Do the ratios 8:10 and 5:4 form a proportion?
sukhopar [10]
No because 8 is to 5 and 10 is to 4, they aren’t connected. Or you can do 8/10= .8 and 5/4= 1.25, they are not the same

Matteo is following this recipe to mak
ololo11 [35]

Answer:

Below is the step by step explaination of the procedure

Step-by-step explanation:

So since he wants to make three cakes we will multiply the recipe by 3 to get the amount of ingredients this person will need.

6*3 = 18 ounces of butter

5*3 = 15 ounces of sugar

7*3 = 21 ounces of flour

3*3 = 9 eggs

2 * 3 = 6 teaspoons of baking powder.

Gwar [14]
Multiply both sides by 3 to cancel out the 3 in the denominator of the left side of the equal sign. You get:

x + 4 = 18

Now subtract 4 from both sides to get variables one side, constants on the other. 

x = 18 - 4
x = 14

Your answer is x = 14
