"<span>Bob spent twice as much as James, who spent four times as much as Nava"

Bob:     b</span>
James: j
Nava:   n

Bob spent twice as much as James:           b=2j
<span>James spent four times as much as Nava: j=4n</span>

<span>Bob and James together spent $180:        b+j=180
but we have:                                                b=2j
                 </span><span>                                                -------------------
</span>                                           <span>                          2j+j=180
</span>                                           <span>                           3j=180      >>      j=60$
</span>                                           <span>                                                      b=2j=120$</span>
Recall this: <span>j=4n >>>>    60=4n >>>>>n=15$</span>


SO far we calculated how much everyone spent

I hope that helps!

Let's say that Bob is x and James is y

x + y = 180
x = 2y

2y + y = 180
y = 60.
James spent 60 dollars.

Musya8 [376]

Answer:

3000 is your answer

Step-by-step explanation:

The 3 in the hundreds place if the number 587,349 has a value of 300. This 300 is 1/10 the value of the number you're looking for, so if x is the number you're looking for, then

300 =  \frac{1}{10} x

300 \times 10 =  \frac{1}{10} x \times 10

3000 = x

x is your answer.

Ivan

Answer:

Given expressions are equivalent.

Step-by-step explanation:

Given expression:

4 (x + 3) + 2x and 6 (x + 2)

Find:

Given equivalent expressions or not

Computation:

By taking LHS

4 (x + 3) + 2x

4x + 12 + 2x

Each side of the equilateral triangle shown is 3 inches long. What is the height of the triangle?
rodikova [14]

•  measure of the side:   s = 3 in


You can find the height  h  by this formula:

          s · √3
h  =  ————
              2

          3 · √3
h  =  ————
              2

           3√3
h  =  ————  in     (exact value)
             2


Using  √3 ≈ 1.73,

           3 · 1.73
h  ≈  —————
                2

           5.19
h  ≈  ————
             2

h ≈ 2.60 in   (approximate value)


I hope this helps. =)
