Answer:

as a decimal,, you just devide 3/8 then multiply by 100 it results to

37.5

Answer:

Step-by-step explanation:

x= number of fives

y= number of fifties

x+y=98

5x+50y=2605

Solving through elimination...

5x+5y=490

(5x+50y)-(5x+5y)=2605-490

45y=2115

y= 47

x+47=98

x=51

Which means he has 51 fives and 47 fifties

Answer:

A = 372 m²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₁ the parallel bases

Here h = 12, b₁ = 40 and b₂ = 22 , then

A = [tex]\frac{1}{2}[/tex] × 12 × (40 + 22) = 6 × 62 = 372 m²

Answer:

Since a and b are parallel

Step-by-step explanation:

2x+27=3x - 27

collect the like terms

3x-2x=27+27

x=54

PLS MARK BRAINLIEST

Answer:

x = 54

Step-by-step explanation:

If the lines are treated as parallel , then

(3x - 27) and (2x + 27) are alternate exterior angles and congruent, so

3x - 27 = 2x + 27 ( subtract 2x from both sides )

x - 27 = 27 ( add 27 to both sides )

x = 54

For a and b to be parallel then x = 54

Answer:

that's an angle bisector my man

Corresponding Angle is the answer

She can have at least 3 and at most 6 dog treats in a day

River can have - n = 10/y number of treats to remain in her calorie range, where the calorie range is [y] calories.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following problem -

River has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range.

Assume the calorie range to be [y] calories and assume she can have [n] number of treats. We can write the linear function as -

10n = y

OR

y = 10n

This this the equation of the straight line. She can have -

n = 10/y

number of treats to remain in her calorie range.

Therefore, River can have - n = 10/y number of treats to remain in her calorie range.

Answer:

because of them is bigger than the other one so that means its differ but it has the same length

Step-by-step explanation:

x = most popular

y = second most popular

x+y=49652

x=y+6786

Substitute into the first equation

(y+6786)+y=49652

2y=49652-6786

2y=42866

y=21433

x=21433+6786=28219(answer)

Answer: 75% increase

Step-by-step explanation:

First, you subtract the two numbers to find out how much increased.

483-276= 207

Divide by original number

207/276= [tex]\frac{3}4}[/tex]

Multiply by 100

[tex]\frac{3}{4}*100=[/tex] 75% increase

Answer:

C ≅ 69.08

a= 380.1 square inches

Step-by-step explanation:

Answer:

The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8

The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2

You can check your answer by plugging in your answer to the variable and making sure both side equal each other

Step-by-step explanation:

The first one: the 5 should be - from both side so you get k=-8

The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2

Remember you always want to get the variables by themselves.

Sorry that was a lot. Hope it helps!

Answer:

y = - 1/2x + 7

Step-by-step explanation:

Slope = (-4 - - 1)/(1 - - 5) = -3/6 = -1/2

Point: (8,3)

b = 3 - (-1/2)(8)

= 3 + 4 = 7
