Equation 1 : x + y + z = 3.25
equation 2 : 12x + 2y + z = 9.50
equation 3 : 2x + 4y + 5z = ??
u would multiply equation 1 by -12.....take that result and add it to equation 2....this eliminates x.
u would multiply equation 3 by -6...take that result and add it to equation 2....this eliminates x
Answer:
Breaking up the multiplicand 8 into (5+3) allows us to apply the associative property of multiplication. See below.
Step-by-step explanation:
5*7 = 35. We want the product 8*7. Note that 8 = 5+3. Thus, 8*7=(5+3)(7) = 35 + 21, or 56.
Answer:
580 is spent on onions and potatoes
Step-by-step explanation:
The grocery store ordered 47 bags of onions, and 1 bag costs 2.
It also ordered 167 bags of potatoes, and the bag costs 3.
47 bags onions X 2 render 94
162 bags potatoes X 3 render 486
94 (cost of onions) + 486 (cost of potatoes) = 580
