(sorry didn't know how to do the squared sign )
Answer:
Exact-$1,536 Estimate-$1,500
Step-by-step explanation:
26+22=48
48 x 32 = 1,536
Estimate-1,500 or 1,540
Exact-1,536
Answer:
Step-by-step explanation:
first find the slope using the above points then use the slope formula to calculate the slope
substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b
substitute the slope and the value for b into the equation to get the answer
Let's say Jackson's age now is x.
In 20 years, (so 20+x), Jackson seven years ago will be 2/5ths of that age.
So 2/5(20+x)=x-7
Then you solve the equation
8+2/5x=x-7
15=3/5x
x=25
Jackson is 25 years old.
Let's check our answer! In 20 years, Jackson will be 45. 7 years ago, he was 18. 2/5 of 45 is 18. Our answer is correct!
