If you multiply me by 7 add 1 and then divide by 4 you get 9 what number am I?

Put the number as x and translate the English into math;
(7x+1)/4=9
Then solve for x
8x+1=36
8x=35
x=4.375 or 4 3/8
Hope this helps.

Answer:

64 degrees

Step-by-step explanation:

Since the triangles are similar they have the same angle measures

$\frac{PR}{PQ} =\frac{SU}{ST}$ $\frac{21}{14}= \frac{6}{4}$

∠P = ∠S ∠R =∠U ∠Q=∠T

We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U

In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula

$A+B+C=180$

$46+70+C+180$

$116+C=180$

subtract 116 from both sides

$C=64$

Therefore ∠Q is equal to 64 degrees

Consider the sequence: 12, 17, 22, ... , ... , .... What is the 405th term of this sequence?

Mice21 [21]

A_n= a₁+(n-1)d

a₁ first term

n terms

d distance between each value

a_n= 12+(405-1)(5)=2032

Someone please help, i honestly don’t get how to find the angles

jeyben [28]

A.) the degrees inside the triangles are 50, 70, and 60. you know because 180-120=60
b.) you know that they are similar triangles because they have the same angle degrees.

im not sure if this is correct but i think it is :)
