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
30 people are on each team
divide the number of students by the number of teams the principal organizes.
When a quantity y changes at a constant rate with the respect to a quantity x you can use a equation to model the relationship.
sorry if this doesn’t make sense I tried my best!
Answer:
It's hard to read, but I think it is B
Step-by-step explanation:
Apples Bananas Lemons Oranges Pears
6 2 10 8 4
Apples 6/30 = 1/5
Bananas 2/30=1/15
Lemons 10/30 = 1/3
Oranges 8/30 = 4/15
Pears 4/30 = 2/15
