4x = -60 - 19y
-7x = -48 - 19y

Subtract the bottom equation from the top:
4x + 7x = -60 + 48 - 19y + 19y

Simplify:

11x = -12 -0y
11x = -12

Divide both sides by 11:
11x/11 = -12/11

Simplify:
x = -12/11
Then plug in x to solve for y: 4(-12/11) = -60 - 19y

Simplify: -48/11 = -60 - 19y

Add 60 to both sides (keep in mind 60 = 660/11):

-48/11 + 660/11 = -60 + 60 - 19y

Simplify:
612/11 = 0 - 19y
612/11 = -19y

Divide both sides by -19 (keep in mind that dividing by -19 is the same as multiplying by -1/19):
612/11 • -1/19 = -19y/-19

Simplify:
-612/209 = y
y = -612/209

So, the answer is: (-12/11, -612/209)

. On a recent business trip, a salesman traveled 52 miles the first hour, 64 miles the second hour and 49 miles the third hour.
igomit [66]

Remark

The average is found by adding the total miles and dividing by the total number of hours.

Average

total distance = 52 + 64 + 49

Total distance = 165 miles

Total time = 1 + 1 + 1 = 3 hours.

Average = total distance/ total time

Average = 165  /   3 = 55 miles per hour.

Five milliliters of a children s medicine contains 400 mg of the drug amoxicillin. How many mg of amoxicillin does 25 ml contain
Nonamiya [84]

Answer:

ok, so pretty much you can set up an equation for this. You can use fractions to find this out.

Step-by-step explanation:

<h2>\frac{5}{400} =\frac{25}{x}</h2><h2 /><h2>what you do is multiply 400*25 and then divide by 5. It should be 2000</h2>

Given: ∠A and ∠B are complementary angles.
Eddi Din [679]

Answer:

 - For the statement -3x=24, the reason is: <em>Subtraction property of Equality</em>

- For the statement x=-8, the reason is: <em>Division property of Equality.</em>

- For the statement m\angle B=-6(-8)-39, the reason is: <em>Substitution property of Equality.</em>

Step-by-step explanation:

The missing pictures are attached.

We must remember that:

- The Subtraction property of Equality states that:

If\ a=b,\ then\ a+c=b+c

- The Division property of Equality states that:

If\ a=b,\ then\ \frac{a}{c}=\frac{b}{c}

- The Substitution property of Equality states that:

 If\ a=b,\ then\ b\ can\ replace\ a

Knowing this properties we can identify the missing reasons that correctly complete the proof.

 - For the statement -3x=24, the reason is:

Subtraction property of Equality

(Because it is obtained by subtracting  66 from both sides of -3x+66=90)

- For the statement x=-8, the reason is:

Division property of Equality

(Because it is obtained by dividing both sides of  -3x=24 by -3)

- For the statement m\angle B=-6(-8)-39, the reason is:

Substitution property of Equality

(Because it is obtained by substituting the value of "x" into   m\angle B=-6x-39)
