Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
Answer(s):
Solution:
<u>We know that:</u>
- Brookie = x dollars
- Benji = x + (20% × x)
<u>Solution:</u>
To see which expression has been used, we will need to simplify the expression.
- Benji = x + (20% × x)
- => Benji = x + (20/100 × x)
- => Benji = x + (2/10 × x)
- => Benji = x + (0.2 × x)
- => Benji = x + (0.2x)
- => Benji = x + 0.2x
- => Benji = 1.2x
Looking at the options, Option A and Option B matches with our result.
