Answer:
Mrs Chauke's annual income= $384480
Step-by-step explanation:
Mrs Chauke earns 32040 every month and we need to find the annual income which is how much she earns in a year. 12 months in a year, so
12 times 32040 is 384480
Answer:
She has 607 nickels
Step-by-step explanation:
40 x 15 + 7 = 607
First you'll need to solve for x. To do this, put both equations equal to each other
6x-12=-9x+3
Add 9x to both sides
15x-12=3
Add 12 to both sides
15x=15
Divide both sides by 15
x=1
Next, substitute x into one of the equations to find y
y=(6*1)-12
y=6-12
y=-6
The important thing to know to solve this problem is how many meters are in kilometers: 1 kM = 1000 M
Using that information, we can find out how long the race is in meters
5 kM = 5000 M
Because the dad's average step is about 1 meter long, he well need to take 5000 steps to finish the race
