You have to make an inequality:
1.2x + 6 ≤ 20
- 6 - 6 isolate x
1.2x ≤ 14
÷1.2 ÷1.2 isolate x
x ≤ 11.666
Since you can't buy 2/3 of a pack, she can only buy 11 pieces of gum.
Hope this helps!
If you would like to complete the factorization, you can do this using the following steps:
<span>4p^2 + 36p + 81 = (2p + 9) * (2p + 9) = (2p + 9)^2
</span>
The correct result would be 9.
Answer:
0,4,8,12,16
Step-by-step explanation:
so for the value of x- just substitute it into the equation
so -2
8+4(-2)
8-8=0

first I made the fraction have equal denominators which was 6 by doing that I multiplyed the numerator and the denominator
1/2
1×3=3
2×3=6
therefore 1/2 being equivalent to 3/6
1/3
1×2=2
3×2=6
therefore 1/3 being equivalent to 2/6
now you would be able to add the numerators, so 2+3=5
therefore being 5/6 of the paper is devoted to news and pictures
