The value of the expression would be 16.25 or 16 and 1/4, because when you multiply something by 1/2, you’re basically dividing it by 2, and when you put parentheses next to a number (for example 2(4) ), it means that you’re multiplying it, and when more than one values are in the parentheses, they all get multiplied, basically distributive property.
Answer:
x=2
Step-by-step explanation:
x + 4 = 3(3x - 4)
Distribute
x+4 = 9x -12
Subtract x from each side
x+4 -x = 9x-x-12
4 = 8x-12
Add 12 to each side
4+12 = 8x-12+12
16 = 8x
Divide by 8
16/8 = 8x/8
2 =x
Answer:
x < 1
Step-by-step explanation:
we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side
So
Multiply both sides by 2
2A = h(x+y)
Divide both sides by h
2A/h = x+y
Subtract y from both sides
or
First of all , you need to find the area of both walls and then add them together to get the amount of square feet in one wall. You also have to multiply the answer by 2 to get the square feet that need to be painted.
19*15=135 --> 135*2= 270
8*10= 80 ---> 80*2= 160
once you have done this you add 160+270, and you get your which is yes, because there is only 430 squared feet that need to be painted.
