Answer:
Anser is A
Step-by-step explanation:
The image shows a stationary train indicated by letter A and a moving train, indicated by letter B. If the person standing at the train station hears sounds coming from both trains, which explanation best predicts tThe image shows a stationary train indicated by letter A and a moving train, indicated by letter B.

Answer: All but one was right
1. 0 (correct)
2. 34 (correct)
3. 398 (correct)
4. -350 (correct)
5. 20 (correct)
6. 200 (wrong)
7. 48 (correct)
8. -1000(correct)
9. 150 (correct)
10. -55 (correct)
Step-by-step explanation:
(2x5)x(9÷3)+4=10x3+4=30+4=34
4(25x8÷2)+3-5=4(200÷2)+3-5=4x100+3-5=400+3-5=403-5=398
-10x20-30(5)=-200-150=-350
5x10-30=50-30=20
4(50-20÷4)+20=4(50-5)+20=4x45+20=180+20=200
3x4(20÷5)=12x4=48
-20(50x2)+5(200)=-20x100+5x200= -2000+1000=-1000
20x5+70-20=100+70-20=170-20=150
-5+10x(-5)==5+-50=-55
Answer:
0.31
Step-by-step explanation:
one hundredth is 0.01 and 3 tenths would be 0.3 so just add those two together :)
Answer:
b?
Step-by-step explanation:
To answer the question above, use substitution. The method involves substituting y of the second term by the expression for y in terms of x of the first term. This is shown below.
(1) y = 5x + 3
(2) y = 4x + 6
Substituting,
5x + 3 = 4x + 6
Solving for x in this equation gives x = 3. Use this value to solve for y in any of the equations,
y = 5(3) + 3 = 18
Therefore, the answer is letter "D. (3, 18)".
