Answer:
cos beta = 3 /5 ............
First you need to find the cost of 1 can of nut:
let x represent the number of cans
4x=$9
divide both by 4
x=2.25
meaning 1 can costs $2.25
$2.25×7
=$15.75
meaning the cost of 7 cans is $15.75
Answer:
p(8p + 7)
Step-by-step explanation:
Factorise is when you find the product of the question before taking away the brackets.
so, if you go p(8p + 7), you times p with everything inside the brackets giving you 8p^2 + 7
therefore, the answer is p(8p + 7)
Hope this helped :)
There are 10 coins in total, and 2 of which are quarters. so our fraction form is 2/10, which we can reduce down to 1/5
