Answer:

t = 13.2 s

Step-by-step explanation:

Given that,

An athlete ran the 100 meter sprint in 13.245 seconds. We need to round off the time to the nearest tenth.

Here, t = 13.245 s

In order to round off to the nearest tenth, thousandths place and hundredth place gets eliminated.

So, t = 13.2 s

So, time is 13.2 seconds.

4.35 * 2.29 = 9.9615 or 10

The chicken salad costs $9.9615 or $10, whichever you need.

A discounted amusement park ticket costs $12.95 less than the original price (p). Write and solve an equation to find the origin
Elena-2011 [213]
P = the original price of the ticket.

Let x =  the discounted price.
The discounted price IS $12.95 less than the original price. Therefore
x = p - 12.95

Add 12.95 to each side.
p = x + 12.95

Answer:
The equation is
p = x + 12.95
where
p = original price
x = discounted price

Solve for x<br><br> 2x - 1 - 1 = x - 3 - ( -5 + x )
Nana76 [90]

Answer:

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x−1−1=x−3−(−5+x)

2x−1−1=x−3+−1(−5+x)(Distribute the Negative Sign)

2x−1−1=x+−3+(−1)(−5)+−1x

2x−1−1=x+−3+5+−x

2x+−1+−1=x+−3+5+−x

(2x)+(−1+−1)=(x+−x)+(−3+5)(Combine Like Terms)

2x+−2=2

2x−2=2

Step 2: Add 2 to both sides.

2x−2+2=2+2

2x=4

Step 3: Divide both sides by 2.

2x

2

=

4

2

x=2
