Answer:

It accelerated at 5 km/hr/s or the car was going 5 km/h faster each second.

The car was speeding up

Step-by-step explanation:

To find an estimated acceleration, you just take the speed it got to and divide it by the tie it took to get there

<em>s</em>/<em>t = a</em>        <---- where <em>s = </em>speed   <em>t = </em>time   <em>a =</em> acceleration

We know it was speeding up because it was at a red light so it was stopped. Then when it turned green, then the car would have started moving

8. What is the solution to 0,3(12x16)=0.4(12-3x)?​
kvasek [131]

Answer: False

Step-by-step explanation: First, you are going to multiply the numbers in the first set of parenthesis, getting 72. Now, have 72 take the place of 12x6 in the equation. Your new equation looks like this: 0.3 x <u><em>72</em></u> = 0.4(12-3).

Going off of step one, you will be doing the same thing with the second set, but you will be subtracting instead. You will get 9, and plug it place of the parenthesis. Your equation now looks like o.3 x 72 = 0.4 x <em><u>9.</u></em>

<em><u /></em>

Next, you will multiply the set of numbers on the left side of the equal sign, getting 21.6. You now have an equation of <em><u>21.6</u></em> = 0.4 x 9.

Going off of step 3, you are going to do the exact same thing we did in step 3. Multiply 0.4 and 9, and you will get 3.6. The equation now looks like 21.6 = <u><em>3.6</em></u>.

Now, the inequality is false because the left-hand side and right-hand side are two completely different numbers. A bigger number cannot be equal to a smaller number.

Hope this helps!
