Answer:
Gummy bears $3.20/lbs
Jelly beans $7.50/lbs
Step-by-step explanation:
For this we will substitute gummy bear price for "x" and jelly bean price for "y" which creates this system (also assuming there is no sales tax involved):
1.8x + 0.6y = 10.26
1.2x + 1.5y = 15.09
Then once solved, answers come out to be (x,y) = (16/5,15/2) which is (3.2,7.5)


So, yes! Both fractions are equivalent.
Answer:
15
Step-by-step explanation:
7-(-1) is 8
8 divided by 4 (x or “run” of slope) is two
Two times five (y/rise of slope) is ten
5 (from original point -1,5) plus 10 is 15
(7,15)
Answer:
86cm³
Step-by-step explanation:
The area of the triangle is 1/2(b)(h)*2. The 1/2 and 2 cancel out as we’re doubling the small triangle to make the big triangle. Then you just multiply it times the length of the prism. So the formula ends up:
2.5*4.3*8=86cm³
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for <em>x</em>
- Subtract 5x on both sides: -2y = 10 - 5x
- Divide both sides by -2: y = -5 + 5/2x
- Rewrite: y = 5/2x - 5
