Answer: 79 degrees
Step-by-step explanation:
4x+1 + 3x+4 = 180
7x + 5 = 180
7x = 175
x = 175:7 = 25
m8 = 3x + 4 = 3*25 + 4 = 79
Answer:
B.)536 
Step-by-step explanation:
Find the volume of all the fish tanks.
Green fish tank...
4 x 9 x 6 = 216
Brownish fish tank...
4 x 4 x 8 = 128
Orange Fish tank...
6 x 4 x 8 = 192
Since we are COMBINING the fish tanks, we add the volumes.
216 + 128 + 192 = 536
536

The length of the yard is 25ft.
In order to find this we first need to set up variables for the length and the width. Since we don't know anything about the width, we'll set it as x. Then, we know the length is equal to ten more than three times the width. Since the width is x, we can write the length as 3x + 10. Now we can use the formula for the perimeter of a rectangle to solve for x.
2l + 2w = P
2(3x + 10) + 2(x) = 60
6x + 20 + 2x = 60
8x + 20 = 60
8x = 40
x = 5
Now that we have a value for x, we can plug into the length equation and find the length.
3x + 10
3(5) + 10
15 + 10
25
1, 4, and 5:) hope this helps.
