Answer:

110 degrees

Step-by-step explanation:

Supplementary angles add to 180 degrees.

We have two angles: one is unknown and the other is 70 degrees.

These 2 angles added together must equal 180.

x+70=180

Since we are trying to find x, the unknown angle, we have to get x by itself. Since 70 is being added to x, subtract 70 from both sides.

x+70-70=180-70

x=110

So, the other angle is 110 degrees

Answer:

x= 110

Step-by-step explanation:

Supplementary angles add to 180

Let x be the other angle

x +70 =180

Subtract 70 from each side

x+70-70=180-70

x = 110

#5 please help me solve this
igor_vitrenko [27]

Answer:

x intercept = -7/2

y intercept = 21/5

Step-by-step explanation:

-6x +5y = 21

To find the x intercept, set y=0 and solve for x

-6x +5(0) =21

-6x =21

Divide each side by -6

-6x/-6 = 21/-6

x = -21/6 = -7/2

To find the y intercept, set x=0 and solve for y

-6(0) +5y = 21

5y =21

Divide each side by 5

5y/5 =21/5

y = 21/5

algol [13]

Answer:

154,226 - (154,226 * 104) = x

Step-by-step explanation:

for this we have to think that the people who moved left, so they have to subtract

lake residents are 154,226

then we would have to subtract those who moved

that we calculate them as 14% of residents

0.14*154,226

then we finally have

154,226 - (154,226 * 104) = x

ser-zykov [4K]

Answer:

d. 6-19i

Step-by-step explanation:

(5-8i)+(1-11i)

<u>Step 1: Combine like terms within the parenthesis. There are </u><u>no </u><u>like terms within the parenthesis. So, drop the parenthesis and move on to the next step. </u>

(<em>Remember!! If you would have had a negative sign in front of either parenthesis, you would need to distribute out the negative sign).</em>

5 - 8i + 1 - 11i

<u>Step 2: Now add like terms.</u>

5 + 1 - 8i - 11i

6 - 19i

<em>You can't combine any more like terms, so this is your final answer.</em>

6 - 19i
