Section 1:
using this format we can determine what the answer is:
42 105
—— • ——-
100 x
(the spacing may be off but imagine two separate fractions)
first multiply 100 by 105 to get 10,500
then divide by 42 to get 250
this means that sasha’s book has 250 pages
section b:
using the same formula we can solve this problem:
first we need to multiply 250 by 2 to get the total cost of both tickets
175 x
—— • ——
100 500
(again spacing may be off but think of two separate fractions)
then multiply 500 by 175 to get 87,500
then divide by 100 to get 875
to find the profit subtract 875-500
this means he will make $375 profit
conclusion:
sasha’s book has 250 pages
trevor will make $375 profit
this is the method my teacher taught me last year so it should be right, hope this helps and please mark brainliest!!

Step-by-step explanation:
190/55=3.4545
We want to calculate the following
Using the properties of exponents, we have that
So we have
So, if factor 10^-4 on the right side, we have
Note that
Then,
So we have that
Answer:
Price = 20, Amount = 14
Step-by-step explanation:
A = Amount of Mangoes
P = Price for 1 Mango
P = A + 6
280 = P * A
insert A+6 for P
280 = (A+6) * A
280 = 6A + A²
280=1*a^2+6*a | Vertausche beide Seiten der Gleichung.
1*a^2+6*a=280 | quadratische Ergänzung: ergänze auf beiden Seiten (3)^2
1*a^2+6*a+(3)^2=3^2+280 | Rechne 3 hoch 2 aus.
1*a^2+6*a+(3)^2=9+280 | addiere 9 und 280
1*a^2+6*a+(3)^2=9+280 | Fasse die rechte Seite mit Hilfe der binomischen Formel zusammen.
1*(1*a+(3))^2=289 | Auf beiden Seiten Quadratwurzel ziehen.
1*a+(3)=+-*289^0.5
1*a_1+(3)=289^0.5
1*a_1+3=289^0.5 | Ziehe die Wurzel aus 289
1*a_1+3=17 | -3
1*a_1=14

Answer:
2 1/12 days
Step-by-step explanation:
Time is the ratio of distance to speed.
(1200 mi)/(24 mi/h) × (1 day)/(24 h) = 25/12 day = 2 1/12 days
