Answer:

Step-by-step explanation:

∠DEC + ∠EDC + ∠ECD = 180  {angle sum property of triangle}

45 + 65 + ∠ECD = 180

110 +∠ECD = 180

∠ECD = 180 - 110

∠ECD = 70°

AB // CD and AE transversal

∠BAC = ∠ECD    {Corresponding angles are equal}

∠BAC = 70°

Answer:

70

Step-by-step explanation:

65 and 45 make up 110, and triangles are composed up 180°. The missing angle thatll make it add up to 180 is 70

Leanne has a gas card that has $150 on it. She spends $25 a week on gas. Write and recursive rule that represents the amount of
Tems11 [23]

In this question, it is given that

Leanne has a gas card that has $150 on it. She spends $25 a week on gas.

And we have to Write a recursive rule that represents the amount of money she has on her gas card after the first week  .

Recursive rule shows the relationship between previous value and the current value .

And here, the recursive rule is

a_{n} = a_{n-1}-25n

Where a(n-1) is the initial amount which is $150 . And a(n) is the amount after n week .

So for n=1, that is amount in the card after 1 week, we will get

a_{1} = a_{1-1} -25(1)
\\
a_{1} = a_{0} -25
\\
a_{1} = 150 -25
\\
a_{1} = $125

And that's the amount remaining in the card after 1 week .

kirza4 [7]

Answer:

2*(5x - 2) + 2*(3x+1) ; Perimeter = 62 centimeters

Step-by-step explanation:

2*(5x - 2) + 2*(3x+1) = 10x - 4 + 6x + 2

                                = 16x -2

If x = 4 , then Perimeter = 16*4 - 2 = 64 - 2 = 62 cm

Write the standard form of the equation that is parallel to y = -6x + 5 and goes through point (4, 4).
steposvetlana [31]

6x + y = 28.  The standard form of the equation that is parallel to y = -6x + 5 and goes through point (4, 4) is 6x + y = 28.

The equation is written in the slope-intercept form y = mx +b. So:

y = -6x + 5

The slope m = -6

Since the slopes of parallel lines are the same, we are looking for a slope line m = -6 and goes through point (4, 4).

With the slope-intercept form:

y = mx + b

Introducing the slope m = -6:

y = -6x + b

Introducing the point (4, 4):

4 = -6(4) + b

b = 4 + 6(4)

b= 24 + 4

b = 28

Then

y = -6x + 28

write the equation in standard form ax + by = c:

y = -6x + 28

6x + y = 28
