Answer:
x=60
Step-by-step explanation:
I'm assuming you meant this: (x/5)-8=4
In which case you would add 8 to both sides to get rid of the 8 on the left (your goal is to get x by itself so you want to move the numbers on the x side to the other side of the equal sign)
(x/5)=12
Then you would multiply 5 on both sides to get rid of the fraction with the 5 on the bottom on the left side.
x=60
There's your answer.
Answer:
arctan(4/3) ≈ 0.9272
Step-by-step explanation:
On comparing eqⁿ to y = mx + c,
Slope of 2x + 4y = 7 is -2/4 = - 1/2
Slope of x + 2y = 5 is - 1/2
Therefore, if A is the angle b/w them,
A = arctan | (m1 + m2)/(1 - m1m2) |
A = arctan | (-½ - ½)/(1 - ¼) |
A = arctan (4/3)
1. If a and b vary inversely and b = 8 when a = 6:
b = k/ a
8 = k / 6
k = 6 * 8
k = 48
Function is:
b = 48 / a
2. When a = 30:
b = 48 / 30 = 8/5
b = 1.6
