Answer:
Beatrice's age is 34
Step-by-step explanation:
Beatruce = B
Andrew = B+2
Chris= B-3
B+(B+2) +(B-3 )= 67-B
3B-1 = 67-B
2B -1 = 67
2B= 68
B = 34
Beatrice is 34
Andrew is 36 (34+2)
Chris is 31 (34-3)
36+31 = 67
8 as that means what two of the same number makes up , in this case 64. 8x8=64
1 1/9
To figure out how much walnuts to a pound of dried fruit you’d need to do proportions. So we cross multiply:
2/3 = X
—————- —————-
3/5 = 1
You multiply diagnols 2/3 x 1 = 2/3
3/5 times x is 3/5x.
2/3 = 3/5x. Isolate the variable. Divide 3/5 on both sides cancel out 3/5. 2/3 divide by 3/5 is 2/3 x 5/3 which is 10/9 which equals 1 1/9.
So for 1 lb of dried fruit you need 1 1/9 lb of walnuts to maintain the same mixture
