Use two mixed numbers to write an equation with a sum of 4 1/4

Answers

Answer 1

Answer:

The required equation is given as 2 1/8 + 2 1/8, as of the given condition,

Given that,
To use two mixed numbers to write an equation with a sum of 4 1/4.

What is the fraction?

Fraction is defined as the number of compositions that constitute the Whole.

What is a mixed number?

A mixed number is in the form a b/c which is represented as a + b/c.

Here,
let the missed number be x
Now,
according to the question,
x + x = 4 1/4
2[x ] = 4 1/4
x = 2 1/8

Thus, the required equation is given as 2 1/8 + 2 1/8, as of the given condition,

What is x ? 4x+8y =64

Answers

4x +8y=64

subtract 8y on both sides
4x=-8y +64

divide by 4 both sides with all #
x=-2y+16

The given equation is --> 4x + 8y = 64
==> 4x = 64 - 8y
==> x = 64/4 - 8y/4
==> x = 16 - 2y

So, the final answer is --> x = 16-2y

Factor 6x2 - 33x + 15

Answers

Answer:

Step-by-step explanation:

6x² -33x + 15 =6x² -30x - 3x + (-3)*(-5)

=6x(x - 5) - 3(x - 5 )

=(x-5) (6x-3)

Answer:

3(2x - 1)(x - 5).

Step-by-step explanation:

6x2 - 33x + 15

= 3(2x^2 - 11x + 5)

= 3(2x - 1)(x - 5).

PLZ ANSWER RIGHT AWAY!!!!!!!!!!!!!Darrell completed 1/8 of his project in 3 3/4 minutes.

At this pace, how long does it take Darrell to complete his project?

A. 15/32
minute

B. 2 2/15
minutes

C.
15 minutes

D.
30 minutes

Answers

1/8 = 3 3/4 minutes

1/8 × 8 = 1 project

1/8 x 8 = 3 3/4 × 8

1 project = 3 3/4 × 8 minutes

$3 (3)/(4) *8$

$(15)/(4) * (8)/(1)$

$(120)/(4)$

30 minutes

1 project = 30 mintues
The answer is D

$3 (3)/(4) = (15)/(4)\n\n (15)/(4) * 8= 15 * 2= \huge{\boxed{30}}$

Your answer is D. :D

Two cyclist leaves town 200 mi apart at the same time and travel toward each other. One travels at 10mi/h slower than the other. The they meet in 5 hours, what is the rate of each cyclist

Answers

Let x be the rate of speed of slower cyclist

and x+10 = rate of speed of faster cyclist

Distance = Speed * Time

5x + 5(x+10) = 200

5x + 5x + 50 = 200

10x = 200-50

10x = 150

x = 15

Rate of speed of slower cyclist: 15 mph

Rate of speed of faster cyclist = 15+10 => 25 mph

Final answer:

In this problem, the speed of the faster cyclist is 25 mi/h and the speed of the slower cyclist is 15 mi/h. We determine this by setting up and solving an algebraic equation considering the total distance and time they traveled.

Explanation:

This problem is a typical example of relativerate and distance problems in algebra. First, define the speed of the faster cyclist as x m/h. Then, the speed of the slower cyclist is x-10 m/h. They travel towards each other, so their rates add up. That's why the equation becomes x+(x-10) = 200/5. We get this equation because the total distance they traveled is 200 miles (meeting in the middle), and they traveled for 5 hours.

Solving the equation x+(x-10) = 40 gives 2x-10 = 40, then 2x = 50, and finally x = 25. So, the faster cyclist is moving at 25 mi/h, and the slower cyclist is moving at 15 mi/h (25-10).
