Directions: Follow the instructions for the following inequalities.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 504 < 1512
2. 12 > 0
3. -2 = -2
4. -1 < 2
Step-by-step explanation:
Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.

This depends on your definition of close.
Rational numbers are numbers that can be written as p/q where p and q are integers and q is not 0. Examples include 22/7 or 1 or 0.5.
Irrational numbers are not rational. Example include pi or square root of 2.
Two rational numbers close to -8 could be -9 and -25/3. Two irrational numbers could be -e and [tex]-5\sqrt{2}[/tex].
Then the order goes -9,-25/3 (since it is -8.333...),[tex]-5\sqrt{2}[/tex] (root 2 is around 1.4 so it is near -7),-e(around -2.7)

Step-by-step explanation:
what is this (6x+4)+26=90 ?
Answer:
x=10
Step-by-step explanation:
(6x+4)+26=90
6x+4+26=90
6x+30-30=90-30
6x÷6=60÷6
x=10
Answer:
the answer is X=10
(6x+4)+26=90
6x +30=90
6x= 90÷30
6x=60
X = 60÷6
X= 10
77 PTS!! On the following composite figure, all angles are right angles. All short edges of the figure have a measure of 1.5 centimeters. All long edges have a measure of 3 centimeters. Find the area of the figure. Explain or show how you got your answer.
Answer:Answer:
27 cm²
Step-by-step explanation:
There are many ways the figure can be decomposed into parts for which you know the area formula. The total area is the sum of the parts.
__
decomposition
We recognize that each of the tabs is twice as long as wide, so is half a square. The 4 tabs together make 2 squares that are 3×3 cm. Of course, what remains after removing the tabs is a 3×3 cm square in the middle of the figure.
sum of parts
Then the total area is that of 3 squares measuring 3 cm × 3 cm:
A = s² = (3 cm)² = 9 cm² . . . . . area of one square
total area = 3A = 3(9 cm²) = 27 cm²
The area of the figure is 27 cm².

Alternate solution
The figure can also be considered to be a 6 cm × 6 cm square with four 1.5 cm × 1.5 cm squares removed from its corners. Then the area is ...
(6 cm)² -4(1.5 cm)² = (36 -4(2.25)) cm² = 27 cm²

OK LAST QUESTION...maybe...YEAH LAST QUESTION!!!
THANK YOU GUYS SO MUCH!!! <333333
The value of x is:
↬ 73Solution:
If two angles are supplementary, that means that the sum of their measures is 180°.
We're given 2 angles:
[tex]\sf{\angle m}[/tex][tex]\sf{\angle n}[/tex]And since they're supplementary, the following holds true:
[tex]\sf{\angle m + \angle n = 180}[/tex]
Next, we know that [tex]\sf{\angle m=34}[/tex], so we plug that in
[tex]\sf{34+\angle n = 180}[/tex]
Then, ∠n = 2x:
[tex]\sf{34+2x=180}[/tex]
Which is the same as
[tex]\sf{2x+34=180}[/tex]
Subtract 34 from each side
[tex]\sf{2x=146}[/tex]
Divide each side by 2
[tex]\sf{x=73}[/tex]
Hence, x = 73find area of the shaded region use 3.14 for pi
Answer: The area of the shaded region is 50.24 square centimeter
Step-by-step explanation:
The given parameters are: -- the diameter of the big circle -- the diameter of the small circleStart by calculating the area of the big circle, using:So, we have:Next, calculate the area of the small circle, using:So, we have:The difference between the areas is the area of the shaded region.So, we have:Substitute known values Hence, the area of the shaded region is 50.24 square centimeter
