Number 6 hopefully it helped
Answer:
288 pi
Step-by-step explanation:
Answer:
22 and 7
Step-by-step explanation:
Let x and y be the two numbers we are looking for:
The statement “their sum is 29” means x + y = 29
The statement “their difference is 15” means x - y = 15
we get this system:
x + y = 29 (1)
x - y = 15 (2)
Let’s solve it :
(1) + (2) ⇒ x + y + x - y = 29 + 15 ⇒ 2x = 44 ⇒ x = 44/2 = 22
Now we replace x by 22 in equation (1) :
22 + y = 29 ⇒ y = 29 - 22 = 7
Answer: The system consists of parallel lines
Step-by-step explanation:
Given system of lines :
Substitute in , we get
, which is not true.
That means , system has no solution.
i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]
Answer:
3 jeans and 5 sweaters
Step-by-step explanation:
This is a solid guess
However, this is a straight forward question.
175 she has to spend all of it.
To make it an even number you minus 25.
Than you have 150, minus another 50.
You have 5 more clothes to buy, and $100 left.
You use the rest to buy sweaters, therefore spending all the money and getting 8 clothing.
