Hi there!
345*28923+808(2829)
The first step put the problem into 2 parts, the first part is 345*28923
The second part is 808(2829)
The parentheses means to multiply that number that it touches.
Add the final 2 answers.
345*28923 = 9,978,435
808(2829) = 2,285,832
Now, add the answers.
9,978,435 + 2,285,832 = 12,264,267
Hope this helped!~
System: x + y = 44; x = 2y + 2
Solve with substitution: x = 30; y = 14
x + y = 44
x = 2y + 2
Substitute 2y + 2 for x
2y + 2 + y = 44
3y + 2 = 44
Subtract 2 on both sides.
3y = 42
y = 14
Now substitute back in.
x + 14 = 44
Subtract 14 on both sides.
x = 30
Answer:
38.46 (Rounded: 38.5)
Step-by-step explanation:
67.32-2(14.43)=38.46
Answer:
16
Step-by-step explanation:
2+6=8
8+10=18
18+14=32
6+4=10 10+4=14
an+1=an+(2+4n)
a7=a6+26=72+26=98
a8= a7+30= 98+30=128
a9=a8+34=128+34= 162
a10=a9+38= 162+38=200
a11=a10+42= 242
a12=242+46=288
a13=288+50= 338
a14=338+54= 392
a15=392+58= 450
a16= 450+62=512
