Answer:
1) 7(x/8) + 3/4 = -6
Step-by-step explanation:
The term (7/8)x can be written as 7(x/8).
_____
The associative and commutative properties of multiplication let you put the factors (7)(1/8)(x) in any order or grouping you like.
Here, instead of (7·1/8)·x, the question is offering the rewrite 7(1/8·x), a straightforward application of the associative property.
Answer:
B
Step-by-step explanation:
-x+2 > 1
-x+2+x > 1+x .... add x to both sides
2 > 1+x
x+1 < 2
x+1-1 < 2-1 ... subtract 1 from both sides
x < 1
After solving for x, we get x < 1
To graph this, plot an open circle at 1 on the number line and shade to the left of this value. The open circle indicates that 1 is not part of the solution set.
If your teacher requires you to graph this on an xy grid, then draw a vertical line through 1 on the x axis. Make this vertical line a dashed line. Then shade the entire region to the left of this dashed line. Any point in this shaded region will have an x coordinate that is less than 1. The dashed line acts like the open circle. The dashed line tells the reader "any point on this dashed line is not part of the solution set"
The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.
