1 variable. After solving, you can plug the solved variable back into any of the given equations and solve for the second one.
S = 19060/5 - 8A/5
S = 3812 - (8A/5)
This is the first equation rearranged to solve for S
Second:
A + S = 2570
S = 2570 - A
Now, equal each other
3812 - (8A/5) = 2570 - A
Solve for A
3812 + A = 2570 + 8A/5
19060 + 5A = 12850 + 8A
19060 - 12850 = 3A
6210 = 3A
2070 = A
There were 2070 adults
Now, plug A back into any of the 2 equations and solve for S
A + S = 2570
2070 + S = 2570
S = 2570 - 2070
S = 500
2070 adult tickets were sold
500 student tickets were sold
