Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 9² = 16²
x² + 81 = 256 ( subtract 81 from both sides )
x² = 175 ( take the square root of both sides )
x = 
= 5 ≈ 13.23 units ( to 2 dec. places )
Answer:7x-4= 3
Step-by-step explanation:
4 less than the product of 7 and a number is equal to 3.
The answer is 7x-4= 3 beacuse:
(a. whenever you have something less than , the first number in the sentence (in this cacse 4) goes after the second number (in this case 7) with a subtraction sign in the middle. (imagine this equation looking like 7-4 <u>for now)</u>.Thats a little trick i use whenever i have to write "something less than something"
(b. okay so now we know it has to be 7 times somethig -4=3, but now we just need to write the "product of 7 and a number" in proper form. in other words, whenever you get somethig times a number, it is always going to be that number with an x right next to it. so thats why i made it 7x.
(c. "equals 3" is easy because you just turn it into an "=3".
(d. Now put it together. "4 less than the product of 7 and a number is equal to 3." becomes 7x-4=3.
Hope this helps :)) Also brainliest would be appreciated, worked pretty hard on this ! :D
Answer:
Answer will be 6561 x ∧ 8
Step-by-step explanation:
Given that:
(3x) ∧ 12 / (3x) ∧ 4
3∧(12-4) * x ∧ (12-4)
3∧8 * x ∧ 8
6561 x∧8
