Yes you can! Say you have 5(2 + x) + 3x. The answer would be 10+8x because when you use the distributive property you will end up getting 5*2 5*x and once you multiply, it's obvious 5 times 2 is 10 and 5 times x will equal 5x. Then you add 5x and 3x and get 8x. So, the simplified expression here is 10+8x. When you have this as an answer it's proving your answer right. You can without using the distributive property. We can have 10+5x+3x and it will be your simplified expression. It's the same thing with equations too.
Answer: c(p) = 0.59*p
All we do is multiply the price per pound (0.59) by the number of pounds (p). In this case, we don't know how many pounds there are. So we leave p as is. If for instance, we had 10 pounds, then we'd replace p with 10. The variable is simply a placeholder for the unknown number.
Answer:
angle 3 = angle 6
angle 1 = angle 5
angle 2 + angle 5 + angle 6 = 180°
3/8y = 9/24 since 3*3=9 and 8*3=24
4 = 64/16 since 16*4=64
3z/x = 9z/3x since 3z*3=9z and x*3=3x
Answer:
Slope m = -5/8
Step-by-step explanation:
5x + 8y = 16
Making y as subject of formula
8y = -5x + 16
Dividing each term by 8
8y/8 = -5x/8 + 16/8
y = -5x/8 + 2
Comparing with y = mx + c
Where m = slope and c the y intercept
Slope m = -5/8
