7000 because if the hundred next to the thousand is below 5 the number will be the same
eg: 3200 the answer will be 3000
but if the number is 5 and higher the thousand will be one extra
eg 1: 3521 the answer will be 4000
eg 2: 4809 the answer will be 5000
Answer:
-a will be greater than -b because for example, when a=2 and b=5, -a=-2 and -b=-5
<span>6u^9+(8u^9+4v)
= </span><span>6u^9 + 8u^9 + 4v
= 14u^9 + 4v</span>
Answer:
x = -1
Step-by-step explanation:
2x + 3(2) = 4
2x + 6 = 4 Multiply 2 and 3 to get 6.
2x = -2 Subtract 6 from both sides to isolate 2x.
x = -1 Divide both sides by 2 to find x.
Answer:
m∠3 = 57° → proved down
Step-by-step explanation:
The given is:
- Lines
and 
- Lines
and 
- m∠1 = 123°
We want to prove that m∠3 = 57°
∵ // and is the transversal → given
∴ m∠1 = m∠2 → corresponding angles
∵ m∠1 = 123° → given
∴ m∠2 = 123° → equality of two corresponding angles
∵ // and is the transversal → given
∴ m∠2 + m∠3 = 180° → interior supplementary angles
∵ m∠2 = 123° → proved
∴ 123 + m∠3 = 180 → subtract 123 from both sides
∴ m∠3 = 57° → inverse addition property
