Choose the equation that is equivalent to this statement: 4 is 80% of x Math item stem image CLEAR CHECK 4x=0.8 4=0.8x 4⋅0.8=x x4=80100

4=0.8x

Step-by-step explanation:

4 = 80% of x

4 = 80/100 × x

4 = 0.8x

4 = 0.8x

Step-by-step explanation:

We need to translate these into mathematical equations:

- "4 is"; "is" always means "=", so we have "4 = ..."

- "80%" is just 80/100 because remember that % means "out of 100"

- "of x"; "of" always means "×", so we use multiplication: "* x"

Put this altogether:

4 = (80/100) * x

80/100 = 8/10 = 0.8

4 = 0.8x

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
