Answer:

a=12 b=9

Step-by-step explanation:

u can substitute 3/4a in for b in a+b=12 since it is equal to b, giving you

a+3/4a=21

a=4/4a

4/4a+3/4a=21

7/4a=21

4/7(7/4a=21)

a=12

plug in 12 for a in either equation

b=3/4*12

b=9

(21=12+b) -12

9=b

Answer:

Step-by-step explanation:

Answer: The last option has no solution.

1. ) The solution is 1/2

2) The solution is  -17/27

3) The solution is infinitely many solutions.

4) There is no solution because the answer solved and simplified comes out to be 17= -10; this is impossible so there is no solution

Answer:

5(2.2y + 3.4) = 5(y - 2) + 6y

Step-by-step explanation:

In order to answer this question, one must solve each of the equations until one has reached a conclusion that the parameter (y) has no solution in the given circumstance.

Equation 1

13y + 2 - 2y = 10y + 3 - y

Simplify, combine like terms;

11y + 2 = 9y + 3

Inverse operations,

11y + 2 = 9y + 3

-9y

2y + 2 = 3

-2

2y = 1

/2

y = 0.5

Equation 2

9(3y + 7) - 2 = 3(-9y + 9)

Distribute, multiply every term inside the parenthesis by the term outside of it;

(9)(3y) + (9)(7) - 2 = (3)(-9y) + (3)(9)

Simplify,

27y + 63 - 2 = -27y + 27

27y + 61 = -27y + 27

Inverse operations,

27y + 61 = -27y + 27

+27y

54y + 61 = 27

-61

54y = 34

/54

y = [tex]\frac{17}{27}[/tex]

Equation 3

32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1

Simplify, combine like terms;

34.5y - 5.1 = 34.5y - 51

As one can see, this equation is an identity, meaning that any value can be substituted into the parameter (y) to produce a true result.

Equation 4

5(2.2y + 3.4) = 5(y - 2) + 6y

Distribute, multiply every term in the parenthesis by the term outside of it;

(5)(2.2y) + (5)(3.4) = (5)(y) + (5)(-2) + 6y

Simplify,

11y + 17 = 5y - 10 + 6y

11y + 17 = 11y - 10

Inverse operations,

11y + 17 = 11y - 10

-11y

17 = -10

One can see that this equation produces a false result since it is common knowledge that (17) cannot equal (-10). Therefore, this equation has no solutions.

Answer:

81 un²

Step-by-step explanation:

9 · 7 = 63 un²

(b · h) ÷ 2

Answer:

18.75=p

s=14.06

b=2.34

Step-by-step explanation:

37.75=b+s+p

-4

33.75=b+s+p

s=3/4p

b=1/6s

33.75=1/6(3/4p)+3/4p+p

33.75=3/20p+3/4p+p

(33.75=18/20p+p)20

675=18p+p)/18

37.50=2p)/2

18.75=p

s=3/4p

3/4(18.75)

s=14.06

b=1/6s

1/6(14.06)

b=2.34

37.75-4=18.75+14.06+2.34=35.15

im missing 50 cents somewhere its wrong but close i think sorry

The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.

Total = $37.75

Amount left = $4.00

let

37.75 = p + b + s + 4

37.75 - 4 = p + 1/6s + 3/4p

33.75 = 1/6s + 1 3/4p

33.75 = 1/6(3/4p) + 1 3/4p

33.75 = 3/24p + 7/4p

33.75 = 3+42 / 24p

33.75 = 45/24p

p = 33.75 ÷ 45/24

= 33.75 × 24/45

= 810/45

p = $18

substitute into

s = 3/4p

= 3/4 × 18

= 54/4

s = $13.5

b = 1/6s

b = 1/6 × 13.5

b = 13.5/6

b = $2.25

Answer:

The radious would be 2.26

Step-by-step explanation:

Answer:

r = 2.26 ft

Step-by-step explanation:

v = πr²h

80 = πr²(5)

Divide both sides by

16 = πr²

Divide both sides by π (using 3.14 )

5.0955414013 = r²

Take the square root of both sides

r = 2.2573305919

Answer:

57º

Step-by-step explanation:

A triangle equals 180º so to find x, just subtract the other angles from 180

180 - 39 - 84 = 57

Step-by-step explanation:

x+39+84=180 (being sum of angle of triangle is 180)

x+123=180

x=57

Answer:

Component Form: v = <-1,6>

Magnitude of v: ||v|| = √37

Direction of v: θv = 100° (to the nearest degree)

Step-by-step explanation:

Component Form: v = <(5-6),(3-(-3))> = <-1,6>

Magnitude of v: ||v|| = √[(-1)²+(6)²] = √(1+36) = √37

Direction of v: α = tan⁻¹|6/-1| = tan⁻¹|-6| = tan⁻¹(6) = 80.53° which is your reference angle, but to verify that the angle is in the second quadrant, you'll need to do θv = 180° - 80.53° = 99.47°, therefore your direction angle is θv=100° to the nearest degree.

Answer:

y= -3/2X + 2

Step-by-step explanation:

we get the gradient by picking any two points from the graph( it a linear graph)

using the point:

(x,y)= (-2,5) , (4,-4)

using M= (y2-y1)/x2-x1)

we get our gradient to be -9/6 which is

-3/2

using the equation of a straight line graph which is

y-y1=m(x-x1) and the point (4,-4)

we get

y-(-4)=-3/2(x-4)

----> y+4= -3/2x + 6

make y subject of the formula to take the form

y=mx+c

we get :

y=-3/2x + 2

Answer: the answer is: 54857510

Step-by-step explanation:

What i had just did was i just broke the equation into 2 parts: so i did first (4 + 78908 + 54732927 - 7) which gave me 54811832. Then i did the next part which was adding 45678 in the mix ( 54811832 + 45678 = 54857510) So, the number from which you are left with is 54857510.

((TIP: Next time when you see problems like this, break them down into smaller equations so it will be much easier for you to solve, and its much more quicker and less harsh on your brain  rather then just trying to do in all in one shot))
