The number of permutations of the 4 different letters, taken two at a time, is given by:
T) -7x+10y=20. M) -3x+y=-2 - ,
2(8x-5y)=35(2) -1(x+y)=-6(-)
-7x+10y=20. -3x+y=-2
16x-10y=70. -x-y=6
9x=90. -4x=4
[x=10] [x= -1]
-7(10)+10y=20. -3(-1)+y=-2
-70+10y=20. 3+y=-2
10y=90. [y= -5]
[y=9]
Answer:
The answers are A, C, & D.
Step-by-step explanation:
A: the 34 would have an imaginary 0 behind it, so then it would become 340, which is greater than 304.
B, C, D: same logic as A
1200 + 150 = 1350 (if one day and one use)
Budget is 3600
We can use the crane 16 times
Explanation:
Budget is 3600 and 1200 + 150 (16) = 3600
