THAT THE TRIANGLE ACCORDING TO QUESTION AND I THINK SO OPTION A IS RIGHT 95%
Answer:
Total money = $30,00,000
Step-by-step explanation:
Given:
4/5 money spend on house
3/4 remaining money spend on luxury yacht
2/3 remaining money spend on trip to space
Remaining $50,000 to charity
Find:
Total money
Computation:
Assume Total money = x
So,
Spend on house = [4x/5]
Spend on luxury yacht = [x-4x/5]3/4 = 3x/20
Spend on trip to space = [x/5-3x/20]2/3 = x/30
Remaining money = x/20 - x/30 = x/60 = $50,000
So,
x/60 = $50,000
x = $300,000
Total money = $30,00,000
Answer:
x = -24
Step-by-step explanation:
3(x + 7) = 2x - 3
3 * x = 3x
3 * 7 = 21
3x + 21 = 2x - 3
-21 -21
3x = 2x -24
-2x -2x
x = -24
Answer:
Area = 27 cm²
Step-by-step explanation:
let L be the length of the rectangle
w the width
P the perimeter
A the area
<u>Formulas</u> :
P = 2×(L + w)
A = L × w
<u>We are Given</u> :
L = 3w
P = 2×(L + w)
⇔ 24 = 2×(3w + w)
⇔ 24 = 2×4w
⇔ 24 = 8w
⇔ w = 24/8 = 3
Then
L = 3w = 3×3 = 9
We obtain L = 9 and w = 3.
Then
A = L × w
= 9 × 3
= 27
