Answer:

- [tex]\frac{12}{20}[/tex]

Step-by-step explanation:

To obtain a denominator of 20 requires the numerator and denominator to be multiplied by 4 , that is

- [tex]\frac{3}{5}[/tex] = - [tex]\frac{3(4)}{5(4)}[/tex] = - [tex]\frac{12}{20}[/tex]

Answer:

729x/64

Step-by-step explanation:

Expression: x *(3/2)⁶

Using order of operations (PEMDAS), we solve for the exponent first. So, 3^6 is 729 and 2^6 is 64. Multiple everything together to get 729x/64

Answer:

5)7:8=180

84:96=180

6)4:5=90

40:50=90

7)a). q=135

p=45

b).a=70

b=110

supplementary angle=sum of two angle 180°

complementary angle=sum of two angle 90°

Answer:

The two angle 7 and 8 —> 7x and 8x

Sum of two supplementary angle is 180°

7x +8x =180

15x =180

x= 180/15

x = 12°

7x =7(12)= 84°

8x = 8(12)= 96°

The angles; 84° , 96°

The two angle 4 , 5 —> 4x and 5x

Sum of two complimentary angle is 90°

4x+5x =90

9x =90

x=90/9

x=10

4x—> 4(10) = 40°

5x —> 5(10) = 50°

The angles; 40° , 50°

q= 135 ( Vertically Opposite angles)

q+p = 180

135+p=180

p=180-135

p = 45°

_______o_____o_____

a= 70° ( Alternate angles)

a+ b = 180

70 + b = 180

b =180 - 70

b = 110

So ; angle a=70° , b = 110°

The independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

In an experiment, there are two (2) main types of variables and these include:

An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and represented by x.

In this scenario, we can infer and logically deduce that the independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

Answer:

36 + 3b = 117

Step-by-step explanation:

36 is the one specialized cake he sold.

3 is the cost and b is how many it represents

117 is your total, so we piece it together.

36 + 3(b) = 117

Answer:

36 + 3b = 117

Step-by-step explanation:

.......................

Step-by-step explanation:

a) x=14°

b) x=23°

Answer:

x = 1

Step-by-step explanation:

Given

1000x = 1000 ( divide both sides by 1000 )

x = [tex]\frac{1000}{1000}[/tex] = 1

The given equation is,

→ 1000x = 1000

Let's find the required value of x,

→ 1000x = 1000

→ x = 1000/1000

→ [x = 1]

Therefore, 1 is the value of x.

Answer:

y=1/3x+7

Step-by-step explanation:

1. The given equation is y=1/3x-6 and it has to be parallel passing through (-12,3), so you just plug in the x and y values into the equation y=mx+b with 1/3 as the slope since its parallel (meaning the slope is the same for both eqts)

2. 3=1/3(-12)+b

3. 3=-4+b

4. 7=b

5. So, the equation is y=1/3x+7

64x2.3 Which would be 147.2 but then round up would get u 147

Answer:

C

Step-by-step explanation:

Answer:

c.

Step-by-step explanation:

Starting with the multiplications, first the multiply matrix A by -4, so we multiply every value in the matrix by -4 and we get

16 16 -4

-4 -16 -28

-8 -12 -12

Then we do the next multiplication which is 8 by matrix B, so once again we multiply every value in the B matrix by 8

16 72 -72

64 64 -16

32 80 8

Now that we did both multiplications, just need to sum the results, so we sum each value of matrix A with the value on the matrix B that's on the same spot

16 + 16 16 + 72 -4 + (-72)

-4 + 64 -16 + 64 -28 + (-16)

-8 + 32 -12 + 80 -12 + 8

And the final result is

32 88 -76

60 48 -44

24 68 -4

So it's option c

Answer:

22 cakes were sold.

Step-by-step explanation:

In order to solve this, add the cookies and cakes together (6+1=7) to get 7. Next, divide the cookies and cakes sold combined and divide that by the 7. 154/7=22. You sold 22 cakes and 132 cookies.

To check this answer multiply 6*22=132. Then multiply 22*1=22.

And add; 132+22=154.
