Could x = - 5 be a solution to the inequality
-6 < 3x + 9 < 21?
Answers
Step-by-step explanation:
[tex]3x + 9 = 3( - 5) + 9 \\ = - 15 + 9 \\ = - 6[/tex]
3x+9 is equals to -6 , not more than based on the inequality, but it is lesser than 21.
However, the solution must fulfil both criteria to be a solution to the inequality. Therefore x = -5 is not a solution to the inequality.

3) 63
Step-by-step explanation:
1)
50% = 0.5
84(0.5) = 42
2)
25% = 0.25
84(0.25) = 21

Given the diagram below, what is mD?
Answers
Answer:
A
Step-by-step explanation:
Answer:
A. 72
Step-by-step explanation:
There are two ways to solve this problem. First of all, this quadrilateral is a trapezoid because the top two angles are congruent and there is one pair of parallel lines. One way to solve the problem is to remember all trapezoids have a measure of 360. So, mD=360-(108+108+72); this equals 72. Additionally, in a trapezoid, the bottom two angles are always congruent; therefore, angle D must equal 72 degrees.

Answers

Answer:
C. 35.3 km
Step-by-step explanation:
From your knowledge of right triangles, you know that the hypotenuse is longer than the longest leg and shorter than the sum of the legs.
For this geometry, the distance of interest is longer than 32 km and shorter than 15+32 = 47 km. The only answer choice in the correct range is ...
35.3 km

6x + 52 = 100
now we solve

and then for zz it’s 360 - 200

divide by 2 so
80
SOOOO
x = 8
z = 80
sorry the explaining sucks ;-;
Answer:
X=8
z=80
Step-by-step explanation:
Okay to find X you gotta find the other angle.
The other angle is 100 which is also vertical To (6x+52)
Vertical angles are equal or congruent so you cna make an eqaution to equal it
6x+52=100
Solve it like a normal equation
x=8
To find Z you gotta realize that 4 angles equal 360 degrees.
We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z
Now If you add em all up you should get 360
2z+100+100=360
2z+200=360
Solve from here
z=80

Whats the area of number 10 ? Help please, help me do it and explain if you can! BTW THIS IS COMPOSITE SHAPES
Answers
Answer:
10. Area = 72 units²
Step-by-step explanation:
10. The shape in number 10 is a trapezoid.
Area of trapezoid = ½(a + b)*h
Where,
a = 6
b = 12
h = 8
Area = ½(6 + 12) * 8
Area = ½(18)8
Area = 72 units²
Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(2, - 6) * B * (5, - 6), C(5, - 2) and D(2, - 2) . What the perimeter of rectangle ABCD
Answers
Answer:
14 units.
Step-by-step explanation:
Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.
P = 2(l + w)
P = 2(3 + 4)
P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)
P = 14 units and 14 units.
You could also do addition.
P = 3 + 3 + 4 + 4
P = 6 + 8
P = 14 units

Answer:

Step-by-step explanation:
We want to isolate n to solve the inequality. To do that, you add 4 to both sides, so 4 + 4 = 8 on the left and n - 4 + 4 = n on the right. That leaves you with 8 ≤ n, or n ≥ 8.
