20 and that should be correct, if you need an explanation just ask
Answer:
Step-by-step explanation:
<u>First, Let's solve for x in -2x+2y=-4:</u>
<u>Subtract 2y from both sides:</u>
<u>Divide both sides by -2:</u>
<u>Now, we'll substitute x=y+2 to 3x+3y=-18:</u>
→ let x=2+y
<u>Simplify:</u>
<u>Now, let's solve for y in 6+6y=-18</u>
<u>Subtract 6 from both sides:</u>
<u>Divide both sides by 6:</u>
<u>Now, substitute y=-4 into x=2+y:</u>
→ let y = -4
Therefore, x=-2 and y=-4.

Answer:
for m∠SRQ x = 3
for m∠QRP x = 5
Step-by-step explanation:
1. 6x +2. 6 is being multiplied by a number so to find that number we do teh opposite
6x/2 = 3
drop the x then u have x = 3
2. 2x+10. 2 is being muliplied by a number so to find that number we do teh opposite
10/2x = 5
drop the x then u have x = 5
400. Just add a zero when you're dealing with tens
Answer:
10 ≥ w ≥ 9 ( ? )
Step-by-step explanation:
the probability that a Great blue heron is at least 9 pounds, but no more than 10 pounds -> w= weight of great blue heron
w is at lest 9 pound's -> w ≥ 9
w is no more than 10 pound's -> w ≥ 10
w ≥ 9 ( + ) w ≥ 10 = 10 ≥ w ≥ 9
