Solve for x
Answer:
x=4.39024390244
Step-by-step explanation:
21x-3+20x+3=180
group up like terms
41x+0=180
41x=180
/41 /41
x=4.39024390244
simplify if needed
fraction form: 180/41
Solve for x in terms of a and b: 2x + a = b
Answer:
x=a+b/2
Step-by-step explanation:
1. adding a to both sides
2. dividing both sides by 2
2x-a=b
2x=a+b
x=a+b/2

John's family visited his grandmother over the weekend. the drive to her house was 2 hours at their usual speed. the trip back took 15 min longer because traffic was bad and they had to drive 5 mph slower. how many miles away is Johns's grandmother's house?
The distance to Johns's grandmother's house is 90 miles.
SpeedSpeed is the ratio of total distance to total time taken, it is given by:
Speed = distance / time
Let x represent the speed that John used and d represent the distance, hence:
x = d/2
Also when taken 15 minute longer (0.25 hours):
x - 5 = d/(2 + 0.25)
x = d/2.25 + 5
Equating:
d/2 = d/2.25 + 5
d = 90 miles
The distance to Johns's grandmother's house is 90 miles.

Sonya made a graph showing the first ten minutes of her drive to the movies.
A graph with time on the x-axis and speed on the y-axis. The graph increases, increases rapidly, and then remains constant.
Which description is the best interpretation of the graph?
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
Sonya backed out of her driveway at a constant speed and then accelerated until she reached the street where the movie was playing. She stopped the car.
Sonya drove down her driveway at a constant speed until she reached the street. She turned and drove down the street at a constant speed. Her car went slower as she drove up a hill. At the top of the hill she drove into the parking lot of the movie theater.
Sonya accelerated as she drove down her driveway. She accelerated on the street on her way to the highway entrance. She waited for a red light, then accelerated onto the highway.
Answer:
A
Step-by-step explanation:
A. because the first point shows her acceleration and you can see her speed increasing when she hits the second point, so we can say that see accelerated up the ramp and after it hits the third point her speed becomes constant all the way when she reached the highway

A parabola has vertex (4,3).If one x-intercept is 1, find the other x-intercept.ASAP!!!!!
Step-by-step explanation:
The x-intercept(s) of a quadratic function are equidistant from the vertex. (if any x-intercept exists)
The vertex has x-value 4. Since one of the x-intercepts is 1, the other must be 7.
(7 - 4 = 3, 4 - 1 = 3)

ashley is baking a cake shaped as a right triangle. Two of the angles are measurement of 5x and 10x. What is the value of x?
Answer:
A. 6
Step-by-step explanation:
Since, cake is of right triangled shape, so measure of its one angle would be 90° and the sum of the measures of the remaining two angles will also be equal 90°.
Therefore,
5x +10x = 90
15x = 90
x = 90/15
x = 6

Answer:
t = 4°
Step-by-step explanation:
As in any triangle, the sum of angles is 180°.
17t + 16t + 12t = 180°
45t = 180° . . . . . collect terms
t = (180/45)° . . . . divide by the coefficient of t
t = 4°

Oak Street and Elm Street run parallel to each other. When Main Street
intersects them, it forms interior 26, measuring 70°. What is the measure of
24?
Answer:
110°
Step-by-step explanation:
The consecutive interior angles theorem states that when two parallel lines are cut by a transversal, the pair of angles formed which lie inside the parallel lines on the same side of the transversal are known as consecutive interior angles. This consecutive interior angles are supplementary (that is add up to 180°).
Therefore:
∠4 and ∠6 are consecutive interior angles. Hence:
∠4 + ∠6 = 180° (sum of co-interior angles)
∠4 + 70 = 180
∠4 = 180 - 70
∠4 = 110°
Answer:
110°
