<span>Julia is X+5

</span><span>x+x+5=31
</span>
Now we just solve the equation

2x=31-5
x=26/2
x=13 years old (Babs' age)

and we know that julia is 5 years older this gives us the conclusion that.

13+18=31

Answer:

The full budget has a total value of $160,000

Step-by-step explanation:

This is a simple ratio problem and can be solved using the Rule of Three property. The Rule of Three is used to compare two ratios and find the missing part. In this case the ratios would be the following.

$\frac{64,000}{40 percent} = \frac{x}{100 percent}$

$\frac{64,000 * 100 percent}{40 percent} = \frac{x}$

$\frac{6,400,000}{40 percent} = \frac{x}$

$160,000= \frac{x}$

So now we know that 100% (The full budget) has a total value of $160,000.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

$a^{2} + b^{2} = c^{2}$

$a^{2} + 7^{2} = 18^{2}$

$a^{2}$ + 49 = 324

$a^{2}$ = 275
