Answer:

13

Step-by-step explanation:

Do the distributive property=-3z-24+10=-5

subtract 10 from -5= -3z-24=-15

subtract 24 from -15 = -3z=-39

divide -39 by -3= z=13

voila

BRAINLIEST AND 30 POINTS FOR WHOEVER CAN EXPLAIN HOW TO GET THESE ANSWERS...
Dvinal [7]

Step-by-step explanation:

  • Since m∠ACM = 90°, then by angle addition, m∠ACP + m∠PCM = 90°.
  • Since CP⊥ AM, then by definition of perpendicular, m∠APC = 90°.  Since angles of a triangle add up to 180°, that means m∠PAC + m∠ACP = 90°.
  • By substitution, m∠PCM = m∠PAC.
  • Since m∠PCM + m∠CMP = 90°, then by substitution, m∠CMP = m∠PAC.
  • Therefore, by AAA, △ACP and △CMP are similar.

Having proven that the triangles are similar, we can write the proportion:

AP / CP = CP / MP

9 / CP = CP / 16

CP² = 144

CP = 12

Now, we can simply use Pythagorean theorem to find the other sides.

AC² = AP² + CP²

AC² = 9² + 12²

AC = 15

CM² = CP² + PM²

CM² = 12² + 16²

CM = 20

I need help with this
Assoli18 [71]
On a given line, (on one side) there are a total of 180°

if one line in Problem #3 is bisected by a line, with one half X and the other 120°,

do 180° (the total) minus 120° which=60°

now the hard part, that line that bisected the first line is bisecting a line that is parallel to your second line, the one with <5 and <6

this means that the big angle formed in the first one with 120° is the same angle as in the second line, leaving <5 as 120°
which means <6 is 60°, like in the top part of the problem. You're basically flipping the top line upside down, I hope it helps.

-7-5x+5x+7 simplified​
AysviL [449]

Answer:

0

Step-by-step explanation:

adding -7 to 7, since they are both constants (no variable) gives you 0. Adding -5x and 5x since they both have an x term gives you 0x also written as 0 (0*any number is 0). this gives you a final answer of 0
