Step-by-step explanation:
7 + 3 = 10
+ 679 - 2056 = -1377
- 398 + 1 = -397
-23 - 237 = 260
2 - 6 = -4
-2 × 3 × -4 = 24
absolute value of -36 = 36
6 + 4 = 10
- 5928 - 965 = -6893
215 × 212 + 212 × 314 = 112148
(15 + 5) ÷ (15 + 5) = 20 ÷ 20 = 1
-457 + 1 = -456
- 218 -1 = -219
Answer:
The solution is in the attached file
A) C + A = 630
B) 2C + 5A = 2,910 Multiplying A by -2
A) -2C -2A = -1,260 Then adding it to B
B) 2C + 5A = 2,910
3A = 1,650
A = 550
A) C + 550 = 630

Answer:
The number of desktop internet users are 3 times more than the number of mobile internet users.
Step-by-step explanation:
We are given the following in the question:
Number of mobile internet users = 400,000,000

Number of desktop internet user =

Comparison of values:

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.
He has enough memory space to download a song that will use 0.12 gigabytes of memory
The memory capacity of new cell phone = 1.5 gigabytes
The memory capacity that already used = 1.35 gigabytes
The remaining space = The memory capacity of new cell phone - The memory capacity that already used
Substitute the values in the equation
Here we have to use the subtraction
The remaining space = 1.5 - 1.35
Subtract the terms
= 0.15 gigabytes
The size of the song = 0.12 gigabytes
We know 0.15 > 0.12
Hence, he has enough memory space to download a song that will use 0.12 gigabytes of memory
The complete question is
Devin has a new cell phone that holds 1.5 gigabytes if memory for music. He has already used 1.35 gigabytes of the memory. Will he have enough space to download a song that will use 0.12 gigabyte of memory? Explain.
