G is the answer because if you set x as the value of B, then x+(x+10)+(x+30)=180 so x=46.67. then you add 10 to that because the value of A is 10 more than B

The cost per week of running a boarding house is partly constant and partly

patriot [66]

Answer:

the cost of running the boarding

house for 600 students is N61,000

Step-by-step explanation:

Let C represents cost

K1 represents first constant

K2 represents second constant

C= k1+k2n

3500 = k1 + 25 k2............. Eqn(1)

6000= k1 + 50 k2 .............. Eqn(2)

Subtract eqn(1) from eqn(2)

2500= 25k2

K2= 2500/25

K2= 100

To get k1 from eqn(1)

3500 = k1 + 25 k2

Substitute the value of k2

3500 = k1 + 25 (100)

3500= k1 +2500

K1= 3500- 2500

K1= 1000

The equation connecting them;

C= 1000+ 100n

The cost of running the boarding

house for 600 students is

n= 600

C= 1000+ 100(600)

C= 1000+60000

C= N 61,0000

On the coordinate grid of a map, Josie's house is located at (2,7). Her school is located at (-5,5). If each map unit equals one

To find the distance you would use the distance formula which is:
$d = \sqrt{(x2-x1)^{2}+(y2-y1)^{2}} = \sqrt{(2-(-5))^{2}+(7-5)^{2}}$

This equals:
$d = \sqrt{(7)^{2}+(2)^2} = \sqrt{49+4} = \sqrt{53} = 7.2801$

frosja888 [35]

Answer:

984

Step-by-step explanation:

DVDs comprises 31.3% of total. And we also know that there are 308 DVD. Thus, we can say:

308 is 31.3% of total

We can let total be x, thus we can write an equation as:

308 = 0.313x

Solving for x:

$308 = 0.313x\\x=\frac{308}{0.313}\\x=984.02$

We can round and say there are 984 total movies
