1. Add a positive integer by moving to the right on the number line.
2. Add a negative integer by moving to the left on the number line.
3. Subtract an integer by adding its opposite.
Answer:
4.04 (idk how you want it rounded)
Step-by-step explanation:
1) Use TOA
the equation should look like: Tan30= x/7
2) multiply each side by 7 and you’re left with 7Tan30= x
3) in your calculator do 7x30Tan equals and you get your answer
Numerator:
the product of 5 and the sum of x and y = 5(x + y)
Denominator:
the product of negative 8 and x = -8x
So the quotient:
5(x + y)
------------
- 8x
Answer is the second one.
5(x + y)
------------
- 8x
2(-12) isn't 24.
It is -24.
So the answer would be 6.
Answer:
C
Step-by-step explanation:
Parallel and opposite sides of a parallelogram are equal. Hence, we can say:
x + 30 = 2x - 10
and
2y-10 = y +10
Solving first one, we get:
x + 30 = 2x - 10
30+10 = x
x = 40
Also
2y - 10 = y + 10
y = 10 + 10
y = 20
Now, z = x - y, so
z = 40 - 20 = 20
Answer C is right.
