Travis has decided to budget his spending money. He can spend no more than $ 143.15 every month. He has also decided to spend 5.

dalvyx [7]

Answer:m<$23.09

Step-by-step explanation: This question is tricky as there are unexplained variables.

Travis plans spending $143.15 every month but only two expenses were given to us, so other possible expenses may or may not be expended in this particular month.

That’s why we must include an inequality here.

Okay, back to the question.

Travis plans spending 5.2 times movie money on video games, my kinda dude.lol

Hence, 5.2m=v

m=movie budget

v=video games budget

But m+v<=143.15, the total proposed budget. Let’s replace v with 5.2m,

We have,

m+5.2m<=143.15

6.2m<=143.15

m<=23.0887

(We’ll have to approximate to the nearest cent)

m<$23.09

What is the value of x in the equation 1/2x - 3/4 = 3/8 - 5/8

Kitty [74]

The answer

x = 1

step by step

$\frac{1}{2} x - \frac{3}{4} = \frac{3}{8} - \frac{5}{8} \\ \frac{1}{2} x = \frac{3}{8} - \frac{5}{8} + \frac{3}{4} \\ \frac{1}{2} x = \frac{3}{8} - \frac{5}{8} + \frac{6}{8} \\ \frac{1}{2}x = \frac{4}{8} \\ \frac{1}{2} x = \frac{1}{2} \\ x = 1$

Can someone please help me with this

CaHeK987 [17]

Alright!

To solve, all we need to do is subtract the area of the inner circle from the arear of the outer circle.

But first, we need to find the area of both

Key equation: πr²

π = 3.14

Inner cirle area = π13²

π13² = 530.66

Outer cirle area = π21²

I got 21 by adding 8 and 13: both added together makes the radius of the larger circle

π21² = 1,385.74

Now let's subtract.

1,385.74 - 530.66 = 855.08

The area of the blue is = 855.08 yards²
