Help me with this question......
4. The diagram on the right shows a trapezium PQRS where PQ=(x-1) cm, PS = (x+3) cm and QR = (3x + 2) cm.
Given the area of the trapezium is 17 cm", find the value of x.


​

Answer:

15

Step-by-step explanation:

We can find value of x using similarity ratio

(3x-5)/32 = (5x-5)/56 cross multiply expressions

56×(3x-5) = 32×(5x-5)

21x - 20x = 35 - 20

x = 15

-6-4=-10

-10/-5=2

so 2 is ur answer

Answer:

The answer is B.3 because

3*11=33+22=$55

3*9=27+28=$55

Answer: 10/3 is the answer here you go

Answer:

10/3

Step-by-step explanation:

One trick I learned for writing improper fractions is multiply the whole number by the denominator to then add to the numerator. So in this case 3*3=9 and 9+1=10. So the improper fraction is 10/3

Answer:

The mean = 17.54

Step-by-step explanation:

Form a table as below;

Interval         Frequency{f}      Midpoint of frequency{x}          fx    

1-7                    19                         4                                            76

8-10                  14                         9                                            126

11-15                  15                         13                                           195

16-20                20                        18                                           360

21-35                 10                        28                                          280

36-50                13                         43                                          559

Sum                   91                                                                        1596

The mean  of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency

The mean= 1596 / 91

The mean = 17.54

Answer:

25 is the total length

Step-by-step explanation:

Distance driven = 15

Which Is 3/5 of the way home

Total length of drive

The unknown = x which is the total length of his drive

From the statement in this question 15 is three-fifth of c

So we have this equation:

(3/5)x = 15

We divide both sides by (5/3) so that x can stand on its own

(3/5)(5/3)x = 15(5/3)

(15/15)x = 75/3

x = 25

The total length of the drive is 25

Answer:

x=10

Answer:

4 more students

Step-by-step explanation:

To find how many more students Mrs. K has, subtract 19 from 23:

23 - 19

= 4

So, Mrs. K has 4 more students than Mr. Curran

The triangle in the diagram is a right-angled triangle. This means that one of the measures of the angles is 90°.

We know that the sum of the angles in a triangle is 180°.

In the diagram, two angles are represented by 'x', indicating that those two angles are of the same measures.

And we know that one of the angles is 90°.

So according to the angle-sum property, the following equation can be framed:

x + x + 90° = 180°

Solving the equation,

2x + 90° = 180°

2x = 180° - 90°

2x = 90°

x = 90°/2

x = 45°

Therefore, the value of x is 45°.

Answer:

408+8

Step-by-step explanation:

The expression is equivalent to (20+8) is 4(2+5)

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, 20+8, we need to find an expression is equivalent to 20+8

So, the expression is 20+8

We can write =

4x5 + 4x2

= 4 (5+2)

Hence, the expression is equivalent to (20+8) is 4(2+5)

Answer:

1/2 (slope)

-5 (y-intercept)

Step-by-step explanation:

the slope-intercept formula is y=mx+b

m is the slope and y is the y-intercept. therefore the numbers that are substituting the position of the variables are the slope and intercept

y=1/2x-5

1/2 is substituting for m which is the variable for slope

-5 is substituting for b which is the variable for the y-intercept
