5x4= 20
50x40=200
500x400=200000
Do you see the pattern? 5x4=20, which means that all you need to do is add the zeros. 50x40 has two zeros, which means it should equal 200.

Norma-Jean [14]
<h3>Answer:  angle Q = 75 degrees</h3>

Explanation:

The order of ABC and RPQ is important so we can match up the angles like so

  • angle A = angle R .... first letters
  • angle B = angle P .... second letters
  • angle C = angle Q ... third letters

Meaning that angle Q = 75 since angle C is this measure.

it cost $35 for one adult and two children to attend a show. It cost $60 for two adults and three children to attend the same sh
N76 [4]
Assume that,
adult = x
child = y

x+2y = 35 (1st equation)
2x+3y = 60 (2nd equation)
x = 35-2y (3rd equation)

Substitute 3 into 2 :

2(35-2y) + 3y =60
70-4y +3y = 60
y = 10

x+2y = 35
x+2(10) =35
x +20 =35
x = 15

One adult = $15

Products of equal value totaling $480 are sold to an audience of an unknown amount of people. the entrance fee is $10 per person
Sholpan [36]
Y = \frac{10x+480}{x}

This is because the total cost is 10x + 480 and then that needs to be divided by the amount of people.
