Answer:
x= 12
Step-by-step explanation:
Here we have vertical angles, this means that they are angles that are across from each other on vertical lines. So, they equal each other.
The equation would be: 60= 5x
The only step is to divide 5 to both sides of the equation.
<u>60</u>= <u>5x</u>
5 5
x= 12
Answer:
a=3.91
Step-by-step explanation:
V=a^3
since volume of B is Half of A then : V of A = 2 volume of B
a^3=2a^3
a^3 for A=60
or ∛a = ∛60= 3.91
volume of B =1/2 A =30
Answer:
37
Step-by-step explanation:
first you need to add 1 plus 4 which is 5. then square it so it becomes 25. Then using order of operations do 6 times 2 which is 12 and add it to 25 to get 37.
First we need to find 75% of $450, so 450x.75=337.5
to find the markup we have to add 450+337.5 to get $787.5.
