Answer:
x= -6
Step-by-step explanation:
3x+4= 2 (x - 1)
3x+4= 2x -2
Subtract 4 from both sides of the equation
Simplify
Subtract 2x from both sides of the equation
Simplify
= -6
Answer:
Question 1: Diameter of 14ft
Question 2: It has a radius of 6ft
Question 3: it has a diameter of 19ft
let me know if this helps!!
Step-by-step explanation:
Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:
85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96
Ok so whit the data that we got we can proceed like this:
[(-2, 7), (1, 0)]
d = 2/3
Now lets find the difference between x and y terms.
The difference of -2 and 1 is 3,
The difference of 7 and 0 is 7.
x = 3
y = 7
Now Multiply it by two thirds.
2/3 * 3 = 2
2/3 * 7 = 4.7
So the answer is the second option. Hope this helps
