Take $969.50 and divide it by 7, for the week. You should end up with an answer of $138.50, if I did my math correctly.
Answer:
0
Step-by-step explanation:
8x + 4 = 3x - 3 +7
u first expand the bracket as I have done above
then u evaluate those who have like terms close like -3 + 7
8x + 4 = 3x + 4
then u group like terms ie. the values with the variable x on one side of the equation and the ones without x on the other side of the equation
8x - 3x = 4 - 4
8x - 3x = 0
5x = 0
then u divide both side by the coefficient of x
0/5 but any number divided by 0 is 0, so x = 0

Step-by-step explanation:
Answer:
y = (-2/3)x + 5/6
Step-by-step explanation:
The general structure of a line in slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept. You have been given the value of "m". To find the value of "b", you can plug the slope and the values from the point (2, -1/2) into the general equation.
m = -2/3
Point (2, -1/2):
x = 2 and y = -1/2
y = mx + b <----- Slope-intercept form
y = (-2/3)x + b <----- Insert -2/3 in "m"
-1/2 = (-2/3)(2) + b <----- Insert "x" and "y" values from point
-1/2 = -4/3 + b <----- Multiply -2/3 and 2
-3/6 = -8/6 + b <----- Give the fractions common denominators
5/6 = b <----- Add 8/6 to both sides
Thus, the equation of the line is:
y = (-2/3)x + 5/6
<span>18 mph.
OK. Let's call the speed of the slower cyclist X, And since the faster cyclist is 3 times faster, that speed will be 3X. So their combine closing speed will be (X + 3X) and over a period of 4 hours, they travel 96 miles. So the equation becomes:
4(X + 3X) = 96
Now solve for X
4(X + 3X) = 96
4(4X) = 96
16X = 96
X = 6
So the slower cyclist has a speed of 6 mph. And since the faster cyclist is 3 times faster, that speed is 3*6 = 18 mph.</span>
