Answer:
2(x+5)
Step by Step explanation:
Since sum means the answer of an addition problem, that means it would be x+5. and since it is twice that, it would be 2*x+5, which we would then write as 2(x+5) so it could be easier to read and understand.
The answer is 2.5 because the point is on -1.5, so -1.5+4=2.5
Answer:
2
Step-by-step explanation:
5*2=10
10+10=20
or
5*x+10=20
10-10=0
20-10=10
5*x=10
5/5=0
10/5=2
x=2
Answer:
The pencil cost $0.05 and the pen cost $1.05.
Step-by-step explanation:
Let, the price of the pencil is $ .
Given that the pen costs a dollar more than the pencil,
So, the price of the pen=$+1.
Therefore, ++1=1.10
, 2+1=1.10
, 2=1.10–1
, 2=0.10
, =0.10/2
, =0.05
The pencil cost $0.05 and the pen cost $1.05.
