4x+10=-26
Subtract 10 to both sides:
4x=-36
Divide 4 to both sides:
x=-9
Answer:
1.60 L of 10% solution
0.40 L of 35% solution
Step-by-step explanation:
If x = amount of 10% saline solution, and y = amount of 35% saline solution, then:
x + y = 2
0.10x + 0.35y = 0.15(2)
Solve with substitution:
0.10x + 0.35(2 − x) = 0.15(2)
0.10x + 0.70 − 0.35x = 0.30
0.40 = 0.25x
x = 1.60
y = 0.40

Answer:
m∠VST = 105°
Step-by-step explanation:
Two central angles are marked as having the same measure. The measure of the corresponding arcs are the same. The sum of all arc measures is 360°.
(-37x +2) +2(-27x -3) = 360
-91x -4 = 360
-91x = 364
x = -4
m∠VST = (-27(-4) -3) = 105 . . . . degrees
Answer:
2nd option.
Step-by-step explanation:
3(8 - 4x) < 6(x - 5)
24 - 12x < 6x - 30
-12x - 6x < -30 - 24
-18x < -54
x > 3
