X + 7 = - 3
x = - 3 - 7
x = - 10

Now put the value of x in 2nd equation,
- 10 - y = -3
- y = - 3 + 10
- y = 7
y = - 7

An advertising company charges $60 per half-page advertisement and $100 per full-page advertisement. Michael has a budget of $13
krek1111 [17]

Answer:

The number of half-page advertisements is 4.

The number of Full-page advertisements is 11.

Step-by-step explanation:

According to the Question,

  • Given, An advertising company charges $60 per half-page advertisement and $100 per full-page advertisement. Michael has a budget of $1340 to purchase 15 advertisements.

Let, 'x' be the number of half-page advertisements and 'y' be the number of full-page advertisements.

  • Thus, 60x + 100y is the money charged, and given that he has a budget of $ 1340.

       60x + 100y = 1340

  • And, the number of advertisements is 15. So, the other equation is

       x + y = 15

Now, We have Two Equations,

60x + 100y = 1340 and x + y = 15

  • the solution of the system is Put x=(15-y) in Equation 60x + 100y = 1340

60 (15-y) + 100y = 1340

900 - 60y + 100y = 1340

40y = 1340 - 900

40y = 440

y = 440/40

y = 11 So, For x = 15 - y ⇒ 15-11 ⇒ x=4 .

  • Thus, the number of half-page advertisements is 4 and The number of Full-page advertisements is 11 .

List the components in the proportion relationship used to find missing value in scale drawing?
Phoenix [80]
<h2>Explanation:</h2><h2></h2>

When we have relationships between two variables and their ratios are equivalent, we call this as proportional relationship. A scale drawing is a model that has been reduced or enlarged from its original size. Suppose you have a horse that measures 1,5m high by 2m long and want to draw a reduced model by a scale factor of 1:10, then your drawing will measure:

Height=1.5(1/10)=0.15m \\ \\ Length=2(1/10)=0.2m

So the components are:

  • Measurements of the original object
  • Measurements of the drawing
  • Scale factor
