If the triangles in the diagram are congruent, then x is equal to 30°.
True or false

Answer:

x = -8/5 = -1 3/5

Step-by-step explanation:

2{x-3}+3{x+3}={-5}

Expanding the brackets:

2x - 6 + 3x + 9 = -5

5x = -5 + 6 - 9

5x = -8

x = -8/5.

Answer:

x=-8/5 is your answer

Step-by-step explanation:

2{x-3}+3{x+3}={-5}

2x-6+3x+9=-5

5x+3=-5

5x=-5-3

x=-8/5

Step-by-step explanation:

Like terms have the same variables with the same exponents on each variable. Add their coefficients, and keep the same variables and exponents.

Answer:

Step-by-step explanation:

1. is y= 3 x +8

-3 x +  y - 8= 0

y = 3x+ 8

2. is in the pictures

3.

3 X + 5 y - 10 = 0

Real solution:

y = 2 - (3 X)/5

Solution:

y = 2 - (3 X)/5

Integer solution:

X = 5 n, y = 2 - 3 n, n element Z

Solution for the variable y:

y = 1/5 (10 - 3 X)

Step-by-step explanation:

Answer:

taco:  $1.49 each

burrito:  $1.79 each

Step-by-step explanation:

Let b = cost of one burrito

     t =  cost of one taco

(1)     3b  + 4t  = 11.33              (2)     9b + 5t = 23.56

Multiply (1) by -3 and add to (2)     -9b - 12t = 33.99

                                                              - 7t = - 10.43

                                                                  t = 1.49

       3b + 4(1.49) = 11.33

          3b + 5.96 = 11.33

                  3b = 5.37

                    b = 1.79

Answer:

84 Sq in

Step-by-step explanation:

area of the composite figure = Area of square + Area of triangle

[tex] = {9}^{2} + \frac{1}{2} \times (9 - 7) \times 3 \\ \\ = 81 + \frac{1}{2} \times 2 \times 3 \\ \\ = 81 + 3 \\ \\ = 84 \: {in}^{2} [/tex]

Step-by-step explanation:

That is so because 1/3 is *not exactly equal to* 0.333333

0.333333 is an approximation of 1/3 which is correct to 6 decimal places.

So 0.333333 x 3 = 0.999999 which is approximately equal to 1.

If you want to be more accurate, you could write the fraction 1/3 everywhere and not write it in floating point form.

1/3 in floating point format will be 0.333333333…..and so on with infinite decimal places. This is because when you try to divide 1 by 3, you get a nonterminating recurring number after decimal point.

Its usually represented by a bar or dot on top of the recurring part

Ex. 1/3 = 0.3bar

(Sorry I can't get the bar on 3 by typing from keyboard)

But let's just say 0.3 bar is 0.333333…and so on to infinity.

When you multiply 0.3bar x 3 you get 0.9bar

= 0.999999….and so on to infinity.

These decimal point figures just a very great approximations of the fraction 1/3.

Hope this helps. Feel free to reply if you still have doubts.

Answer:

1,440 calories

Step-by-step explanation:

Divide 640 by 4 to get how many calories there are per scoop.

640 calories ÷ 4 scoops = 160 calories per scoop

Then, we can multiple 160 by 9 to get the calories in 9 scoops.

160 calories per scoop × 9 scoops = 1,440 calories per 9 scoops

Answer:

1,440‬

Step-by-step explanation:

The area of the square sandbox is 1,296 square inches

The area of a square is the measure of the space or surface occupied by it. It is equal to the product of the length of its two sides. Since the area of a square is the product of its two sides, the unit of the area is given in square units.

Area of a square = Side × Side

                            =  [tex]Side ^{2}[/tex]

According to the question

Side of a square sandbox =  36 inches

Therefore,

The area of the square sandbox =  [tex]Side ^{2}[/tex]

                                                      =  [tex](36)^{2}[/tex]

                                                      =  1,296 square inches

Hence, the area of the square sandbox is 1,296 square inches

Answer:

SO WE KNOW THE RADIUS OF EACH SEMI CIRCLE IS 45. SO NOW :

YOU ARE GOING TO ADD THE AREA OF BOTH HALF CIRCLES TO THE AREA OF THE RECTANGLE.

= 26,217FT SQ.

Answer:

C, 19858.5 [tex]ft^2[/tex]

Step-by-step explanation:

Imagine that these are two semi-circles on either side of a rectangle

the diameter of the semi circle is 90, and the radius is half of the diameter.

this means the radius is 45 (for both circles)

so now lets apply that to the area of a full circle, [tex]\pi r^2[/tex]

replace r with the radius [tex]\pi 45^2[/tex]

using 3.14 as pi, your answer should be 6358.5

but now remember that his is the area of a full circle, not a semi circle, so we must divide by 2 to get the semi circle area, which would then be 3179.25

since there's two semi circles, you would multiply this by two and now you're back to 6358.5

if that was confusing you can think of it as a full circle split into two parts on either side of the rectangle rather than two semicircles, so the two split pieces would add together to make the area of a full circle

now calculate the area of the rectangle, which is length times width

150 * 90 = 13500

so add the area of the rectangle to the area of the two semicircles and the answer is 19,858.5 :)
