Write each sentence as an equation.
2 answers:
1) x + 16 = 58
2) 8x = 80
3) 12/x = 3
4) x - 8 = 21
Answer:
(The ones underlined are the equation)
1) Let the number be x
<u>x + 16 = 58 </u>
x = 58 - 16
x = 42
2) let the number be x
<u>x * 8 = 80 </u>
x = 80/8
x = 10
3) let the number be x
<u>12/x = 3 </u>
x = 12/3
x = 4
4) let the number be x
<u>x - 8 = 21 </u>
x = 21 + 8
x = 9

Answer:12
Step-by-step explanation:
1500m=1.5km so 1500 divided by 10= 150s it takes 150s to cover a distance of 1.5km
-3/2x
The rational expression would not be defined only when the denominator is divided by 0
That is:
2x =0
x = 0/2
x =0
Hence it would not be defined when x = 0.
Hope this helps.
Answer:
x=3
Step-by-step explanation:
f(x) = 2^x
Let f(x) =8
8 = 2^x
Rewriting 8 as 2^3
2^3 = 2^x
The bases are the same so the exponents are the same
3=x
