Answer:
Step-by-step explanation:
Solving
5x + -2y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
5x + -2y + 2y = 12 + 2y
Combine like terms: -2y + 2y = 0
5x + 0 = 12 + 2y
5x = 12 + 2y
Divide each side by '5'.
x = 2.4 + 0.4y
Simplifying
x = 2.4 + 0.4y

Express the product of (2x + 3) and (x - 5)
Answer:
Here is the answer......
Answer:
2x² - 7x - 15
Step-by-step explanation:
Given
(2x + 3)(x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x - 5) + 3(x - 5) ← distribute parenthesis
= 2x² - 10x + 3x - 15 ← collect like terms
= 2x² - 7x - 15

Step-by-step explanation:
Segments AB,DC, and EC intersect at point C. Angle DCE measures 148. Find the value
Answer:
x = 16°
Step-by-step explanation:
We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°
∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)
∠ACD = x, ∠DCE = 148, ∠ECD = x
substituting the respected values for the angles gives:
x + 148 + x = 180
2x + 148 = 180
subtracting 148 from both sides:
2x + 148 - 148 = 180 - 148
2x = 32
Dividing both sides by 2, to get x:
2x/2 = 32/2
x = 16°

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

Alma is going to walk through the park from Point A to
Point B
What distance will she walk?
HELPPPPPPPPPPPPPPPPP
Answer:
I think the answer is 200 feet
Step-by-step explanation:
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A right-angle triangle has sides with lengths 200 ft and 200 ft.
By Pythagoras theorem, we have
H² = P² + B²
H² = 200² + 200²
H² = 40000 + 40000
H² = 80000
H = 200√2
H = 282.84 ft
Alma is going to walk through the park from Point A to Point B is 282.84 ft.

Calculate the length of the unknown side of this right-angled triangle.
9 cm
8 cm
Answer:
the length of the unknown side of the right angle triangle is 1 cm
Step-by-step explanation:
The computation of the length of the unknown side of the right angle triangle is shown below:
= √9^2 - √8^2
= √81 - √64
= 9 - 8
= 1 cm
Hence, the length of the unknown side of the right angle triangle is 1 cm

6^2-4+1 i dont know if you need to simplify even more but if you do
36-4+1 32+1 31
i hope this helps you!
Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!
I hope this helps.
