If u have a solid dot, then there is an equal sign in the inequality....if it is shaded to the right, u use a greater then sign....if it is shaded to the left, u use a less then sign
3. solid dot on -1, shaded to the right......x > = -1
4. solid dot on 5, shaded to the left.....x < = 5
Answer: y = 6 x = 0.2
Step-by-step explanation:
5x+y=7
20x+2=y
re-write one
5x + y = 7 OR y = 7 - 5x
substitution
20x + 2 = 7 - 5x
20x + 5x = 7 - 2
25 x = 5
x = 5/25
x = 0.2
now for finding y
y = 7 - 5x
y = 7 - 5(0.2)
y = 7 - 1
y = 6
Answer:
960 sprinkles
Step-by-step explanation:
384 sprinkles divided by 24 cookies is 16 sprinkles per cookie. so 16 sprinkles per cookie times 60 cookies is 960 sprinkles.
Let us break the shape into two triangles and solve for the unknowns.
The first triangle is shown below:
We will use the Pythagorean Theorem defined to be:
Therefore, we can relate the sides of the triangles as shown below:
Solving, we have:
Hence, we can have the second triangle to be:
Applying the Pythagorean Theorem, we have:
Solving, we have:
The values of the unknowns are:
