Their sum of ages is 45
So
x+x+27=452x+27=452x=18x=9Therefore
Nabil is 9years oldTala is 36 years oldStep-by-step explanation:
let the tala's age be x and nabil's be y
x+y=45(equation 1)
x=y+27
x-y=27(equation 2)
solving 1 and 2 equation
x+y=45
x-y=27
______
2x=18
x=9
therefore the talas age is 9
putting the value of x in equarion 1
9+y=45
y=45-9
y=36

Answers
Answer:
Part A: (4x+3) (4x+3)
Part B: 4 (x+y) (x-y)
(If this is not the answer you are looking for, sorry)
Step-by-step explanation:
Part A: (16x²+24x+9)
FOIL
(4x + 3) (4x +3) = 16x²+24x+9
(4x) (4x) = 16x²
(4x) (3) = 12x
(4x) (3) = 12x
12x + 12x = 24x
(3) (3) = 9
Part B: (4x²-4y²)
4 (x² - y²)
You have to factor it completely
4 (x + y) (x - y)
(Make sure to use FOIL to double check)

Divide:
72.8/364
Answer:
.20
Convert:
.20=20%
The shopkeeper giving 80% discount on the Christmas tree during the sale.
What is discount?A discount is an amount that is subtracted from the regular price of an item.

Let me know if you found this helpful! It means a lot!
2148.9 m^3
Explanation:
The formula for the volume of a sphere is V=πr^2h
We know that r, the radius, is 6 metres.
We also know that h, the height is 19 metres.
If we substitute those values into the formula, we get 2148.85 m^3.
And 2148.85 to the nearest tenth is 2148.9 m^3.

The expression to represents the amount of money Dion spent on fruit is as follows:
let
x = cost of each pounds of oranges
y = cost of each pounds of grapefruit
Therefore,
total cost = 3x + 2y
Let's evaluate the expression
total cost = 3(0.99) + 2(1.59)
total cost = 2.97 + 3.18
total cost = 6.15 dollars

A company is designing a new cylindrical water bottle. The volume of the bottle will be 176 cm ^3. The height of the water bottle is 7.8 cm. What is the radius of the water bottle? Use 3.14 for pi
Answers
Step-by-step explanation:
volume = 176 cm³
height = 7.8
radius = ?
pi = 3.14
volume of cylinder = πr²h
176 = 3.14 × r² × 7.8
176 = 24.492 × r²
176/24.4 = r²
7.21 = r²
√7.21 = r². ( Using long division )
r = 2.69 ( approx. )

What is the value of `x` in the solution of the system of equations?`3x-2y=6``\ \ x+2y=10`
Answers
Answer:
x = 4
Step-by-step explanation:
3x - 2y = 6 → (1)
x + 2y = 10 → (2)
add (1 ) and (2) term by term to eliminate y
(3x + x) + (- 2y + 2y) = 6 + 10 , that is
4x = 16 ( divide both sides by 4 )
x = 4

Answer:
S = R θ where θ is in radians
If θ = 2 pi then S = 2 pi R the circumference of the circle
θ = S / R = 9.7 / 9 = 1.08 rad

the angle included = 1.08 rad * 57.3 deg/rad = 61.9 deg
the chef mixed a seasoning that costs $3 per ounce with a seasoning that costs $1.75 per ounce to create a 24-ounce mixture that costs $2 per ounce. how many ounces of the $3 per ounce seasoning did he use?
Answers
Answer:
4.8 ounces
Step-by-step explanation:
X= number of ounces for the $3.00 mixture of seasoning
$3.00/OZ + $1.75/ OZ = $2.00/ OZ We are adding the seasonings together to produce the 24 OZ mixture
X + 24-X = 24OZ To get the missing term we will subtract what we have from X
100 [(3.00)(X) + (1.75)(24-X)] = [(2.00)(24)] 100 to get rid of the decimals multiply both sides by 100
(300)(X) + (175)(24-X) = (200)(24) Multiply on each side, removing the parenthesis
300X + 4,200 - 175x = 4,800 Get all of the X's on one side of the equation remember to change the sign of 4,200
300X - 175X = 4,800 - 4,200 Combine Like Terms
125X = 600 Get X alone
125 125 To get X, we will divide both sides by 125
X = 4.8 OZ
The chef used 4.8 ounces of the $3.00 seasoning
