The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports a

harina [27]

Answer:

$80 billion

Step-by-step explanation:

From the graph, we have the following:

$United\ States = -110$

$Denmark = -30$

$China = 120$

$Germany = 40$

$Spain = 30$

Required

Determine the difference in US and Denmark exports

The difference is calculated as thus:

$Difference = Denmark - United\ States$

This gives:

$Difference = -30 - (-110)$

$Difference = -30 +110$

$Difference = 80$

Hence, the difference is $80 billion

The ratio of money in Obi's wallet to Rudy's wallet one day was 5:2.

mamaluj [8]

Answer:

The amount that Obi initially had was £20

Step-by-step explanation:

Let

x ----> amount that Obi initially has

y ----> amount that Rudy has

we know that

$\frac{x}{y} =\frac{5}{2}$

$x=2.5y$ ----> equation A

$x-20=y-8$

$y=x-20+8$

$y=x-12$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$y=(2.5y)-12$

solve for y

$2.5y-y=12\\1.5y=12\\y=8$

Find the value of x

$x=2.5(8)=20$

therefore

The amount that Obi initially had was £20
