2 answers:

6 0

You cant solve y but you can form an equation in terms of y
which is y=7-2x

if you were given another equation that has the term y and x than you can solve it.also that is a simultaneous equation.

Hope this helps,dont forget to put this as the brainliest answer if it does to help me out too. xD

Inga [223]

Answer:

theta = 60

Step-by-step explanation:

let the radius BE R

and angle be theta

formula

theta/360 x pi r2= 1/6 x pi r2

pi r2 gets canceled on both sides

theta/360 = 1/6

theta = 360/6

= 60

Which pairs are like terms in expression 2/5y + 1/5x - 0.2y - 6 + (-2)

Gelneren [198K]

The pair of like terms are:

$\frac{2}{5}y \text{ and } -0.2y$

Solution:

Given expression is:

$\frac{2}{5}y + \frac{1}{5}x -0.2y-6+(-2)$

We have to find the pairs that are like terms in the given expression

Like terms means that, terms that have same varibale but different ( or same ) coefficients

Here in the given expression "x" and "y" are the two variables present

Arrange the like terms

$\frac{2}{5}y-0.2y+\frac{1}{5}x-6+(-2)$

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms

"x" is present only once . There is no other term with variable "x"

6 and -2 are constants

So the pair of like terms are: $\frac{2}{5}y \text{ and } -0.2y$

Answer:

Step-by-step explanation:

a) (2,350),(5,530)

b) (530-350)/(5-2)=60

c) y=60x+b, using point (2,350)

350=60(2)+b

b=230

w=60t+230

c) w(7)=60(7)+230

w(7)=$650
