6. A restaurant can seat 100 people. It has booths
1 answer:
<u>Answer:</u>
The expression matches the situation is 4x + 6y = 80
<u>Explanation:</u>
We are given a total of 100 seats which is the maximum amount a restaurant can seat
And there are booth with 4 and table with 6 seating
so let no. of 4 seat booths be x and tables with 6 seats be y
We can form the equation as 4x + 6y = 100
We are also given that 5 of the 4 seat booths are full so this means
45 = 20 seats out of 100 are full
so left ones can be written in the form of an expression 4x + 6y = 80

Scientific notation implies that all the zeros are taken away and replaced with a 10 raised to whatever appropriate power would be necessary to make the number in scientific notation equal to the original number.
In the number 780,000,000, we can see that there are 7 zeros, but the number before the zeros has two digits, so we need to tuck the decimal point in there, because the number has to be between 1 and 10 for math reasons.
7.8 ... but what do we raise it to? We know it has to be 10, but to what power? Well, we just count how many places to the left the decimal point has traveled. From the original number, the decimal point shifted 8 places to the left, so that is the number that we will raise the 10 to.
The final number looks like this:
780,000,000 in scientific notation is <span>
