Answer:
a. 12.5
Step-by-step explanation:
Scale factor of ∆LMN to ∆XYZ = 2:5
To find length of side ZX, set the ratio of the corresponding sides of interest equal to the scale factor.
Thus:
ZX corresponds to NL = 5
NL:ZX = 2:5
5:ZX = 2:5
5/ZX = 2/5
Cross multiply
5*5 = ZX*2
25 = ZX*2
Divide both sides by 2
25/2 = ZX
12.5 = ZX
ZX = 12.5
You need to isolate the "x" in both inequalities
5x + 7 ≤ -3 Subtract 7 on both sides
5x ≤ -10 Divide 5 on both sides
x ≤ -2
3x - 4 ≥ 11 Add 4 on both sides
3x ≥ 15 Divide 3 on both sides
x ≥ 5
This is your simplified inequalities:
5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A

(the question was cut off so I used the information I had) Hope this helped!
Answer:
The answer is -2
Step-by-step explanation:
you subtract common numbers, so:
5s - 3s = 2s
Then,
-6 + 2 = -4
You would then get
2s - 4
divide -4 by 2 which is -2
and your answer is s = -2
