A,a+1- two consecutive integers
a+a+1=47
2a+1=47 | subtract 1
2a=46 | divide by 2
a=23
Numbers are: 23,24
Charter schools: 46
Alternative schools: y
2y-10=46
2y=56
y=28
There are 28 alternative schools.
Answer:
Step-by-step explanation:
A straight line has 180 degrees.
43 + b + 50 = 180 Collect like terms
b + 93 = 180 Subtract 93
b = 180 - 93
b = 87
a + b + 75 = 180 All triangles have 180 degrees.
a + 87 + 75 = 180 Combine like terms
a + 162 = 180 Subtract 162 from both sides
a = 180 - 162
a = 18
