15 more than 3 times a number is at most 7

hammer [34]

Answer:

Let x = the number

"Fifteen more than" means addition

"Three times a number" is multiplication

"three less than" is subtraction, as is the term difference

Putting it all together, we have

7 - (15 + 3x) = (9 - 5x) - 3

-8 + 3x = 6 - 5x

-8 = 6 - 8x

-14 = -8x

14/8 = 7/4 = x

Solve using perfect square factoring patterns. x2 – 12x + 36 = 4 A. {–8, –4} B. {–2, 10} C. {4, 8} D. {10, –2}

Nataliya [291]

x2 – 12x + 36 = 4
(x - 6)^2 = 2^2

x - 6 = 2
x = 8

-(x - 6) = 2
-x + 6 = 2
-x = -4
x = 4

answer
C. {4, 8}

A board of length 7 divided by the quantity x minus 2 end of quantity meters was cut into two pieces. If one piece is 3 divided

bulgar [2K]

Answer:

Length of other board $=\frac{4x+20}{x^{2} -4}$ metres

Step-by-step explanation:

Given: Length of board = $\frac{7}{x-2}$ metres

Length of board was divided into two.

Length of one piece = $\frac{3}{x+2}$ metres

Let $l$ = length of the other board

Length of the other board = Length of board - Length of one piece

So, $l=\frac{7}{x-2}-\frac{3}{x+2}$

$l=\frac{7(x+2)-3(x-2)}{(x-2)(x+2)} \\\\l=\frac{7x+14-3x+6}{x^{2} -4} \\\\l=\frac{4x+20}{x^{2} -4}$

Thus, length of the other board $=\frac{4x+20}{x^{2} -4}$ metres

Alice's grandfather is showing Alice his apple

Amanda [17]

There are 156 rows of trees altogether.

Step-by-step explanation:

Given that for every 11 rows of Red delicious , they plant 3 rows of Royal Gala.

Thus for 1 row of Royal Gala there would be 11/3 rows of Red delicious.

Number of rows of Royal Gala=18

$corresponding\ number\ of\ Red\ delicious\ = 11/3 \times 18=11\times 6=66$

For 11 rows of red delicious,they plant 7 rows of yellow delicious.

Thus for 1 row of Red delicious,there would be 7/11 rows of yellow delicious.

For 66 rows of red delicious there would be

$7/11\times66=7\times 6=42 rows\ of\ yellow\ delicious$

For 11 rows of red delicious,they plant 5 rows of Braeburn

for 1 row of red delicious,they would plant 5/11 rows of Braeburn.

For 11 rows of red delicious,they would plant

$5/11\times 66=5\times 6=30\ rows\ of\ braeburn$

Total rows of trees=66+42+30+18=156
