To solve an equation with a rational (fraction) coefficient you need to multiply both sides of the equation by the reciprocal (invert the fraction - flip it).
The reciprocal of 1/6 is 6/1 or 6
The product of reciprocals equals 1
1x = 24
x = 24
The surface area of the triangle is 1/2 * 6*8 so it is 24 sq units
The whole thing is 24* 7.5 so it is 180 sq units
Was there a chart with this?
Answer:
Step-by-step explanation:
you want to divide 36 by 8 because you have 36 people and the recipie only makes it for 8.
You know that you will need to make the recipe 4.5 times.
So, multiply all the ingredient numbers by 4.5
2 x 4.5 = 9 quarts of water
3 x 4.5 = 13.5 sticks of cinnamon
1 x 4.5 = 4.5 tablespoons of coffee
