Answer:
1.4
Step-by-step explanation:
12x+3x=15+6
15x=21
X=21/15
X=7/5 or 1.4
Answer:
up 1 over 7 (1,7) 1 = x and 7 = y
Step-by-step explanation:
0 plus 1 is 1. 1 plus 1 is 2. 2 plus 1 is 3. 3 plus 1 is 4
-6 plus 7 is 1. 1 plus 7 is 8. 8 plus 7 is 15. 15 plus 7 is 22
Answer:
1 = 137
2 = 43
3 = 43
4 = 137
Step-by-step explanation:
for the first line, do (180-137 = 43)
then, 43 would be corresponding angle to 2 - making them equal
2 would be vertically opposite to 3, making them equal
137 and 1 are corresponding- making them equal
4 is vertically opposite to 1 - making them equal
Answer:
y = 84
Step-by-step explanation:
1) add 3 to both sides of your equation to cancel out the -3
end up with: (1/3)y + 14 = (1/2)y
2) multiply both sides of your equation by 2 to cancel out the (1/2)
end up with: (2/3)y + 28 = y
3) subtract (2/3)y from both sides of the equation to cancel out the positive (2/3)y
end up with: 28 = (1/3)y
4) multiply both sides of the equation by 3 to cancel out the (1/3)
end up with: 84 = y
Answer:
x=3
Step-by-step explanation:
Step 1: Add two to 7 and inverse the minus 2
3x=7+2 3x=9
Step 2: Divide each number by 3.
3x/3=x and 9/3=3
so x=3
