What in proper????????????
Answer:
Let the numbers are
x, (x+2), (x-2) and (x+4)
Step-by-step explanation:
x + x +2 +x - 2+x+4 = 80
4x +4 = 80
4x =80-44x = 76
4x = 76
x = 76/4
x = 19x
x=19
(x+2) =19+2=21
(x-2) = 19-2=17
(x+4)=(19+4)=23
hope it helps

<u>Algebra I</u>
- Coordinates (x, y)
- Terms/Coefficients
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
2x - 3y = 25
5x + 3y = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine two equations: 7x = 35
- [Division Property of Equality] Divide 7 on both sides: x = 5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [1st Equation]: 2(5) - 3y = 25
- Multiply: 10 - 3y = 25
- [Subtraction Property of Equality] Subtract 10 on both sides: -3y = 15
- [Division Property of Equality] Divide -3 on both sides: y = -5
Answer:
i got 32 weeks??
Step-by-step explanation:
Explanation :
1) Write out the equation : X-10 + X-10 + X-10 = 63
2) combine like terms : 3x -30 = 63
3) Add 30 to both sides of the equation to cancel out 30 : 3x = 33
4) divide 3 from both sides of the equation : X = 11
Therefore, the value of x is 11
