Answer:
A = <
B = >
C = >
D = >
Step-by-step explanation:
A
5/6 x 7 = 35/6 = 5.83
B
8/7 x 5 = 40/7 = 5.71
C
9/5 x 3 = 27/5 = 5.4
D
12/11 x 6 = 72/11 = 6.54
10x+2y=18
10x-7y=-18
Multiply the second one by -1
-10x+7y=18
Then add the two equations
10x+2y=18
+-10x+7y=18
----------------
9y=36
y=4
Plug that back into one of the equations above and solve for x
10x+2y=18
10x+2(4)=18
10x+8=18
10x=10
x=1
so your answer is x=1 and y=4 or (1,4)
Answer:
89-198345-19850 that's to the the tenth
Answer:
49
Step-by-step explanation:
1. Calculate the constant of proportionality
Q = k/p²
k = Qp² Multiplied each side by p²
= 36 × 7²
= 36 × 49
= 1764
2. Calculate the new value of Q
Q = 1764/p²
= 1764/36
Q = 49
