Answer:
1.x=15
2.<A=29
Step-by-step explanation:
(2x-1)+(3x+9)+(6x+7)=180
2x-1+3x+9+6x+7=180
11x+15=180
11x=180-15
11x=165
x=165/11
x=15
2.<A=2x-1
<A=2*15-1
<A=30-1
<A=29
Solution:
we are given that
6 people can sit together at 1 rectangular table.
2 tables are placed together, 10 people can sit together.
14 people can sit if three tables are put together.
It mean we get a sequence
6,10,14..........
So its making an arithmetic progression, where
First term
Common difference
Number of terms=number of table
As we know the nth term is given by the formula

Hence 402 people can sit.
Answer: 50
Step-by-step explanation:
Let X represents his total weekly pay check
Hence, 70% of X = 35
70/100 × X =35
0.7 × X =35
0.7X =35
X = 35 ÷ 0.7
X = 50
X which is 50 is Alex 100% weekly pay check.
a quotient is the answer to a division problem
so the answer would be 100 /20 = 5
Answer:
since 200 is 10 times 20 you can just multiply 4 by 10 to get 200÷5
