Answer:
a) x = -1.5
b) x = 1
Step-by-step explanation:
For problem a, you can start by subtracting 3x from both sides to gather all the like terms together:
7x + 5 = 3x - 1
-3x -3x
4x + 5 = -1
Next, to get the coefficients on one side, you subtract 5 from both sides:
4x + 5 = -1
-5 -5
4x = -6
Now, you divide by 4 on both sides to isolate x:
x = -6/4 = -1.5 --- > x = -1.5
For problem b, you start by subtracting 3x from both sides(kinda like problem a):
5x + 12 = 3x + 14
-3x -3x
2x + 12 = 14
Next, you can subtract 12 from both sides, isolating the "x term".
2x + 12 = 14
-12 -12
2x = 2
Lastly, you can divide by 2 to get x:
x = 1
Answer:
70% are medium-sized jerseys.
Step-by-step explanation:
The complete question is:
The football team has a total of 20 jerseys. There are 14 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys? nothing% are medium-sized jerseys.
Solution:
The information provided is:
- The football team has a total of 20 jerseys.
- There are 14 medium-sized jerseys.
Compute the percentage of medium-sized jerseys as follows:


Thus, there are 70% medium-sized jerseys.
All you have to do is multply 4 by all the sides of the cube
We have to break each degree in terms of 90
A) 
Which is in third quadrant, therefore sine is negative hence

B) 
Which is in third quadrant, therefore cosine is negative hence

C) 
Which is in third quadrant, therefore tangent is positive hence

D) 
Which is in third quadrant, therefore cosec is negative hence
not defined
E)
Which is in third quadrant, therefore secant is negative hence
