Answer:
$15.00
Step-by-step explanation:
Suppose 1 rose bush costs r dollars,
Suppose 1 geranium costs g dollars.
Here are 2 equations:
1)6r+14g=146
3r+7g=73
2)r+7g=57
r=57-7g
Put 2) in 1)
3(57-7g)+7g=73
171-21g+7g=73
98=14g
g=7
r=8
7+8=$15.00
Hope I helped!
Put them all in to decimals so dived 1 by 5 and 32 by 100 then they will all be decimals and you can more essay compare them
Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
Length of the arc = radius x θ = 8 x 45 x π/180
= 8 x π/4 = 2π = 6.28 in ~ 6.3 in
An equation says that two things are equal. It will have an equals sign (assuming you know what that is) like this:
7+2=10-1
What the equal says on the left, is equal to the answer on the right.
Basically, it's a statement saying "equals that"
I don't fully understand your question, but I hope it helped you at least a little.
