Answer:

(75x2)+(6-3)

These equations are in parentesis so they happen first.

75x2=150. If we take 70 and multiply it by 2 we get 140. If we multiply 5 by 2 we get 10. So 140+10=150.

6-3 is next. That is common knowledge and we know its 3.

No we add 150+3=153 to get our answer.

Parenthesis first

Exponets after parenthesis

Multiplying going left to right

Divinding left to right

Adding left to right

Subtracting left to right

Step-by-step explanation:

I hope this helped and if so plz give brainliest.

3/4 of Hari's marbles are black and 1/5 are green. What would be the ratio of black marbles to the green marbles?

Kazeer [188]

Answer:

➩ 15 : 4 is the ratio

Step-by-step explanation:

Hari's marbles are = ¾ which is black in color.

And ⅕ of his marbles are green in color.

Forming in ratio :

$\sf \to \: \frac{3}{4} : \frac{1}{5} \\ \sf \to \: \frac{3}{4} \times 5 \\ \sf \to \: \frac{15}{4} \\ \sf \to \: 15 : 4 \: ans.$

Consider the following.3x + 3y = 8(a) Find y' by implicit differentiation.(b) Solve the equation explicitly for y and differenti

ludmilkaskok [199]

Answer:

a.y'=-1

b.y'=-1

c.Yes

Step-by-step explanation:

We are given that consider a function

$3x+3y=8$

Implicit function: That function is a relation in which dependent variable can not be expressed in terms of independent variable

Explicit function: It is that function in which dependent variable can be expressed in terms of independent variable.

a. $3x+3y=8$

Differentiate w.r.t x then we get

$3+3\frac{dy}{dx}=0$

$3\frac{dy}{dx}=-3$

$\frac{dy}[dx}=\frac{-3}{3}=-1$

$\frac{dy}{dx}=y'=-1$

b. $3x+3y=8$

$3y=8-3x$

$y=\frac{8-3x}{3}$

Differentiate w.r.t x then we get

$\frac{dy}{dx}=\frac{-3}{3}=-1$

$\frac{dy}{dx}=y'=-1$

When we substituting the value of y obtained from part b into a solution of part a then we get

$y'=-1$

Hence, solutions are consistent.

5t-14=-14<br> solve the equation for t

ikadub [295]

Hi there!

Before we begin, let's rewrite your equation. :)

$5t - 14 = -14$

Step 1) Add 14 to both sides.

$5t - 14 + 14 = -14 + 14 5t = 0$

Step 2) Divide both sides by 5.

$\frac{5t}{5} = \frac{0}{5}$

$t = 0$

Final Answer -

$t = 0$

Hope this helps!
