Answer:
Sara is 10 and Laila is 8Step-by-step explanation:
Sara's age = sLaila's age = lThe ratios:
s/l = 5/4 ⇒ s = 5l/4(s + 2)/(l + 2) = 6/5 ⇒ 5(s + 2) = 6(l + 2) ⇒ 5s = 6l + 2Substitute s into the second equation and solve for l:
5(5l/4) = 6l + 225l = 24l + 8l = 8Fins s:
s = 5*8/4 = 10Which of the following statements about rational numbers is not correct? А All whole numbers are also rational numbers. B All rational numbers can be written in the form where b=0. b.wh C Rational numbers cannot be negative. D All integers are also rational numbers.

Consider the following geometric sequence
-5, 20, -30, 40, ...
If the explicit formula for the sequence above is expressed in the form aₙ = b*c^n-1, determine the values of b and c.
Answer:
b = -5 and c = -4
Step-by-step explanation:
The common ratio here is r = 20/(-5), or -4, and the first term, a(1), is -5. Thus, the explicit formula is
a(n) = a(1)*r^(n -1) (must use parentheses, as shown)
and so we have a(n) = -5*(-4)^(n - 1). b = -5 and c = -4
Can someone explain this step by step please
Answer:
2
Step-by-step explanation:
Since x=-2
-2+3y=4
Add 2 on both sides
3y=6
Divide 3 on both sides
y=2
Answer:
x is equal to -2
the equation is x + 3y = 4
so we substitute the value of 'x' which is -2 in equation x + 3 = 4
Step-by-step explanation:
then we move 3y on left side.
then we add 4 + 2 which is 6.
then it will be, y = 6/3
which is 2
therefore we get y = 2

A rectangular ink pad has a permieter of 26 cenimeters. Ts area is 40 square cenimeters. What are the deminitions of the ink pad
Answer: 5cm and 8cm
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
Area of a rectangle = l × w
where l = length
w = width
Therefore,
2l + 2w = 26 ...... i
l × w = 40 ...... ii
We can reduce equation i to l + w = 13.
l + w = 13 ....... i
l × w = 40 ....... ii
From i, l = 13 - w ...... iii
Put the value of l into equation ii
l × w = 40
(13 - w) × w = 40
13w - w² = 40
13w - w² - 40 = 0
w² - 13w + 40 = 0
w² -8w -5w +40 = 0
w(w - 8) -5(w - 8) = 0
(w - 5) = 0 and (w - 8) = 0
w = 0 +5 and w = 0 + 8
w = 5
l = 8
The dimensions are 5cm and 8cm

please... help me..I have a confusion..
is the (-5 + -3 ) is =( -5 - +3)
Answer:
They are the same
Step-by-step explanation:
We are to check if (-5 + -3 ) =( -5 - +3)
First you must know that the product of a positive and a negative n=sign will result in a negative sign i.e. + * - = -
Applying this in question;
(-5 + -3 )
= -5 - 3
= -8
similarly
( -5 - +3)
= -5 - 3
= -8
Since both values are the same hence, (-5 + -3 ) =( -5 - +3)

Find mzS. It’s geometry I need help
Answer:
151
Step-by-step explanation:
So you have to start by finding the total number of degrees inside the shape. The shape has 5 sides.
So using this formula:
(n-2) * 180
(5-2) * 180
= 540 degrees inside the shape
Then solve for x.
5x +2 + 10x - 3 + 8x -19 + 13x - 31 + 7x -11 = 540
43x -62 = 540
43x = 602
x = 14
Plug in for S.

A 12 foot by 8 foot rug covers the hardwood floor of a room. The rug leaves a uniform
strip of bare floor surrounding the rug. If the area of the room is twice the area of the
rug, what is the equation you will use to solve for x?
Answer: 2(12 × 8)
Step-by-step explanation:
The area of the rug will be gotten by multiplying the length by its width. This will be:
= 12 foot × 8 foot
= 96feet²
Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:
= 2(12 × 8)
= 2(96)
= 192feet²
