Answer: =248x
Step-by-step explanation: Hope this help :D
Let's simplify step-by-step.
4x(10)+2x(104)
=40x+208x
Combine Like Terms:
=40x+208x
=(40x+208x)
=248x
Using the commutative property means that you could do 5x4=20 and flip it around so it’s 4X5 the answer would still be 20 but in a different order
A. -3 < x < 1
b. x < = 4 or x > = 6
Answer:
12
Step-by-step explanation:
This is a joint variation problem:
z varies directly as x and y
Interpreting this;
z ∝ xy
Therefore;
z = kxy
z = 6, x = 2, y = 6
Now find k,
6 = 2 x 6 x k
6 = 12k
k =
To find the value of z;
x = 3, y = 8
z =
x 3 x 8 = 12
