Step-by-step explanation:
B) 64 cm because 8+8+8+8+8+8+8+8, also known as 8x8=64
Answer:
3. B.
1. 3551.
Step-by-step explanation:
3. For two equations to have infinite solutions, the equations must be the same.
y = -5x + 6
5x + y - 6 = 0
Multiply the whole thing by 2.
10x + 2y - 12 = 0
B.
1. Michelle rides roller coasters 3 times and plays the super swing 5 times, which means that A = 3 and B = 5.
Marty rides the roller coasters 5 times and plays the super swing 1 time. That means C = 5 and D = 1.
So, your answer will be 3551.
Hope this helps!
Answer:
Step-by-step explanation:
x + 2y = 14 ...............(1)
6x + 3y = 21 ..............(2)
Solve for x in equation 1
When x + 2y = 14
Therefore x = 14 - 2y ...................(3)
Now put equation 3 in equation 2 and solve
6x + 3y = 21 .............(2)
6(14 - 2y) + 3y = 21
Open the bracket and resolve
84 - 12y + 3y = 21
-9y + 84 =21
Now collect the like terms
-9y + 84 = 21
-9y = 21 - 84
-9y = -63
Divide through by -9 to get y
y = -63/-9
y = 7
Substitute for y in equation( 3 )to x
x= 14 - 2y............(3)
So, x = 14 - 2(7)
x = 14 - 14
x = 0.
Therefore x = 0 and y = 7
Check: From equation (1)
x + 2y = 14
Now, put x = 0 and y = -2
Therefore, 0 +2(7) =14
0 +14 = 14
Well first you multiply 66 by 3 that gives you 198+2=200 so divide 200 divide by 48
