Answer: 9

Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9

So the answer would be 9

Hope this helps!

Annete is suveyeing people in the city about their interest in a new shopping mall. She found that 180 people, or 37.5% of those

VLD [36.1K]

she surveyed "x" amount, which is the 100%, but we also know that 180 is the 37.5%, so

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 180&37.5 \end{array}\implies \cfrac{x}{180}=\cfrac{100}{37.5}\implies 37.5x=18000 \\\\\\ x=\cfrac{18000}{37.5}\implies x=480$
