Answer:

V=8.5

Step-by-step explanation:

o=oil. vinegar=v. furniture polish=f

O=3v

34= 3v + v

Using a system of guessing and checking if that number fits equation you can tell that 8 causes the equation to be unequal and also 9. You can learn V must be between 8 and 9 so 8.5 might fit the equation. 8.5=V

Two boats on opposite banks of a river start moving towards each other. They first pass each other 1400 meters from one bank. Th

Nesterboy [21]

S1 = speed of boat 1

t1 = time to do 1400 meters (boat 1)

S1*t1 = 1400

S2 = speed of boat 2

1400 + S2*t1 = X

t2 = time to do X + 600 (boat 2)

S1*t2 = X + 600

S2*t2 = 2X - 600

S1 = 1400/t1

S2 = (X-1400)/t1

T = t2/t1

1400*T = X + 600

X*T - 1400*T = 2X - 600

X = 3600 meters

River is 3600 meters wide

Amanda used 45 ounces of sugar to make 75 cupcakes. How many ounces of sugar will be used to make 255 cupcakes?

horrorfan [7]

Solution:

Ounces of Sugar used by Amanda to make 75 cupcakes = 45 Ounces

As, number of ounces of sugar is in Direct variation with number of cupcakes.

The meaning of direct variation is , the ratio of two variables in each case is same.

Here , Ratio of ounces of sugar, to number of cupcakes in each case will be same.

Let number of ounces of sugar which will be used to make 255 cupcakes be x ounces.

$\frac{45}{75}=\frac{x}{255}\\\\ \frac{3}{5}=\frac{x}{255}\\\\ x=\frac{255 \times 3}{5}\\\\ x=\frac{765}{5}\\\\ x=153$

So, Number of ounces of sugar which will be used to make 255 cupcakes = 153 ounces.
