Answer:
t=-19/7
Step-by-step explanation:
you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7
we know that anything divided by itself is 1 so we get -19/7=t
This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.
Since 4^2=sqrt(16), we can rewrite it as that. In addition, as 2 is a factor of 16, we can rewrite it as sqrt(2)*sqrt(16/2)=sqrt(2)*sqrt(8). Crossing out the sqrt(2), we get sqrt(8) as our answer. To simplify it, we can note that 2^2=4 and 4 is a factor of 8 when multiplied by 2, so we get 2*sqrt(2)
Answer:
not equal because 2+5=7 and 1+5=6
Step-by-step explanation:
Answer:
(b) 950 km
(c) 90 litres
(d) $108
Step-by-step explanation:
Henry lives 95 km from work.
Number of km from home to work = 95 km
Number of km from work to home = 95 km
One day = 95 + 95 = 190 km
<u>Assuming he works 5 days a week.</u>
1 day = 190 km
5 days = 190 x 5 = 950 km
<u>Assuming he works 5 days a week.</u>
1 day = 18 litres
5 days = 18 x 5 = 90 litres.
<u>Assuming he works 5 days a week.</u>
1 litre = 120 cents
90 litres = 120 x 90 = 10800 cents = $108
