Fofino [41]
------------------------------------------------------------------------------------
Reduced (simplify) all factions if possible
------------------------------------------------------------------------------------

(1/4 cannot be reduced)
1/4 = 1/4

(divided by 2 for both numerator and denominator)
2/8 = 1/4

(divide by 3 for both numerator and denominator)
3/12 = 1/4

------------------------------------------------------------------------------------
Find combined fraction of the mural that has been painted.
------------------------------------------------------------------------------------
1/4 + 1/4 + 1/4 = 3/4

------------------------------------------------------------------------------------
Answer: 3/4 of the mural has been painted.

–2z − 7 need this done now
Debora [2.8K]

Answer:

the value of the z is -3.5

Step-by-step explanation:

According to the question, the following information is given

-2z - 7

Based on the above information

We assume that we have to determine the z value

so

-2z - 7 = 0

-2z = 7

z = 7 ÷ -2

= -3.5

Hence, the value of the z is -3.5

The same is to be considered and relevant too

Consider a circle with a diameter of 5 centimeters. Which equation shows how the relationship between the circumference and the
mrs_skeptik [129]

Answer:

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  \frac{C}{5} ⇒ answer C

Step-by-step explanation:

In any circle there is a constant ratio between the circumference of the circle and its diameter

This constant ratio is called π

∵ The formula of the circumference of a circle is C = π d,

    where d is the diameter of the circle

- Divide both sides by d

∴ \frac{C}{d} = π

- Switch the two sides

∴ π =  \frac{C}{d}

∵ The diameter of the circle is 5 centimeters

∴ π =  \frac{C}{5}

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  \frac{C}{5}

Iam stuck on this quiz and I need help!!
olya-2409 [2.1K]

Answer:

I think it is 3?

Step-by-step explanation:

3,  -2 ≤ 0

-5,  0 < -2 ≤ 5

3, -2 > 5

The second two lines do not hold true, as -2 is less than 0 and 5, not greater. The only that is true is the first one, but I am not sure that is how you do it.1
