Answer:
15x = -75
x = -5
Step-by-step explanation:
Set the first part about the product of 15 and x equal to -75.
Then, divide both sides by -15 to get y = -5.
Answer:
The number is = 16
Step-by-step explanation:
Given:
Twice the sum of a number and 2 is equal to three times the difference of the number and 4.

Answer: find x
Tan(30)=20/x
X= 20/ tan(30)
Tan(30) =0.577
X= 20/ 0.577
X=34.66
Find Y
Sin(30)=20/y
Y=20/sin(30)
Sin(30)=0.5
Y=40

Answer: I think the length is 60.25 yd and the width is 19.75 yd
Step-by-step explanation: I formed a equation using the information that has been given.
Width : X
length : 1 + 3x
equation : (1 + 3x) + x = 80
Then, I added the like pairs ( 3x+x ). After, I subtracted 1 from 80 and got 79. Then I divided 79 and 4 (79/4) to get 19.75, which is my x value. later, I substituted the x value to the equation and received my answer.
