Answer:

Iris weighs 55 pounds, Ivan weighs 65 pounds.

Step-by-step explanation:

Divide 120 by 2: 60

Then make the 10 pound difference by adding and subtracting 5 to 60 for each answer: 55 and 65.

Iris = 55 pounds

Ivan = 65 pounds

Let x be Iris and y be Ivan.

x+ y = 120

y-10+ y = 120

2y - 10 = 120

2y = 120 + 10

2y = 130

y = 130/2

y = 65 pounds

x = y-10

= 65-10

x = 55 pounds

Cameroon was paid $173.70 for working 18 hours. how much money does he make per hour?
PilotLPTM [1.2K]
Since you are looking for the dollar per hour, can just set the equation up as dollar divided by hour (dollar/hour). You take how much was made ($173.70) and divide it by the hours worked (18 hours).

$173.70/18 = x (x representing how much he makes an hour).

$173.70/18 = $9.65.

Cameroon makes $9.65 an hour.

x = 8

Step-by-step explanation:

Each side of the triangle on the left is divided by 3 to get the side of the triangle on the right.
