Answer:
x=5
Step-by-step explanation:
3x+1= 4x+(-4)
-4×+1= -4x-1 combine like terms
-1x= -5 divided by -1
x= 5
You subtract 15.50 from 47.50
then you will get your answer it is 31
For this case we can make the following rule of three:
1 cup ----------------> 128 grams
x ----------------------> 192 grams
From here, we clear the value of x.
We have then:
x = (192/128) * (1)
x = 1.5
x = 1 1/2

Answer:
y = 15
Step-by-step explanation:
The triangles follow a scale factor. This scale factor can enlarge or make a triangle smaller, using this factor, like a ratio. We can do 22/10 to get this scale factor for the set, which is 2.2. Finally, divide 33 by 2.2 to get 15 for the missing side length y.
