Answer: Choice B
rose bush: $10, shrub: $4
=========================================
Work Shown:
x = cost for one rose bush
y = cost for one shrub
Rob's equation: 8x+5y = 100
Amy's equation: 8x+8y = 112
Subtract the equations straight down (match terms)
8x - 8x = 0x = 0, x terms go away
5y-8y = -3y
100-112 = -12
After those three subtractions, we end up with this new equation: -3y = -12
That equation solves to y = 4 when you divide both sides by -3
Use this value of y to find x
8x+5y = 100
8x+5(4) = 100 ... replace y with 4
8x+20 = 100
8x+20-20 = 100-20 .... subtract 20 from both sides
8x = 80
8x/8 = 80/8 ... divide both sides by 8
x = 10
We end up with x = 10 and y = 4 pairing up. The two equations, when graphed, cross at the location (10,4). One rose bush costs $10 and one shrub costs $4.
1/8
If you can make the bottom numbers (denominator) The same that you can use subtract the top numbers like normally
9 times 5 equals 45 so yes
Answer:
4 4√3
Step-by-step explanation:
Answer:
36°
Step-by-step explanation:
The image of the question is obtained online and attached to the solution of this question.
The tent pole is the line in the middle of the triangle and it is stated explicitly in the question that this tent pole bisects the angle that the two sides make with each other at the top.
So, the angle that the tent pole makes with each side = (72°/2) = 36°
Hope this Helps!!!
