Answer:
Step-by-step explanation:
<u>Let the number be x</u>
- 380% of x is 99
- x*3.8 = 99
- x = 99/3.8
- x = 26 rounded to the nearest whole number
Answer:
3/8
Step-by-step explanation:
the answer is 3/8 because u are muliplying 1/2 and 3/4 and 1×3 is 3 and 2×4 is 8 3/8
Answer:
15
Step-by-step explanation:
It is a right angle so it will add up to 90 degrees.
This is the equation:
x=90-19-56
x=15
Answer: option. y=-1.33x; 2.67
Solution:
If y varies directly with x, the relation between y and x is:
y=kx
where k is a constant of proporcionality.
We know y=8 when x=-6. Replacing these values in the equation above:
8=k(-6)
8=-6k
Solving for k: Dividing both sides of the equation by -6:
8/(-6)=-6k/(-6)
-1.33=k
k=-1.33
Then the relation between y and x is:
y=kx→y=-1.33x
What is the value of y when x=-2?
Replacing x by -2 in the formula:
y=-1.33x→y=-1.33(-2)→y=2.66
