Step-by-step explanation:
23+5=28 28÷2=14
Answer:440
Step-by-step explanation:
a is the unknown number
25% of a=110
25/100 x a=110
1/4 x a=110
a/4=110
Cross multiplying we get
a=110 x 4
a=440
V*t=S
V=3x10^8 m/s
S=7.5x10^6 m
t=S/V = 7.5x10^6 / 3x10^8 = 7500 000 / 300 000 000 = 0.025 s
Answer: 4p^2-2p
Step-by-step explanation:
Hello!
3x + 5 = x - 10
Solve for x by isolating the variable.
Subtract 5 from both sides:
3x + 5 - 5 = x - 10 - 5
3x = x - 15
Subtract x from both sides:
3x - x = x - x - 15
2x = -15
Divide both sides by 2:
2x /2 = -15 / 2
x = -15/2.
