angle abc and ghk are equal by given. you set them equal and solve like this.

6x+2=5x-27+3x+1 combine like terms

6x+2=8x-26 subtract 6x from both sides

2=2x-26 add 26 to both sides

28=2x divide both sides by 2

x=14

measure of abc would be 6x+2 or 6(14)+2 or 86 degrees

pen costs twice as much as a pencil. The total cost of 1 1 pen and 1 1 pencil is $2.10 $ 2 . 10 . If p represents the cost of 1

dybincka [34]

Answer : The equation could you use to find p is, $2p+p=2.10$

Step-by-step explanation :

Let the cost of 1 pen be, 'x'

and the cost of 1 pencil is, 'p'

As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:

$x+p=2.10$ ............(1)

And we have also given that the pen costs twice as much as a pencil. The equation will be:

$x=2p$ ............(2)

Now put the equation 2 in equation 1, we get:

$x+p=2.10$

$2p+p=2.10$

Thus, the equation could you use to find p is, $2p+p=2.10$

What’s the answer to: 7=a/2+4

Likurg_2 [28]

7 = a/2 + 4

first subtract 4 from both sides

7 (-4) = a/2 +4 (-4)
3 = a/2

Then isolate a by multiplying 2 to both sides

3(2) = a/2 x 2
6 = a

a = 6

hope this helps

The probability would be 0.56.

Conditional probability is given as:

P(A and B) = P(A) * P(B|A). In this case, we have

P(E and F) = P(E) * P(E|F) = 0.7(0.8) = 0.56.
