Answer:

He will travel 520 miles in 8 hours.

Step-by-step explanation:

Given  : A man drove his car a distance of 260 miles in 4 hours. If continuing at this rate is possible,

To find : he will travel ____ miles in 8 hours.

Solution : We have given

Distance = 260 miles.

Time  = 4 hour.

In 4 hour he cover = 260 miles.

In 1 hour he cover =  \frac{260}{4}.

In 1 hour he cover = 65 miles .

So, In 8 hour he cover = 65 * 8 = 520 miles.

Therefore, He will travel 520 miles in 8 hours.

I only (sort of) know 3 and 4

3. Andle 1 is an example of an angle bigger than
{90}^{o} c
I don't know what you call it.

4. If you have a straight line, both angles (or more) added up need to be
{180}^{o} c
so if angle 1 is 129, 180-129=51
angle 2 is
{51}^{o} c

If 1 is what is the relationship between the two angles, then maybe the answer is that they both added up need to be 180 degress (?)

And 2 is probably the same as 3 but with angle 2, angle two is an example of an angle smaller than 90 degrees

Can someone please help on number 20? WILL MARK YOU AS BRAINIEST. (can you also show how you do the problem?) :(
PSYCHO15rus [73]

Answer:

x =(22-√196)/6=(11-7)/3= 1.333

Step-by-step explanation:

(3x2 -  22x) +  24  = 0

The first term is,  3x2  its coefficient is  3 .

The middle term is,  -22x  its coefficient is  -22 .

The last term, "the constant", is  +24

Step-1 : Multiply the coefficient of the first term by the constant   3 • 24 = 72

Step-2 : Find two factors of  72  whose sum equals the coefficient of the middle term, which is   -22 .

     -72    +    -1    =    -73

     -36    +    -2    =    -38

     -24    +    -3    =    -27

     -18    +    -4    =    -22    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -18  and  -4

                    3x2 - 18x - 4x - 24

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3x • (x-6)

             Add up the last 2 terms, pulling out common factors :

                   4 • (x-6)

Step-5 : Add up the four terms of step 4 :

                   (3x-4)  •  (x-6)

            Which is the desired factorization

Equation at the end of step 2:

 (x - 6) • (3x - 4)  = 0

STEP 3:

Theory - Roots of a product

3.1    A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

What is the value of 5n-3 when n=5?
joja [24]

Answer:

22

Step-by-step explanation:

We are given the expression:—

\displaystyle \large{5n-3}

When n = 5, substitute/change n to 5:—

\displaystyle \large{5(5)-3}

Evaluate:—

\displaystyle \large{25-3=\boxed{22}}

__________________________________________________________

<u>Summary</u>

  <u>Substitution</u>

Changing or replacing from a term to another terms/expression is called substitution.

Examples:—

If we are given the expression \displaystyle \large{2y-1} and we want to find the value when y = 4, simply replace y-term to 4.

\displaystyle \large{2(4)-1=8-1=\boxed{7}}

__________________________________________________________

If you have any doubts regarding my answer/explanation, do not hesitate to ask in comment!
