Anton [14]3 years ago
5 0

Answer:

5(5x-t)

=13×5

25x - 5t

=65

25x -5t + 4x +5t

=65 + 22

29x

= 87

x

= 87÷29

x =3

substituting x=3 in 5x-t=13

15- t

=13

15 - 13

= t

t = 2

A dessert has both fruit and yoghurt inside.
Rudiy27

note: f=fruit

y=yoghurt

2:3

f : y

f/y=2/3

=> 3*f=2*y

f=(2*y)/3

we know that f+y=185g

(2*y)/3+y=185g

(2*y+3*y)/3=185g

5*y/3=185

y=(185*3)/5

y=111g

=>the mass of the yoghurt is 111 g

What is the antiderivative of 3x/((x-1)^2)
ValentinkaMS [17]

Answer:

3 ln(x − 1) − 3/(x − 1) + C

Step-by-step explanation:

∫ 3x / (x − 1)² dx

3 ∫ x / (x − 1)² dx

If u = x − 1, then x = u + 1, and du = dx.

3 ∫ (u + 1) / u² du

3 ∫ (1/u + 1/u²) du

3 (ln u − 1/u + C)

3 ln u − 3/u + C

Substitute back:

3 ln(x − 1) − 3/(x − 1) + C

Simplify the expression: –3(–7 + 3z)
aleksandrvk [35]

Hey there! I'm happy to help!

We want to multiply each term inside the parentheses by the number on the outside.

-3(-7)=21

-3(3z)=-9z

Therefore, our expression is 21-9z.

Now you know how to use the distributive property! Have a wonderful day! :D
