3/4 will become 1/2 and 6/7 will become 1/2 too
<span>9-4(2x-1)=45
Multiply -4 by 2x and -1
9-8x+4=45
Subtract 9 from both sides
-8x+4=36
Subtract 4 from both sides
-8x=32
Divide both sides by -8
Final Answer: x= -4</span>
Answer:
if you put 4.25 on a number line then the OPPOSITE of that would be going across the 0 on the number line so the answer -4.25
Step-by-step explanation:
if the number is negative its opposite is that number but positive and the same thing if the number is positive its opposite is a negative
Answer:
That guy is correct a because its both greater than and equal to 8
x is the number of adults and y is the number of children.
x + y = 12
<span>14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
</span>14x + 10y = <span>140
</span>-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = <span>12
</span>5 + y = <span>12
</span>y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
