Answer:
x=3
Step-by-step explanation:
2x/3−x/10=17/10
Multiply each side by 30 to get rid of the fractions
30( 2x/3−x/10)=(17/10)*30
Distribute
20x -3x = 51
Combine like terms
17x = 51
Divide by 17
17x/17 = 51/17
x=3
Answer: The total width of iPads is 61.2 inches.
Step-by-step explanation:
Since we have given that
The mean width of 12 iPads = 5.1 inches
So, the Value of 12 iPads is given by

Similarly,
The mean width of 8 kindles =4.8 inches
So, the Value of 8 kindles is given by

We only need total width of the iPads which is 61.2 inches .
Hence, the total width of iPads is 61.2 inches.
BBBB? I had to have at least 20 characters...
Well, since you have the value of b, the first thing you want to do is substitute that value in for b.
5a - 10(3) = 45
10*3 = 30
5a - 30 = 45
Now, to get the variable by itself (a) you have to + 30 because you have to reverse the subtraction.
5a = 75
Now, you divide by 5 to finish getting a by itself.
a = 15
Hope this helps!

B= 0, -2
C= -2, -1
Step-by-step explanation:
originally the coordinates are x, y but if it is reflect over the line y = - x which will now turn your coordinates to (-y, -x)
