Question

Combine like terms to create an equivalent expression.

-3.6-1.9t+1.2+5.1t

Answer:

3.2t - 2.4

Step-by-step explanation:

Given;

-3.6 - 1.9t + 1.2 + 5.1t

Combining like terms means bringing terms that have "t" together and separately, those that don't have "t" together. i.e

=> − 1.9t + 5.1t - 3.6 + 1.2

=> 3.2t - 2.4

Therefore, the equivalent expression is;

3.2t - 2.4

Answer:

The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles

Step-by-step explanation:

We are given

Bethel Park is 28 miles directly west of Jeanette

10.3 miles directly south of Pittsburgh

We can draw diagram

we can see that this is triangle

so, we can use Pythagoras theorem

and we get

$x^2=28^2+10.3^2$

now, we can solve for x

$x=\sqrt{28^2+10.3^2}$

$x=29.834miles$

So,

The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles

The time it takes to transport goods has __________ over time, causing trade to __________. A. increased . . . decrease B. decre

fenix001 [56]

Answer: C. decreased . . . increase.

As technology is advancing it requires less time and effort to do almost anything. So for tranportation as well i think it will take less time to do it. Thus logically people would want to trade more because the transport goods take less time. I guess?

Percents

Nana76 [90]

Answer:

As a percent: 115%

As a decimal: 1.15

As a fraction: $\frac{23}{20}$

Step-by-step explanation:

<u>Percentages</u>

Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.

Thus, he is really paying 100%+15% = 115% of the original price.

To express a percentage as a decimal, we just divide by 100:

115% = 115/100 = 1.15

The same division should be simplified instead of operated to express the percentage as a fraction:

115% = $\frac{115}{100}$

Simplifying by 5:

115% = $\frac{23}{20}$

Summarizing:

As a percent: 115%

As a decimal: 1.15

As a fraction: $\frac{23}{20}$
