We can use a rule of three simple, direct proportion to solve this problem.
15 pounds correspond to $1.80, then the question is to find the price of one pound, the called unit rate. We state the rule of three:
15 pound ----> $1.80
1 pound -----> x
x = (1)(1.80)/15
x = 0.12
Therefore, each pound costs $0.12 that is the unit rate in pounds
First you need to write an equation or an inequality.
5+1.80x<=12
the x here is how many miles you are paying for, now you just solve for x.
5+1.80x<=12
-5 -5
1.80x<=7
/1.80 /1.80
x<=3.8
you can travel only three whole miles, you do not have enough money to go four full miles.
Answer:
A.m = -3
Step-by-step explanation:
This equation is written in point slope form
y-y1 = m(x-x1)
y +2 = -3(x – 7)
y - -2 = -3(x – 7)
The slope is -3 and the point is (7, -2)
Answer:
19
Step-by-step explanation:
one third of 57 is the same as saying 57 divided by 3 and if you do that then you get the answer above
Answer:
Step-by-step explanation:
The given equation is :
N=S(P-V)-F ...(1)
We need to solve the above equation for S.
Adding F both sides in equation (1)
N+F=S(P-V)-F+F
N+F=S(P-V)
Dividing both sides by (P-V). So,
So, the above is the expression for S.
