4(2x - 5) = 5x -20 +3x

2 answers:

6 0

Firstly, you have yo multiply out the first bracket by multiplying (2x - 5) by 4. The equation would then look like:

8x - 20 = 5x - 20 + 3x

Then you have to put normal numbers on one side and x-terms on the other. It would look like:

-20 + 20 = 5x + 3x - 8x

Then you should solve the additions and subtractions

0 = 0x

Since ANY number multiplied by 0 is zero, your equation has infinite solutions.

Answer:

All real numbers

Step-by-step explanation:

Distribute the 4 on the left side

4(2x-5)=5x-20+3x

8x-20=5x-20+3x

Combine like terms on the right side

8x-20=8x-20

All real numbers are solutions, because both sides are equal

Hope this helps! :)

Rosemary walks each week for exercise. Let d represent the distance walked and h represent the number of hours spent walking.

nadya68 [22]

Ok last week she walked 18/6 which equals 3 and 3 is less than 2.5. 2.5h is really just that times how many hours.D is the amount of miles.So,the awnser is going to be b or d.But we dont know what d is in d=2,5h so we have to asume that b is the awnser

How do you write 19,830 in scientific notation? _____× 10^_____

pshichka [43]

Answer:

1.983(10⁴)

Step-by-step explanation:

Since we need to have ones and decimals as proper scientific notation, we have 1.983. Since we need the value of 19830, we need to move the decimal place 4 places to the right, so our exponent is 4.

James states that quadrilateral

mr_godi [17]

Using the distance formula,

$AD=\sqrt{(-1-3)^{2}+(-3-(-4))^{2}}=\sqrt{17}\\\\BC=\sqrt{(5-9)^{2}+(1-0)^{2}}=\sqrt{17} \\\\\therefore \overline{AD} \cong \overline{BC}$

$AB=\sqrt{(-1-5)^{2}+(-3-1)^{2}}=\sqrt{52}=2\sqrt{13}\\\\CD=\sqrt{(9-3)^{2}+(0-(-4))^{2}}=\sqrt{52}=2\sqrt{13}\\\\\therefore \overline{AB} \cong \overline{CD}$

Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.

Question 1 of 10 Jerry drew AJKL and AMNP so that K = ZN, ZLE ZP, JK = 6, and MN = 18. Are AJKL and AMNP similar? If so, identif

butalik [34]

Answer:

This is the answer I got

Step-by-step explanation:

JK / KL = MN / NP 6 / 4 = 18 / 12

Now u cross multiply. if both numbers are equal, they are similar. In this case, they are similar. 6 x 12 = 4 x 18

72 = 72

though the two corresponding sides of the triangles mentioned are proportional (proportionality being 1:3 ) but they need not be similar

for similarity either the third corresponding sides must be proportional or the included angle between the two proportional sides must be equal
