Answer:

(3x - 5°) = 52°

Step-by-step explanation:

Formula we use,

→ A + B + C + D + E = 540°

Then the value of x will be,

→ A + B + C + D + E = 540°

→ (6x + 25°) + (5x + 10°) + (3x - 5°) + (5x + 10°) + (6x + 25°) = 540°

→ (6x + 5x + 3x + 5x + 6x) + (25° + 10° - 5° + 10° + 25°) = 540°

→ 25x + 65° = 540°

→ 25x = 540° - 65°

→ 25x = 475°

→ x = 475/25

→ [ x = 19° ]

The value of angle (3x - 5°) will be,

→ (3x - 5°)

→ (3 × 19) - 5°

→ 57° - 5°

→ [ 52° ]

Hence, value of angle (3x - 5°) is 52°.

My has 3 times more books that grant , and grant has 6 f
Klio2033 [76]

I’m not sure what happened while you were writing this, but if I’m reading it right, “My” has 18 books. If “My” has 3 times as many as 6, that also means 3 times 6, which is 18.

Help!! this is kinda urgent​
Elenna [48]

Answer

In decimal form it is 1.25 and in fraction form it 1/4

Step-by-step explanation:

There might be and there are other ways but the way I did it is I  converted the fractions to decimals. 1 3/4= 1.75, 1 1/2= 1.5, and 4 1/2 equals 4.5. So I added the time he practiced on Monday and Tuesday and subtracted it from the final hour of the whole entire week and the answer is 1.25 or 1/4
