solve using elimination 3x+5y=4; -3x+y=8​

Answer:

21. Vol. = L ^ 3

or, 27000 = L ^ 3

or, cube root undefr 27000 = L

Therefore, Edge length = 30 cm

22.

a. v = l ^ 3

or, 64000 = l ^ 3

or, cube root under 64000 = L

or, l = 40 cm

Also,

surface area = 6 a ^ 2

= 6 * 40 ^ 2

= 6 * 1600

= 9600 cm ^ 2 #

Answer:

Step-by-step explanation:

400/700 = 4/7

salt: 4/7 × 14 g = 8 g

yeast: 4/7 × 7 g = 4 g

oil: 4/7 × 35 mL = 20 mL

water: 4/7 × 420 mL = 240 mL

Step-by-step explanation:

1. Given,

Side of the cube = 9 cm

Therefore, volume of the cube = side × side × side

= 9cm × 9cm × 9cm

[tex] = 729 {cm}^{3} (ans)[/tex]

2. Given,

Length of the rectangle = 4cm

Breadth of the rectangle = 3cm

Therefore, perimeter of the rectangle = 2(l+b)

= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)

3. Given,

Side of a square = 11 m

Therefore, area of the square = side × side

= 11 m × 11 m

[tex] \: = {121cm}^{2} (ans)[/tex]

4. Given,

Length of the rectangle = 14 m

Width of the rectangle = 5 m

Therefore, area of the rectangle = l × b

= 14 m × 5 m

[tex] = 70 {m}^{2} (ans)[/tex]

5. Given,

Side of the equilateral triangle = 15 cm

Therefore, perimeter of the triangle = 3 × side

= 3 × 15 cm = 45 cm (Ans)

Y=3/5x-3

Step-by-step explanation:

Answer:

y=5/3x+5

Step-by-step explanation:

1)3y-5x=15

2)3y=15+5x

3)y=5+5/3x

4)y=5/3x+5    

1) Write the equation out

2) Add 5x to both sides of the equation

3) Divide both sides of the equation by 3

4) Reorder the terms

Answer:

If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.

Step-by-step explanation:

a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

Answer:

$7,719.33

Step-by-step explanation:

$24,500 x 0.06 = $1,470

($24,500 + $1,470) x 0.06 = $1,558.20

($24,500 + $1,558.20) x 0.06 = $1,563.49

($24,500 + $1,563.49) x 0.06 = $1,563.81

($24,500 + $1,563.81) x 0.06 = $1,563.83

$1,470 + $1,558.20 + $1,563.49 + $1,563.81 + $1,563.83 = $7,719.33

Answer: x = 29

Step-by-step explanation:

both angles are the same

so:

2x = 3x-29

2x - 3x = -29

-x = -29

x = 29

Answer:

6

Step-by-step explanation:

Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.
