Answer:
t = d/S
Step-by-step explanation:
S = d/t
Cross multiply
S x t = d
Divide both sides by S
S/S x t = d/S
t = d/S
The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"
<h3>System of equation</h3>
System of equation are made of two or more equations with unknowns
Given the system of equation
4x=5-2y
y-2x=7
From equation 2:
y = 7 + 2x
The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"

I have no idea what that is so sorry
The answer is 21 because times the bottom and top by 3 and 2 x 3 is 6 as there are 6 red pencils and 7 x 3 is 21.
Answer:
42
Step-by-step explanation:
3 x {[(12-8) x 2] + [(11 - 9) x 3]}
12-8=4 and 11-9=2.
3 x ((4 x 2) + (2 x 3))
4 x 2= 8 and 2 x 3=6.
3 x (8 + 6)
8 + 6 is 14.
3 x 14 is 42.
