The two numbers are 31 and 35.

Step-by-step explanation:

Let,

one number = x

2nd number = y

According to statement;

x+y=66 Eqn 1

y=x+4 Eqn 2

Putting y=x+4 from Eqn 2 in Eqn 1;

$x+(x+4)=66\\x+x+4=66\\2x=66-4\\2x=62\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{62}{2}\\x=31\\Putting\ x=31\ in\ Eqn\ 2\\y=31+4\\y=35$

The two numbers are 31 and 35.

Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120

Aleksandr [31]

Answer: $\left \{ {{m=2d} \atop {m+d=120}} \right.$

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

d = kilograms of dark chocolate

m =kilograms of milk chocolate

So, her recipe calls for twice the amount of dark chocolate as milk chocolate.

Mathematically speaking:

m = 2d

She needs to buy 120 kg, of chocolate in total. So;

m + d = 120

The following system of equations represent the situation:

$\left \{ {{m=2d} \atop {m+d=120}} \right.$

Answer:

The coefficients are;

1,28,378 and 3,276

Step-by-step explanation:

For the binomial expansion, when we talk of the coefficients, we mean the whole numbers that stands before the alphabets

For example, the coefficient of x in 2x is 2

Back to the question;

(x + y)^28

= 28C0 x^28y^0 + 28C1 X^27y^1 + 28C2 x^26y^2 + 28C3 x^25y^3 + ..........

So the coefficients we are looking for are;

28C0 = 1

28C1 = 28

28C2 = 378

28C3 = 3,276

Kindly note that 28C0 is read as 28 combination zero and so on
