Mr. Mohammed withdraw a sum of money from the bank. He gave 3/8 to his son and 1/4 to his daughter. If he had GHc 600 left, how
Lesechka [4]

Answer:

GHc 1600

Step-by-step explanation:

Step 1: Find the sum of the fractions of money he gave out

Fraction gave out = \frac{3}{8} + \frac{1}{4}

Step 2: Add the fractions together

Lowest common multiply (Lcm) of 8 and 4 = 8

= \frac{3+ 2}{8} \\= \frac{5}{8}

Step 3: Find the fraction left by subtracting fractions gave out from 1.

= 1 -  \frac{5}{8}\\\\= \frac{8 - 5}{8}  \\= \frac{3}{8}

Step 4:

Let the total money he withdraw from the bank = n

\frac{3n}{8} = 600\\3n = 4800\\n = \frac{4800}{3} \\n = GHc 1600

Each regular polygon has radil and apothem as shown. Find the measure of each numbered angle. ​
ruslelena [56]

Answer:

∠5 = 60°

 ∠6 = 30°

 ∠7 = 120°

Step-by-step explanation:

Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)

 ∠5 = 60°

 ∠6 = 30°

 ∠7 = 120°

What is the value of x?<br> A. 3<br> B. 9<br> C. 15<br> D. 30
ra1l [238]

Answer:

<em>C. 15</em>

Step-by-step explanation:

Assuming that these segments formed from each parallel line are proportional, x/5 = x-6/3.

Now cross multiply by multiplying each denominator by the opposite numerator, this is so the denominators or bottom numbers of each fraction will cancel.

x/5 = x–6/3 → (3)(x/5) = (3)(x–6/3) → 3x/5 = x–6 →

(5)(3x/5) = (5)(x–6) → 3x = 5(x–6) → 3x = 5x – 30.

The last step is to do the basic algebra to find x:

3x = 5x – 30

–5x –5x

[5x will cancel when you subtract both sides by 5x]

-2x = -30

(-1) (-1)

[2 negatives make a positive when -1 is multiplied by an expression with a negative coefficient]

2x = 30

÷2 ÷2

[divide both sides by 2 to simplify 2x to x]

x = 15

_____

You can also check that both sides are proportional because

5 → x

x = 15

5 → 15

3 → x – 6

x = 15

3 → 9

5 × <u>3</u> = 15

3 × <u>3</u> = 9

Solve and show your work please!x+7=2(3x-4)
Brrunno [24]

x + 7 = 2(3x - 4)         Remove the brackets

x + 7 = 2*3x - 4*2

x + 7 = 6x -  8            Subtract 7 from both sides.

x + 7 - 7 = 6x - 8 - 7  

x = 6x - 15                 Subtract 6x from both sides

x - 6x = - 15

-5x = - 15                   Divide by -5

-5x/-5 = -15/-5

x = 3
