Use the distributive property to write an expression equivalent to 3x+21. *

Answer:

x = -35

Step-by-step explanation:

-8/5x = 56

Start by multiplying both sides by 5 to get rid of the fraction. That will leave you with:

-8x = 280

You can then divide both sides by -8 and then you'll get x = -35

Answer:

x=-35

Step-by-step explanation:

-8/5x is gonna be -1.6x and you divide 56 by -1.6x and get x=-35

Answer:

scientific notation. I did this a few moths ago.

Step-by-step explanation:

since it is 10^8 you're going to move your decimal as far the right as you can which then changes it to 685. x 10^6. After that you add 6 zeros (from the 10^6) and change it from a decimal to a comma to get 658,000,000... i hope this helps

Answer:

The answer is the 2nd one.

Given:

The expression is

[tex]x^2+bx+6[/tex]

To find:

The values of b so that the given expression can be factored into binomials factors.

Solution:

An expression is [tex]ax^2+bx+c[/tex] factorable if b is the sum of possible factors of ac.

We have,

[tex]x^2+bx+6[/tex]

Here, [tex]a=1,b=b,c=6[/tex].

[tex]ac=(1)(6)[/tex]

[tex]ac=6[/tex]

Some, factor forms of 6 are (1×6) and (2×3).

[tex]1+6=7[/tex]

[tex]2+3=5[/tex]

For b=7,

[tex]x^2+7x+6=x^2+x+6x+6[/tex]

[tex]x^2+7x+6=x(x+1)+6(x+1)[/tex]

[tex]x^2+7x+6=(x+1)(x+6)[/tex]

For b=5,

[tex]x^2+5x+6=x^2+2x+3x+6[/tex]

[tex]x^2+5x+6=x(x+2)+3(x+2)[/tex]

[tex]x^2+5x+6=(x+2)(x+3)[/tex]

Therefore, the two possible values of b are 7 and 5.

Answer:

1.)8 boys yo 9 girls

2.)5

Step-by-step explanation:

1)divide by 2

2.) every yellow marble is 1 and there is 5 marbles for each yelllow marble

The ratio of boys to girls in the Grade 6 math class is =

8 : 9.

For every yellow marble, there are five blue marbles.

To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.

To find the ratio of boys to girls in Grade 6 math class simplify by dividing through with two.

Therefore, 16/18 = 8/ 9, that is 8 boys is to 9 girls.

The 5:1 ratio of blue to yellow marbles means for every yellow marble, there are five blue marbles.

Answer:

Yanga ka jhcgjvvhjjio ddd....

Answer:

y=-2/5x +8

Step-by-step explanation:

use y=mx+b      look at where the line intercepts with the y-axis and that is at 8 so that is your b. Then find two points and count how many down or up it is to get from the higher up point (i usually use the one that intercepts at the y-axis) to same line as the other point, in this case thats down two. Then count how many to the right it is and in this case it is 5. so since it went down thats -2 over 5 so then you just fill that into the y=mx+b   and you should get   y=-2/5x+8

Hope this helped!

Answer:

x = 7

y = 4

Arc JKL = 262°

Step-by-step explanation:

Find the diagram attached

Using the theorem;

Sum of opposite angle of the quadrilateral is 180°

7x+131 = 180

7x = 180-131

7x = 49°

x = 49/7

x = 7

Similarly;

11x+y+99 = 180°

11(7)+y+99 = 180°

77+99+y = 180

176+y = 180

y = 180-176

y = 4

arc JKL is the obtuse angle at the centre

Arc JKL = 360-(angle at the centre)

Angle at the centre is twice angle at the circumference.

Angle at the centre = 2(7x)

Angle at the centre = 2(49)

Angle at the centre = 98°

Arc JKL = 360-98

Arc JKL = 262°

Answer:

All you have to do is add 2/4 7 times. So 1/4 times 7 which would equal 7/4=1 3/4

Step-by-step explanation:

Division is one of the four fundamental arithmetic operations. The groups of 1/4 in 7 are 28.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The number of one-fourths in 7, can be found by dividing 7 by 1/4. Therefore, the groups of 1/4 in 7 are,

Number of one-fourth = 7/(1/4)

                                     = (7×4)/1

                                     = 28

Hence, the groups of 1/4 in 7 are 28.

Answer:

12c + 14d - 4

Step-by-step explanation:

16d + 20c + 5d -7 - 8c - 7d + 3

Simplify the expression

__________________________

To solve, we need to first take in mind the fact that there are different like terms within this expression. Like terms are numbers or values that end in different symbols, such as variables or exponents. Since we are filled with variables such as c and d. We can do as followed :

Combine the "d" like terms :

16d + 5d - 7d

21d - 7d

14d

Combine the "c" like terms :

20c - 8c

12c

Combine the constants :

-7 + 3

-4

Now add all of the values together to get the final expression.

12c + 14d - 4

Answer:

14d + 12c + 3

Step-by-step explanation:

1) Add the same variables; if you see d, or c variable add or subtract them like this:

16d + 5d - 7d = 14d

20c - 8c = 12c

3 is left alone b/c there’s no any other number to add/subtract for 3.

also I know whether to add or subtract b/c the addition or subtraction sign would be before the number: ex; - 2, - 3x, + 5d, + 5

2) your equation should look like this....

14d + 12c + 3
