Answer: $0.27
<u>Step-by-step explanation:</u>
7a + 11b = 1.47
7a = 1.47 - 11b
Make a table. Choose values for b starting at $0.01 and solve for "a".
The value of "a" must terminate at the hundredths place since we are working with money.
You will discover that a = 0.10 and b = 0.07
The cost of 2 apples and 1 banana is:
2a + b
= 2(0.10) + (0.07)
= 0.20 + 0.07
= 0.27

Answer:
x= 2
or it's 0
Step-by-step explanation:
2.8 x
----- = ---- = (2.8)(17.4)=27.52(x)
27.52 17.4
49=27.52(x)
--------------
(27.52) (27.52)
2=x
or:
2.8/27.52= x/1.74
2.8(1.74)=27.52(x)
5=27.52(x)
0=x
89/100 as a precent is is 89% because if you change 89/100 to a decimal you get .89 and then you multiply that by 100 (or just move the decimal over 2 places to the right) and you will get 89% make since? and its the same way if your going from % to decimal except you divide by 100( or move the decimal over 2 places to the left) so to a percent is right and to a decimal is left. easy right?
