Step-by-step explanation:
solving 2 step inequalities give three solutions for each inequality -3(1-z)<9
Answer:
-3, -2 and -1
Step-by-step explanation:
Given the inequality -3(1-z)<9
Expand
-3(1)-3z <9
-3-3z <9
Add 3 to both sides
-3-3z+3<9+3
-3z<12
Divide both sides by -3
-3z/-3 >12/-3
z > -4
The required solutions are values greater than -4 and they are -3, -2 and -1
NOTE: Angles not necessarily drawn to size . what is x?
Answer: 45
Step-by-step explanation: 160-115= 45 you do this because the angles are across the vertex from each other.
Answer:
X=45
Step-by-step explanation:
Method 1 ( the long one)
So AED and CEB are vertical angles, that means that the are the same and have the same value.
So 115 plus x equal 160.
115 + x = 160
from there we just have to subtract 115 from both sides to get x by itself.
115 + x = 160
-115 -115
_________________
x=45
Method 2 (short one
If you know that those are vertical angles, then just subtract 115 from 160 and there you go. You get 45.

Given center C and a point P on a circle, find its equation. C(-2, 7) and P(1, 11)
A. (x - 1)2 + (y - 11)2 = 5
B. (x + 2)2 + (y - 7)2 = 5
C. (x - 1)2 + (y - 11)2 = 25
D. (x + 2)2 + (y - 7)2 = 25
The equation of a circle with center at [tex]C(-2, 7)[/tex] and Point [tex]P(1, 11)[/tex] will be [tex](x+2)^2+(y-7)^2=25[/tex] .
What is equation of a circle ?
Equation of a circle is written in the form [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius.
We have,
Center at [tex]C(-2, 7)[/tex]
i.e. [tex]h=-2[/tex], [tex]k=7[/tex],
And
Point [tex]P(1, 11)[/tex]
i.e. [tex]x=1[/tex], [tex]y=11[/tex]
Now,
To determine Radius of the circle;
[tex]r^2=(x-h)^2+(y-k)^2[/tex]
[tex]r^2=(1-(-2))^2+(11-7)^2[/tex]
[tex]r=\sqrt{3^2+4^2} =\sqrt{25}[/tex]
[tex]r=5[/tex]
So, radius of the circle is [tex]5[/tex] .
Now,
Equation of a circle ;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
[tex](x-(-2))^2+(y-7)^2=5^2[/tex]
[tex](x+2)^2+(y-7)^2=25[/tex]
So, the Equation of a circle is [tex](x+2)^2+(y-7)^2=25[/tex] .
Hence, we can say that the equation of a circle with center at [tex]C(-2, 7)[/tex] and Point [tex]P(1, 11)[/tex] is [tex](x+2)^2+(y-7)^2=25[/tex] .

Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. What does the ratio 5 : 13 represent in this situation? Use a model to show your work. Explain your reasoning.
Answer:
m
Step-by-step explanation:
The ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias in Myra's flower bed.
A ratio shows us the number of times a number contains another number.
Given that Myra’s flower bed has three types of flowers. There are 7 lilies, 5 tulips, and 6 zinnias. Therefore, the ratio of number of Lilies to the number of tulips and zinnias are,
Ratio = Number of Lilies : Number of tulips and zinnias
Ratio = 5 : (7+6)
Ratio = 5 : 13
Hence, the ratio 5 : 13 in this situation represents number of Lilies to the number of tulips and zinnias.

Answer:
Step-by-step explanation:
Analyze what each part of the inequality means mathematically.x is the solution of the problem, the quantity you are looking for.6x means that, for a reason given in the problem, the quantity you are looking for is multiplied by 6.− 18 means that, for a reason given in the problem, 18 is subtracted from 6x.≤ 18 means that after multiplying the solution x by 6 and subtracting 18 from it, the result is at most 18.Think of some different situations in which a quantity x might be multiplied by 6.You plant 6 seeds from x different seed packets, and you want to know from how many different seed packets you plants seeds.Build on the situation and adjust it to create a verbal description that takes all of the information of the inequality into account.Elrich planted 6 seeds from each of x different seed packets in his garden. To plant these seeds, he had to remove 18 plants that were already in the garden. Including the plants he removed and the seeds he planted, he expected to have at most 18 plants in the garden. From how many different seed packets did Elrich recently plant seeds?

HELP ME PLEASE !! Last year, Eric biked n miles. This year, he biked 457 miles. Using n , write an expression for the total number of miles he biked.
====================================================
Explanation:
The variable n is a placeholder for a number. Specifically some positive number. Let's say that n = 50. This means Eric biked 50 miles last year.
That would mean in total he biked 50+457 = 507 miles overall over the two years.
Since we don't know what n is, we don't replace it with 50. So we just keep n as it is. We would keep it as n+457
Once, or if, we find out the value of n, then we can replace that letter with that number.
