**Step-by-step explanation:**

**We are expected to solve for the total number of balloons they can get with $100**

given that the expression for the total cost of balloons is given as

2b+12<100

We can proceed to solve for the total number of balloons they can buy, by solving for b we have

2b+12=100

2b=100-12

2b=88

divide both sides by 2 we have

2b/2=88/2

b= 44

Therefore they would get a total of 44 balloons

What is the slope of the line that passes through the points (-5,7) and (10, 1)?

А

m = 5/2

B

m = -5/2

С

m = -2/5

D

m = 2/5

y= -2/5x + 5 is the equation, so the correct answer would be c

The **points **are (-5,7) and (10,1). The slope of the points is -2/5.

Any two different points on a line can be used to calculate the slope of any line. The slope of a line formula is used to determine the ratio of "**vertical change**" to "**horizontal change**" between two different points on a line.

Given that,

The points are (-5,7) and (10,1).

We have to find the slope of the points.

The **relationship** between how a line's y coordinate changes and how its x coordinate changes determines a line's slope. y and x are the net changes in the y and x coordinates, respectively. As a result, the change in y coordinate with regard to the change in x coordinate can be written as,

**Slope** of the points=[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Here,

x₁=-5,

y₁=7

x₂=10

y₂=1

Slope of the points [tex]= \frac{1 - 7}{10 + 5}[/tex]

Slope of the points =(-6)/(15)

Slope of the points = -2/5

Therefore, the slope of the points is -2/5.

Employees at a medical supply company are mixing saline solution for use in IVs. They start with 50 liters of 12% solution. To this, they plan to add 10% solution. How many liters of the 10% solution should they add in order to obtain a finished product that is 11% saline?

Answer:

50 liters of the 10% solution should be added

Step-by-step explanation:

Here, we want to calculate the number of liters of the 10% solution that should be added

Let the number of 10% solution to be added be x liters

So total liters is now x + 50

Thus;

50 liters of 12% + x liters of 10% = (x + 50) liters of 11 %

Hence

12/100 * 50 + 10/100 * x = 11/100 * (x + 50)

0.12(50) + 0.1(x) = 0.11(x + 50)

6 + 0.1x = 0.11x + 5.5

6 - 5.5 = 0.11x - 0.1x

0.5 = 0.01x

x = 0.5/0.01

x = 50

It’s number 6. I’ll give brainliest

answer: $12

explanation:

we know that 2 CDs and 6 DVDs cost $156 and 1 CD and 9 DVDs cost $210.

this gives us the equations:

2x + 6y = 156

and

1x + 9y = 210

where x is CDs and y is DVDs

multiply the top equation by 9 and the bottom by -6 to solve for x:

18x + 54y = 1404

-6x - 54y = -1260

add from top to bottom:

12x = 144

divide both sides by 12 to get:

x= $12

Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers. If necessary, use / for the fraction bar(s). ∆ABC and ∆FDE are congruent by the criterion. (Use the three-letter abbreviation without spaces.) The value of x is , and the value of y is .

*See attachment for the given diagram.

Answer:

∆ABC and ∆FDE are congruent by the SSS criterion.

The value of x is 11 and the value of y is 8

Step-by-step explanation:

Based on the Side-Side-Side (SSS) Congruence Theorem, ∆ABC and ∆FDE are congruent to each other. The 3 sides of ∆ABC are congruent to the 3 given sides of ∆FDE.

Thus:

AB ≅ DF

BC ≅ DE

CA ≅ FE

Find x:

Since BC ≅ DE, therefore measure of BC = measure of DE.

BC = x + 3

DE = 14

Thus,

x + 3 = 14

Subtract 3 from each side

x = 14 - 3

x = 11

Find y:

Since AB ≅ DF, therefore the measure of both sides are equal.

AB = 3

DF = x - y

Thus,

x - y = 3

Substitute x = 11 into the equation

11 - y = 3

Subtract 11 from both sides

-y = 3 - 11

-y = -8

Divide both sides by -1

y = -8/-1

y = 8

A quadrilateral has coordinates of (-4,3), (-3,8). (2,5), and (1, -7).

Enter the perimeter of this quadrilateral rounded to the nearest whole unit.

**Answer:**

The perimeter of a quadrilateral will be equal to the addition of the length of each side of the quadrilateral.

Here we only have the vertices of the quadrilateral, and to calculate the length of the sides, first we need to plot the points in a graph and see which pairs make the quadrilateral.

You can see the image below, where i did a rough sketch of the problem.

in the image, you can see that the sides of this rectangle are the ones formed by the pairs:

(-4,3) and (-2, 8)

(-2, 8) and (2, 5)

(2,5 ) and (1, -7)

(1, - 7) and (-4, 3)

Now let's calculate the length of each side.

Remember that when we have two points (a, b) and (c, d) the distance is:

D = √( (a - c)^2 + (b - d)^2)

Now we need to calculate four distances:

**(-4,3) and (-2, 8)**

D1 = √( (-4 + 2)^2 + (3 - 8)^2) = 5.39

**(-2, 8) and (2, 5)**

D2 = √( (-2 - 2)^2 + (8 - 5)^2) = 5

**(2,5 ) and (1, -7)**

D3 = √( (2 - 1)^2 + (5 + 7)^2) = 12.04

**(1, - 7) and (-4, 3)**

D4 = √( (1 +4)^2 + (-7 -3)^2) = 11.18

Now we add those four distances to get the perimeter:

P = 5.39 + 5 + 12.04 + 11.18 = 33.61

And we want to round it to the next whole number, because the first digit after the decimal point is larger than 5, we round up, and get:

p = 37
