Answer:
The answer to your question is (2,12). Hope you have a nice day.
Step-by-step explanation:
So, first you put in the x value. 8(2)-y=4, 16-y=4. Then you subtracted 4 from each side. 4-4=0 and 16-4=12. 16-12=4.
Answer:
32 lb
Step-by-step explanation:
Let a = number of pounds of type A coffee used.
Let b = number of pounds of type B coffee used.
From the statement:
"This month's blend used three times as many pounds of type B coffee as type A"
we get this equation:
b = 3a
"Type A coffee costs Karen $5.50 per pound, and type B coffee costs $4.25 per pound."
She spend (in dollars) 5.50a + 4.25b, but since b = 3a, we get
5.5a + 4.25(3a) = 5.5a + 12.75a.
She spent $584, so
5.5a + 12.75a = 584
18.25a = 584
a = 32
She used 32 lb of type A coffee.
Going from left to right:
the first one is neither, they would be adjacent technically
the second one is complementary because both angles equal 90 degrees.
the third one is complementary because both angles added equal 90 degrees. the last one is supplementary because both angles added equal 180 degrees.
hope this helps you!!
Answer:
15cm
Step-by-step explanation:
The formula to calculate the area of a parallelogram is base x height.
Since we know the height and area, we can write the equation:
135 = base x 9
Now we can just divide 9 from both sides to solve for base:
135/9=basex9/9
So we get:
Base = 135/9=15
The length of the base is 15cm.
Hope this helped!
