Can someone please explain how to find the difference -7 - (-8)

Answers

Answer 1

Answer:

1

Step-by-step explanation:

In the equation -7 - (-8), there are two 'minus' signs; we can convert two minus signs into a plus sign according to the 'minus minus equals plus' rule, that would make the equation (-7) + 8 for which the answer is +1.

Answer 2

Answer:

1

Step-by-step explanation:

-7-(-8)

First you should solve the brackets.Remeber (-) minus into (-) equal (+)

therefore;

  -7-(-8)= -7+8

when there is a minus and a plus you should minus the two numbers and put the largest value sign.

therefore;

   -7+8= 1

Hope you understand.If you have any problem just ask me I will solve it.

Answers

Answer:

[tex] k = \dfrac{5}{3} [/tex]

Step-by-step explanation:

It is actually a one-step equation.

If you have a number multiplying a variable equaling another number, then you need to do only one operation to solve; you need to multiply both sides by the reciprocal of the number multiplying the variable.

Here we have

[tex] \dfrac{3}{2} = \dfrac{9}{10}k [/tex]

First, switch sides to have the variable, k, on the left side.

[tex] \dfrac{9}{10}k = \dfrac{3}{2} [/tex]

You have a variable, k, multiplied by a number, the fraction 9/10, equaling another number, 3/2. To solve for k, multiply both sides by the reciprocal of 9/10 which is 10/9.

[tex] \dfrac{10}{9} \times \dfrac{9}{10}k = \dfrac{10}{9} \times \dfrac{3}{2} [/tex]

On the left side, you have the product of two reciprocals, 10/9 and 9/10, which equals 1, leaving just k.

On the right side, you must multiply the fraction 10/9 by 3/2 and then reduce.

[tex] k = \dfrac{30}{18} [/tex]

[tex] k = \dfrac{5}{3} [/tex]

WILL.MARK BRAINLEST. ( The length of a rectangular garden is 5m longer than its breadth .If its perimeter is 150 m,find the area of the garden ) step by step​

Answers

Answer:

1400m^2

Step-by-step explanation:

Let the breadth of the garden be a, therefore the length of the garden is (a+5).

The perimeter of the garden is the sum of all its sides, therefore:

Perimeter = a + a + (a+5) + (a+5) = 150

Simplifying the LHS of the equation:

4a +10 = 150

Subtracting 10 from both sides of the equation:

4a = 140

Dividing both sides by 4:

a = 35 = breadth

Therefore the length of the garden = (a + 5) = 40

Recall that the area of the garden is its length multiplied by its breadth, therefore:

Area = 35*40 = 1400

Answer:

area=1400

Step-by-step explanation:

length(l)=x+5

breadth(b)=x

Perimeter=2(l+b)

      150    =2(x+5+x)

         150 =2x+10+2x

    150-10=4x

       140=4x

         x=35          

therefore breadth=35

                 length=40

area=l*b

      =35*40

     =1400

y=3

Step-by-step explanation:

6=2(y+2)-4

6=2y+4-4

6-4+4=2y

6=2y

3=y

The answer you are looking for is y=3.

Solution/Explanation:

First, writing out the problem,

6=2(y+2)-4.

Next, using the Distributive Property for 2(y+2), which is 2y+4,

6=2y+4-4.

Now, canceling out the 4, since 4-4=0,

6=2y+0, or 6=2y.

Finally, dividing both sides by 2,

6/2=2y/2.

6/2=3.

2y/2=y.

3=y, or y=3.

So, therefore, the final answer is y=3.

Samuel invested money in his bank account. He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, r, of 0.15 per year. At the end of the period, he had interest, I, of $105 in his account. Use the simple interest formula I = Prt, to solve for the time, t, in months that it took to earn this amount.

Answers

Hey there! I'm happy to help!

Let's see what we have for each variable.

I = 105

P = 100

r = 0.15

Now, let's plug it in and solve for our t (time)

105=100(0.15)(t)

Swap sides so t is on the left.

100(0.15)(t)=105

Divide both sides by 100.

0.15t=1.05

Divide both sides by 0.15

t=700

So, we see that it takes 700 months to earn this amount.

Have a wonderful day and keep on learning! :D

The number of months that it took to earn this amount will be 84 months.

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where P is the principal, R is the rate of interest in percentage, and T is the time.

Samuel invested money in his bank account.

He had a principal, P, of $100 in his account at the beginning of the period, which increased at a rate, R, of 0.15 per year.

At the end of the period, he had interest, I, of $105 in his account.

105 = 100 x 0.15 x t

t = 1.05 / 0.15

t = 7 years

The number of months that it took to earn this amount will be

⇒ 7 x 12

⇒ 84 months

The number of months that it took to earn this amount will be 84 months.
