Y=4 and the slope of the problem would be -5
You have to add 15+30+12+18...
So she started with $75.
Hoped I helped!
Good luck!
Answer:
Head: 113.04 in³
Basketball: 33.5 in³
Step-by-step explanation:
suppose Ronnie's head and basketball are spheres
V = 4/3πr³
Head: V₁ = 4/3 * 3.14 * 3³ = 113.04
Basketball: C = 2πr
r = C / 2π = 12.57 / 6.28 = 2.00 (it's a small ball :))
V₂ = 4/3 * 3.14 * 2³ = 33.49
Answer:
9. -4x+19y-7
10. 7x+20
Step-by-step explanation:
9. To simplify this expression, simply combine like terms. Add all of the terms with the x variable together, then the terms with the y variable, then the constant terms. I will show this step by step, but usually you do not have to show this work. The order of the terms does not matter.
x variable terms: (4x-8x)+7y-2+6y+6y-5= -4x+7y-2+6y+6y-5
y variable terms: (7y+6y+6y)-4x-2-5=19y-4x-2-5
constant terms: (-2-5)-4x+19y=-4x+19y-7
10. To simplify this expression, expand all terms and then combine like terms. The first term can be expanded by multiplying each term in the parentheses by 2.
Expand terms: 2(5+3x)+(x+10)= 10+6x+x+10
Now, you can combine like terms as done on the last problem. Note that I got rid of the parentheses in the second term, as they did not matter (since there was no term in front of them).
x variable terms: (6x+x)+10+10=7x+10+10
constant terms: (10+10)+7x=7x+20
