- 8x + 4 ≤ 36
Subtract 4 from both sides.
-8x ≤ 32
Divide both sides by -8.        When dividing by a negative number change the
 x ≥  - 4                                   inequality sign.

Math help please help me with this page
White raven [17]
Please, post just one problem at a time, or (if you post more than one), indicate which one you want to focus on first.  Even more important, please do whatever you can to get started on each problem; I'm sure you know at least some basics.

What does "intersecting" mean?  Look it up if you're not sure.

Then what would "two intersecting lines" look like?  Draw the graph, or at least explain in words what the graph would look like.

PLEASE HELP NOW!!!<br> QRST is a square. Use the properties of a square to find the value of x.
Annette [7]

Answer:

x = 6

Step-by-step explanation:

QRST is a square.

QR = RS (sides of a square are equal)

7x - 10 = 5x + 2

7x - 5x = 10 + 2

2x = 12

x = 12/2

x = 6

Point m lies between points l and n on line segment l n . the space between l and m is 10 x 8. the space between m and n is 5 x
Ivenika [448]

The length of line segment l n on which point m lines in between is 64 units. Option 4 is the correct option.

<h3>What is the length of line segment?</h3>

Length of a line segment is the distance of both the ends of it.

Point m lies between points l and n on line segment l n .

  • The space between l and m is 10x 8.
  • The space between m and n is 5x -4.

The value of line segment LN is,

LN = 12x +16

The sum of LM and LN is equal to the line segment LN. Thus,

LM+MN=LN\\10x +8+(5x-4)=12x+ 16\\10x +8+5x-4=12x+ 16\\10x+5x-12x=16 -8+4\\3x=12\\x=\dfrac{12}{3}\\x=4

Put this value of x in the equation of line segment LN,

LN = 12(4) +16\\LN=48+16\\LN=64\rm\; units

Thus, the length of line segment l n on which point m lines in between is 64 units. Option 4 is the correct option.

Walter is practicing his high jumps for the track team. His first jump measured 5 feet, 9 inches. His second jump measured 3 fee
tia_tia [17]

Answer: 1.834 ft

Step-by-step explanation:

Given

Walter's first Jump is 5 ft, 9 in.

His second Jump is 3 ft, 11 in.

We know,

1\ ft=12\ in

Converting inches to feet

First Jump in feet

\Rightarrow 5\ ft+\frac{9}{12}\ ft=5.75\ ft

Second jump

\Rightarrow 3\ ft+\frac{11}{12}\ ft=3.916\ ft

The difference in the measurement of two Jumps is

\Rightarrow 5.75-3.916=1.834\ ft

So, Walter first Jump is 1.834 ft higher than the second Jump
