Answers

Answer 1

Answer:

a-5, b-4, c-1, d-3, e-2

Step-by-step explanation:

1) 3x+4 = 7x-8

-4x = -12

x = -3 (c)

2) 2x = 7x-5

-5x = 5

x = 1 (e)

3) 5x-8 = 5x+12

0x = 20

no solution (d)

4) 8x+4 = -2x-16

10x = -20

x = -2 (b)

5) -3x+5 = -3x+5

all real numbers (a)

Prove that the sum of five consecutive natural numbers is even.
pls explain briefly and pls help it has 14 pts

Answers

Answer:

Conversely, if n is divisible by 5, then n is the sum of five consecutive integers. In particular, this gives n = 5m + 10 = 5(m + 2) and, since m + 2 is an integer, this shows n is divisible by 5

You cannot prove it, because it isn’t true. 1+2+3+4+5 = 15.
n+(n+1)+(n+2)+(n+3)+(n+4) = 5n+10 = 5(n+2)

Answer:

Step-by-step explanation:

What is 5/9 - 3/8?

What is 5/9 - 3/8?

Here's how to subtract 3/8 from 5/9:

5

9

3

8

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 5 by 8, and get 40.

Then we multiply 3 by 9, and get 27.

Next we give both terms new denominators -- 9 × 8 = 72.

So now our fractions look like this:

40

72

27

72

Step 2

Since our denominators match, we can subtract the numerators.

40 − 27 = 13

So the answer is:

13

72

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

Video Player is loading.

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

Nope! So now we try the next greatest prime number, 13...

Nope! So now we try the next greatest prime number, 17...

No good. 17 is larger than 13. So we're done reducing.

There you have it! The final answer is:

13/72

Step-by-step explanation:

Given

Required

Solve for t

[tex]-100 = -\frac{t}{5} - 4[/tex]

Add 4 to both sides

[tex]4-100 = -\frac{t}{5} - 4+4[/tex]

[tex]4-100 = -\frac{t}{5}[/tex]

[tex]-96 = -\frac{t}{5}[/tex]

Which one has the variable?

A company makes two models of television.
Model A has a rectangular screen that measures 44 cm by 32 cm.
Model B has a larger screen with these measurements increased in the ratio 5:4.
Work out the measurements of the larger screen.​

Answers

Answer:

16/25

Step-by-step explanation:

length of screen B=44*(5/4)=55cm

and its width=32*(5/4)=40cm

so, screen B had dimensions 55cm by 40 cm

screen A area=44*32 cm sqr

screen B area=55*40 cm sqr

so, model A screen area/model B screen area

=(44*32)/(55*40)

=16/25

There are two numbers which sum to 16. If one number is eight less than three times the other, find the numbers.

Answers

Answer:

The two numbers are 10 and 6.

Step-by-step explanation:

Let the two numbers be a and b respectively.

Translating the word problem into an algebraic equation, we have;

a + b = 16 .........equation 1

a = 3b - 8 .......equation 2

Substituting eqn 1 into eqn 2, we have

3b - 8 + b = 16

4b = 16 + 8

4b = 24

b = 24/4

b = 6

To find the value of a;

a = 3b - 8

a = 3(6) - 8

a = 18 - 8

a = 10

Therefore, the two numbers are 10 and 6.
