Answer:

x = 23

y = 110

Step-by-step explanation:

70 and  3x+1 are alternate exterior angles and that means they are equal

70 =3x+1

Subtract 1 from each side

69 = 3x

Divide by 3

69/3 =3x/3

23 =x

70 and y are same side exterior angles and that means they are supplementary ( add to 180)

70+y = 180

y = 180-70

y = 110

8х + 5у = -7<br> — 7х + бу = — 4
Levart [38]

Answer: x = -0.2651 and y = -0.9759

Step-by-step explanation:

Solution by substitution method

8x+5y= -7

-7x+6y= -4 = 7x-6y=4

Suppose,

8x+5y=-7→(1)

7x-6y=4→(2)

Taking equation (1), we have

8x+5y= -7

⇒8x= -5y -7

⇒x= -5y-7 / 8 →(3)

Putting x= -5y-7 / 8

in equation (2), we get 7x-6y=4

7(-5y-7/8)-6y=4

⇒-35y-49-48y=32

⇒-83y-49=32

⇒-83y=32+49

⇒-83y=81

⇒y= 81 / -83

⇒y= -0.9759→(4)

Now, Putting y= -0.9759 in equation (3), we get

x= -5y-7

x= -5(-0.9759)-7/8

⇒x= 4.8795-7/8

⇒x= -2.1205/8

⇒x= -0.2651

∴x= -0.2651 and y = -0.9759

Find the lateral area and the total area of the prism.
Tems11 [23]
We have that

1) the lateral area---------------->  L=P*h
P=(3+3+3)   h=6
L=(3+3+3)*6=54 in²

the answer part 1) is the lateral area is 54 in²

2) the total area=------------- > S=P*h+2B
2B=2*[3*3/2]     P*h=54

S=2*[3*3/2]+54=63 in²

the answer part 2) is the total area is 63 in²

If the sum of three consecutive terms of GP are k-4,k,k+5. Find k
labwork [276]

Answer:

k = 20

Step-by-step explanation:

t1 = a = k-4

a = k - 4

t2 = ar = k

(k-4)r = k - 4

r = k/(k-4)

t3 = ar^2 = k + 5

(k - 4)(k/k - 4)^2 = k+5

k^2/k-4 = k+5

k^2 = (k+5)(k-4)

k^2 = k^2 -4k +5k -20

0 = k -20

k =20
