155 degrees is the answer
Answer:
x=5.5
Step-by-step explanation:
Perimeter of ABCD=85
The perimeter is everything around the outside added together.
Form an equation:
3x+4+4x+6x-11+5x-7=85
Collect the like terms:
Like terms are terms that have the same powers and coefficient.
3x+4x+6x+5x=18x
4-11-7= -14
Put it back into an equation:
18x-14=85
Do inverse operations to find out what x is:
85+14=99
18x=99
99÷18=5.5 (we divide because, in algebra, when a number is next to a letter, it means times and as we want the inverse, you would have to divide)
x=5.5
Hope this helps :)
The answer is D.
y = x + 1 = 4 + 1 = 5
y = 1/2x + 3 = 1/2(4) + 3 = 2 + 3 =5
Which Problem Do You Need Help With?
Answer:
g = -32
Step-by-step explanation:
3 = g/-4 - 5
Multiply both sides of the equation by -4
-12 = g + 20
Swap sides so that the variable terms are on the left hand side
g + 20 = -12
Subtract 20 from both sides
g = -12 - 20
Subtract 20 from -12 to get -32
g = -32
