Answer:
2) -32
Step-by-step explanation:
Basically just convert this into an equation:
Let’s use “x” as the result
“•” is the multiplication symbol
Double s: s•2
Subtract t from result: =x-2
So, s•2=x-2
Answer:
Step-by-step explanation:
A 36% discount means the selling price is (100-36)% = 64% of the original price.
$272 = 64% of x = 0.64·x
x = $272/0.64 = $425
Answer:
∠1 = 23°
Step-by-step explanation:
∠WXZ = ∠WXY + ∠YXZ
Note that ∠2 = 4∠1 ( angle 2 is 4 times angle 1 )
Hence
4∠1 + ∠1 = 115
5∠1 = 115 ( divide both sides by 5 )
∠1 = 23°
