7.7 divided by 1.4 = 5.5. So the flagpole is 5.5 times taller than meter stick
Thus flagpole is 5.5 m tall.
Answer:
Answer: It's relatively easy to find x in this problem. 4x+3y=12 means that the expression 3y needs to be 12 too, which gives us 12-6 or 6. That number divided by 4 is 2, so x=2! Congrats, you've found x!
Step-by-step explanation:
One way of solving this problem is to remove the parentheses all together and write the equation as 8x+6y = 54. Subtracting 54 from both sides would give us -8x + 6y = 18. The key point here is that when subtracting a negative number, we have to borrow one from our variable so instead our answer becomes (-8)x-6(y)=-54.
Answer: x2 + 4x + 11
Step-by-step explanation:
(x + 2)2 + 7
(x+2)(x+2) + 7
X2 + 2x + 2x + 4 + 7
x2 + 4x + 11
Answer:
x = 4
Step-by-step explanation:
Given
- 8 - x = x - 4x, that is
- 8 - x = - 3x ( add 3x to both sides )
- 8 + 2x = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
11.00*9.5=104.5
104.5*0.07=7.315
7.315+104.5=111.815
