As said above if b = 5 and you have 7b that means you are doing 7x5 and then adding 10 so a simplified way of doing this is to plug in 5 for b and making your expression
10+7(5) = ?

From that you just do PEMDAS and you find your answer of 45.

Sphinxa [80]
Hey there! Let’s solve the question first.

(6^4)^-3= 4.593 or 4.6

The reason behind this, 6^4=1296^-3

And 1269^-3= 4.593 or 4.6

Hope this helps!

Plz HELP! WILL GIVE BRAINLIEST!<br><br>1. Consider the picture below. Find the measure of ∠CEA.
pashok25 [27]

Answer:

  103°

Step-by-step explanation:

The marked angles have the same measure, so ...

  14x+7 = 12x +17

  2x = 10 . . . . . subtract 12x+7

  x = 5 . . . . . . . divide by 2

  (14x +7)° = 77°

∠CEA is supplementary to the marked angles:

  ∠CEA = 180° -77°

  ∠CEA = 103°

Triangle G F E is cut by line segment H J. Line segment H J goes from side G E to F E. The length of G F is 4 x minus 4, the len
alexira [117]

Answer:

HJ = 8  JE = 4

Step-by-step explanation:

it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.

HJ= 1/2 (GF)

x + 3 = 1/2 (4x - 4)

x + 3 = 2x - 2

x = 5

^ Thus meaning the value of x is 5.

Now you just fill into your equations:

HJ = x + 3 = (5)  + 3 = 8

JE = x - 1 = (5) - 1 = 4

Therefore, HJ = 8; JE = 4.
