Select the property of equality used to arrive at the conclusion. if 1/3 x=5 then x=15 the multiplication property of equality t

REY [17]

If we take both sides of the equation $\frac{1}{3} x=5$ and multiply either expression by 3, the equality becomes

$3\cdot\frac{1}{3}x=3\cdot5\\x=15$

Multiplication of both sides of an equality by the same number keeps the equality true, and we call this property the multiplication property of equality.

Use the graph to estimate the height of a jugglers ball that has been in the air for 1.5 seconds

strojnjashka [21]

Answer:

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Step-by-step explanation:

we are given height equation as

$h=-16t^2+25t+5$

where

h is the height in feet of a Juggler's ball after t seconds

now, we can plug t=1.5

$h=-16(1.5)^2+25(1.5)+5$

we can solve for h

$h=42.5-16\cdot \:1.5^2$

$h=42.5-36$

$h=6.5$

So,

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet
