8.75 + 0.50 =9.25 dollars spend but she has 16 dollars so 16 - 9.25 = 6.75 dollars left
All u have to do is plug in the values
68) -(4q) = -(4*-3) =-4*3= -12
70) 5P-6= (5*5)-6 =25-6= 19
72) 7q-7p= 7(-3)-7(5) = -21-35= -56
74)2q/(4p) = 2(-3)/4(5)= -6/20= -3/10
My math teacher time me is easier to do it after
Let's start with 17 seats and just bikes. That is 34 wheeles. Now, each bike we replace with a go-kart will add 2(because we take away 2 and add 4). We need to add 14 wheels. This means we will replace 7 bikes with go-karts. 7 go-karts (28 wheels) and 10 bikes (20 wheels) is the answer.
Answer: 136 units squared
Step-by-step explanation:
I will assume this is a rectangular prism since it isn't specified.
The surface area of a rectangular prism: SA = 2(lw+lh+wh).
Plugging in your dimensions: SA = 2(7*2 + 7*6 + 2*6) = 2(14+42+12) = 2(68) = 136 units squared.
