Answer:
Step-by-step explanation:
So since the question is no completed. The only way you can answer this is by simplifying it which is not the same as the value of x. It would be 3x+8
x+3x= 4x
Because there is a invisable 1 in front of the X. Hope this helps!
Answer:
#4= 1
#5= A=9,216
B=360
Step-by-step explanation:
number five x equals 9 and y = 1,024 so it's asking us that if x = 81 what would y = and to get 81 you need to multiply 9 by 9 so all you have to do is multiply 1024 by 9 to get 9,216 so y = 9,216 and the same thing goes for B
Answer:
5 and 6
Step-by-step explanation:
let the 2 consecutive integers be n and n + 1 , then
3(n + 1) = 5n - 7
3n + 3 = 5n - 7 ( subtract 3n from both sides )
3 = 2n - 7 ( add 7 to both sides )
10 = 2n ( divide both sides by 2 )
5 = n and n + 1 = 5 + 1 = 6
the 2 consecutive integers are 5 and 6
