Answer:
21/2 or 10.5
Step-by-step explanation:
5x - 3y
5(5/2) - 3(2/3)
25/2 - 2
25/2 - 4/2
21/2
36 / k+3 = 44 / k+5
crossmultiply:
44k + 132 = 36k + 180
8k = 48
k = 6
? / 6 = 44 / 11
? / 6 = 4 / 1
cross multiply:
? = 24
Answer:
At 1:40 pm you will reach the market.
Step-by-step explanation:
Distance (d) = 11 km
Average speed (v) = 3 km/h
Formula:
It will take 3 hours 40 minutes to reach the market.
So, if you set off for the market at 10 am you will reach market by 1:40 pm (10 am + 3hr 40min).

4(x + -3) = 7x + 24
Reorder the terms:
4(-3 + x) = 7x + 24
(-3 * 4 + x * 4) = 7x + 24
(-12 + 4x) = 7x + 24
Reorder the terms:
-12 + 4x = 24 + 7x
Solving
-12 + 4x = 24 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
-12 + 4x + -7x = 24 + 7x + -7x
Combine like terms: 4x + -7x = -3x
-12 + -3x = 24 + 7x + -7x
Combine like terms: 7x + -7x = 0
-12 + -3x = 24 + 0
-12 + -3x = 24
Add '12' to each side of the equation.
-12 + 12 + -3x = 24 + 12
Combine like terms:
-12 + 12 = 0
0 + -3x = 24 + 12
-3x = 24 + 12
Combine like terms: 24 + 12 = 36
-3x = 36
Divide each side by '-3'.
x = -12
Simplifying
x = -12</span>
Answer:
Step-by-step explanation:
From the image (or by just looking at the equations and know what each part represents) you can tell the solution is (0;2)
Analitically, you already have them in a form, so let's compare the two RHSs: . Let's replace the value in either to find
