Answer:12
Step-by-step explanation:
there is 4 pounds total, and each package is 1/3 a pound, so 3 packages, (1/3x3)=3 so 3 x 4 for all packges= 12. Hope this helps!
'Complement' = difference between an angle an 90 degrees.
'Supplement' = difference between an angle and 180 degrees.
Complement of A = 90 - A
Supplement of A = 180 - A
The problem says that the complement is 1/6 of the supplement, right ?
So <u> 90 - A = (1/6) x (180 - A)</u>
Multiply each side of this equation by 6 :
540 - 6 A = 180 - A
Subtract 180 from each side:
360 - 6 A = - A
Add 6A to each side :
360 = 5 A
Divide each side by 5 :
<u>A = 72°</u>
Answer:
Earned = 160 + 20d
Step-by-step explanation:
Seeing as Elmo works 20 hours per week at each job, that means he worked 20 hours at the $8 job and 20 hours at the $d job.
First find how much he earned from his $8/hr job.
(20)8 = 160
Elmo earned $160 at this $8/hr job.
Next, we know he earns $d/hr at his other job, and he works 20 hours at that job as well.
(20)d = 20d
Add the earnings from both jobs together.
160 + 20d = total earnings
Answer:
Step-by-step explanation:
Before subtracting we require the fractions to have a common denominator.
The lowest common multiple of x + 4 and x + 6 is (x + 4)(x + 6)
Multiply the numerator/denominator of the first fraction by x + 6 and
multiply the numerator/denominator of the second fraction by x + 4
= 
- 
Expand the numerators and simplify leaving the denominator

Answer: x=14
Step-by-step explanation:
Subtract 2
from both sides of the equation.
X=16−2
Subtract 2
from 16
.
X=14
