Answer:

21

Step-by-step explanation:

You know the length of JK 12

you also know the length of GF 2.5*12=30

HL is a mid segment because it cuts both legs it intersects in half.

Using the rule saying that the mid segment is half the bases added up we can figure out that HL = (12+30)/2 = 21

Which ordered pair (x, y) is a solution to given system of linear equations?

patriot [66]

Answer:

$(\frac{1}{6}, \frac{1}{2})$ or $(0.167,0.5)$

Step-by-step explanation:

Given

$3x + y =1$

$15x + y = 3$

Required

Determine the solution

We'll solve using elimination method.

Subtract the first equation from the second:

$15x + y = 3$

$3x + y =1$

$--------$

$15x - 3x + y - y = 3 - 1$

$15x - 3x + y - y = 3 - 1$

$15x - 3x = 3 - 1$

$12x = 2$

Make x the subject:

$x = \frac{2}{12}$

$x = \frac{1}{6}$

$x =0.167$

Substitute $\frac{1}{6}$ for x in the first equation

$3x + y =1$

$3(\frac{1}{6}) + y = 1$

$\frac{1}{2} + y = 1$

Make y the subject

$y = 1 -\frac{1}{2}$

$y = \frac{2-1}{2}$

$y = \frac{1}{2}$

$y = 0.5$

Hence, the solution is:

$(\frac{1}{6}, \frac{1}{2})$ or $(0.167,0.5)$

dexar [7]

2.3s + 4.6h = 4232
s + h = 1030
h = 1030 - s

2.3s + 4.6(1030 - s) = 4232
2.3s + 4738 - 4.6s = 4232
4738 - 4232 = 4.6s - 2.3s
506 = 2.3s
s = 220

h = 1030 - s
h = 1030 - 220 = 810

there were 810 downloads of the high-quality version

torisob [31]

Answer:

24 customers bought 3+ items.

Step-by-step explanation:

80% of 150 = 120

39/120 bought 1 item

57/120 bought 2 items

39 + 57 = 96

120 - 96 = 24

24 customers bought 3+ items.

Hope this helps! :)
