Add like terms:
5x+2x=7x
They are like terms because they have the same variable/combination of variables in front of them.

You know that 12x=60, and that x=5. Which property of equality would you use to conclude that 12•5=60?
alexandr402 [8]

ANSWER

The substitution property of equality.

EXPLANATION

We know that:

12x = 60

and that

x = 5

Since x=5 or 5=x , we can substitute x for 5 wherever we see x in the given equation.

When we do that, we obtain;

12 \bullet \: 5 = 60

This is what we refer to as the substitution property of equality.

What value of x would make the figure below a parallelogram? please show your work!​
lara31 [8.8K]

Answer:

x = 8

Step-by-step explanation:

Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.

16x-4 + 7x = 180, combine like terms

23x - 4 = 180, add 4 on both sides (isolate variable)

23x = 184, divide 23 on both sides

x = 8

The midpoint of AB is M(7. – 7). If the coordinates of A are (8,-6), what are the
IRISSAK [1]

Answer: B = (6,-8)

Step-by-step explanation:

first the midpoint formula is (\frac{x1+x2}{2},\frac{y1+y2}{2})

then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:

\frac{8+x}{2}=7

then solve it like an equation:

8+ x=14\\x=6

then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:

\frac{-6+y}{2} =-7

then solve it like an equation:

-6+y=-14\\y=-8

∴ the answer is x=6, y= -8

which is expressed as a point, B(6,-8)

Order from least to greatest ! 1.36,1.3,1.63 and this other 0.42,3.74,3.47.
frosja888 [35]
If you are putting them all in order from least to greatest it would be 0.42, 1.3, 1.36, 1.63, 3.47,3.74. But, if you are separating them the first set of three numbers you wrote would be ordered 1.3, 1.36, 1.63. Then, the second set would be ordered 0.42, 3.47, 3.74. Hope this helped!!!
