Plug 5 into (9x-58) and plug x into 2x, then multiple 5 by 2(x)
3. if you buy 2 you will be down 4 cups. but if you buy 3 you will go over so the answer is 3
I = inches.
2.5*i= the answer
All I need to know is the actual number of inches so that i can give you the exact answer
A unit rate is basically the same as a unit cost like for example if you buy 10 dogs for 1000 dollars total then its 1000/10 and each dog is $100. since its 100 for each dog its 100/1 so the unit cost is $100
Answer:
Step-by-step explanation:
Multiply the equation by 4
5x - 2 + 2 = 2*(3y + 2)
5x +0 = 2*3y + 2*2
5x = 6y + 4
5x - 6y = 4 --------------------(I)
Multiply the equation by 6
2*(7y + 3) = 3x + 2*7
14y + 6 = 3x + 14
14y = 3x + 14 - 6
14y = 3x + 8
-3x + 14y = 8 ------------------------(II)
Multiply equation (I) by 3 and equation (II) by 5 and then add
(I)*3 15x - 18y = 12
(II)*5 <u>-15x + 70y = 40</u> {Now add}
52y = 52
y = 52/52
y = 1
Substitute y =1 in equation (I)
5x - 6*1 = 4
5x - 6 = 4
5x = 4 +6
5x = 10
x = 10/5
x = 2
