Answer:
Step-by-step explanation:
Given:
(y/y - 4) - (4/y + 4) = 32/y^2 - 16
Note y^2 - 16 = (y - 4 ) × (y + 4)
Multiplying the equation; both sides by y^2 - 16,
y (y + 4) - (4(y - 4)) = 32
y^2 + 4y - 4y + 16 = 32
y^2 = 32 - 16
Squaring both sides,
y = sqrt(16)
= 4
So you are multiplying the fractions together. You do not need a common denominator. You multiply the numerators together and the denominators to get your new fraction.
1x4=4
4x7=28
4/28
This fraction can now be simplified by dividing the numerator and denominator by 4
4/28x4/4
1/7
Answer:
22.39 should be the last side on the triangle
Answer:
300
Step-by-step explanation:
12% of x = 36
12/100 x = 36
12x/100 = 36
12x=36x100
12x=3600
x=3600/12
x=300
Answer:
each taco costs $8 and each soda $4
Step-by-step explanation:
the difference between the two is $16 and half of $16 is $8 so you can tell each taco is $8. That automatically shows that the rest of the cost is $8 which half of is $4
