The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angle

Oduvanchick [21]

Answer:

The two angles are 25.5 and 114.5

Step-by-step explanation:

x = measure of one angle

5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}

x + 5x - 13 = 140 {sum of the two angles is 140}

6x - 13 = 140 {combined like terms}

6x = 153 {added 13 to each side}

x = 25.5 {divided each side by 6}

5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}

Solve for k 4.5+1.5k=18−3k

sertanlavr [38]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{k = 3}}}}}$

Step-by-step explanation:

$\sf{4.5 + 1.5k = 18 - 3k}$

Move 3k to left hand side and change it's sign

Similarly, move 4.5 to right hand side and change it's sign

$\longrightarrow{ \sf{1.5k + 3k = 18 - 4.5}}$

Collect like terms

$\longrightarrow{ \sf{4.5k = 18 - 4.5}}$

Subtract 4.5 from 18

$\longrightarrow{ \sf{4.5k = 13.5}}$

Divide both sides by 4.5

$\longrightarrow{ \sf{ \frac{4.5k}{4.5} = \frac{13.5}{4.5} }}$

Calculate

$\longrightarrow{ \sf{k = 3}}$

Hope I helped!

Best regards! :D

What are the intercepts of the line?

Schach [20]

To solve your X int you substitute 0 for y.

X int-
-5x+9(0)=-18
-5x=-18
X= 18/5 and the coordínate is (18/5,0)

Then to solve for y int you substitute 0 for x.

-5(0)+9y=-18
9y=-18
Y= -2 and the coordinate is (0,-2)
