AysviL [449]3 years ago
3 0

Answer:

<h2>y = 9</h2>

Step-by-step explanation:

Put x = 5 to the equation -6x - 3y = -57

(-6)(5) - 3y = -57

-30 - 3y = -57            <em>add 30 to both sides</em>

-3y = -27           <em>divide both sides by (-3)</em>

y = 9

8 miles in 0.5 hour what rate in miles per hour
yan [13]
In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
In 1 hour the person covers a distance of = 8/0.5 miles
                                                                   = 16 miles
So the speed of the person in miles per hour = 16/1 miles/hour
                                                                         = 16 miles per hour

Choose all the expressions that are equal to 0.7 × 0.41.
dlinn [17]

Answer:

None of the expressions is equal to 0.7 x 0.41.

Step-by-step explanation:

Given that 0.7 x 0.41 is equal to 0.287, to determine which options are equal to said operation, the calculations set out for each of them must be performed:

A. 7,100 × 41100 = 291,810,000

B. 710 × 41100 = 29,181,000

C. 7100 × 4110 = 29,181,000

D. 710 × 4110 = 2,918,100

E. 70100 × 41100 = 2,918,100,000

Therefore, looking at all the results produced by the predisposed calculations, it is evident that none of the expressions is equal to 0.7 x 0.41.

Ishi bought a canvas and 6 tubes of paint for $24.45. If the canvas cost $6.45, what equation would represent this problem?
DedPeter [7]

$24.95−$6.95=$18. Thus 8 tubes of paint cost $18.

$188=$2.25 for 1 tube of paint.

Explanation:

Once you remove the cost of the canvas from the total price, you're left with only the cost of the 8 tubes of paint.

This is represented by

$24.95−$6.95=$18

If 8 tubes of paint cost $18, then all we have to do is divide 18 by 8 to get the cost of each individual tube of paint.

Thus

$188=$2.25

is the cost for one tube of paint.

Hope this is helpful to you..
