Answer:

<em>624 is the answer</em>

Step-by-step explanation:

5x²-3x+5        x=2

plug in x=2: 25²-6+5=?

do the 25²: (25*25=625)

plug in 625 into the equation: 625-6+5

subtract 6 from 625: 625- 6= 619

plug 619 into your equation: 619+5=?

add 5 to 619: 619+5= 624

Step-by-step explanation:

5x² – 3x + 5

Substitute 2 in for x

5(2)² - 3(2) + 5

Solve exponents first

5(4) - 3(2) + 5

Solve/multiply parenthesis

20 - 6 + 5

Add and subtract

Solve for the vector x + 2a - b in terms of the vectors a and b. (If needed, use BOLD vector form on calcPad Vector menu.) x + 2
nikdorinn [45]

Answer:

x+2a-b=5x+5a-2*3a+2*b

x+2a-b=5x+5a-6a+2b

x+2a-b=5x-a+2b

5x-x=2a-b+a-2b

4x=3a-3b

4 x=3(a-b)

x=3/4(a-b)

If it takes one minute to run 130 meters how long will it take to run 1494.23 meters
Rus_ich [418]
We have to see how many times 130 fits into 1494.23:

1494.23/130=11.4940....

So now we have to multiply this by the amount of time needed for 130 meters:
11.4940*1=11.4940.

So the answer is 11.4940 minutes.

Triangle ABC is congruent to triangle DEF. If DE = 41, EF = 23, DF = 36, and AB = 8x − 7, what is x? Round to the nearest tenth.
Nadya [2.5K]

The side AB is equal to the side DE. Then the value of x is 6.

<h3>What is the triangle?</h3>

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

Triangle ABC is congruent to triangle DEF.

If DE = 41, EF = 23, DF = 36, and AB = 8x − 7.

Then the side AB is equal to the side DE.

    AB = DE

8x - 7 = 41

    8x = 48

      x = 6

Then the value of x is 6.

More about the triangle link is given below.

William sold half of his comic books and then bought 14 more he now has 24 with how many did he have in the beginning
Lera25 [3.4K]
Let the number of comic books be X
if we add 14 to X = 24
so we will find the value of X to get half initial number of comic books William had.
14+X=24
X=24-14
X=10
so the total innitial number of comic books William had is 10+10=20 books.
