5x-2+3x-4 = 2x-8+x+2
First we have to put all X's on side and the remaining numbers on the other, changing their signal if they move across the equal sign. Therefore,
5x+3x-2x-x = -8+2+4+2
5x = 0
x= 0/5
x= 0
Answer: 3.5, 4.5, 9.5, 3.5
Step-by-step explanation:
Look at the image below to see where A, B, C, and D are.
A + B = 8
B + D = 8
A + C = 13
C - D = 6
we can see that A + B = 8 and D + B = 8, so A = D
substitute this into A + C = 13 to get D + C = 13
from D + C = 13 we can get D = 13 - C
plug this into C - D = 6 to get C - (13 - C) = 6
2C - 13 = 6
2C = 19
C = 9.5
Now we can find D = 13 - C = 13 - 9.5 = 3.5
D = 3.5
Now we can find A = D = 3.5
A = 3.5
Now we can find B from A + B = 8
B = 8 - A = 8 - 4.5 = 4.5
B = 4.5
Answer:
2
Step-by-step explanation:
you find the gradient by doing y-y`/x-x`
so 3-9/-2-1 which gives you -6/-3 which is 2
Answer:
B
Step-by-step explanation:
To find the distance we need to add the numbers:
2 - (-3/4) = 2 + 3/4
6750000 should be the answer :)
