7(5a-4)-1=14-8a PLZ HELP
nignag [31]

Answer:

a=1

Step-by-step explanation:

7(5a-4)-1=14-8a

Distribute

35a - 28 -1 = 14 -8a

Combine like terms

35a -29 = 14 -8a

Add 8a to each side

35a+8a -29 = 14 -8a+8a

43a -29 = 14

Add 29 to each side

43a -29+29 = 14+29

43a = 43

Divide each side by 43

43a/43 = 43/43

a =1

Graph the linear inequality.<br> y&lt;2
Leya [2.2K]

Answer:

See attachment.

Step-by-step explanation:

We want to graph the linear inequality y<2

We  first of all graph  the corresponding linear equation y=2 with a dashed line because all points on this line do not satisfy the inequality.

We then shade below the line y=2, to show that all points below the boundary line are solution to the inequality y<2

Solve the equation <br> 3 1/4x=7 3/7
Artist 52 [7]

Answer:

\frac{217}{292}

Step-by-step explanation:

the given equation is

\frac{31}{4x} = \frac{73}{7}

cross multiplication gives

⇒ 31 * 7 = 4x * 73

⇒ 217 = 292 x

Dividing both sides by 292 will lead us to

⇒ \frac{217}{292} = \frac{292*x}{ 292}

cancelling out 292 on RHS

⇒ \frac{217}{292} = x

or

x=\frac{217}{292}
