Which expression has a value of 39?

Answer: see below

Step-by-step explanation:

Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.

So, 1) AB/BC = AJ/JI

2.5/2.25 = AJ/1.8

AJ = 2.5* 1.8 / 2.25

AJ = 2

2) BC/CD = JI / IH

2.25/CD = 1.8/1.2

CD = 2.25 * 1.2 / 1.8

CD = 1.5

3) CD/DE = IH/HG

1.5/3.5 = 1.2 / HG

HG = 1.2 * 3.5 / 1.5

HG = 2.8

4) For GF, we should use "Pythagoras Theorem"

h² = a² + b²

GF² = 6.5² - 6²

GF² = 42.25 - 36

GF = √6.25

GF = 2.5

5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2

P = 26.55

6) Area = 1/2 * b * h

A = 1/2 * 9.65 * 10.3

A = 49.70

Answer:

600 and 3

Step-by-step explanation:

This is the same as saying x < 0.5 since 1/2 = 0.5

====================================================

Work Shown:

2(1-x) > 2x

2*1 + 2*(-x) > 2x ..... distribute

2 - 2x > 2x

2 > 2x+2x .... adding 2x to both sides

2 > 4x

4x < 2 ..... flip both sides; flip the inequality sign

x < 2/4 ..... dividing both sides by 4; see note below

x < 1/2

Note: We do not flip the inequality sign here because we are dividing both sides by a positive value. The inequality sign would only flip if you divide both sides by a negative number.

It's just the number that doesn't have a x to the side on it

Answer:

(0,-5)

(0,0.50)

Step-by-step explanation:

just put the number that doesn't have x with it in the answer spot but don't forget to do the (0,#) it's important that you do it like that so for example the problem y=4x-3 you would just put in the answer column (0,-3)

Step-by-step explanation:

[tex]11 {}^{x - 4} = 121 {}^{x} \\ 11 {?}^{x - 4} = 11 {}^{11x} \\ x - 4 = 11x \\ x - 11x = 4 \\ \\ - 10x = 4 \\ x = - 0.4[/tex]

Answer:

[tex]\frac{1}{20}[/tex] more cheese in Sarah's dish than Amyn.

Step-by-step explanation:

To find this, we need to get the two fractions, [tex]\frac{2.5}{10}[/tex] and [tex]\frac{1.6}{8}[/tex] to a common denominator. The closest one is a multiple of 4 for [tex]\frac{2.5}{10}[/tex] and a multiple of 5 for [tex]\frac{1.6}{8}[/tex] .

This makes both fractions much more comparable, and we have

[tex]\frac{10}{40}[/tex]  for Sarah's dish

[tex]\frac{8}{40}[/tex] for Amyn's dish.

Knowing Sarah has [tex]\frac{2}{40}[/tex]'s more cheese in her dish, we can still simplify, so after dividing 40 by 2, we get [tex]\frac{1}{20}[/tex], the simplest form of how much more cheese Sarah has in her dish than Amyn,

Answer: 4/10 = look below for explanation

Step-by-step explanation:

Transform 2/5 into the same demononator

= 2/5 becomes 4/10 because you've multiplied 2x2 and 5x2

which becomes 4/10 and 1/10

to solve: 4/10 - 1/10 = 3/10

Answer:

5x+32=45;x=2.6

Step-by-step explanation:

5x+17+15=45

5x+32=45

5x=13

x=2.6

Answer:

x=2.6 is required equation.

perimeter of triangle=45

sum of all sides=45

5x+17+15=45

5x=45-32

5x=13

x=13/5=2.6

Answer: 38

Step-by-step explanation:

Answer:

Perimeter= 38, EC- Area= 19.5

Step-by-step explanation:

substitute all the x's for 5. simplify each equation. H=3, Base= 13, 4x+2=22

h- 5-2=3

4(5)+2=22

base- 2(5)=3=13

then add all answers together to get 38.

multiply 13 and 3 to get 39, then divide by 2 to get 19.5 for the area.

Answer:

d

Step-by-step explanation:

school is only 5 days a week and if she walks 60 yards to the bus stop and 60 yards back from the bus stop than she walks a total of 120 yards a day

120 x 5 =600 the answers are in feet so we need to convert to feet and to do that we need to multiply by 3

600x3=1800

so she walks 1800 feet in a normal school week

Answer:

Step-by-step explanation:

The length of the rectangle is x + 9 whose width is gives as 2x.

To find the length of the rectangle, we need to express it in terms of the width.

Given:

width of the rectangle is 2x.

The formula for the area of a rectangle is

A = length × width.

As, the polynomial function for the area:

[tex]A(x) = 2x^2 + 18x[/tex]

So, set up the equation:

[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]

Substituting the given width = 2x in above equation gives

[tex]2x^2 + 18x = 2x * length[/tex]

Dividing both sides of the equation by 2x:

x + 9 = length

Therefore, the length of the rectangle is x + 9.

the answer is 2 or 2/1 hope this helps

Answer:

In fraction form, the slope is 2/1.

Or, the slope is just 2.

Step-by-step explanation:

Using the equation:

m =  

y2 - y1  /

x2 - x1

Plug in the x and y points and solve.

note: m = slope in slope intercept form, y - mx + b

y2 = 14     y1 = 18

x2 = -16     x1 = -14

14 - 18 / -16 -(-14)

-4 / -2

Simplified: -2 / -1

In fraction form, the slope is -2 / -1, or 2/1 because either way works.

Or, the slope is just 2.

Answer:

y = 3x + 4

Step-by-step explanation:

Because $4 is your base pay, it is your y-intercept. And because it is $3 per child, then that is your slope. "x" represents how many objects/people/etc. there could be.
