Answer: 1, 10
Step by step explanation:
Assuming the given is: 5u^7 - 21u^7
Since both algebraic terms are identical (both are using u^7), we can subtract the coefficients directly, as in: 5 - 21 = -16
Therefore, 5u^7 - 21u^7 = -16u^7
Answer:
Thus, the value of x is 1.
Step-by-step explanation:
4(2x+6)=32
8x+24 =32
8x =32-24
8x =8
x =8÷8
x =1
Answer:
L (-2, -3) K(-2,-4) I (3,-1) J (2,-4)
Step-by-step explanation:
34 = 6x + 12.5y
3.5 = x + y
From the second equation you can find either x or y
x = 3.5 - y
Then you substitute x in the first equation with 3.5 - y
34 = 6(3.5 - y) + 12.5y
34 = 21 - 6y + 12.5y
13 = 6.5y
y = 2
So if y = 2 ...
3.5 = x + 2
x = 1.5
So she ran for 1.5 hours and biked for 2 hours
