Determine m∠U if m∠R = 9x - 10 and m∠U = 3x + 4.

german

Answer:

50.5 degrees

Step-by-step explanation:

Since this is a parallelogram then...

Angle U + Angle R = 180

3x+4+9x-10=180

Combine like terms

12x-6=180

Add 6 to both sides

12x=186

Divide both sides by 12

x=15.5

Now we plug 15.5 in for x to find Angle U

3(15.5)4=46.5+4=50.5

Angle U = 50.5 degrees

NikAS [45]

Step-by-step explanation:

❉ $\underline{ \underline{ \sf{Given}}} :$

x = 5

❉ $\underline{ \underline{ \sf{To \: find}}} :$

value of 7 ( 4 + x )

Plug the value of x and simplify :

⟿ $\sf{7(4 + 5)}$

Add the numbers : 4 and 5

⟿ $\sf{7 \times 9}$

Multiply 7 by 9

⟿ $\boxed{ \sf{63}}$

Elena and Jada are 25 miles apart when they start moving toward each other. Elena runs at a constant speed of 6 mph and Jada wal

Setler [38]

<u>Answer:</u>

The Time taken by Elena and Jade to meet up is 2.5 hours

<u>Explanation:</u>

Given,

Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph

Also, Distance can be calculated by the formula

$Distance = Speed * Time$

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values

Here it will be: $6 + 4$ = 10mph

Distance apart is given as 25 miles. Substituting the values,

$Distance = Speed * Time$

25 = $10 * time$

Time = 25/10

Time = 2.5 hour

Hence, It will take 2.5 hours to meet up.

1. Find the slope and the y-intercept

Dvinal [7]

Answer:

c) slope: -7 ; y-intercept: 2

Step-by-step explanation:

Note the slope intercept form:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

Note in this case:

y = (-7)x + 2

y = y

m = -7

x = x

b = 2

c) slope: -7 ; y-intercept: 2 is your answer.
