Question 1

Simplify: -6 + 10 +-8

Question 2
Simplify (-3)(6)

Question 3

Simplify
-7 - 18

Answers

Answer:

the answer is to this question is -25

Answer:

1) -4

2) -18

3) -25

Step-by-step explanation:

1)

-6 + -8 = -14

-14 + 10 = -4

2)

Any number multiplied by a negative number will result in a negative product.

So what I do is I multiply as if there was no negative sign: 3 × 6 = 18

Then I add the negative sign to the product: -18

3)

One way you could do this is by switching it around: 18 - -7

Which would make it: 18 + 7 = 25

Then add the negative sign: -25

What is the great GCF (Greatest Common Factor)?
24x^2 and 20x

Answers

First, determine the greatest common factor between the numbers.

Remember, the greatest common factor is just the largest

factor that divides evenly into the two numbers.

In this case, 4 is the largest number so the GCF of our numbers is 4.

For the variables, however, we use the smallest power.

Since we have an x and an x², we use an x.

So our GCF is 4x.

7 + 3 = 10, difference means the answer to a subtraction problem, not sure I understand the question

Step-by-step explanation:

The given expression (7 + 3) represented in difference form as [tex]7-(-3)[/tex]

Difference of numbers :

We have to express 7 + 3 as difference of two number.

As we know that,

           [tex]a-(-b)=a+b[/tex]

In above expression, (a + b) is difference of two number a and -b.

Similarly,

            [tex]7+3=7-(-3)[/tex]

a model for a famous statue is 2 1/2 inches tall. The actual statue is 3 1/3 feet tall. What is the ratio of the height of the model to the height of the actual model in simplest form?

Answers

Answer:

Ratio [Model : Actual] = 1:16

Step-by-step explanation:

Given:

Height of model = [tex]2\frac{1}{2}[/tex] inches = 5/2 inches = 2.5 inches

Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet

Find:

Ratio [Model : Actual]

Computation:

Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet

Height of actual status = [10 / 3] x 12

Height of actual status = 40 inches

Ratio [Model : Actual] = 2.5 / 40

Ratio [Model : Actual] = 1:16

lets take shirts as x and ties as y

Explanation:

Equations -
6x+2y=6
7x+3y=5
Use the 'Elimination Method'
6x+2y=6 --> y=3-3x
Now plug the 'y' into the other equation.
7x+3(3-3x)=5
turns into:
7x+9-9x=5
simplified:
9-2x=5
-2x=-4
----------
x=2

Now plug the x into the 'y=3-3x' equation:
y=3-3(2)
y=3-6

y=-3
