Multiply 4(-5) then add 6 and theres your X
Answer:
x = 3
Step-by-step explanation:
A parallelogram must have two pairs of parallel sides.
For this to be true, the alternate exterior angles of the diagonal must be congruent.
Hence the equation,
<u>10x + 4 = 13x - 5</u>
Simplify.
<u>9 = 3x</u>
<u>x = 3</u>

Answer:
Amount of material for chain link = 30 feet
Amount of material for rope = 50 feet
Step-by-step explanation:
Let the amount of chain link = X
The amount of rope be represented by Y
He bought a total of 80 feet of materials
Hence we have:
X + Y = 80 ....... Equation 1
Y = 80 - X
The chain-link cost two dollars per foot and the rope cost 1.50 per foot he spent a total of $135
X × $2 + Y × $1.50 = $135
2X + 1.5Y = 135 ......Equation 2
Substitute 80 - X for Y in Equation 2
2X + 1.5(80 - X) = 135
2X + 120 - 1.5X = 135
Collect like terms
2X - 1.5X = 135 - 120
0.5X = 15
X = 15/0.5
X = 30 feet
Substitute 30 feet for X in Equation 1
X + Y = 80 ....... Equation 1
30 + Y = 80
Y = 80 - 30
Y = 50 feet
Hence the amount of material he used for the chain link = 30 feet and the amount of material he used for the rope was = 50 feet
Answer: 4
<u>Step-by-step explanation:</u>
Melinda: y = 10x + 22
George: y = 13x + 10
13x + 10 = 10x + 22
<u>-10x </u> <u>-10x </u>
3x + 10 = 22
<u> -10 </u> <u> -10 </u>
3x = 12
<u>÷3 </u> <u> ÷3 </u>
x = 4
