Answer:
Option A
x=6 , y=9
Step-by-step explanation:
As we can see in the figure that point T is the mid point of rectangle and there are two diagonals QS and PR
So in basic geometry we know that the length of the diagonal from the mid point i.e. Taking the diagonal QS the length of QT and TS would be equal because they are same diagonal which is cut into two parts by point T
Similarly the Length of RT and the length of TP would be same
From all this we deduct that
3x = 2y ..................(i)
and
y + 3 = 2x ................(ii)
From equation (i)
3x = 2y
Dividing both sides by 3 the equation becomes
x=
....................(iii)
Putting this value in equation (ii)
y + 3 = 2(
)
y+3 =
multiplying both sides by 3
3(y+3)=
the equation becomes
3y+9=4y
subtracting 3y from both sides
3y-3y+9=4y-3y
y=9
Putting the value of y in equation (iii)
x= 
solving it
x= 
x=6
so x=6 and y=9 is answer which is option A
Answer:
5:15
Step-by-step explanation:
15:55 = 3:55 in normal time
3:55 + 1 hr = 4:55
4:55 + 20 min = 5:15
Answer:
3^2*3^4
3^12/3^4
(3^4)^2
The first, fourth, and fifth
Step-by-step explanation:
Follow rules of exponents
When multiply an exponent with same base just add the exponents
EX: 2^2 * 2^2= 2^4
When dividing with the same base, subtract
EX: 3^12/3^2=3^10
When raising the power of an exponent to another exponent, multiply.
EX: (3^2)^2=3^2
I want to say 56.4 or 56.42
Answer:
4. 54- 8.5x>20
Step-by-step explanation:
Catherine only has $54, so she cannot spend more than that.
The canvas will cost at least $20, but we don't know how much exactly.
The tubes cost $8.50 each.
So, she starts with a total budget of $54, out of which she will buy paints (8.5x) and she wants to have at least $20 left for canvas.
So, we transpose those facts into the inequity:
54 - 8.5x > 20
