Answer:
2 2/3 lbs
Step-by-step explanation:
Convert Alya's mixed number to an improper fraction
3*1+1 = 4/3
multiply 4/3 times 2/1
4*2 = 8
3*1 = 3
8/3 - convert back to mixed number
8/3 = 2 2/3
3x+2(3x-3)=2
9x-6=2
9x=8
X=8/9
Answer: C
Step-by-step explanation:
Your answer is correct! When you multiply 2 matrices, the inner dimensions have to be equal. If they are equal, the resulting dimensions would be the outer dimentions.
(<u>3</u>×4)(4×<u>5</u>)
Since the inner (bolded) dimensions are the same, in this case 4×4, we know these matrices can be multiplied.
Since these matrices can be multiplied, the product will be 3×5, the underlined outer dimensions.
Answer:
The range would not change
Step-by-step explanation:
If we replaced one of the 7s with a 5, we still have a 7. The range will be the highest number minus the lowest number (7 - 1 = 6). So the range would still not change because we still have another 7.
Answer:
C
Step-by-step explanation:
First use distribution
4(3x+y)= 12x+4y
and
-2(x-5y)= -2x+10y
combine the 2 answers
10x+14y
