Answer:

option A. x = -4/5 or x= 4/5

Step-by-step explanation:

The given equation is 100x² = 64

This is a quadratic equation.

Let  100x² = 64    ------(1)

Both the side of equation (1) is perfect squares.

taking  square root on both side of equation (1)

we get,

x² = 64/100

x=√64100

x = ±8/10

x = + 8/10 or x= -8/10

x = 4/5 or x = -4/5

Therefore the correct option is option A. x = -4/5 or x= 4/5

jeka94
Siince 2nd equation is already equal a, subsitute b-2 for a in the other equation

b-2-3b=28
-2-2b=28
add 2 to both sides
-2b=30
divide both sides by -2
b=-15
sub back
a=b-2
a=-15-2
a=-17

(a,b)

Select the objects that hold the same amount of liquid as a 98 fluid ounce jug
Tema [17]
To answer this question, you need to know how many fluid ounces are in a pint and in a quart.  None of the choices reflect 98 fl oz, so I showed the ones that would hold 96 fluid ounces.

1 cup = 8 fl oz
2 cups = 16 fl oz
1 pint = 2 cups, so 1 pint also equals 16 fl oz.

2 pints equal 1 quart, so 16 x 2 = 32 oz (the number of fluid ounces in a quart)

1 pint - 16 fl oz
1 quart = 32 fl oz

Choice A: 3 quarts x 32 =96 fl oz.
Choice B: 2 quarts x 32 = 64 fl oz
Choice C: 2 quarts  x 32 + 2 pints x 16 = 64 + 32 (96 fl oz)
Choice D: 1 quart x 32 + 8 cups x 8 = 32 + 64 (96 fl oz)
Choice E: 2 cups x 8 + 2 pints x 16 = 16 + 32 (48 fl oz)
