Answer:

$x=5$

Step-by-step explanation:

CE = EB since E is the midpoint of CB (proven by AD intersecting it).

If CE=EB, then:

$2x=15-x\\$

Add $x$ to both sides

$3x=15\\$

Divide both sides by 3

$x=5$

Answer:

Step-by-step explanation:

Since the diagonals of a parallelogram bisect each other, the two halves must be equal. Therefore:

$15-x=2x \\\\15=3x \\\\x=5$

Hope this helps!

CAN ANYBODY PLS HELP

The correct options are

$5x = - 58 \:$ $5x + 4 = - 54$

<h3>How to find same value of x?</h3>

given that

$\frac{5}{6} x + \frac{2}{3} = - 9$

first find value of x to obtain the equations have the same value of x.

Find the L.C.M between the 6,3

$\frac{5x + 4}{6} = - 9$

Then Cross multiplication should be done

$5x + 4 = - 9 \times 6 \\ 5x + 4 = - 54 \\ 5x = - 54 - 4$

$5x = - 58$

Hence the correct options are

$5x = - 58$

$5x + 4 = - 54$

Question 18

ira [324]

Answer:

The function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

Step-by-step explanation:

Given the sequence

$95, 80, 65, 50, ...$

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$80-95=-15,\:\quad \:65-80=-15,\:\quad \:50-65=-15$

As the difference is the same, so

$d = -15$

$a_1=95$

Thus, substituting $d = -15$ , $a_1=95$ in the nth term of an arithmetic sequence

$a_n=a_1+\left(n-1\right)d$

$a_n=-15\left(n-1\right)+95$

$a_n=-15n+110$

Therefore, the function which represents this sequence will be:

$a_n=-15n+110$

Hence, option (A) is true.

So the students are on 5:6 ratio from volleyball to football, and we know there are 220 students in total.

$\bf \cfrac{volleyball}{football}\qquad 5:6\qquad \cfrac{5}{6}\implies \cfrac{5\cdot \frac{220}{5+6}}{6\cdot \frac{220}{5+6}}\implies \cfrac{5\cdot 20}{6\cdot 20}\implies \cfrac{100}{\stackrel{football}{120}}$
