Answer:
9 - y/4 = 13; y = -16.
Step-by-step explanation:
The statement "The difference of nine, and a number divided by four is 13" can be written as an equation in the following way:
9 - y/4 = 13
Now, to find the value of y, we need to solve the equation for y:
→ 9 - y/4 = 13
→ -4 = y/4
→ y = -16.
Therefore, the correct option is the third one.
Step-by-step explanation:
I have used substitution method here to find the value of x and y.
Answer:
21
Step-by-step explanation:
so the relationship is that the music is ten times the commercials so, divide 210 by 30 and times that number by 3 210/30= 7, 7'3=21
Answer:
The side opposite 30 is 9 ft.
The side opposite 60 is 15.59 ft.
Step-by-step explanation:
Below are pictures of how I got the answer.
I will provide steps to accompany each corresponding picture to further explain what I am doing.
1. This picture simply illustrates what the triangle looks like. The Hypotenuse is 18, as described in the problem.
2. I am showing how the sin will work. What is the opposite side and what is the hypotenuse. I picked this particular angle because it allow me to divide it by a number I already have, 18. I show that sin of 30 is 0.5
3. Now, we know what the side value is, 9. We can easily find the remaining side using Pythagorean theorem.
9^2 + y^2 =18^2
81 + y^2 = 324
y^2 = 243
y = 15.59
Answer:
11 cats
Step-by-step explanation:
Given :
Jane's initial = 23
My initial = 2
Jane gives out 5 cats to me ;
Jane's new = 23 - 5 = 18
My new = 2 + 5 = 7
Number of cats Jane has than me :
Jane's new - My new
18 - 7 = 11 cats
