<h2><u>Question</u><u>:</u><u>-</u></h2>

Solve the following:

\\  \sf \: a) \:  \:  \frac{a}{5}  + 3 = 8

\\  \sf \: b) \:  \:  \frac{3b}{7}  - 1 = 5

<h2><u>S</u><u>olution:</u><u>-</u></h2>

Solving question a) :

\\  \sf \frac{a}{5 }  + 3 = 8

\\  \sf \mapsto \frac{a + 15}{5}  = 8

\\  \sf \mapsto \: a + 15 = 8 \times 5

\\  \sf \mapsto \: a = 40 - 15

\\  \sf \mapsto \: a = 25

\\  \sf \therefore \: a = 25

Solving question b) :

\\  \sf \frac{3b}{7}  - 1 = 5

\\  \sf \mapsto \:  \frac{3b - 7}{7} = 5

\\  \sf \mapsto3b - 7 = 5 \times 7

\\  \sf \mapsto3b = 35 + 7

\\   \sf \mapsto \: b  =  \frac{42}{3}

\\ \sf \mapsto \: b = 14

\\  \sf \therefore \: b = 14

<h2><u>Answer</u><u>:</u><u>-</u></h2>

a = 25

b = 14

The ratio is 91/120 because 91 is only divisible by 1, 7, 13, 91 and 120 is not divisible by 7, 13, or 91 so you cannot reduce this ratio

The formula s= √SA/6 gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a cube w
amm1812
Surface area of cube = 6 * (side)^2
side^2 = surface area / 6
side = sqrt (surface area / 6)

For the cube with area 1200 square inches:
side = sqrt(surface area / 6)
side = sqrt(1200 / 6) 
side = 14.1421 inches

For the cube with area 768 square inches:
side = sqrt(surface area / 6) 
side = sqrt(768 / 6) 
side = 11.3137 inches

difference between the two lengths = 14.1421 - 11.3137 = 2.8284 inches

Based on the above calculations, the side of the cube with surface area 1200 square inches is  2.8284  inches longer than the side of the cube with surface area 768 square inches

Kryger [21]

Answer:

$21,000

Step-by-step explanation:

Solve the following fraction problem and choose the correct alternative: Jaime buys a property for $ 84,000 and after one year sells it earning 1/4 of the purchase price. How much was the profit? *

The amount of profit is calculated as

1/4 of the purchase price

Purchase price = $84,000

= 1/4 of $84,000

= 1/4 × $84,000

= $21,000

Therefore, the amount of the profit = $21,000
