Answer:
x = 4.7
Step-by-step explanation:
30x - 140 -(x - 4)
Multiply the -1 into (x - 4)
30x - 140 - x + 4
Add/subtract
29x - 136 = 0
+136
Answer:B and E
It is B and E because it’s exponent matches the equation. In B, there are 2 fives and the exponential form shows 5 to the power of 2. In E, there are 6 sevens and the exponential form shows 7 to the power of 6.
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
