Answer:
4 is the number.
Step-by-step explanation:
Take the missing number as x,
→ (x × 3) - 4 = (x × 2)
→ 3x - 4 = 2x
→ 3x = 2x + 4
→ 3x - 2x = 4
→ [ x = 4 ]
Hence, the number is 4.
First equation:
y=10x+150
y=25x
10x+150=25x
15x=150
x=10
so, 10 weeks
EDIT:
how many dollars dey save? dunno
jkkkkk
For John
150+10(10)=
150+100=
250
For Erin
They both equal
First of all, its the jack of diamonds. Well, the king is worth 10 or 13. The jack is worth 11 or 10. The 3 is worth either 3 or 5. Depending on what you mean by value, the expression could be 13+11+3 or 10+10+5.
Answer with Step-by-step explanation:
We are given that


a.We have to find g(f(x))


b.We can see that
f(x) is logarithm function and g(x) is linear function.
But , the composition function gof(x) is also logarithmic function.
The composition function gof(x) is 3 times the function f(x).
