Answer:

Step-by-step explanation:

11 = 11*1

8 = 2*4

They have no common factors, so the LCM (least common multiple) is

2*4*11 = 88

The multiples of 8 and 11 below 600 are multiples of 88

88*1 =88

88*2 =176

88*3 =264

88*4 =352

88*5 =440

88*6 =528

This is the last multiple because if we add 88 if would be over 600

1/4+3/8 and show work, please!!

gregori [183]

Answer:

The answer is 5/8

Step-by-step explanation:

Step 1 : Convert both fractions so they have the same denominator (bottom number in the fraction.)

1/4 = 2/8

So now were dealing with :

2/8 + 3/8 = ?

Step 2 : Add the numerators together to get the numerator for our answer.

2 + 3 = 5

When adding two fractions with the same denominator the denominator stays the same, so our answer is 5/8.

Hope this helps, please mark brainliest. :) Have a nice day.

F (x) = -3x + 2x – 5 Whatisf (-1)?

eduard

Answer:

f(-1) = -4

Step-by-step explanation:

f(-1) simply means that what is f(x) when x = -1?

Just plug in -1 for <em>x</em> to find your answer:

f(-1) = -3(-1) + 2(-1) - 5

f(-1) = 3 - 2 - 5

f(-1) = 1 - 5

f(-1) = -4

Roy and Sam start solving the equation as follows.

denpristay [2]

Answer:

The correct option is D.

Step-by-step explanation:

The given equation is

$-3x+4=5x-6$

According to the addition property of equality $a=b$ and $a+c=b+c$ are equivalent equations.

Use addition property of equality, add 3x on both the sides.

$-3x+4+3x=5x-6+3x$

$4=8x-6$

Therefore Sam's work is incorrect because he make calculation mistake.

According to the subtraction property of equality $a=b$ and $a-c=b-c$ are equivalent equations.

Use subtraction property of equality, subtract 5x from both the sides.

$-3x+4-5x=5x-6-5x$

$-8x+4=-6$

Therefore Roy's work is correct because he used subtraction property.

Option D is correct.

1. 5 x 4 = A. 20

$\frac{2}{5} \times 25 = 2 \times 5 = 10$

the answer is D. 25

$\frac{3}{5} \div 15 = \frac{3}{5} \times \frac{1}{15} = \frac{1}{5} \times \frac{1}{5} = \frac{1}{25}$

the answer is A. 1/25

$4 \div \frac{1}{2} = 4 \times \frac{2}{1} = 8$

the answer is C. 8

$9 \div \frac{1}{3} = 9 \times \frac{3}{1} = 27$

the answer is D. 27

$20 \div \frac{1}{4} = 20 \times \frac{4}{1} = 80$

the answer is D. 80

$\frac{9}{10} \div \frac{1}{2} = \frac{9}{10} \times \frac{2}{1} = \frac{18}{10} = \frac{9}{5} = 1 \frac{4}{5}$

the answer is C. 1 4/5

$9 \div \frac{3}{2} = 9 \times \frac{2}{3} = \frac{18}{ 3} = 6$

the answer is B. 6

$\frac{3}{4} \div \frac{3}{8} = \frac{3}{4} \times \frac{8}{3} = 2$

the answer is A. 2

19) Solve the inequality. 7x − 9 > 2x + 6 A) x > 3 B) x > 3 5 C) x > −3 D) x > − 3 5

Marianna [84]

Answer:

Step-by-step explanation:

Given

7x - 9 > 2x + 6 ( subtract 2x from both sides )

5x - 9 > 6 ( add 9 to both sides )

5x > 15 ( divide both sides by 3 )

x > 3 → B
