Answer: choice A
Step-by-step explanation:
the transposed matrix would be
5 3
2 -1
so
5*5+2*2=29
3*5+2*-1=13
5*3-2*-1=13
3*3+-1*-1=10
which gives us the answer
29 13
13 10
Answer:
15
Step-by-step explanation:
you add all of them up and you get your answer
Answer:
15:10
Step-by-step explanation:
Method 1: 5 lots of 3:2 →5 × (3:2) = (5×3) : (5×2) = 15:10
Method 2: 3/2 × 1 → 3/2 ×5/5 = 3×5 2×5= 15:10
boys: 15
girls: 10
Answer:
x=27.8
Step-by-step explanation:
first, you need to find y. 2y-5=65. 65+5 is 60 and you are left with 2y=70. to get the 2 off of the y you divide everything by 2. 70/2 is 35 therefor y=35. Now you plug that into the other equation (2x+y) and get 2x+35 which is equal to segment 90.6 so 2x+35=90.6. subtract 35 on both sides and you have 2x=55.6. To get the 2 off the x, we divide everything by 2. all of that divided by 2 is x=27.8
