6
Step-by-step explanation:
The only way the expression can be factored is if a -3 is pulled out...
-3(5t+2)
Answer:
30+4+0.7+0.05
Step-by-step explanation:
Because the expanded form is added the number.
3=30
4=4.
7=0.7
and 5=0.05 so all together is 30+4+0.7+0.05
Answer:
10
Step-by-step explanation:
let the number be n then half the number is 
n, then
n + n = 15
Multiply through by 2 to clear the fraction
2n + n = 30, that is
3n = 30 ( divide both sides by 3 )
n = 10
Thus the number is 10
Answer:
Yes, 500 texts.
Step-by-step explanation:
If you write out the equations, you can just set them up equal to each other and simplify.
A = .05x + 20
B = .07x + 10
.05x + 20 = .07x + 10 (subtract 10 from both sides)
.05x + 10 = .07x (subtract .05x from both sides)
10 = .02x (multiply both sides by 50
x = 500 texts
