Monica [59]

Answer:

55.27 miles

Step-by-step explanation:

Hello, I think I can help you with this

you can easily solve this by using a simple rule of three

Step one

If 1 mile is approximately 1.61 kilometers,it is

1 miles ⇔ 1.61 Kilometers

the, how many miles(x) are 89 km?

x ⇔ 89 kilometers

the relation is

$\frac{1\ mile}{1.61\ km}=\frac{x}{89\ km} \\$

Step two

solve for x( isolating x)

$\frac{1\ mile}{1.61\ km}=\frac{x}{89\ km} \\\frac{1\ mile*89\ km}{1.61\ km}=x\\x=55.27\ miles$

55.27 miles

Have a good day

2+3=8, 3+7=27, 4+5=32, 5+8=60, 6+7=72, 7+8=?? Solve it

alisha [4.7K]

Answer:

2+3=2*[3+(2-1)]=8

3+7=3*[7+(3-1)]=27

4+5=4*[5+(4-1)]=32

5+8=5*[8+(5-1)]=60

6+7=6*[7+(6-1)]=72

therefore

7+8=7*[8+(7-1)]=98

x+y=x[y+(x-1)]=x^2+xy-x
