Answer:
3/16
Step-by-step explanation:
32(4x−1)−3x=54−(x+2)
32(4x−1)−3x=54+−1(x+2)(Distribute the Negative Sign)
32(4x−1)−3x=54+−1x+(−1)(2)
32(4x−1)−3x=54+−x+−2
(32)(4x)+(32)(−1)+−3x=54+−x+−2(Distribute)
6x+−32+−3x=54+−x+−2
(6x+−3x)+(−32)=(−x)+(54+−2)(Combine Like Terms)
3x+−32=−x+−34
3x+−32=−x+−34
Step 2: Add x to both sides.
3x+−32+x=−x+−34+x
4x+−32=−34
Step 3: Add 3/2 to both sides.
4x+−32+32=−34+32
4x=34
Step 4: Divide both sides by 4.
4x4=344

Suppose y varies with x. Write a direct variation equation that relates x and y. Then find the value of y when x=10
Answers
Answer:
y = 1.5xy = 15 when x = 10
Step-by-step explanation:
A direct variation equation is of the form ...
y = kx
for some constant k. We can arbitrarily choose k=1.5, so our equation is ...
y = 1.5x
For x=10, the value of y is ...
y = 1.5·10 = 15

An object is moving at a speed of 9 kilometers every 6.5 years. Express this speed in inches per day. Round your answer to the nearest whole number.
Answers
Answer:
The object is moving at 149 inches per day.
Step-by-step explanation:
The speed can be converted from km/y to in/d taking into account that:
In 1 kilometer we have 39370.1 inches and in 1 year we have 365 days, hence:
[tex] V = \frac{9 km}{6.5 y}*\frac{39370.1 in}{1 km}*\frac{1 y}{365 d} = 149 in/d [/tex]
Therefore, the object is moving at 149 inches per day.
I hope it helps you!

Determine the slope of each line:
Answers
Answer:
a=(2/5), b = (-2,6)
Step-by-step explanation:
well slope formula is rise/run. So for the first one you start at the point rise 2 run 5 and you reach the endpoint. That is how you know you got the correct slope. (2/5)
For the second one you start at the first point and you cannot go up because it is a negative slope you run 6 till you hit the other point go down 2. Since you go down 2 that would make it -2. (-2,6)

Karen has 2/3 of her juice box left. Her brother drinks 3/4 of that. How much of the juice box does her brother drink?
Answers
Answer:
1/2 of the juice box
Step-by-step explanation:
We see that Karen has 2/3 of her juice box left. Her brother drinks 3/4 of that leftover 2/3.
First, remember that "of" in mathematics usually means to multiply. Here, since the brother drank 3/4 of the 2/3, we multiply the two:
(3/4) * (2/3) = (3 * 2) / (4 * 3) = 6 / 12 = 1/2
We understand this as 1/2 of the entire thing.
So, Karen's brother drank 1/2 of the juice box.

rachel states that -5.5 is an integer because it is negative. is she correct why or why not
Answers
Answer:
Rachel is not correct
Step-by-step explanation:
It is true that the set of integers includes negative numbers, where the sets of whole or natural numbers do not. However, any rational, irrational, or real number can be negative. -5.5 is a rational number, but it is not an integer, because it has a fractional part.
