Answer:
x = -1.2
Step-by-step explanation:
Th given equation is :
34(x + 4) = 14(x + 8)
Step (A) Distribute 34 on the left side of the equation such as :
34x + 34(4) = 14(x + 8)
34x + 136 = 14(x + 8)
Step (B) Distribute 14 on the right side of the equation such as :
34x + 136 = 14x + 14(8)
34x + 136 = 14x + 112
Step (C) Subtract 14x from each side of the equation.
34x + 136 - 14x = 14x + 112 -14x
20x + 136 = 112
Step (D) Subtract 136 from each side of the equation.
20x + 136 -136 = 112 -136
20x = -24
Step (E) Divide both side by 20
So, the value of x is (-1.2). Hence, steps (D) and (E) are incorrect.
Answer:
(2.5+3)

im not 100% sure though sorry
Answer:
see explanation
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w ( l is length and w is width )
given w = 63, then
2l + (2 × 63) = 324
2l + 126 = 324 ( subtract 126 from both sides )
2l = 198 ( divide both sides by 2 )
l = 99 m ← length of garden
-----------------------------------------------------------------
The area of a rectangle = lw ( l is length and w is width )
given l = 94, then
94w = 5828 ( divide both sides by 94 )
w = 62 cm ← width of window
Answer:
x=28
Step-by-step explanation:
Usually triangles equal 180 so if that's the case then you just add all of the angles together and set it equal to 180. So your equation should be 50+ 2x+ 3x-10= 180 and then solve that equation and you will end up with x=28. Hope this helped!!
Answer:
Step-by-step explanation:
-7x-2y=-13
x-2y=11
(subtract the first inequality from the second)
-7x-x = -8x
-2y-(-2y) = 0
-13-11= -24
-8x=-24
x=3
(now place the x value into the second inequality)
3-2y=11
-2y=11-3
-2y=8
y=-4
x=3
y=-4
