Answer:

Given :

Cost of onsite repair = 3 times cost of at store

cost of mai services = cost of at store -10

On-site work completed last week = 15

At store work completed = 40

mail work completed = 5

Let's Assume :

The cost of at store = x

the cost of in-site = 3x

the cost of mail service = x-10

Solution :

Part 1] :

See the "let's Assume" part

The cost of at store = x

the cost of in-site = 3x

the cost of mail service = x-10

Part 2 ]

The equation that can be formed is :

15(3x)+40(x)+5(x-10) = 2650 ,

or, 45x+40x+5x-50 = 2650

or, 90x = 2700

Part 3]

To determine the cost of on-site work, we will solve the equation formed in "Part 2"

So, 90x = 2700

or, 9x = 270

or, x = 270/9

or, x = 30

So,

The cost of on site repair = ₹90

The cost of at store = 30

The cost of by mail service = 20

Hope it helped Freind !

Find the value of p for which x = -2, y = -1 is a solution of linear equation 5x + 2py = 2p.​
Rom4ik [11]
I think p=4
How I solved it:
5(-2)+2p+2(-1)=2p
-10+2p+-2=2p So cross out last
-2p -2p 2p:)
= -10+2p+-2
+10 +10 Cross out the 10
= 2p=8
= divide both sides by 2p
= 2p/2= 8/2
= cross out the 2.
= which leaves
= p=4 we get 4 because we divide 8 to 2:)


I don’t know if I’m right but yea...

1/3 of students at a school are boys. If there are 600 students at the school, how many are girls?

Answer:

200 students are boys and rest of 400 are girls

Step-by-step explanation:

Given that:

Total students = 300

1/3 students of total are boys

so.

Boys = 1/3(600)

Boys = 200

For finding number of girls:

Girls = total - boys

Girls = 600 - 200

Girls = 400

IM STCK PLZ HELP!!! THANK YOU :)
lesya [120]

Answer:

x = 81, y = 68 and z = 99

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

z is an exterior angle, thus

z = 63 + 36 = 99

x and z form a straight angle and are supplementary, so

x + z = 180, that is

x + 99 = 180 ( subtract 99 from both sides )

x = 81

The sum of the 3 angles in a triangle = 180°, thus

z + y + 13 = 180, that is

99 + y + 13 = 180

112 + y = 180 ( subtract 112 from both sides )

y = 68
