How do you solve for x?

x = 7

Step-by-step explanation:

Because of the Alternate Exterior Angles Theorem, (7x + 1) = 50. (It states that if two lines are parallel, the resulting alternate exterior angles will be congruent)

Now, just solve for x from that equation:

1. 7x + 1 = 50

2. 7x = 49

3. x = 7

Step 1 is the given equation found by using the alternate exterior angles theorem

In Step 2, 1 was subtracted from both sides of the equation

In Step 3, both sides of the equation were divided by 7

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
