Answer:
A 40•d
Step-by-step explanation:
The product of 40 and the distance (d)
40•d
B is division
C is subtraction
D is addition
The product of two numbers is multiplication, so the answer must be A
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 = 27
Step-by-step explanation:
We can say that sum of all interior angles adds up to: 180°, therefore;
(3x - 17) + (2x - 5) + (x + 40) = 180°
=> now add like terms together:
=> 3x + 2x + x = 6x
=> -17 + (-5) + 40 = 18
Therefore;
6x + 18 = 180°
6x = 180 - 18
6x = 162
x = 162/6
<u>x = 27</u>
Hope this helps!
