Answer:
1 pear = $0.45
1 mango = 1.5
Step-by-step explanation:
8 pears + 5 mangoes = $11.10 ➡ 8p + 5m = 11.10
5 pears + 4 mangoes = $8.25 ➡ 5p + 4m = 8.25
multiply first equation by -4 and second one by 5
-4 ×(8p+5m) = 11.10 ➡ -32p - 20m = 44.4
5 ×(5p+4m) = 8.25 ➡ 25p + 20m = 41.25
add both equations up
-32p - 20m + 25p + 20m = 44.4 + 41.25
-7p = 3.15 ➡ p = $0.45
use this value to find the price of mango
5×0.45 + 4×m = 8.25 ➡ 2.25 + 4m = 8.25 ➡ 4m = 6 ➡ m = $1.5
Answer:
B. Between 200 and 400
Step-by-step explanation:
Rule of exponents means that you can subtract when they are divided
-5+7=2
7.8*10^2/3.1
Simplify
780/3.1= 251.612903
Answer:
see explanation
Step-by-step explanation:
Note there is a common ratio between consecutive terms of the sequence, that is
- 450 ÷ 15 = 13500 ÷ - 450 = - 405000 ÷ 13500 = - 30
Thus to obtain the next term in the sequence multiply the previous term by - 30
start with 15 and multiply by - 30
6 pies split up into 8 people would make 6÷8, or 6/8. if you simplify the fraction you would get 3/4, meaning everyone got 3/4 pie, or .75 pie.
The answer is C (x+14/x-2)
I just did this problem on a quiz about an hour ago and c was the correct answer
