Step 1. Simplify 2/3(x - 7) to 2(x - 7)/3
2(x - 7)/3 = -2
Step 2. Multiply both sides by 3
2(x - 7) = -2 × 3
Step 3. Simplify 2 <span>× 3 to 6
2(x - 7) = -6
Step 4. Divide both sides by 2
x - 7 = -6/2
Step 5. Simplify 6/2 to 3
x - 7 = -3
Step 6. Add 7 to both sides 
x = -3 + 7
Step 7. Simplify -3 + 7 to 4
x = 4</span>

The product of the lengths of the parts of the chord is equal to the product of the lengths of the parts of the chord that divides it.

(7 cm)*(8 cm) = n*(4 cm)
(7*8 cm²)/(4 cm) = n
14 cm = n

n=\boxed{14}cm

A newspaper reports the following changes in the temperature of a city over 4 days:
Alexeev081 [22]

9514 1404 393

Answer:

  a) (2.64 -2/9 -0.35 +5/8)/4

  b) perform the sum, then the division, then round as needed

Step-by-step explanation:

a) The average of a number of items is their sum, divided by the number of items. Here, we want the average of 4 changes, so we compute it as the sum of the changes divided by 4.

  average change = (2.64 -2/9 -0.35 +5/8)/4

__

b) My calculator is capable of adding these numbers directly. For a result rounded to the nearest hundredth, it can be a good idea to represent the fractions using at least 3 decimal digits.

So, the steps would be ...

  • convert fractions to their decimal equivalents, using 3 decimal digits
  • add up the values
  • divide by 4
  • round to hundredths

Performing these steps, we get ...

  average change = (2.64 -0.222 -0.35 +0.625)/4 = 2.693/4

  average change ≈ 0.67 . . . degrees

The average daily temperature change of a city was 0.67 degrees.

In a factory, eggs are packaged in groups of six per box how many full boxes of eggs can the factory make with 937 eggs
GarryVolchara [31]

Answer:

156 boxes

Step-by-step explanation:

Simply divide the total amount of eggs (937) by the amounts which are packaged in the boxes (6)

937 / 6 = 156 \frac{1}{6}

So there are 156 full boxes and 1 egg left

Since you can't pack one egg, the answer is 156 boxes
