Armando reads 7/8 pages, since u said ''times'' that calls for multiplication so jasmine reads 1 3/4 and Armando reads 1/2 times that so that means 1/2 * 1 3/4 = 7/8. So in conclusion, Armando reads 7/8 pages total.

Hope this helps and if it does, happy studying and don't forget to mark as brainliest.

The Commutative Property of Addition

Step-by-step explanation:

They have a common denominator of 12

21/12+6/12+20/12+4/12+3/12+6/12=60/12=5 cups

or you could group ingredients with the same denominators

7/4+1/4+1/2+1/2+5/3+1/3=

8/4+2/2+6/3=

2+1+2=5

The Commutative Property of Addition says the order of the numbers doesn’t change the outcome.

Answer:

x =  \frac{ - 24 \pm \sqrt{ - 288} }{4}  \\  =  \frac{ - 24 \pm \sqrt{ ( - 1) {(12)}^{2} (2)} }{4} \\  =   \frac{ - 24 \pm \sqrt{ - 1}  \sqrt{ {12}^{2} } \sqrt{2}  }{4} \\  =   \frac{ - 24 \pm i 12\sqrt{2}  }{4} \\  =-\frac{24}{4}\pm \frac{i12\sqrt{2}}{4}\\=  -  6  \pm \: i3 \sqrt{2}
