Answer:
$2.40
Step-by-step explanation:
First, you would do 22.70 minus 3.50, to get 19.20.
Then, you would divide 19.20 by 8, to get 2.4.
So, if each pineapple was the same price, each pineapple would be $2.40.
Answer:
1.8 cm
6.3 cm²
Step-by-step explanation:
AC⊥BC
BD=BC=x
- (x+5)²+x²=7²
- x²+10x+25+x²=49
- 2x²+10x- 24=0
- x²+5x-12=0
- x=1.8
BC= 1.8 cm
Area of ABC= 1/2*1.8*7= 6.3 cm²
Y=2x+1
x is the input, so the 2x will make it twice the input, and the +1 will make it one more, therefore y(the output) is one more than twice the input :)
