Answer: 8.361599999999999 x 10 2
Step-by-step explanation:
<h3>I'll teach you how to solve (1/5x-4+2y)+(2/5x+5-4y)</h3>
-----------------------------------------------------------------
(1/5x-4+2y)+(2/5x+5-4y)
Remove parentheses:
1/5x-4+2y + 2/5x+5-4y
Group like terms:
1/5x+2/5x+2y-4y-4+5
Add similar elements:
3/5x+2y-4y-4+5
Add similar elements:
3/5x-2y-4+5
Multiply:
3x/5-2y-4+5
Add subtract the numbers:
3x/5+1-2y
Your Answer Is 3x/5+1-2y
plz mark me as brainliest :)
Answer:
a = 4/27 - b/54
Step-by-step explanation:
27a+1/2b=4
Subtract 1/2 b from each side
27a+1/2b - 1/2 b=4-1/2 b
27a = 4 - 1/2 b
Divide each side by 27
27a/27 = 4/27 - 1/2 b/27
a = 4/27 - b/54
It’s the second option, (x,y) —> (3x,3y) since you have to multiply each coordinate by a certain number called the scale factor (in this case, it’s 3)
The first option won’t work because the scale factor has to be same for both coordinates. The third option is a translation, and the fourth won’t work either because you have to multiply each coordinate by the same variable.
Answer:
j =76/3
Step-by-step explanation:
-3j - -4
------------------ = 12
-6
Multiply each side by -6 to clear the fraction
-3j +4
------------------ * -6 = 12 *-6
-6
-3j +4 = -72
Subtract 4 from each side
-3j +4-4 = -72 -4
-3j = -76
Divide each side by -3
-3j/-3 = -76/-3
j = 76/3
