PLS help I will give brainliest​

Answer:

can I get a better explanation and I'll help

Answer:

Step-by-step explanation:

first distribute -5(4a-3) to get -20a +15

second -33-6a=-20a+15 and add 20 to both sides to get -33+14a=15

third add 33 to both sides to get 14a=48

fourth divide 14 on both sides to get a = 3.43 (rounded to nearest hundredth)

Answer:

3x+(8x+15=180

3x+8x+15)=180

11x+15=180

11=180-15

11x=165

x=165/11

x=15

Answer:

12 is the answer for this question

Answer:

x = 0.3

Step-by-step explanation:

6x + 3 + 4x = 1/2 (9 + 10x)

=> 10x + 3 = 1/2 *9 + 5x

=> 5x + 3 = 9 / 2

=> 5x = 9 / 2 -3

=> 5x = (9 - 6) / 2

=> 5x = 3 / 2

=> x = 3 / 10

=> x = 0.3

Hope it helps :)

Answer:

X does not equal to -5,-2,-4

Step-by-step explanation:

Factor out the denominators and use inequality.

X+5=0 -> X=-5

X^2+6X+8=(X+2)(X+4)

X+2=0 ->X=-2

X+4=0 -> X=-4

Interval Notation:(−∞,−5)∪(−5,−4)∪(−4,−2)∪(−2,∞)(-∞,-5)∪(-5,-4)∪(-4,-2)∪(-2,∞)

Answer:

3 meters

Step-by-step explanation:

Given the scale drawing :

2m : 1m

Length of living room in real life = 6 m long

2 meter = 1 meter

Real life = scale drawing

If length = 6 meter long ;

using cross multiplication :

2 meter = 1 meter

6 meter = x

2x = 6

x = 6/2

x = 3 meter

Length of living room in drawing = 3 meters

Answer:

[tex]\sqrt{\left(x^2-y^2\right)^2+\left(2xy\right)^2}[/tex]

Step-by-step explanation:

Hypotenuse of a right triangle can be found using the Pythagorean theorem which states that both legs squared and added is equal to the hypotenuse squared. In other words, if A and B are legs and C is the hypotenuse:

[tex]C=\sqrt{A^2+B^2}[/tex]

We are told that one of the legs is [tex]x^2-y^2[/tex] and the other is [tex]2xy[/tex] so we get [tex]\sqrt{\left(x^2-y^2\right)^2+\left(2xy\right)^2}[/tex] when we substitute the legs into the formula presented above.

Answer:

A≈276.99in²

Step-by-step explanation:

A=5

2·62·5+2·5≈276.99152in²

Answer:

8 hours 20 minutes

Step-by-step explanation:

Given that :

Time Rachel left for school = 7:45 a.m

Time she returned Home = 4:05 p.m

Time for which Rachael was gone :

4:05 p.m - 7:45 a.m

7:45 a.m to 3:45 p.m= 8 hours

3:45pm to 4:05 pm = 20 minutes

= 8 hours 20 minutes

Rachael was gone for 8 hours 20 minutes

Answer:

x=7

Step-by-step explanation:

3x-30=-9

3x=21

x=7

hope this helped! have a Blessed day!

3(x-10) =-9

3x - 30 = - 9

3x - 30+30= - 9+30

3x =21

X = 21/3.

X= 7

Answer:

The simplified answer is 8m+3.

Step-by-step explanation:

3(2m+1)+5m

(6m+3)+5m

8m+3

Answer:

11m + 3

Step-by-step explanation:

First you distribute:

3 ( 2 + 1 )  +  5

6m + 3 + 5m

Next, you combine like terms:

6m + 5m + 3 = 11m + 3

Answer:

45 bags

Step-by-step explanation:

Cost of a dozen eggs = 2

A bag of grain = 5

Let :

dozens of eggs sold = x

Bag of grains sold = 5x

Total sales worth = 243

Quantity sold * price

2* x + 5 * 5x

2x + 25x = 243

27x = 243

x = 243 / 27

x = 9

Bags of grains sold = 5x = 9*5 = 45 bags

Answer:

640.46

Step-by-step explanation:

u find 1.1% of 620 then multiply by 3. and then add 620

Answer:

x=-2

Step-by-step explanation:

x-27 = 7x -15

subtract x from both sides

-27=6x-15

add 15 to both sides

-12=6x

divide both sides by 6

-2=x

x=-2

Answer:

x=-2

Step-by-step explanation:

x-27=7x-15(move variable left hand side /change sign)

x-7x-27=-15

x-7x=-15+27

-6x=-15+27

-6x=12

x=-2

Answer:

  14.09 square units

Step-by-step explanation:

The desired area is the area of the full circle, multiplied by the fraction that is shaded. That fraction is the ratio of the sector central angle to the central angle for a whole circle: 42°/360°.

  A = πr²(d/360)

  A = 3.14159(6.2²)(42/360) ≈ 14.09

The area of the shaded sector is about 14.09 square units.

Step-by-step explanation:

h

lol, easy 00 times 60000 is 18,000,000

Answer:

The radius of the circle=

3/2

1.5

Area of circle= Pi x radius^2

3.14 x 1.5^2

=7.06m^2

Since it's a semi circle

7.06/2

=3.53m^2

Answer:

365 in^2

Step-by-step explanation:

15 - (5+3) = 7 which is the side of the rectangle.

7*20 = 140 is the area of the top rectangle

15*15 = 225 is the area of the bottom square

365 is the total area

Answer:

18 and 162

Step-by-step explanation:

Answer: 6

Step-by-step explanation:

Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:

Shorter leg² = 10² - 8²

Shorter leg² = 100 - 64

Shorter leg² = 36

Shorter leg = ✓36

Shorter leg = 6

Answer:

The answer would be 45.

Step-by-step explanation:

5*9=45

Answer:

45

Step-by-step explanation:

First we count how many people he split it between which is 5 and we have to remember the key word here is equal so if he was left with 9 then everybody else did as well. so we multiply 5 times 9 which is 45

Answer:

5

Step-by-step explanation:

Because if you divide them all you see that in 5 you don't get a whole number
