Answer:

  -1

Step-by-step explanation:

Solving the given equation for y, we have ...

  x -y = 18

  y = x - 18 . . . . . add y-18

The coefficient of x is 1. That is the slope of the given line. The desired perpendicular line will have a slope that is the negative reciprocal of this:

  m = -1/1 = -1

The slope of the perpendicular line is -1.

__

The graph shows you that a line with slope -1 is perpendicular to the given line.

Answer:

Her profit in dollars is;

d = 13c - 85

Step-by-step explanation:

Mathematically,

profit = sales - cost price

She sells at $13 per copy

so for c copies, total sales amount will be 13 * c= $13c

So the profit d in dollars will be;

d = 13c - 85

Answer:

Step-by-step explanation:

Step one:

given data

we are told that she earned $3 every 20minute for gutter cleanup

and for mow, she earns $3.6 every 20 minutes.

Step two;

1. For a 40 minutes gutter cleanup she will make

=3*40/20

=3*2

=$6

1. For a 2 hours mow she will make

2 hours is 120 minutes

=3.6*120/20

=3*6

=$18

So in total she earned 6+18= $24

it increases 3° each hour

3*2= 6

6° after 2 hours

3*3= 9

9° after 3 hours

3*6= 18

18° after 6 hours

Answer:

Jo's age = x = 8 years

Step-by-step explanation:

Let

Jo's age = x

Jo's mother, Anne's age = 4x

In four years time, Anne will be three times as old as Jo.

Jo's age =3( x + 4)

Jo's mother, Anne's age = 4x + 4

How old is Jo?

Equate Jo's age and his mother's age

3(x + 4) = 4x + 4

3x + 12 = 4x + 4

3x - 4x = 4 - 12

-x = - 8

Divide both sides by -1

x = 8

Therefore,

Jo's age = x = 8 years

The answer is 2nd one

2nd pair of triangle is congruent by ASA(angle side angle)

Answer:

2nd option is correct.

Answer:

-3

Step-by-step explanation:

Based on his weekly salary and commission, we can calculate that Mr. Randall sold goods worth $1,800.

In the formula given, sales is represented as s. To find the total sales, you can solve the equation:

300 + 0.07s = 426

0.07s = 426 - 300

s = 126 / 0.07

= $1,800

In conclusion, Mr. Randall sold $1,800 worth of goods.

Answer:

h=60

Step-by-step explanation:

The angle that is 120 degrees and the angle that is h degrees are called same side interior angles

Same side interior angles are supplementary, meaning that they add to 180 degrees

To find h we can use Measures addition postulate to find the unknown value h

h+120=180

Answer:

Mike can make 4 bows

Step-by-step explanation:

Given

[tex]1\ bow = 3\frac{1}{2}\ ft[/tex]

[tex]Ribbon = 14\ ft[/tex]

Required

Determine the number of bows he can make

To do this, we simply divide the length of the ribbon by length of 1 bow:

i.e.

[tex]Number = Ribbon/1\ bow[/tex]

[tex]Number = 14\ ft/3\frac{1}{2}\ ft[/tex]

[tex]Number = 14/3\frac{1}{2}[/tex]

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

Convert to *

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

[tex]Number = \frac{28}{7}[/tex]

[tex]Number = 4[/tex]

Hence, Mike can make 4 bows

Answer:

x = 111°

x° = 111°

(x-42)° = 69°

Step-by-step explanation:

Any polygon with *n* number of sides has an interior angle sum of (n-2) × 180°.

Therefore this right trapezoid must have an interior angle sum of 360° because

a trapezoid has 4 sides → n = 4 →

(n-2) × 180° = (4-2) × 180° = 2 × 180° = 360°

Because we are given a 90 degree angle with a set of parallel sides, the angle above that must also be a right angles well so these will total 180°.

The last two angles are given by the two expressions x°, and (x-42)°. Because we know the sum of these angles which are 360° we can create the following equation from these angles and solve!

180° + 2x - 42° = 360°

(Group the constants / numbers without a variable ; associative property of addition)

180° - 42° + 2x = 360°

(Find the total value of the constants)

138° + 2x = 360°

(subtract 138° from both sides to isolate 2x on the left side ; subtraction property of equality)

138° - 138° + 2x = 360° - 138°

(Work out the value of the constants again)

2x = 222°

(divide by 2 on both sides to cancel out the coefficient of 2 in 2x to get x by itself ; division property of equality)

2x / 2 = 222° / 2

(Simplify the two expressions)

x = 111°

_____________________

To find the measure of the x expressions, just substitute x = 111° into the expressions and simplify to find the measure!

So:

x = 111° → x° = 111°

x = 111° → (x-42)° → (111 - 42)° = (69)° →

(x-42)° = 69°

Step-by-step explanation:

3/4÷5/16

3/4×16/5

=12/5(2 2/5)

(3/4) divided by (5/16) in its simplest form is 12/5.

To divide two fractions, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by flipping the numerator and the denominator.  So, to divide (3/4) by (5/16), you can multiply (3/4) by the reciprocal of (5/16):

(3/4) ÷ (5/16) = (3/4) * (16/5)

Now, multiply the numerators and denominators:

Numerator: 3 * 16 = 48

Denominator: 4 * 5 = 20

3/4) ÷ (5/16) = 48/20

To simplify this fraction, find the greatest common divisor (GCD) of the numerator and the denominator, and then divide both by the GCD:

GCD of 48 and 20 is 4.

(48/4) ÷ (20/4) = 12/5.

Step-by-step explanation:

Answer:

Step-by-step explanation:

i know it

Answer:

et's start by defining the three consecutive integers.

.

If x represents the least of the three, then the next consecutive integer is x+1 and the

next consecutive integer is 1 more than that ... or x + 2

.

So the three consecutive integers are x, x+1, and x+2.

.

Twice the least integer is, as you correctly wrote, 2x.

.

12 more than the greatest integer is x+2 + 12 = x + 14

.

Since these two amounts must be equal, you can write:

.

2x = x + 14

.

Now you need to get rid of the x on the right side so that you end up with all the terms

containing x on one side of the equation and everything else on the other side. You can

get rid of the x on the right side by subtracting x from the right side. But if you subtract

something from the right side, you must also subtract it from the left side to keep the

equation in balance. So subtract x from both sides. When you do that, the x disappears

from the right side and the left side becomes 2x minus x which is just x.

.

So the equation is reduced to:

.

x = 14

.

If x is 14 then the next two consecutive integers are 15 and 16 ... x+1 and x+2. So the

three consecutive integers are 14, 15, and 16.

.

Check ... the least integer is 14. Twice the least integer is 28. Is 28 actually 12 more

than the greatest integer which is 16? Yes it is, so the problem checks.

.

You were on the right track, but you just needed to know the difference in the three integers

was that they were x, x+1, and x+2. Hope this helps to show you how you could work the

problem through to get the final answer.

C. Distribute 6 to eliminate the parentheses.

To solve an equation we follow BODMAS rule which stands for first solving which are inside brackets then we divide terms to each other if division is given.Then we multiply terms if multiplication is given.Next step we add terms if given.In last we do subtraction if it is in the given expression.If any of these operations are not given we just skip and do the next operation according to the BODMAS rule.

According to the given question

Charlotte wants to solve the equation 6(2x+1) – 3 = 4x – 5.

6( 2x + 1 ) - 3 = 4x - 5

12x + 6 - 3 = 4x - 5

12x + 3 = 4x - 5

12x - 4x = - 5 - 3

8x = - 8
