Answer: 110/3
Step-by-step explanation:
5x+15= 8x+2 = 13/3
5 * 13/3 + 15= 110/3
Answer: x=-7/2 y=29/2
Steps:
Use the elimination method
Multiply -3x+y=4 by 5 to make the coefficient next to the y in both equations the same
5(-3x+y=4)
-15x+5y=20
Then, subtract to eliminate the y
-15x+5y=20
- -9x+5y=-1
= -6x=21
Divide both sides by -6 to isolate x
= x= -7/2
Next substitute -7/2 into x in one of the equations
-3(-7/2)+y=4
-21/2+y=4
Add 21/2 from both sides to isolate y
y=29/2
Let makoha contribute x then njao contributes x * 3/2 = 1.5x
and odhiambo contributes 1.5x * 2.5 = 3.75 x
so we have the equation x + 1.5x + 3.75x = 120000
6.25x = 120000
x = sh 19,200 which is the amount for makhoa
Answer : amount contributed by odhiambo = 19,200 * 3.75 = sh 72,000
Answer:
Translation
Step-by-step explanation:
The circumference can be obtained fairly easily by simply substituting the d in c = πd for the colony's given diameter of 12 mm. Performing that calculation using the approximation of π ≈ 3.14, we obtain a circumference of 12 x 3.14 = 37.68 mm.
To find the radius, remember how the diameter and radius of a circle are defined. The radius is a length extending from the center of a circle to a point on its circumference, and a diameter is a line extending from one point on the circle's circumference to an opposite point, passing through the circle's center along the way. The diameter can, in this way, be defined as twice the length of the radius, which means we can find the radius of a circle by taking half of its diameter. In this case, our diameter is 12 mm, so our radius would be 6 mm.
