Write the following as an expression: How much water do I need to add to l liters of pure alcohol to obtain a solution of 45% al

vredina [299]

Answer:

see below

Step-by-step explanation:

amount of water w

l liter of pure alcohol = 100% alcohol

solution is 45 % percent alcohol

total amount of fluid is w+l

(w+l)( .45) = l*.100

Distribute

.45w + .45 l = 1l

.45 w = 1l - .45l

.45 w = .55l

w = .55l / .45

w =11/9 l

Tasya [4]

Answer:

A.) (-1,-6) and (-3,-2)

Step-by-step explanation:

The given line segment has coordinates

(-1,6) and (-3,2)

The mapping for a reflection in the x-axis is

$(x,y)\to (x,-y)$

This implies that;

$(-1,6)\to (-1,-6)$

and

$(-3,2)\to (-3,-2)$

The correct choice is A.
