Answer:
x = 7/3
Step-by-step explanation:
3(x-4)=-5
Distribute
3x - 12 = -5
Add 12 to each side
3x -12+12 = -5+12
3x = 7
Divide by 3
3x/3 = 7/3
x = 7/3
X': (0,-6)
Y':(10,4)
Z':(-3,-1)
For a 45-45-90 angle the hypotenuse is s * square root of 2
so the hypotenuse is 14 * square root of 2 or 19.8

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
Hey there!☺
To solve, we will need to evaluate:
We're not done yet because we need to simplify 13673/20:
Hope this helps!☺
