Solve both equations for x:

2x+7 = 3

2x = -4

x = -2

Plug x into the equation which contains b:

b(-2) -10 = -2

-2b = 8

b = -4


Answer:

b = -4

x = -2

Which expressions represent the difference of exactly two expressions? Choose 3 answers: Choose 3 answers: (Choice
Ket [755]

Solution

To find out which expressions represent the difference of exactly

two expressions

a) 6(x+7) - 2

This can be simplified as

6x + 42 - 2

6x + 40

Clearly this does not represent difference of the two

expressions .


b) -2j

Clearly this represents a single expression , this does not represent

a difference of 2 expression .


c) 4f - 2g

Here we have 2 different expressions 4f and 2g

Difference of these 2 expressions are 4f - 2g

Hence , this option represent difference of exactly two

expression


d) 3xyz - 10

3xtz - 10 represnts a single expression

Here we have a single expression

Therefore it does not represent difference of exactly 2

expression .

Find m∠QPR..........
dexar [7]

Hey there! :)

Answer:

m∠QPR = 25°.

Step-by-step explanation:

Given:

m∠QPS = 40°

m∠RPS = 8x + 7°

m∠QPR = 9x + 16°

m∠QPS = m∠RPS + m∠QPR, therefore:

40° = 8x + 7° + 9x + 16°

Combine like terms:

40° = 17x + 23°

Subtract 23° from both sides:

17° = 17x°

Divide both sides by 17:

x = 1°

If m∠QPR = 9x + 16°, substitute in 1 for 'x':

9(1) + 16 = 9 + 16 = 25°.
