Answer: x= 0.3 or x=3/10
Step-by-step explanation:
90x=27
divide both sides by 90
x=27/90 which simplfiyes to 3/10
x=0.3
The answer to question A is 0.18 B 3.75
Answer:
b
Step-by-step explanation:
Multiplying the first equation by -1 and adding it to the third, we get 2y-8z=15 and by multiplying the first equation by -1 and adding it to the second equation, we get -3y-4z=3
Using the two equations, we have
2y-8z=15
-3y-4z=3
Multiplying the second equation by -2 and adding it to the third, we have 8y=9 and y = 9/8 by dividing both sides by 8. Plugging it back into
-3y-4z=3, we have -27/8-4z=3 and by adding 27/8 to both sides, we have -4z=51/8 and by dividing both sides by -4 we get z=-51/32.
Plugging it into 2x − y + z =2, we get 2x-9/8+5(-51/32)=2, we get x=151/64 by adding -(5(-51/32)) to both sides as well as adding 9/8 to both.
