4(2x + 3) ÷ 5y

Mathematics

Step-by-step explanation:

We do the brackets first, following BODMAS rules

so, 4× 5x ÷ 5y = 1xy.

= 4 × 1xy

= 4xy.

I guess that's the answer.

Example Of:-

Sum:

2x + 7y

term: 

5x + 7 = 5x and 7 are terms.

product:

2a × 3b

factor: 

always remember, a number is a factor of itself.

5x + 7y

factors = 5 + x + 5x + 7 + y + 7y.

Quotient: 

10d ÷ 5j = 2dj

coefficient: 

In the number 3x, 3 is the coefficient of x.

but, in the number x (raise to) 2, the coefficient is 1.

Find the area of a triangle formed by placing the vectors [3, 6] and [7, 1] tail-to-tail.

Usimov [2.4K]

Answer:

a. $A=10u^{2}$

b. View graph

c. 6.40u

Step-by-step explanation:

knowing that the triangle area is equal to base by heigh between two, then:

$A=\frac{bh}{2}=\frac{5*4}{2}=10u^{2}$

The length of the longest altitude of your triangle is:

$c^{2}=a^{2}+b^{2}=5^{2}+4^{2}=25+16=41\\ c=\sqrt{41}=6.40u$

finally it can be seen that the position of the triangle does not matter, as long as the base and heigh are maintained, the area of the triangle will be the same

Can you help me on the question

nikdorinn [45]

Answer:
(-3, -2)

Explanation:
-Solve the equation for x-
3x -8y = 7
x= -7 -2y
-Substitute the given value of x into the equation 3x -8y =7
3(-7 -2y) -8y =7
-Solve the equation for y-
y= -2
-Substitute the given value of y into the equation x= -7 -2y
x= -7 -2 x (-2)
-Solve the equation for x
x= -3
-The possible solution of the system is the ordered pair (x, y)
(x, y) = (-3, -2)

In a die game, you roll a standard 6-sided die twice. If the second number rolled is the same as the first number rolled, you wi

Answer:

You can expect to make $250.

Step-by-step explanation:

Possible outcomes:

For the pair of dice:

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)

(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)

(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)

(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)

(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)

(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)

So 36 total outcomes.

Probability of the second number rolled being the same as the first number rolled:

6 outcomes: (1,1), (2,2), (3,3), (4,4), (5,5), (6,6)

Out of 36, thus:

$p = \frac{6}{36} = \frac{1}{6}$

Expected value of 1 game:

1/6 probability of earning $25.

5/6 probability of losing $2.

Thus:

$E = 25\frac{1}{6} - 2\frac{5}{6} = \frac{25 - 10}{6} = 2.5$

100 games:

100*2.5 = 250

You can expect to make $250.
