Answer:
d = 25
Step-by-step explanation:
Perhaps you want to solve for d:
(0.3d -1.5)/(3 1/3) = 0.84/(7/15)
Change the division by a fraction to multiplication by its inverse.
(0.3d -1.5)·(3/10) = (0.84)·(15/7)
0.09d -0.45 = 1.8 . . . . . . . . . . . . simplify
d - 5 = 20 . . . . . . . . . . . . . . . . . . divide by 0.09
d = 25 . . . . . . . . . . . . . . . . . . . . . add 5
_____
Grouping symbols help show what is being divided by what. Especially where mixed numbers are involved, parentheses help show that the number 3 1/3 is not supposed to be interpreted as the product of 3 and 1/3.
Y = 4x - 3
y = 1/3x + 4
y = -4/5x + 5
y = 3x + 10
Answer:
The answer to your question is below
Step-by-step explanation:
Data
A (4 , -3)
r = ?
sin = ?
cos = ?
tan = ?
Process
1.- Plot the point
This point is in the fourth quadrangle
2.- Calculate r
We have the Opposite side and the Adjacent side
tan Ф = -3/4
tan⁻¹ Ф = Ф = 323.1
Ф = 323.1°
3.- sinФ =
Calculate the hypotenuse
c² = 4² + (-3)²
c² = 16 + 9
c² = 25
c = 5
sinФ = -3/5
cos Ф = 4/5
tan Ф = -3/4
Answer:
y = 4x - 8
Step-by-step explanation:
x = 1/4y + 2
-1/4y -1/4y
-1/4y + x = 2
-x -x
-1/4y= -x + 2
*-4 *-4
y = 4x - 8
The value of x - coordinate is 14.4
<em><u>Solution:</u></em>
Given that we have to find the x -coordinate of the system
<em><u>Given system of equations are:</u></em>
2x + 3y = 144 -------- eqn 1
y - x = 24 --------- eqn 2
Solve the above system of equations to find the x - coordinate
From eqn 2,
y = 24 + x ------- eqn 3
Substitute eqn 3 in eqn 1
2x + 3(24 + x) = 144
2x + 72 + 3x = 144
Add the like terms
5x + 72 = 144
5x = 144 - 72
5x = 72
Divide 72 by 5
x = 14.4
Thus the x - coordinate of the system is 14.4
