Answer:

n=2.5

Step-by-step explanation:

First, write an equation!

n+5n-6+2n+1=15

Now, combine like terms to make things easier.

8n-5=15

Cancel -5 from the left to isolate 5n as a variable.

8n-5+5=15+5

8n=20

Now divide both sides by 8.

8n/8=20/8

n=2.5

Help me find the answer <br>Tan 0 and Cot O

vesna_86 [32]

Answer:

Step-by-step explanation:

we can say the angle is also +45° going in the clock wise direction. so take Tan(45)= 1

Cot(45) = 1

b/c Tan(45) = Sin(45) /Cos(45) = ( $\sqrt{2}$ /2) / ( $\sqrt{2}$ /2) ofc that's just 1

b/c Cot(45) = Cos(45) / Sin(45) , which is the same as above 1

Nine times the difference of a number and five is the same as 5 increased by nine times the number plus five times the number .

horsena [70]

9(x-5)=5+(9x+5x)
9x-45=5+14x
9x-14x=45+5
-5x=50
X=50/-5
X=-10

Eva is making a pattern using these shapes can you arrange Evas shapes to make a symmetrical pattern

ratelena [41]

Answer:

pyramid, cone, sphere, cube

Step-by-step explanation:

A symmetrical pattern is one that is arranged in such a way that there is a progressive repetition of a pattern. Each pattern formed is the same with respect to each other.

Eva could form series symmetrical patterns with the shapes he has, which depends on the arrangement of the shapes to form desired pattern.

One simple pattern to be formed is;

pyramid, cone, sphere, cube

pyramid, cone, sphere, cube.

Thus, this would generate four symmetrical continuous patterns.

pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube : pyramid, cone, sphere, cube.
