7z + 10 - z = 8z - 2(z - 5)
7z + 10 - z = 8z - 2z + 10
6z + 10 = 6z + 10
6z - 6z = 10 - 10
0 = 0
Therefore, 7z + 10 - z = 8z - 2(z - 5)
This is quite basic actually,
208 kmh equals 208,000 meters per hour
This is because a km equates to 1000 meters.
To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
total income = 5x
If we let total income be y, our equation is further simplified into,
y = 5x
111/210 = about 53%. 52.85714% of 903 is 477.3 students. of course you can't have a fraction of a student so it is 477 students
Answer:
Equations weren't provided in the question but my answer is 3T=108
Step-by-step explanation:
t is oranges sold on Thursday.
f is oranges sold on Friday
If she sold the amount she sold on Friday is equal to 2x the amount on Thursday: 2t=f. But the total of 108 is both days added together. So she sold 2t on friday and 1t or ton thursday than you add it up like so: 2t+t=108 becasue 108 is the total. But 2t+t=3t so you get the final equation as 3t=108
