1/5x = 2/5
x = 2/5 * 5/1 (5/1 is the inverse of 1/5)
x = 2
Answer:
2 1/3 cups of flour for every dozen muffins
Step-by-step explanation:
1 1/2 dozen muffins equals 3 1/2 cups of flour which is also the same as 7/2 cups of flour. I know that (3) 1/2 dozen equals 1 1/2 dozen so I divided 7/2 by 3 which is 1 1/6 to get how much flour for 1/2 dozen then multiplied it by 2 to get how much flour in a dozen = 2 2/6 which simplified is 2 1/3.
Answer:
X=-5
Step-by-step explanation:
√4x+8=x+3
Simplifies to:
2x+8=x+3
Let's solve your equation step-by-step.
2x+8=x+3
Step 1: Subtract x from both sides.
2x+8−x=x+3−x
x+8=3
Step 2: Subtract 8 from both sides.
x+8−8=3−8
x=−5
Answer:
