X+3x-11=4
4x=4+11
x=15/4
x=3.75
Answer:
see explanation
Step-by-step explanation:
Using the rules of exponents
⇔
and
= 1
Substitute the values of x into 
x = 0 →
= 1 ⇒ a = 1
x = 2 →
=
=
, hence
b = 
x = 4 →
=
=
, hence
c = 
Basically we want to know how many times 5/8 goes into 5 1/4.
5 1/4 ÷ 5/8 = 21/4 ÷ 5/8 = 21/4 × 8/5 = 42/5 = 8.4 bags
Since we cannot have a fraction of a bag, he can fill 8 bags completely.
answer: 8 bags
Answer:
y = 12
Step-by-step explanation:
Complementary angles sum to 90 , so
3y - 1 + 4y + 7 = 90
7y + 6 = 90 ( subtract 6 from both sides )
7y = 84 ( divide both sides by 7 )
y = 12
