Answer:
x = 0
Step-by-step explanation:
[tex]\frac{3}{2}(\frac{7}{3}x + 1) = \frac{3}{2}[/tex]
To start, let's multiply each side by the reciprocal of [tex]\frac{3}{2}[/tex]. Multiplying a fraction by its reciprocal gives us 1, which will make the left side of our equation simpler.
[tex]\frac{2}3} * \frac{3}{2}(\frac{7}{3}x + 1) = \frac{2}3} * \frac{3}{2}[/tex]
[tex]\frac{2}{3} * \frac{3}{2} = 1[/tex], so we have:
[tex]1(\frac{7}{3}x + 1) = 1[/tex] or [tex]\frac{7}{3}x + 1= 1[/tex]
Next, we can subtract 1 from both sides to further simplify the left side:
[tex]\frac{7}{3}x + 1 - 1= 1 - 1\\\frac{7}{3}x=0[/tex]
Finally, we can multiply by the reciprocal of [tex]\frac{7}{3}[/tex] on both sides in order to isolate x on the left. Anything multiplied by 0 = 0, so now we have:
x = 0
7/2x + 3/2 = 3/2 <=> 7/2x = 0 <=> x=0

During a snowstorm, Noah tracked the amount of snow on the ground. When the
storm began, there was 1 inch of snow on the ground. For the first 4 hours of the
storm, snow fell at a constant rate of 3 inches per hour. The storm then stopped for 2
hours and then started again at a constant rate of 2 inches per hour for the next 6
hours. Make a graph showing the inches of snow on the ground over time using the data that Noah created
data that Noah collected.

Which number replaces the question mark? 19 11 11 ? 12
Answer:
i think 12
Step-by-step explanation:
Answer:
4 + 3 + 2 = 9
Step-by-step explanation:
You have to add all the numbers in the cube.
These are the following ones.
19 = 4 + 8 + 7
11 = 2 + 8 + 1
11 = 5 + 5 + 1
4 + 3 + 2 = 9
12 = 2 + 7 + 3

A local hamburger shop sold a combined total of 387 hamburgers and cheeseburgers on Thursday. There were 63 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?
Answer:
350 hamburgers
Step-by-step explanation:
Let x = the number of hamburgers sold
Let x - 53 = the number of cheeseburgers sold
x + x - 53 = 647
2x = 700
x = 350 hamburgers

Roberto bikes for 5.2 hours and covers a distance of 49.4 miles. Eileen bikes for 2.5 hours and covers a distance of 20.5 miles.
Assuming both Roberto and Eileen bike at a constant speed, who was biking faster and by how much? Select from the drop down menus to correctly answer the question. Choose... bikes faster than Choose... by Choose... mi/h.
Answer:
Roberto bikes faster than Eileen by 1.3 mi/h
Step-by-step explanation:
Roberto bikes at 49.4/5.2=9.5 mi/h
Eileen bikes at 20.5/2.5=8.2 mi/h
9.5-8.2=1.3
So Roberto bikes faster than Eileen by 1.3 mi/h

Find the distance between two points in the simplest radical form
The 2 points marked on the graph are :-
(2, 3) & (-7, -4)
Here,
=》x₁ = 2
=》y₁ = 3
=》x₂ = -7
=》y₂ = -4
Using distance formula....
√(x₂ - x₁)² + (y₂ - y₁)²
= √(-7 - 2)² + (-4 - 3)²
= √(-9)² + (-7)²
= √81 + 49
= √130 (in radical form)
= 11.4 (approx......in standard form)
♧ The distance between the 2 points is √130 units.

Solve 2 cot x = csc^2 x symbolically on the interval (0,2pi).
Answer:
x=pi/4, 5pi/4
Step-by-step explanation:
cot x = cos x / sin x, csc x = 1/sin x, so we have 2 cos x / sin x = 1/ sin^2 x. multiply both sides by sin^2 x to get 2 cos x * sin x = 1, divide both sides by 2 to get cos x sin x = 1/2, this would work for angles pi/4 and 5pi/4 (3pi/4 and 7pi/4 would make cos x sin x = -1/2) since cos x = sin x = sqrt(2)/2
Bryce has $16 more than Corey. Both have a combined total of $50. How much money does Bryce have.
Answer:
$33
Step-by-step explanation:
Let the amount of money Corey has be $x.
Amount of money Bryce have= $(x +16)
Total amount= $50
$x +$(x +16)= $50
2x +16= 50
2x= 50 -16
2x= 34
Divide both sides by 2:
x= 34 ÷2
x= 17
Amount of money Bryce have
= $(17 +16)
= $33
