Can someone help me with this math question? First to answer will get Brainliest! :)

Answer: x = 1 or x = 2

Sub in x for ?:

x^2-3x = -2 (Move all the terms to one side, and set the equation to equal 0)

x^2-3x+2 = 0 (Factor the simple trinomial by finding two numbers that multiply to 2 and add to -3)

x^2-x-2x+2 = 0 (Factor the expression)

x(x-1)-2(x-1) = 0 (Group like terms)

(x-1)(x-2) = 0 (Solve for x by setting each term equal to 0)

x-1 = 0

x = 1

x-2 = 0

x = 2

∴ x = 1 or x = 2.

Answer:

There were 15 small boxes shipped and 5 large boxes shipped.

Step-by-step explanation:

Let s = the number of small boxes shipped

Let l = the number of large boxes shipped

Each small box weigh 35 pounds, so (s) small boxes weigh 35s pounds. Each large box weigh 65 pounds, so (l) large boxes weigh 65l pounds. Therefore, the total weight 35s + 65l equals 850:

                                                 35s + 65l = 850

Since there were 3 times as many small boxes shipped as large boxes, there were MORE small boxes, so if we multiply 3 by the number of large boxes, we will get the number of small boxes, meaning s equals 3l

                                                  s = 3l

Write System of Equations:

                                                 35s + 65l = 850

                                                     s = 3l

Substitute value of s into the first equation:

35(3l) + 65l = 850

105l + 65l = 850

170l    850

__   =   __  

170      170

  l = 5

Since l = 5, we know 5 large boxes were shipped.

Use l = 5 to solve for s:

s = 3l

s = 3(5)

s = 15

Since s = 15, we know 15 small boxes were shipped.

Answer:

y = 1.5m

Step-by-step explanation:

Since we are finding the length after a certain number per month, that means we will be multiplying.

1.5 for EVERY month so it would look like

_ = 1.5m

We can replace the blank with the variable y.

y = 1.5m

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

Answer:

The correct choice is (c) $79.80

Step-by-step explanation:

The total charge for renting a car can be split into two parts:

A fixed one-time charge of $45

A variable charge of $0.29 per driven mile.

If I drive 120 miles, the variable charge will be 120*0.29 = $34.80

The total charge will be $45 + $34.80 = $79.80

The correct choice is (c) $79.80

The dollar amount of shoes she sold is $1800

It is the amount earned on a product bought or sold.

If  she receives a commission of 11.5% for each pair of shoes she sells and earned $207, the amount earned is calculated using the formula:

11.5% of x = 207

0.115x = 207

Divide both sides by 0.115

x = 207/0.115

x = $1800

Hence the dollar amount of shoes she sold is $1800

Step-by-step explanation:

Equilateral Triangle:

Side of triangle = breadth of rectangle

                         = 28 cm

height = 24 cm

Area of triangle = [tex]\frac{1}{2}base * height\\\\[/tex]

                          = [tex]\frac{1}{2}*28*24[/tex]

                          = 28* 12

                         =  336 square cm

Rectangle:

length = 50 m

breadth = 28 m

Area of rectangle = length * breadth

                              = 28 * 50

                              = 1400 square cm

Diameter of circle = breadth of rectangle

                        d  = 28 cm

                         r = 28/2 = 14 cm

Area of circle = πr²

                      [tex]= \frac{22}{7}*14*14\\\\= 22 * 2 * 14[/tex]

                     = 616 square cm

Area of the remaining portion =  Area of rectangle - area of circle + area of triangle

                                                    = 1400 - 616 + 336

                                                   = 1120 square cm

Perimeter of the figure = 28 + 50 + 28 + 28 + 50

                                       = 184 cm

Hint: Perimeter of the figure. three side of rectangle + two sides of triangle

Answer:

the desired equation is y = (-3/4)x - 1

Step-by-step explanation:

Start with the slope-intercept formula y = mx + b.

Substitute -4 for y, +4 for x and -3/4 for m:

-4 = (-3/4)(4) + b

Then -4 = -3 + b, so b must be -1

and the desired equation is y = (-3/4)x - 1

Step-by-step explanation:

An obtuse triangle will have two obtuse angle at its exterior.

Take for instance, the angles in the triangle are 100, 40 and 40.

The exteriors would be 80, 140, 140 (this is gotten by subtracting each interior angles from 180).

So, using the above analysis, we can conclude that the statement is possible.
