Answer:
7*40=7 group of 4 ten
7 groups of 4 tens=28 tens
28 tens = 280 seats on the bus
Step-by-step explanation:
A school has 7 buses. Each bus has 40 seat
1 bus = 40 seat
To find the number of seats on 7 buses we multiply the number seat of each bus with total number of buses
7 buses = 40 * 7 = 280
40 can be written as 4 tens
7*40=7 group of 4 ten
7 groups of______tens= ________tens
7 group of 4 tens
we add 7 groups of 4 tens , 4 +4+4+4+4+4+4 = 28 tens
7 groups of___4___tens= ____28____tens
_____tens = _____ seats on the bus
28 tens = 28 * 10 = 280 seats on the bus
Answer:
x = -5
Step-by-step explanation:
-9(x+3) = -9x-27
Add 27 onto both sides and get -9x = 45
Divide -9 on both sides and you'll see that x = -5 because 45/-9

Answer:
2 pieces
Step-by-step explanation:
Given
![Length = 1\frac{2}{3}m](https://tex.z-dn.net/?f=Length%20%3D%201%5Cfrac%7B2%7D%7B3%7Dm)
![Pieces = \frac{3}{4}m](https://tex.z-dn.net/?f=Pieces%20%3D%20%5Cfrac%7B3%7D%7B4%7Dm)
Required
Calculate the number of pieces
To do this, we have to divide the length of the wood by the length of each piece.
Represent this with x
![x= \frac{Length}{Pieces}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7BLength%7D%7BPieces%7D)
![x= 1\frac{2}{3}/\frac{3}{4}](https://tex.z-dn.net/?f=x%3D%201%5Cfrac%7B2%7D%7B3%7D%2F%5Cfrac%7B3%7D%7B4%7D)
Convert mixed numbers to improper fraction
![x= \frac{5}{3}/\frac{3}{4}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B5%7D%7B3%7D%2F%5Cfrac%7B3%7D%7B4%7D)
Change division to multiplication
![x= \frac{5}{3}*\frac{4}{3}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B5%7D%7B3%7D%2A%5Cfrac%7B4%7D%7B3%7D)
![x= \frac{20}{9}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B20%7D%7B9%7D)
![x = 2.22](https://tex.z-dn.net/?f=x%20%3D%202.22)
