Step-by-step explanation:
54.4 dollars
Solve for x:
1.
4x - 7 = 3
Add 7 to both sides
4x = 10
Divide both sides by 4
x = 10/4
Simplify:
x = 5/2
Answer for question 1: x = 5/2
2.
13 + 2x/3 = 15
Multiply both sides by 3
39 + 2x = 45
Subtract 39 from both sides
2x = 6
Divide both sides by 2
x = 3
Answer for question 2: x = 3
3.
10x + 7 = 15
Subtract 7 from both sides
10x = 8
Divide both sides by 10
x = 8/10
Simplify
x = 4/5
Answer for question 3: x = 4/5
Im not good in math and this is my first question, my best guess is D
I will investigate tommorow this problem a little bit more... <3
Answer:
5.3
Step-by-step explanation:
5 or more raise the score 4 or less let it rest.
3 lets 3 rest so 5.336 rounds down to 5.3.
By the process of elimination I believe that the angle the sun makes with the building is the vertex angle. If that is our reference angle, we have the hypotenuse as 150 and we are looking for the side opposite the reference angle, which we will call x. Therefore, the sin ratio is the one we need, as sin is equal to the side opposite over the hypotenuse.
and 150 sin(75) = x. That gives you an x value of 144.89, first choice above.
