1x+2y=5 find four solutions

​

Both ABC and DEF are right triangles.

Because BC is congruent to EF, two of the corresponding angles of the triangle are congruent.

C is congruent to F

Answer:

7.6 x 11 = 83.6

Ignore decimal points, multiply normally.

THEN consider the numbers after the decimal point, count them then place the decimal point in your final answer from the left to the right of the many times the numbers are after the decimal point.

Answer:

x = 1

Step-by-step explanation:

Were trying to solve for x so we would say 3 1/2 - 2 1/2 and we would be left with 1. So x=1, which you then substitute into the problem to make sure it's correct so 2 1/2 + 1 = 3 1/2.

Step-by-step explanation:

79.5

5/19.3 = 19.3/p (cross Multiplication)

372.49=5p Divide 5 is 74.49 round to the nearest tenth (74.5) then plus the mans height (5) which equals 79.5

Answer:

x = 4, y = 5

Step-by-step explanation:

[tex]2x-y=3\\4x-2y=6[/tex]

so:

[tex]4x - 2y = 6\\+ 5x + 2y = 30\\9x= 36\\x=4[/tex]

Substitute this into 2x - y = 3:

[tex]8-y=3\\y = 5[/tex]

Answer: C

Step-by-step explanation:

Answer:

$4

Step-by-step explanation:

If she have $6 so 6-2=4

If buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus,  [tex]a \div b[/tex]= a divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex] )

Given that:

To find:

The amount she'd save if she buy only one such beanie baby.

Amount that she'd save = Total amount she could've spent - Total price of one beanie baby

As we know, total amount she could've spent  = $d

Also, because of 3 beanie babies cosing equal, and total cost being $d,

the cost of each beanie baby is:

$d divided in 3 equal parts =  d/3 dollars

Thus, we get:

Amount that she'd save = Total amount she could've spent - Total price of one beanie baby

Amount that she'd save = [tex]d - \dfrac{d}{3} \: \rm dollars[/tex]

We can write d = 3d/3 since dividing and multiplying a number by same non-zero number doesn't affect that number.

We do so, so that that both terms could get in fraction form with same denominator so that numerators could work directly.

[tex]d - \dfrac{d}{3} = \dfrac{3d}{3} - \dfrac{d}{3} = \dfrac{3d - d}{3} = \dfrac{2d}{3}[/tex]

Thus, if buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

Answer:

x = 20

Step-by-step explanation:

just or the record, it only 5 points, not 50

180 - 80 = 100

3x + 2x = 5x

5x = 100

divide by 5

x = 20

Plz mark as brainliest if correct! Have a nice day!!!

-Lil G

Answer:

x=25

Step-by-step explanation:

Hey There!

Those angles are supplements meaning all of them added together will equal 180

so we set up an equation

180 = 3x+2x+80 and solve for x

step 1 combine like terms

3x+2x=5x

now we have

180=5x+80

step 2 subtract 80 from each side

180-80=100

80-80 cancels out

now we have

5x=100

step 3

divide each side by 5

5/5 cancels out

100/5=25

x=25

Therefore the value of x is 25

Answer:

El perímetro del triángulo rectángulo es aproximadamente 29.627.

Step-by-step explanation:

Las coordendas de los vértices del triángulo rectángulo son [tex]A(x,y) = (1,-2)[/tex], [tex]B(x,y) = (-8,4)[/tex] y [tex]C(x,y) = (5,2)[/tex]. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:

[tex]AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}[/tex]

[tex]AB \approx 10.817[/tex]

[tex]BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}[/tex]

[tex]BC \approx 13.153[/tex]

[tex]AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}[/tex]

[tex]AC \approx 5.657[/tex]

El perímetro del triángulo ([tex]p[/tex]) es la suma de todos estos segmentos:

[tex]p = AB + BC + AC[/tex]

[tex]p \approx 29.627[/tex]

El perímetro del triángulo rectángulo es aproximadamente 29.627.

3 x 3

You are multiplying 3 by itself , so you have two 3’s.

Exponential form is the number raised to the total numbers:

Answer is 3^2

The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total outcomes = {1, 2, 3, 4, 5, 6]

Total number of outcomes = 6

Favourable outcomes = {5}

Total number of favourable outcomes = 1

Probability of rolling 5 = 1/6

The expected number of 5's would be 30×(1/6) =  5 times

Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

Step-by-step explanation:

Answer:

Margret is correct, Kevin is wrong.

Step-by-step explanation:

6^-4 can be written as (1/6)^4

By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4

Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.
