Answer:
x = -2
y = 1
Step-by-step explanation:
x−2y=6
<em>Multiply both sides by 2</em>
x-4y=12
<em>Subtract x from both sides</em>
-4y=12-x
2x−4y=10
<em>Subtract 2x from both sides</em>
-4y=10-2x
Put the 2 equations together:
12-x=10-2x
<em>Add x to both sides</em>
12=10-x
<em>Subtract 10 from both sides</em>
2= -x
<em>Multiply both sides by -1</em>
x= -2
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
x−2y=6
<em>Multiply both sides by 2</em>
2x-2y=12
<em>Add 2y to both sides</em>
2x=12+2y
2x−4y=10
<em>Add 4y to both sides</em>
2x=10+4y
Put the 2 equations together:
12+2y=10+4y
<em>Subtract 10 from both sides</em>
2+2y=4y
<em>Subtract 2y from both sides</em>
2=2y
y=1
Answer:
the right answer is a) 23
Step-by-step explanation:
because when we analyze the sequence it is observed that all the numbers are added the value of 3, therefore when arriving at position 10 the sum is 23
Answer: x<-1
Step-by-step explanation:
The answer is A!
Answer:
10 6/8 or 10 3/4
Step-by-step explanation:
Calculate out how many times the denominator goes into the numerator. To do that, divide 86 by 8 and keep only what is to the left of the decimal point:
86 / 8 = 10.7500 = 10
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
86 - (8 x 10) = 6
Keep the original denominator and use the answers from Step 1 and Step 2 to get this:
10 6/8
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 2, which is the greatest common factor, to get the final answer. 86/8 as a Mixed Number is:
10 3/4
