Answer:
$3.00
Step-by-step explanation:
5x + 3y = 30 - - - - - 1 x 4
3x + 4y =29 - - - - - -2 x 3
--------------------------------------------
20x +12y = 120 - - - - 3
9x + 12y = 87 - - - - - 4
--------------------------------------------
3-4
20x - 9x= 120 - 87
11x = 33
X= 33
11
X = 3
Step-by-step explanation:
a.) All real numbers x greater than 2
===> X > 2
b.) 6 more than a number k is less than or equal to 12
===> 6+k =< 12
I would take 84 times 3 for the three tests which gives you 252. I would then subtract the two test they took which is the 90 and 82 for a total of 172. 252-172 =80. The lowest score would be an 80
Answer:
A. 7 burritos for $51.50
Step-by-step explanation:
22.50/3=7.50
1 burrito cost $7.50
2 burritos will cost $15.00
2×7.50=15
5 burritos will cost $37.50
5×7.50=37.50
4 burritos will cost $30.00
4×7.50=30.00
However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50
