Which equations show a line that is parallel to the line y = -5/4x + 1?
select all that apply
1/2x+1/2x= x+1
Solution:
(The answer can be no solution and infinitely many solutions)
Answer:
No solution
Step-by-step explanation:
On the left side we have one half x plus one half x which equals x. On the right side we have x + 1. So the equation becomes x = x + 1. Subtracting x from both sides we get 0 = 1, which is false. Therefore there is no solution to this problem.

Next, we evaluate the expressions as follows
So, we have
ab + ac = ab + ac
(b + c)a = ab + ac
a(b + c) = ab + ac
ab + c = ab + c
See that all but the last expression have a value of ab + ac

Help please. I cant figure this one out.
Answer:
x =52
Step-by-step explanation:
The angles shown are same side interior angles, and when the lines are parallel, same side interior angles add to 180 degrees
< 1 + <2 = 180
x+23 + x+53 = 180
Combine like terms
2x+ 76 = 180
Subtract 76 from each side
2x+76-76 = 180 -76
2x = 104
Divide by 2
2x/2 = 104/2
x =52
Answer:
x = 52
Step-by-step explanation:
Angle 1 and angle 2 are on the same side, and on the inside of the interior. This means that when added together they = 180
We can set up an equation
x+23+x+53 = 180
Simplify: 2x + 76 = 180
Subtract 76 from both sides
2x = 104
Now divide by 2
x = 52

choose the equation that represents the line that passes through the point (6, −3) and has a slope of one half. (1 point)
The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.
The equation of a line is represented as,
y = mx + c equation1
x and y are the coordinates of the point from where the line is passing and m is the slope of the line.
As per the question the line is passing from the point (6, -3). This means value of x = 6 and that of y = -3. The slope of line is (1/2), means m = (1/2).
The slope of the line through the point (-1,6) can also be written as (y - 6)/(x - (-1)) = (y-6)/(x+1).
i.e., m = (y-6)/(x+1)
On equating both the values of m, we will get
(y-6)/(x+1) = 1/2
On simplifying, we get
2y - 12 = x +1
or 2y - x = 13
The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.

The speed of the plane and wind in km/hr is 187.5 and 37.5 respectively.
What is a linear equation ?A linear equation has highest degree of 1.
According to the given question a small plane flies for 3 hours to an airport 450 kilo meters away against a strong headwind. the plane then returns to its starting location flying with the wind, taking 2 hours.
Form these we can form two linear equations in two variables.
Assuming speed of the plane to be x km/hr and speed of wind to be y km/hr.
We know Distance = speed × time.
3( x - y) = 450. and 2( x + y) = 450.
3x - 3y = 450...(i) and 2x + 2y = 450...(ii)
multiplying eqn (i) by 2 and eqn (ii) by 3 and solving we get
x = 187.5 km/hr and y = 37.5 km/hr.

Answer:
Skip counting
Step-by-step explanation:
Skip counting is when you count at intervals of any number you like. If I were to skip count by seven, I would count 7, 14, 21, and so on. You can easily accomplish single-digit multiplication with this method. For example, suppose your teacher asks you to multiply 4 x 7 =. Simply count sevens four times, 7, 14, 21, and 28. 4 x 7 = 28 is the answer.
Go over the skip-counting list until you get to the halfway mark (3, 6, 9, 12, 15, and 18). Allow yourself to speak it out loud while pointing to the answers one by one with a finger or a pen. This engages many senses at the same time.

Kurt spent $96.39 over 414 months on movie streaming services. if he spent the same amount of money each month, how much money, in dollars, did kurt spend per month on movie streaming services?
Using proportions, it is found that Kurt spent $22.68 a month on movie streaming services.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, or operations such as multiplication and division.
These operations are used from the unit rates, as for example, when we have an amount over a period of time, the amount per unit of time is the total amount divided by the total time.
For this problem, we have that the important parameters are found as follows:
The total amount is of $96.39.The time is a mixed number, 4 and 1/4 months, hence it is of 4.25 months, as 4 + 1/4 = 4 + 0.25 = 4.25.Hence his monthly spending is given by the unit rate as follows:

Using the ratio given in the question,
Apples received by Fay are 72.Apples received by James are 40.Apples received by Sal are 48.What is Ratio?The relation between the quantities of two or more objects—referred to as a ratio—indicates how much of one object is contained in the other. The ratio formula can be used to represent a ratio as a fraction. The ratio formula is given as, for any two quantities, let's assume a and b.
a:b = a/b
Given that James, Fay and Sal share 160 apples.
Total number of apples = 160
Hence, apples received by James = 1/4(160)
= 40 apples
Remaining apples = 160 - 40 = 120 apples
It is also given that the remainder is shared by Fay and Sal in the ratio 3:2.
Hence, the total share will be 3+2=5
So, we can write that Fay's share will be 3/5 of total apples and Sal's share will be 2/5 of the total apples.
Fay's share = 3/5(120)
=3(24)
=72 apples
Sal's share = 2/5(120)
=2(24)
=48 apples
Therefore, the number of apples with Fay is 72.
