Answer:
<h3> the first number is 5</h3><h3> the first second is 6</h3><h3> the first number is 1</h3>
Step-by-step explanation:
x - first number
2x - twice the first number
twice the first number exceeds the second number by 4 so:
2x-4 -the second number
y - the third number
the second number is equal to the sum of the first and third numbers:
2x-4 = x + y
x + y = 2x - 4
-x -x
y = x - 4 - the third number
the sum of three numbers:
x + 2x-4 + x-4 = 4x - 8
The sum of three numbers is 12 so:
4x - 8 = 12
+8 +8
4x = 20
÷4 ÷4
x = 5
2x-4 = 2•5 - 4 = 6
x-4 = 5 - 4 = 1
Check:
5+1 = 6
2•5 = 10, 10-4 = 6
Answer:
u = 24
Step-by-step explanation:
Simplify both sides of the equation.
1/3u+29=37
Subtract 29 from both sides.
1/3u+29−29=37−29
1/3u=8
Multiply both sides by 3.
3*(1/3u)=(3)*(8)
u=24

Answer:
- quotient: 2x^2 +3x +7
- remainder: 20
Step-by-step explanation:
See the attachment.
At each step, the value being subtracted from the dividend is the product of the quotient term and the divisor. The quotient term is found by dividing the highest-degree term of the dividend by the highest degree term of the divisor (x).
When the dividend has a degree that is less than the degree of the divisor, we call that value (20) the remainder.
