please help! I need to solve it algebraically and if you can show your work/explain how you got the answer that would help a ton because I need that to!
Answers
The answer is x=-10
Step-by-step explanation:
the reasoning is you do the inverse or opposite of three to both sides so you add +3 to both sides so the -3 and the +3 would cancel out then you would add +3 to the integer -23 and get -20 next is you divide by 2 on each side so you 2÷2 which would cancel out and then -20÷2 which would equal -10
Hence the answer is x=-10
2x + (-3) - (-3) = -23 - (-3)
2x = -23 + 3
2x = -20
2x/2 =-20/2
x = -10

hey can yall please help me its 4'1 minuse 1'10
Answers
12 inches= 1 ft.
12(4)= 48 ; 48+ 1inch = 49 inches
1’10= 1 foot and 10 inches
1(12)= 12 + 10 = 22
49-22= 27 inches !
In other words, it's 2 feet, 3 inches
=================================================
Work Shown:
Convert the 4'1" to purely inches only
4'1" = 4 ft, 1 inch
4'1" = 4 ft + 1 inch
4'1" = 48 inches + 1 inch
4'1" = 49 inches
Note how 4 ft = 4*12 = 48 inches
-------------------
Through similar steps, you should find that 1'10", aka 1 ft 10 inches, is equivalent to 22 inches
Subtracting the two quantities gets us
(4' 1") - (1' 10") = (49 inches) - (22 inches) = 27 inches
Now convert that to the format "feet,inches".
27 in = 24 in + 3 in
27 in = (24/12 ft) + 3 in
27 in = 2 ft + 3 in
27 in = 2 ft, 3 in
27 in = 2' 3"

Which equations are equivalent to his weekly addition of 0.5 km and would correctly determine how many weeks it will take Hector to reach 10 km if he starts at 2.5 km and adds 0.5 km every week? Select all that apply. 0.5x + 2.5 = 10 0.5 – 2.5 = 10x 10 = 2.5 + 0.5x 2.5x + 0.5 = 10 2.5x – 0.5 = 10
Answers
Answer:
C. 10 = 2.5 + 0.5x
Step-by-step explanation:
A. 0.5x + 2.5 = 10
B. 0.5 – 2.5 = 10x
C. 10 = 2.5 + 0.5x
D. 2.5x + 0.5 = 10
E. 2.5x – 0.5 = 10
Total distance Hector covers = 10 km
Distance he has covered = 2.5 km
Distance he covers per week = 0.5 km
Let
x = number of weeks
The equation is given by
2.5 + 0.5x = 10
It can also be written as:
10 = 2.5 + 0.5x
10 - 2.5 = 0.5x
7.5 = 0.5x
x = 7.5/0.5
x = 15 weeks
Answer:

What do cos and sin mean?
Answers
Answer and Step-by-step explanation:
These two terms (pronounced as Sine and Cosine) are used to solve for the sides and angles of a triangle in Trigonometry.
They are functions revealing the shape of a right triangle.
Sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.
Cosine is also a trigonometric function of an angle. The cosine of an angle is the relation of the length of the side that is adjacent that angle, to the length of the longest side of the triangle.

I believe your answer is:

Here’s why:
For any set of parallel lines given, they will never intercept because of the same slope that they share. This means that if the slopes are different (if the lines are not parallel), they will eventually have a point of intersection.»»————- ★ ————-««
