1. 1/3 - 7/8
rewrite the complex fraction as a division expression
show the complex fraction in simplest form.
step 1
we have
Multiply the first term by 8/8
so
(1/3)*(8/8)=8/24
Multiply the second term by 3/3
(7/8)*(3/3)=21/24
step 2
substitute in the original expression
8/24 -21/24
the fractions have the same denominator
so
(8-21)/24
-13/24
therefore
the answer is
-13/24
Answer: Let x = number of pounds of jelly beans
y = number of pounds of almonds.
Then, 4x + 8y = 33
2x + 3y = 13
Multiply the second equation by -2 to get the system:
4x + 8y = 33
-4x - 6y = -26
Adding the equations, we get 2y = 7. So, y = 3.5
Substitute for y in either of the given equations: 2x + 3(3.5) = 13
2x + 10.5 = 13
2x = 2.5
x = 1.25
ANSWER: a pound of jelly beans costs $1.25 and a pound of almonds costs $3.50.

Answer: "A"
Step-by-step explanation: To determine which relation is a function, we use the vertical line test. In other words, if we can draw a line that passes through only one point, then the relation is a function.
Image provided.
In the picture, you can see vertical lines and notice that the lines have only one point on them. On the other graphs, there is more than one point on the same line which makes it not a function.
Answer:
912
