Answer: (-9,6)
Step-by-step explanation:
3x+2y=-15
2x=-18
First solve for x in second equation
2x=-18
2x/2=-18/2
X= -9
Now substitute your x into first equation to find y
3(-9)+2y= -15
-27+2y=-15
2y= -15+27
2y= 12
2y/2=12/2
Y= 6
Answer:
280
Step-by-step explanation:
<u><em>The question in English is</em></u>
Write the number that has the same value as 28 tens
we know that
One tens is equal to the number 10
so
To find out the value of 28 tens, multiply the number 28 by 10
Well actually depending on the size, if a small one I would use liters, but if a large ones like Olympics I would use kilolitres.
<span>The answer is 454. Since the value of the ones digit is 4, the last digit is a 4. Next, since the ones digit is the same as the hundreds digit, the first digit would be 4. Finally, the middle digit is the tens place and would be 5 since the tens digit is 50.</span>
