Answer:
11.25
Step-by-step explanation:
34x - 136 = 9
(34x - 136) + 136 = 9 + 13634x = 14534x / 34 = 145 / 34x = 4.26470588235x = 4.26 (2 dp.)
Answer:
18.84
Step-by-step explanation:
Diameter = 12
Circumference of a circle = πD
= 3.14* 12
=37.68
Since its a semicircle, (that's half of a circle), divide the result by 2
= 37.68/2
= 18.84
Answer:
x-intercept=(5,0) y-intercept =(0,-6)
Step-by-step explanation:
to find the x-intercept you substitute 0 in for y so the you're left with 6x=30 and you divide it by 6 on both sides leaving you with x=5
To find the y- intercept you set x=0 which leaves you with -5y=30 and you divide both sides by -5 and you're left with y=-6
