Solve to find x 3/4 (5x-3) + 8 = 17
Talja [164]

Answer:

3

Step-by-step explanation:

3/4 (5x -3)+8=17

3/4 (5x -3) = 17 - 8 = 9

(5x -3) = 9 * (4/3)= 36/3 = 12

5x = 12 + 3 = 15

Gabe​ Amodeo, a nuclear​ physicist, needs 60 liters of a 60​% acid solution. He currently has a 50% solution and a 70% solution.
FromTheMoon [43]

Answer:

Gabe needs 20 liters of the 40% solution.  

He also needs 40 liters of the 70% solution.

Step-by-step explanation:

Equation:


acid + acid = acid


0.40x + 0.70(60-x) = 0.60*60


40x + 70*60 - 70x = 60*60


-30x = -10*60


x = 20 liters


Gabe needs 20 liters of the 40% solution.  

He also needs 40 liters of the 70% solution.

What is the area of this whole figure in square units?
IrinaK [193]
Well, it is a good and interesting question

Such areas could be calculated in a single shoot and also by dividing the whole shape into other shapes and the total area would be the sum of these areas

I prefer the way of a single shoot ...

The figure represents a trapezoid:
its lower base = 21 units
its upper base = 12 units
the normal height between them = 8 units

NOW

The area of a trapezoid = [(sum of bases' lengths) ÷ 2] * height
                                       = [(12 + 21) ÷ 2] * 8 = 132 sq units


Hope that helps
