x + 5 ≤ 13 what's the answer for this question?​

Answer:

9/4

Step-by-step explanation:

-3x+10=5x-8

or, -3x-5x = -8-10

or, -8x=-18

or, 8x=18 (i.e. - is cancelled)

or, x=18/8

i.e. x=9/4

Hence, the value of x is 9/4

Answer:

The value of x is 9/4

Step-by-step explanation:

-3x+ 10 = 5x - 8

Add 3x both side

-3x + 3x + 10 = 5x + 3x - 8

10 = 8x - 8

Now, Add 8 both side

10 + 8 = 8x - 8 + 8

18 = 8x

8x = 18

Now, Divide by 8 from both side

8x/8 = 18/8

x = 9/4

Thus, The value of x is 9/4

-3x + 10 = 5x - 8

-3(9/4) + 10 = 5(9/4) - 8

-27/4 + 10 = 45/4 - 8

-27 + 4 × 10/4 = 45 - 8 × 4/4

-27 + 40/4 = 45 - 32/4

13/4 = 13/4

Hence, L.HS = R.H.S

Answer:

∠MKN = 30°

Step-by-step explanation:

∠PKL = 2x

∠MKN = x

2x + x = 90

3x = 90

x = 30

∠MKN = 30°

Answer:

  a) 1/2

  b) 1/2

Step-by-step explanation:

a) The average rate of change is the slope of the segment whose end points are the ends of the interval. On the interval [2, 8] the average rate of change is ...

  m = (f(8) -f(2))/(8 -2) = (4 -1)/6 = 3/6 = 1/2

The average rate of change on the interval [2, 8] is 1/2.

__

b) In this context, "slope" and "average rate of change" mean the same thing. A line with the same slope will have a slope of 1/2.

Answer:

6 1/3 yards = 19 feet

Step-by-step explanation:

1 yard = 3 feet

So we'll take the number of yards and multiply that by 3

6 yards x 3 feet/yard = 18 feet

for the 1/3 of a yard, you can either ask, "what's 1/3 of 3?" (= 1) or you can multiply 1/3 yard x 3 feet/yard = 1 foot.

Add up the parts, 18 + 1 = 19 feet

Answer:

  A.  The volumes are equivalent.

Step-by-step explanation:

The volume of a pyramid can be found using the formula ...

  V = 1/3Bh

where B is the base area, and h is the height.

Both of these pyramids have the same height, so we can compare volumes by looking at the base area.

Prism X has a rectangular base with an area of A = LW = (6 cm)(5 cm) = 30 cm². Prism Y has a triangular base with an area of A = 1/2bh = 1/2(7.5 cm)(8 cm) = 30 cm².

The two base areas are the same, so the volumes are the same.

Answer:

72

Step-by-step explanation:

every angle in a triangle adds up to 180

57 + 51 + x = 180

x = 72

Answer:

The answer to the question is:

x=72°

Step-by-step explanation:

The total angles of a triangle is 180°

x+51°+57°=180°

x+108°=180°

x=180°-108°

x=72°

Step-by-step explanation:

bottom to top

it goes from -1 to 1

The required range of the function y= cosx is [-1, 1]. Option C is correct.

From the graph range of the function y = cosx is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is independent while Y is the dependent variable.

The range is defined as the difference between higher and lower values of y = f(x).

In a graph the value of y = f(x) = cosx is defined for every x of its domain (-∞, ∞) it varies from minimum -1 to maximum +1 on the y axis, so the range of the function is [ -1, 1].

Thus, the required range of the function y= cosx is [-1, 1]. Option C is correct.

Answer:

perpendicular

Answer:

Perpendicular

Step-by-step explanation:

Answer:

25

Step-by-step explanation:

This is the probability that corresponds to x = -5, which is less than x = -3, and it's the only x value of the list smaller than -3. There's not much else to say about this.

If we wanted to find something like P(X < -2), then we would add up the probabilities for x = -5 and x = -3 to get 0.17+0.13 = 0.30

6=3

As, 1= one which is 3 alphabets so, ....

Step-by-step explanation:

The accurate statement is A. Apples cost approximately $0.07 less per pound.

The constant of proportionality would give us the cost of per pound. From the graph, when number of pounds (p) = 3, cost in dollars (C) = 4.

Constant of proportionality = C/p = 4/3

Therefore, Cost of apples per pound = 4/3 = $1.33 (approximated)

[tex]C = \frac{7}{5} p[/tex]

The constant of proportionality of the equation function will give us the cost per pound for pears.

From the equation, the we can deduce that [tex]\frac{7}{5}[/tex] represents the cost of pears per pound (constant of proportionality).

Thus:

Cost of pears per pound = 7/5 = $1.40

The difference between the cost per pound of pears and the cost per pound of apples would be:

$1.40 - $1.33 = $0.07

Therefore, we can conclude that apples cost approximately $0.07 less per pound.

Answer:

3:00 pm

Step-by-step explanation:

Given

[tex]Rob = 4\ hrs[/tex]

[tex]Joan = 3\ hrs[/tex]

[tex]Start\ Time = 3:00\ am[/tex]

Required

The next time they leave at the same time

To do this, we first list out the multiples of 4 and 3 (i.e. their time of completing each route)

So, we have:

[tex]Rob: 4, 8, 12, 16, 20...[/tex]

[tex]Joan: 3,6,9,12,15,18....[/tex]

The least common multiple in the above is:

[tex]Least = 12hrs[/tex]

This means that they will meet at the terminal after 12 hours

So, their meeting time is:

[tex]Time = 3:00am + 12\ hrs[/tex]

[tex]Time = 3:00\ pm[/tex]
