pls someone help me with this, and fast pls

Answer:

x = 4

Step-by-step explanation:

DE / XY = EF / YZ

5 / 10 = 2x-1 / 14

cross-multiply:

10(2x-1) = 14(5)

20x - 10 = 70

20x = 80

x = 4

The ratio of their corresponding side will remain constant. Then the value of x is 4.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The two triangles are ΔDEF and ΔXYZ.

It is given that the ΔDEF and ΔXYZ are similar.

Then the ratio of their corresponding side will remain constant. That is

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]

From the first two, we have

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]

On simplifying, we have the value of x

x = 4

Answer:

76-25= 51

Step-by-step explanation:

Answer:

A. 51

Step-by-step explanation:

Subtract 25 from each side to isolate the variable

it would look like this:

x + 25 = 76

I GOTCHU

Step-by-step explanation:

step 1. wow! 670° I think you mean 67°

step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle

step 3. x + 102 + 67 = 180

step 4. x + 169 = 180

step 5. x = 11°.

Answer:

339.3 cubic inches

Step-by-step explanation:

SA (cyl) = 2πr² + 2πrh

SA = 2(3²)π + 2(3)(15)π

SA = 18π + 90π

SA = 108π

SA ≈ 339.3 in³

Given:

The graph of a system of inequalities.

To find:

The ordered pair which is a solution to the graphed inequality.

Solution:

The boundary lines are:

[tex]x-2y=4[/tex]

[tex]2x-y=4[/tex]

From the given graph it is clear that only point (3,1) lies in the shaded region.

Points (2,-1) and (4,0) lie on the boundary line [tex]x-2y=4[/tex] but the boundary line is dotted. It means the points on the line are not in the solution set.

point (0,-1) does not belong to the shaded region.

Therefore, the correct option is A.

Answer:

Santosh purchased 4 new and 4 used DVDs.

Step-by-step explanation:

From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:

15x+5y=80, where:

x refers to the number of new DVDs

y refers to the number of used DVDs

Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:

15x+5x=80

20x=80

x=80/20

x=4

According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Answer:

How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double ((1.107.3 = 2). The Rule of 72 is reasonably accurate for low rates of return.

Step-by-step explanation:

For example, if you invest $10,000 at 10 percent compound interest, then the “Rule of 72” states that in 7.2 years you will have $20,000. You divide 72 by 10 percent to get the time it takes for your money to double. The “Rule of 72” is a rule of thumb that gives approximate results

Answer:

x=12 y=6  m(ABC)=102  m(BCD)=78 m(DAB)=78

Step-by-step explanation:

alright mate so lets start with the properties of parallelogram:

(there are more but we will use those here)

m(BCD) is opposite angle for m(DAB) so those equations should be equal each other and this will give us a hint

[tex]6x+y=4x+5y\\2x=4y\\x=2y[/tex]            i just changed the places of x to be in one place and                                                                                                  s                                     same for y then divided both sides by 2

m(ABC) is adjacent to m(BCD) so

[tex](7x+3y)+(4x+5y)=180[/tex]  add x to x and y to y it will be

[tex]11x+8y=180\\[/tex]  

replace x with 2y so 11x will be 22y

[tex]22y+8y=180\\30y=180\\y=6[/tex]          added the y to y and then divided both sides by 30

[tex]x=2y \\x=2*6=12[/tex]

now we got x and y

then lets start to substitute every x and y in the equations

    3.[tex]6x+y\\6*12+6=78[/tex]

now we got everthing hope i helped you sorry also for being late it toook alot to type it so you can understand

Step-by-step explanation:

Total amount of lettuce = x pounds

Mrs. Tirado picked 5/6 pounds of lettuce from her garden.

5 / 6 * Total amount = 5/6 x

Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado.

Mrs. Rampulla = 2/3 (Mrs. Tirado) = 2/3 (5/6 x)

Mrs. Rampulla = 5/9 x

How much lettuce did they pick altogether?

Mrs. Rampulla + Mrs. Tirado

5/9 x  + 5/6 x

(25/18) x pounds
