LET THE DIMENSIONS BE X AND Y
2(L+B)=52
2(X+Y)=52
X+Y=26
X=26-Y
L*B=153
X*Y=153
26-Y*Y=153
26Y-Y^2=153
Y^2-26Y+153=0
Y^2-17Y-9Y+153
Y(Y-17)-9(Y-17)
(Y-9)(Y-17)
EITHER Y=9 OR Y=17
IF Y =9
X=15 M
IF Y=17
X=9M
SO DIMENSIONS ARE
(15 &9) (9 &17)
MARK IT BRANLIEST PLZ........
Answer: .
Step-by-step explanation:
Total amount remaining = Initial amount in the card-( Cost per cup × (Number of cups) )
Each cup of coffee costs $1.50 and after buying 4 cups of coffee, the card had a $9 remaining balance.
i.e. 9 = Initial amount in card - (1.50 × 4)
⇒ 9 = Initial amount in card - (6)
⇒ Initial amount in card = 9+-6 =15
⇒ Initial amount in card = $15
Let A be the amount money remaining on the card after buying x cups of coffee.
So, A = 15 - 4x
Hence, the required equation is .
We need more information or a picture please :)
x=2.5
Step-by-step explanation:
x+3.5/4=2(2x+2)/4
x+3.5=2x+2/2
x-2x+3.5=1
-x=(-3.5)+1
-x=(-2.5)
-x/(-1)=(-2.5)/(-1)
x=2.5
