Solve for k 5/8(3k+1)-1/4(7k+2)=1

lesya [120]

Answer:

<h2>k = 7</h2>

Step-by-step explanation:

$\dfrac{5}{8}(3k+1)-\dfrac{1}{4}(7k+2)=1\qquad\text{multiply both sides by 8}\\\\8\!\!\!\!\diagup^1\cdot\dfrac{5}{8\!\!\!\!\diagup_1}(3k+1)-8\!\!\!\!\diagup^2\cdot\dfrac{1}{4\!\!\!\!\diagup_1}(7k+2)=8\cdot1\\\\5(3k+1)-2(7k+2)=8\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\(5)(3k)+(5)(1)+(-2)(7k)+(-2)(2)=8\\\\15k+5-14k-4=8\qquad\text{combine like terms}\\\\(15k-14k)+(5-4)=8\\\\k+1=8\qquad\text{subtract 1 from both sides}\\\\k=7$

PLEASE HELP ME WITH THESE FOUR QUESTIONS TYSMMM!!! THANK YOU

Dima020 [189]

Answer:

$107^\circ, 133^\circ, 20^\circ, \text{and}, 23^\circ$

Step-by-step explanation:

9. For the lines 'm' and 'n' to be parallel the sum of interior angles should be 180 degrees that is:

$x+73^\circ=180^\circ$

$x=107^\circ$

10. For the lines 'm' and 'n' to be parallel the alternate exterior angles should be equal that is:

$147^\circ=x+14^\circ$

$x=147^\circ-14^\circ$

$x=133^\circ$

11. For the lines 'm' and 'n' to be parallel alternate angles should be equal that is:

$180^\circ-3x=2x+20^\circ$

Solving for 'x' we get:

$180^\circ-20^\circ=3x+2x$

$5x=160^\circ$

$x=32^\circ$

12. For the lines 'm' and 'n' to be parallel corresponding angles should be equal that is:

$(7x-11)^\circ=(4x+58)^\circ$

$7x-4x=58^\circ+11^\circ$

$3x=69^\circ$

$x=\frac{69}{3}=23^\circ$
