B 40
C 50
D60

Answer:

Unit rate = 1.25 inches per yard

Length of fence B on the blueprint = 5 inches

Step-by-step explanation:

We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.

This means it's 1.2 yards long but 1.5 inches on the blueprint.

Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard

fence B is 4 yards long.

Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.

Answer:

i would say it is GOOD JOB

Step-by-step explanation:

Answer:

y = 3x+1

Step-by-step explanation:

Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:

7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.

we now can make the first part of the equation:

y = 3x + b

Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).

-5 = 3x-2 + b

you get:

-5 = -6+b

which is equal to:

b = 1

So, putting b back in the equation, you get:

y = 3x+1

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

find the distance between the two points and divide that by 3 first,

then you estimate the point that is from point A with that 1/3 distance

The coordinate of point C such that point C on AB that is 1/3 the distance from point A to point B is (-3,-2) so option (C) will be correct.

A pair of numbers is used to express a point's position on a coordinate plane using the horizontal and vertical distinctions from the two reference axes. usually represented by pairs of x-values and y-values (x,y).

Coordinate a point with intercept m: n and bounded by coordinate (x₁, y₁) and (x₂, y₂) is given by

x = [m(x₂) + n(x₁)]/(m + n)

y = [m(y₂) + n(y₁)]/(m + n)

Here m = 1/3 and n = (1-1/3) = 2/3

And coordinates A(–7, –6) and B(5, 6).

So,

x = [ 1/3(5) + 2/3(-7) ]/ 1

x = -3

And,

y =  [ 1/3(6) + 2/3(-6) ]/ 1

y = -2

So (-3,-2) will be the coordinate of point C.

Hence "The coordinate of point C is (-3,-2).

Answer:

-3

Step-by-step explanation:

7x+9=5x+3

2x+9=3

2x=-6

x=-3

Answer:

Step-by-step explanation:

7x +9 = 5x +3

combine like terms

7x - 5x = 3 - 9

2x = -6

x = -6/2

x = -3

proof:

7x +9 = 5x +3

7(-3) +9 = 5(-3) +3

Answer:

3600

Step-by-step explanation:

lcm stands for "lowest common multiple"

the lcm is 3600 when done with the prime factorization process

Answer:

3600

Step-by-step explanation:

Express each number as a product of its prime factors, that is

36 = 2² × 3²

75 = 3 × 5²

80 = [tex]2^{4}[/tex] + 5

Now multiply each factor the greatest number of times it occurs in each of the 3 numbers.

2 → 4 times (that is [tex]2^{4}[/tex] )

3 → twice (3² )

5 → twice (5² )

Thus

LCM = [tex]2^{4}[/tex] × 3² × 5² = 16 × 9 × 25 = 3600

Answer:

$513.75

Step-by-step explanation:

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week:

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

My answer is in the equation

Step-by-step explanation:

where m is the slope and b is the y-intercept. Subtract x from both sides of the equation. Multiply both sides by −1

Answer:

p=228/5

Step-by-step explanation:

2/3p-7=1/4p+12

12(2/3p-7)=12(1/4p+12)

8p-84=3p+144

5p-84=144

5p=228

p=228/5

Check:

2/3(228/5)-7=1/4(228/5)+12

30.4-7=11.4+12

23.4=23.4

The answer is:

Answer:

C. -1 1/4

Step-by-step explanation:

First, we substitute -5 for x.

[tex]f(-5)=\frac{1}{4} *-5[/tex]

Then, we evaluate.

[tex]f(-5)=\frac{1}{4} *-5=\frac{-5}{4} =-1\frac{1}{4}[/tex]

Answer:

Let x be the number of hours for 1.74 miles

5.3 miles         3.2 hours

1.74 miles        x

When you cross multiply the above numbers you get the equation:

5.3x = 5.568

x = 5.568/5.3

x = 1.05

Therefore it takes 1.05 hours to walk 1.74 miles.

Answer:   x = 6

Step-by-step explanation:

Angles 1 and 8 are alternate exterior angles, so they are equal.

so you can create an equation to solve for x

12x−20 = 2x+40  Subtract 2x from both sides. Add 20 to both sides

10x = 60

x = 6

if you need the  m∠1, Substitute 6 for x.  (2x+40)°  2(6) +40= 12+40 m∠1= 52°

m∠8=(12x−20)°   12(6) - 20 = 72-20  m∠8 = 52°
