The greatest common factor is the biggest number taken from the values.
Q1. The answer is <span>A. 5y^6
</span>
Since
, then
Back to our expression:
The greatest common factor is thus
Q2. The answer is <span>D. 12xy^2
</span>
We will use the rule
to factorise the exponents:
The greatest common factor is thus
Jonah recorded the points his team scored during its last nine basketball
games. The mean number of points scored was 42 and the MAD Was 4.4.
The MAD shows that the scores generally varied greatly from the mean.
The scores were mostly less than
38 (42 -4.4 = 37.6)
greater than
46 (42 + 4.4 = 46.4).

Answer: Equations (b) and (e) do not have solutions
Step-by-step explanation: b) The x cancels out (-10x + 35) = -10x + 318; 35 = 318???? NO. e) 3(x + 2) + 1 = x + 2(4 + x); 3x + 7 = 3x + 8. The x cancels out again.
The other s can be solved for x.
Answer:70;20
Step-by-step explanation:
Elimination:
3x - 9y = 3
6x - 3y = -24
3x - 9y = 3
18x - 9y = -72
(subtract)
-15x = 75
÷ -15
x = -5
(3 × -5) - 9y = 3
-15 - 9y = 3
+ 15
-9y = 18
÷ -9
y = -2
Substitution:
6x - 3y = -24
+ 3y
6x = -24 + 3y
÷ 6
x = 4 + 0.5y
3(4 + 0.5y) - 9y = 3
12 + 1.5y - 9y = 3
12 - 7.5y = 3
- 12
-7.5y = -9
÷ -7.5
y = 1.2
x = 4 + (0.5 × 1.2)
x = 4 + 0.6
x = 4.6
So this one didn't fail as much, but I got different numbers. If you have to give in values, I'd give in the values from the elimination because I don't trust myself when it comes to the substitution
