DCAB would be 100. I'm pretty sure DCAB would be 100 because if DDAC is 20 that means the letters D,C, and A are 5. So if D,C, and A are all equal to 5 then B is equal to 85.
Answer:
(x+9)(x-9)
Step-by-step explanation:
Lets first number is x, so second number is (x+32).
The sum of these numbers is 186 so
x+(x+32)=186
2x+32=186
2x=154
x=77
second number is x+32=77+32=109
Answer: numbers are 77 and 109
Answer:
-15
Step-by-step explanation:
6.8(6.7 – 7.2) – 2(4.6 + 1.2)
The first step in PEMDAS is to do whatever's in the parenthesis. So, this would be the 6.8 bit.
6.8 times 6.7 is 45.56 and then 6.8 times 7.2 which is 48,96
Now we can also do the second set of parenthesis. 2 times 4.6 is 9.2, and 2 times 1.2 is 2.4
The equation now reads- (45.56 - 48.96) - (9.2 + 2.4)
All we have to do is evaluate what's in the parenthesis, the first set equals -3.4 and the second set equals 11.6
So, now our expression reads, -3.4 minus 11.6 which equals -15
