P = 2w + 2l
326 = 2w + 2(99)
326 = 2w + 198
128 = 2w
w = 64
the width is 64cm
Answer:
c + 190 = Weight of the lion
Step-by-step explanation:
----------------------------------------------------------------
Define x:
----------------------------------------------------------------
Let the number be x
----------------------------------------------------------------
Construct Equation :
----------------------------------------------------------------
x- 18 = 7x
----------------------------------------------------------------
Take away x from both sides :
----------------------------------------------------------------
-18 = 7x - x
----------------------------------------------------------------
Combine like terms :
----------------------------------------------------------------
-18 = 6x
----------------------------------------------------------------
Switch sides :
----------------------------------------------------------------
6x = -18
----------------------------------------------------------------
Divide by 6 on both sides :
----------------------------------------------------------------
x = -3
----------------------------------------------------------------
Answer; The number is -3.
----------------------------------------------------------------
4y - 3 = y + 6
Add 3 to both sides
4y = y + 9
Subtract y from both sides
3y = 9
Divide both sides by 3
y= 3
= (5 - 9i) + (-4 + 7i) - (14 - 3i)
Combine like terms; two negatives make a positive when you remove parentheses
= (5 + -4 + -14) + (-9i + 7i + 3i)
= -13 + 1i or -13 + i
ANSWER: -13 + i (first choice)
Hope this helps! :)
