Answer:

i hope my answer help you:))

Step-by-step explanation:

{1st question}

b=3b-18=12

=3b=12+18

=3b=30 ( divided by 3)

then b=10

{2nd question}

d = -42-7d=49

=-7d=49+42

=-7d=91 ( divided by -7)

then d= -13

Answer: Here you go hope this helps

If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.

Slope is = (60-70)/(25-20) = -2

Using the two-point slope form, y – y1 = m(x – x1)

               y – 70 = -2(x – 20)

               y – 70 = -2x + 40

               y = -2x + 110

Step-by-step explanation:

The associate that best describes the scatter plot is the Negative association.

An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:

Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.

Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.

Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line or near to it.

Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.

If we plot the graph of the data points we will see that the trend of the data is negative, therefore, the value of one variable is decreasing with an increase in the value of another.

Hence, the associate that best describes the scatter plot is the Negative association.

C that is 12/25.

others are × by 3

Answer:

12/25 (answer C)

Step-by-step explanation:

as each of the other choices equal to 2/5 after simplification

6/15 (divide 3) = 2/5

18/45 (divide 3) = 6/15 (divide 3) = 2/5

Answer:

1) 04.4750

Step-by-step explanation:

The most obvious reason would be that if you put in 3.58 x 1.25 into a calculator the answer u get is 4.4750.

If you want a more technical explanation though, you can say that the combined number of decimal places in the multiplicand and the multiplier is 4, so the product will also have 4 decimal places.

3.58 = two decimal places

1.24 = 2 decimal places

in total, they have 4 decimal places. for the product to have 4 decimal places too you'd count from right to left 4 places, and that's where you'd put the decimal. Hope this helps!

Answer:

465 in²

Step-by-step explanation:

square area: A = lw

triangle area: A = [tex]\frac{1}{2}[/tex] lw (or base x height)

[tex]A_{square}[/tex] = (15)(15) = 225

[tex]A_{triangle}[/tex] = [tex]\frac{1}{2}[/tex] (8)(15) = 60

There is one square and 4 triangles so...

225 + 4(60) = 465 in²

Answer:

x (11 unit) is the longest side

Step-by-step explanation:

Given:

Sides;

7, x, and x−1

Perimeter = 28

Find:

Longest side

Computation:

Perimeter = sum of all sides

So,

7 + x + (x -1) = 28

2x + 6 = 28

x = 11

So,

x -1 = 11 - 1 = 10 unit

x (11 unit) is the longest side

Answer:

1. 45

2. 105

3. 95

4. 85

Step-by-step explanation:

For problems 1 and 4:

Consecutive angles are supplementary in a parallelogram, which means they equal 180.

180 - 135 = 45

180 - 95 = 85

For problems 2 and 3:

Opposite angles are congruent or equal each other in a parallelogram,

First Answer:

x = 12

First Step-by-step explanation:

12 + x = -3(4 - x)

12 + x = -12 + 3x

- x - x

—————————

12 = -12 + 2x

+ 12 + 12

—————————

24 = 2x

24/2 = 2x/2

12 = x

Second Answer:

No solution

Second Step-by-step explanation:

Answer:

AB ≈ 7.0

Step-by-step explanation:

Using the sine ratio in the right triangle

sin61° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{8}[/tex] ( multiply both sides by 8 )

8 × sin61° = AB , then

AB ≈ 7.0 ( to the nearest tenth )

Answer:

80%

Step-by-step explanation:

original: 1

Increase 25%: 1.25  if this number becomes 1

1 : 1.25 = x : 1

x = 1 / 1.25 = 0.8   (80%)

check: 0.8 x 1.25 = 1

Answer:

ST=8.8

SR=15.5

Step-by-step explanation:

ST is the difference between S and T.

that would be 16.3-7.5=8.8

similarly RT is the difference between S and R

That would be 7.5-(-8)=15.5.

Answer:

ST = 8.8

SR = 15.5

Step-by-step explanation:

As the question demonstrates, they're looking for the measure of ST - which means the distance from S to T.

Now to get ST you'll have to subtract the values given on the number line.

T = 16.3

S = 7.5

16.3 - 7.5 = 8.8

ST = 8.8

Moving on with SR, we have the following. We use the same method of differentiation.

S = 7.5

R = -8

7.5 - (-8) = 15.5

SR = 15.5

Answer:

56 degrees

Step-by-step explanation:

a straight line is 180 degrees and the angle given is 124 degrees. you just want to subtract 124 from 180

180-124=56

Answer:

y = 56°

Step-by-step explanation:

y and 124 are adjacent angles and supplementary, sum to 180° , then

y + 124° = 180° ( subtract 124° from both sides )

y = 56°
