Answer:
question 9
92/11 or 8.36
Step-by-step explanation:
angle on straight line is 180
:. 10x+1 + 12x-5 = 180
collect like terms
10x+12x = 180+5-1
22x = 184
divide both sides by the coefficient of x
22x/22 = 180/22
:. x = 180/22(to d lowest form= 92/11)
or 8.36
Answer:
x = 10
Step-by-step explanation:
y = 2x + 1
21 = 2x + 1
21 - 1 = 2x
2x = 20
x = 10
Answer:
205/66
Step-by-step explanation:
3/4 + 7/18 = 41/36
11/12 . 2/5 = 11/30
41/36 : 11/30 = 205/66
You graph it by the y axis and that have a number 1 and you graph it straight sideway
