Answer:
x = 1
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
[tex]\frac{1}{2}x + \frac{3}{2} -2x = 2x - 2x[/tex] [tex]-\frac{3}{2}x + \frac{3}{2} = 0[/tex]Step 2: Subtract 3/2 from both sides.
[tex]-\frac{3}{2}x + \frac{3}{2} - \frac{3}{2} = 0 - \frac{3}{2}[/tex] [tex]-\frac{3}{2}x = -\frac{3}{2}[/tex]Step 3: Multiply both sides by -2/3.
[tex]-\frac{3}{2}x * -\frac{2}{3} = -\frac{3}{2} *- \frac{2}{3}[/tex] [tex]x = 1[/tex]Step 4: Check if solution is correct.
[tex]\frac{3}{2} + \frac{1}{2}(1) = 2(1)[/tex] [tex]\frac{3}{2} + \frac{1}{2} = 2[/tex] [tex]\frac{4}{2} = 2[/tex] [tex]2 = 2[/tex]Therefore, x = 1.

The velocity is the vector quantity. So, the direction in the space will not change.
Its velocity was 475 km/ minute northward. Then the correct option is C.

A vending machine randomly dispenses gumballs of three flavors: orange, grape, and cherry. If the machine currently contains 20 orange, 12 grape, and 7 cherry gumballs, what is the least number of gumballs the machine must dispense in order to ensure that three orange gumballs have been dispensed
Answer:
22
Step-by-step explanation:
Find the worst case scenario.
Worst case:
12 grape gumballs, 7 cherry gumballs, and 3 orange gumballs.
12 + 7 + 3 = 22
The answer is 22 gumballs.

At the beginning of the season, MacDonald had to remove 5 orange trees from his farm. Each of the remaining trees produced 210 oranges for a total harvest of 4179 oranges.
he initial number of trees was 204.
How to find the initial number of trees?The first step to finding the initial number of trees is to write an equation that represents the situation.
T is equal to the initial number of trees.5 trees were removed = t - 5Each tree produces 210 oranges = (t-5) (210)The total of oranges is 41,780 = (t-5) (210)= 41,780Solve the equation:(t-5) (210)= 41,780t-5= 41,780 / 210 t-5 = 198.95t = 198.95 + 5t = 203.9
This number can be rounded as 204.

Step-by-step explanation:
The difference in ratio units is 1, which corresponds to a difference in fruit count of 6. So the total of 7 ratio units must represent 7×6 = 42 pieces of fruit.
Find the time it would take, in hours, to travel 50 miles.
Answer:
1 hr at the speed of 50 mph
Step-by-step explanation:
If you went 50 mph it would be 1 hour. 100mph = 30min.
The time it will take to cover a given a given distance of 50 miles, assuming a speed of 20 miles per hour is 2 hours 30 minutes
Given Data
Distance = 50 miles
We Need another parameter speed, this will help us determine the exact time it would take to travel given the distance
Let us assume a speed of 20 miles per hour
We know that the expression relating speed, distance and time is given as
Speed = Distance/Time
Substituting we have
20 = 50/t
solving for t we have
t = 50/20
t = 2.5 hours
This is the same as 2 hours 30 minutes

Graph a line that contains the point (-5,-3) (−5,−3) with a slope of -2
What's the answer please help??
Answer:
See below and attached graph.
Step-by-step explanation:
The slope-intercept form of a straight line equation is y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
With a slope of -2, we can write:
y = -2x + b
To find b, enter the given point (-5,-3) and solve for b:
y = -2x + b
-3 = -2(-5) + b
-3 = 10 + b
b = -13
The equation becomes: y = -2x -13

There are 22 animals in the barn. Some are ducks and some are oxen. There are 72 legs in all.
How many of each animal are there?
Answer:
14 oxen8 ducksStep-by-step explanation:
Let x represent the number of oxen. Then the number of ducks is 22-x and the number of legs is ...
4x +2(22 -x) = 72
2x +44 = 72 . . . . . . . simplify
x +22 = 36 . . . . . . divide by 2
x = 14 . . . . . . . . . subtract 22; the number of oxen
22-x = 8 . . . . . the number of ducks
There are 8 ducks and 14 oxen in the barn.

What is the value of x? Round to the nearest tenth, if necessary. X = 4 x = 5 x = 6. 2 x = 9. 4.
You can use the Pythagoras theorem to get the value of x.
The value of x is given by
Option C: x = 6.2
What is Pythagoras theorem?The Pythagoras theorem:
If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
Using the above theorem to find the value of x for the given figureRefer to the figure attached below.
The triangle BAD is right angled triangle (one angle is 90 degrees).
The length of CD is 13 - x units.
Thus, we have:
[tex]|AD|^2 + |DB|^2= |AB|^2\\\\Length(AD)= \sqrt{169-81} = \sqrt{88} = 2\sqrt{22}[/tex]
For triangle ACD, we have:
[tex]|AC|^2 +|CD|^2 = |AD|^2\\|AC| = \sqrt{(2\sqrt{22})^2 - (13-x)^2} = \sqrt{-81 -x^2 - 26x}\\[/tex]
For triangle ACB, we have;
[tex]|AB|^2 = |AC|^2 + |CB|^2\\81 = (-81-x^2 +26x) + x^2\\\\x = \dfrac{162}{26} = \dfrac{81}{13} \rm \: units \approx 6.2 \: \rm units[/tex]
Thus,
