Step-by-step explanation:
The given equation is : 3x-2(x+3)=4(x-2)-73x−2(x+3)=4(x−2)−7
On solving this equation and applying the distributive property, we have
⇒3x-2x-6=4x-8-73x−2x−6=4x−8−7
⇒x-6=4x-15x−6=4x−15
Combining the like terms like terms consisting of x are solved together and the constants are solved together,
⇒x-4x=-15+6x−4x=−15+6
⇒-3x=-9−3x=−9
⇒x=3x=3

Answer:
Equation: 190 = 6 + 23p
Answer: p = 8
Step-by-step explanation:
So first we have a total of $190 and regardless of how many people go, parking is going to cost $6 so that amount will be reduced from the total money they have for the amusement park. The rest left will go towards the tickets. That means the amount they have is $190-$6 = $184. 23 x the number of tickets = $184. You need to divide the 184 by 23 to get the number of tickets. Which is p in this situation. Therefore the answer for p would be 8. For the equation, you have 190 = 6 + 23p. Therefore those two is our answers.

What is the volume of a cylinder, in cubic ft, with a height of 9ft and a base diameter
of 16ft? Round to the nearest tenths place
Answer:
1809.6 cubic feet
Step-by-step explanation:
Use the formula for the volume of a cylinder, V = [tex]\pi[/tex]r²h
Plug in the height and radius:
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](8²)(9)
V = 1809.6
So, the volume of the cylinder is 1809.6 cubic feet
maria walks 22 feet, then goes another 40 feet on a path that makes a 70 degree angle with the path she was on. how far is she, in feet, from her starting location?
Answer:
132 feet
Step-by-step explanation:
22+60+70
The distance of the Maria from her starting location is 109.9 feet.
What is trigonometry?Right angle triangles are the focus of the mathematical field of trigonometry. Calculations involving specific functions of angles are the focus of trigonometry.
In trigonometry, the following six functions are frequently used: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (cosec)
Let's call the distance Maria is from her starting location "x".
The 70 degree angle forms a right triangle with the distance Maria walked initially (22 feet) and the distance she is from her starting location (x). We can use the trigonometric function tangent to find x:
tan(70°) = x/40
Multiplying both sides by 40, we get:
x = 40 tan(70°)
Using a calculator, we find that tan(70°) is approximately 2.7475. Multiplying by 40, we get:
x = 109.9
So Maria is approximately 109.9 feet from her starting location.

Write an equation in slope-intercept form for the line that passes through (1,9), and (3,5).
To write the equation of the line, we will use the point-slope formula.
To do this, we need a point and a slope.
We can find out slope by using the slope formula.
m = y₂ - y₁ / x₂ - x₁
So we have 5 - 9 / 3 - 1 or -4/2 which is -2.
Now let's use the point-slope formula.
y - y₁ = m(x - x₁)
Now substitute one of our points (x₁, y₁) into our formula.
So we have y - 5 = -2(x - 3).
Distributing the -2 gives us y - 5 = -2x + 6.
Moving the -5 to the right, we have y = -2x + 11.
So y = -2x + 11 is our equation.
A line segment has end points at (3, -5) and (4, 1) What is its length?
a. 9 units
b. 6.9 units
c. 9.2 units
d. 5 units
need an explanation if possible please.
Answer:
6.08units
Step-by-step explanation:
The distance between two points of a line is expressed as;
D = √(y2-y1)²+(x2-x1)²
Given the coordinates (3, -5) and (4, 1);
D = √(1+5)²+(4-3)²
D = √(6)²+(1)²
D = √36+1
D = √37
D = 6.08 units
Hence its length is 6.08units

Further, cost of trail mix = $4.50 per pound
The total amount of trail mix collected by all 4 children will be-
15 + 14 + 10 + 7
= 46
Thus, in total the children put 46 pounds of trail mix in their bags.
Hence, the total cost will be-
