In order to create a line parallel to line “I”, rotate line “I” 180° about points “F”. This can be done clockwise or counterclockwise.
Answer:
19a.) 6x-1=4 --> 6x=5 --> x=5/6
b.) 4w+3=10 --> 4w=7 --> w=7/4
Evaluate when t= -2
20a.) 5t-3 --> 5(-2)-3= -10-3= -13
b) the sequence 5+t, 5+2t, 5+3t, 5+4t. = 3, 1, -1, -3
c.) 18- t² =18-(-2)^2= 18-4=14
20d) the sequence 2t- 3, 2t-5, 2t-7, 2t-9. = -7, -9, -11, -13
21.) Find the value of these expressions when p=2, q=3 and r=6
21 a)5q = 5(3)=15
b) p+q
= 2+3= 5
c) qr
= 3*6= 18
d) 2p+ 3q
= 2(2)+3(3)=4+9= 13
e) r² = 6^2=36
'is' in mathematics means equal
'of' in mathematics means multiplication
Translating 8 is 50% of what number into an equation, we get:
8 = 50% * x
50%, or 50 percent, is nothing but 50 over 100 or 50/100, which is the same as 1/2.
8 = 1/2 * x
Multiply 2 on both sides.
8 * 2 = 1/2 * 2 * x
16 = x
x = 16
8 is 50% of 16.
The answer to the question is number 8
