[(a+3)x8+26]:5=18 va multumesc frumos
Answers
multiply out
[8a+24+26]/5=18
add
(8a+50)/5=18
bultiply both sides by 5
8a+50=90
subtract 50 from both sides
8a=40
divide both sides by 8
a=5

Answer:
B. -6
Step-by-step explanation:
hope this helps!
Answer:
-6
Step-by-step explanation:
from (-6,-4) to (x,8) there are already 12 spaces in between the y- axis from -4 to 8. So because there are already 12 spaces in between you dont need to add any space between x and -6 so you can conclude that if x is -6 then there will be 12 spaces inbetween because of -4 and 8

do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7

length is 2(8)-3 which is 13 and width is 8
Answer:
l = 13 m
Step-by-step explanation:
Let's call the width of the rectangle x. Then we can form an expression for the length of the rectangle: 2x - 3
Now we need to form an equation for the area of the rectangle and solve it:
x(2x - 3) = 104
2x² - 3x = 104
2x² - 3x - 104 = 0 - now we need to factorize the equation
(2x + 13)(x - 8) = 0
Now we can say that x = 8 or x = -6.
Because we cannot have a negative length, x = 8 m.
Now we can workout the length using the expression that we formed at the beginning:
2x - 3 = l
2(8) - 3 = l
l = 16 - 3
l = 13 m

Exactly the way you do it with numbers:
-- List all the factors of the first one.
-- List all the factors of the second one.
-- List all the factors of the third one.
-- Make a short list, consisting of the factors that appear
on all three lists. Those are the 'common' factors.
-- The greatest item on the short list is the greatest common factor.
14m², 27a³, and 45a² don't have any common factor except ' 1 '.
Since ' 1 ' is their only common factor, it's also their greatest one.

x + 2y = 9
Answers
Answer:
x=-1 y=5
Step-by-step explanation:
A. 4x+y=1 multiply the equation negative 2
B. x+2y=9
-8x-2y=-2 add this to equation b
x+2y=9
-7x=7 divide both sides by -7
x=-1
now substitute x for -1 in either of the original equations
-4+y=1 add 4 to both sides
y=5
-4+5=1
-1+10=9
