If you would like to know how much do two apples cost, you can calculate this using the following steps:
o ... the cost of one orange
a ... the cost of one apple
1 * o + 1 * a = $1.05
2 * o + 3 * a = $2.75
_______________
o + a = 1.05 ... o = 1.05 - a
2 * o + 3 * a = 2.75
2 * (1.05 - a) + 3 * a = 2.75
2.1 - 2 * a + 3 * a = 2.75
a = 2.75 - 2.1
a = $0.65
o = 1.05 - a = 1.05 - 0.65 = $0.4
2 * a = 2 * 0.65 = $1.3
The correct result would be: Two apples cost $1.3.
Answer:
13.9
Step-by-step explanation:
To find the mean, add the two numbers and divide by two.
(13.9+13.9)/2=13.9
The ONLY multiple of 11 that's between 70 and 80 is 77 .
The answer is B you can just rephrase it into .4 < .5 idk if that made sense but yeah
Answer:
The smaller number is 5
Step-by-step explanation:
Let the smaller number be x
the other number is (17 -x) (we know they add up to 17)
2/3 of the bigger number is written as 2/3 (17 - x)
The smaller number is 3 less than that. (so subtract 3 to get x)
x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x
Check 2/3 x 12 - 3 = 8 - 3 = 5
