Thankfully, there is no real GCSE in algebra. But if there was, would you pass?
a – 67a – 67a + 10
Starting with 4a – (3a + 6) you first simplify by removing the brackets, to get 4a – 3a – 6. Subtracting 3a from 4a gives the final answer: a – 6.
b/a is equal to two thirds, a – b is 1 and ab is 6.
Yes, that person must be very good at maths.No, they're lying.
w = 1 works, but if you set w as -1 the above expression works out as -2. The two correct values are 1 and -2.
x > 5x < 5x > 3x < 3
The expression simplifies to 3x > 15, so x > 5.
y = 6y = 7y = 8
8y = 64, so y = 8.
x² + y²2x + y²2x + 2y²
x + x = 2x and y * y = y² so the full expression is 2x + y².
1, 2, 3, 41, 2, 3, 51, 2, 3, 61, 2, 4, 8
In a geometric progression each number is multiplied by the same common factor to get the next term. In the sequence 1, 2, 4, 8 the common factor is 2.
y = x + 10y = 2x – 5y = 10x + 2
The number before the x is the gradient of the line, so y = 2x – 5 is parallel to y = 2x + 10.
For the equation to be true, either x – 4 = 0 or x + 8 = 0.
x could also be -4.
The 2nd term in both sequences is 5.
x=1, y=2x=2, y=2x=2, y=4
If you substitue y=2x into the first equation you get 5x=10, so you know x=2. Then just put that into y=2x to get y=4.
Only An A* Student Can Get Full Marks On This GCSE Algebra Test
At least there is no such thing as GCSE Algebra irl.
Well done, you scraped a pass on this made-up GCSE. Not bad work at all.
Congrats, you passed!
Not bad at all! Either you're still in school, or you've somehow kept up your algebra skills.
Congratulations! You're really good at algebra.
Top marks! Congrats.
