Plug y=x-2 into the first equation:
10x-9(x-2)=24
x+18=24
x=6
y=x-2=4
Answer:
2/6 (1/3)
12 gallons
Step-by-step explanation:
3) 1/2x1/3=1/6, so he'd used 1/6 of a tank.
1/2-1/6=
3/6-1/6=2/6. So the tank was 2/6 full, or 1/3 full when he got home.
4) If it's 1/3 full and has 4 gallons, it can hold 12 gallons. (4x3)
The missing statement are:
4. ∠B ≅ ∠B; Reflexive Property of Equality.
5. ΔBDE ~ ΔBAC; Side-Angle-Side (SAS) Similarity Postulate.
<h3>What are the proofs?</h3>
The missing statement are number 4 and 5.
If we say that 4. ∠B ≅ ∠B; Reflexive Property of Equality then:
∠B ≅ ∠B,
Note that there are two triangles, which are ΔABC and ΔDBE and we also have ∠BDE ≅∠BAC and ∠B ≅ ∠B,
∠BDE + ∠B + ∠BED = 180°
∠BAC + ∠B + ∠BCA = 180°
Hence, ∠BED = ∠BCA Substitution property of equality
That birth ΔABC ~ ΔDBE,which is Angle Angle Similarity Postulate

Answer:
123,000 grams
Step-by-step explanation:
1000 mg is equivalent to 1 gram.
Answer:
First, lets look at the side that is already labeled: 5 ft. There are two 5 ft. sides, so the total perimeter so far is 10. I actually compared the 5 ft. side to the side labeled x, and it appears that x = 10. The reason for this is that if you compare both sides, the x side is the same amount as two 5 ft. sides. To calculate the total perimeter, we need to add up the sides: 10 + 10 + 5 + 5 = 30 ft.
hope this helps.
