Answer:

Answer: <em>4a - 5 = 10 - a </em>

Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) </em>

Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) <=> 5a = 15 ( a đi 1 mình nghĩa là 1a) </em>

Answer: <em>4a - 5 = 10 - a <=> 4a + a = 10 + 5 ( chuyển vế đổi dấu, số 1 vế biến 1 vế) <=> 5a = 15 ( a đi 1 mình nghĩa là 1a) <=> a = 3 ( lấy 15 : 3 = 5 )</em>

Solve 15x+3y=9,10x+7y=-4
TiliK225 [7]

Answer:

x = 1, y = -2

Step-by-step explanation:

15x + 3y = 9 (1)

10x + 7y = -4 (2)

3 × (2) - 2 × (1)

3 × (2)

30x + 21y = -12 (3)

2 × (1)

30x + 6y = 18 (4)

(3) - (4)

15y = -30

y = -30 / 15

y = -2

sub y = -2 into (1)

15x + 3y = 9

15x + (3 × -2) = 9

15x - 6 = 9

15x = 9 + 6

15x = 15

x = 15 / 15

x = 1

The area of the square hole is 8 square centimeters. The volume of a cube shaped block is 64 cubic centimeters. Which edge lengt
damaskus [11]

<u> case a)</u> The area of the square hole is 8 square centimeters

we know that

the area of a square is equal to

A=b^{2}

where

b is the length side of the square

in this problem we have

A=8\ cm^{2}

<u>Find the length side b</u>

b^{2} = 8 \\b= \sqrt{8} \ cm\\b= 2\sqrt{2} \ cm

<u>the answer Part a) is</u>

the length side of the square is 2\sqrt{2} \ cm

Part b) The volume of a cube shaped block is 64 cubic centimeters

we know that

the volume of a cube is equal to

V=b^{3}

where

b is the length side of the cube

in this problem we have

V=64\ cm^{3}

<u>Find the length side b</u>

b^{3} = 64 \\b= \sqrt[3]{64} \\b= 4\ cm

therefore

<u>the answer Part b) is</u>

the length side of the cube is 4\ cm
