Answer:

The question seems to be pointing towards a multiple choice response but I will do my best. The first equation would be 15x+12y=9.30 and the second would be 10x+4y=4.60, x represents flour and y represents sugar.
Hope this helps.
Answer:
E. - 7
Step-by-step explanation:
2x2-X2+5X-10-4=0
X2+5X-14=0
X2-2X+7X-14.=0
X(X-2). 7(X-2)=0
(X+7). (X-2)
X=-7, X=2
Three machines fill 40 boxes in an hour. One machine can fill 40/3 boxes in an hour. Following the second part of the problem, one machine would take 150/40/3 = 11.25 hours to fill 150 boxes. Machines and time are inversely proportional. Then, it would take 11.25 * 1/5=2.25 hours for 5 machines to fill 150 boxes.
Find a common denominator to subtract, so smallest common denimator between 7 and 3 is 21
multiply 4/7 by 3/3 and 2/3 by 7/7
12/21-14/21= -2/21
