You need to write it out such as number 8 would be 10x10x10x10 so for every number on top you multiply the number by itself
1 way : 10d + 2d
another way: 5d + 5d + 2d
Answer:
a. 12 minutes
b. 34 minutes
Step-by-step explanation:
Here, we are told that Ima has driven 5 minutes before Polly started driving
So if Ima has driven for x minutes , polly would have driven for y minutes but the difference between x and y is 5
So mathematically;
x = y + 5
a. 17 = y + 5
y = 17-5 = 12 minutes
b. x = 29 + 5
x = 34 minutes
C. 6 pens for $6.42
