We can use trial or error method here...
If we take 4 table, 4*5 = 20 and 4*7 = 28. 20+28 = 48.
20 : 28 = 5 : 7
So, there are 20 boys and 28 girls in a school play and there are 8 girls more than boys.
If you look over tables and try it out, only 4 table works for the given ratio.
..36, 49, 64, 81...- answer.
1 (+3); 4 (+5); 9 (+7); 16 (+9); 25 (+11); 36 (+13); 49 (+15); 64 (+17); .......
Answer:
x = 5
Step-by-step explanation:
It is given that the angle below is a right angle, meaning that it is 90 degrees.
So, 8x and 50 must both add up to 90 degrees.
Let's make an equation that we can solve using this information.
8x + 50 = 90
8x = 40
x = 5
