Answer:
x greater than or equal to 4
Answer:
(a) 4
(b) 4 * (7+3)
Step-by-step explanation:
(a) Let's first start by prime factorizing (finding the prime factors) 28 and 12:
12: 2*2*3
28: 2*2*7
We can see here they both share a common factor of 2*2, which is 4, therefore the GCF is 4.
(b) Factor a 4 out from the equation:
This gives us:
4 * (7+3)
Step-by-step explanation:
1/5x+60=2/3x-2
subtract 1/5x from 2/3x
when you do that you should get 0.46x repeating
then you add two to 60
you should get 62
62=0.46x
divide x
you get 134.7
Answer:
C. 14
Step-by-step explanation:
Add LM and MN
(3x + 5) + (4x + 7)
(4x + 3x) + (5 + 7)
7x + 12
As we know the total is 33
So,
7x + 12 = 33
Subtract 12 from 33, which gives me 21
Now,
7x = 21
To make x alone, divide both sides by 7, and then we will get x = 3
If x = 3
LM = 3x + 5
= (3*3) + 5
= 9 + 5
= 14
