Answer: 1
Step-by-step explanation: you need to get “like terms” by themselves. So to start, you can subtract 3x from both sides. Since the right side contains 3x and you are subtracting 3x, it will cancel on the right hand side, leaving you with the equation: 5x-4=1. Now, since the 4 is just 4, it does not fit in with the 5x. So, you need the 4 on the other side with the 1 because they are alike! So you will add 4 to both sides in order to cancel out the minus 4 on the left. Leaving you with 5x=5. You want to find what x stands for, so now since 5 and x are multiplying, we will divide both sides by 5 because we want x by itself! This leaves you with x=1.
It’s like 24 if your asking how much 4% of 600 is.
Answer:
B
Step-by-step explanation:
the product (2x² - 3x - 8)(3x² + 5x + 1) is required
multiply each term in the second factor by each term in the first factor.
= 2x²(3x² + 5x + 1) - 3x(3x² + 5x + 1) - 8(3x² + 5x + 1) ← distribute
= 6 + 10x³ + 2x² - 9x³ - 15x² - 3x - 24x² - 40x - 8
collecting like terms gives
6 + x³ - 37x² - 43x - 8 → B
Answer:
Part A: the dependant variable is how many hours he works mowing lawns.
the independent variable is that she earns $7 per hour.
Part B:(1,7) 1 hour working for $7
(2,14) 2 hours working for $14
(3,21) 3 hours working for $21
Part C: Y=7h (h represents the number of hours she works)
Step-by-step explanation:
I'm not 100% sure about part A I have not done this in a while but here you go
hope this helps
Answer:
283.5km
Step-by-step explanation:
Given data
Speed= 63km/h
Time= 4.5hours
We know that speed= Distance/time
Make distance subject of the formula
DIstance= speed*time
Distance= 63*4.5
Distance= 283.5km
Hence the distance is 283.5km
