Answer:
x = 7
y = -3
Step-by-step explanation:
x + y = 4 (Multiply this by 9)
-9x + 7y = -84
9x + 9y = 36
-9x + 7y = -84
16y = -48
y = -3
x + y = 4
x - 3 = 4
x = 7
solve the equation. -4(7x + 8) = 192
The ratio of red apples to green apples on a farm is 3:1. If there are 180 red apples on the farm, how many green apples are there?
Answer:
There is 60 green apples
Step-by-step explanation:
Since there is 1 green apple for every three red apples you could divide 180 by 3 which would equal 60 so there is 60 green apples.
Latisha owns two spas, one in Pine township and the other in Adams township. Each spa offers a 30-minute face, head, and neck massage to reduce muscle tension. However, therapists first ask each patient questions about their type of tension and stop about five minutes before the end of the 30 minutes to have time to prepare for the next patient. The number of minutes each therapist massages the patients at both spas is approximately Normally distributed, with the Pine spa having a mean of 22.6 minutes and a standard deviation of 1.7 minutes and the Adams spa having a mean of 21.0 minutes and a standard deviation of 2.8 minutes. If Latisha randomly selects 8 massage times from Pine and 9 from Adams, what is the probability that the mean time for Pine is longer than the mean time for Adams? 0.0748 0.7157 0.8264 0.9252

Supplementary means the angels add up to 180 degrees. So 95 + ? = 180. The ? is equal to 85, but how do you get it. Well we know 5x means to multiply a # by 5. So 17 x 5 = 85. So x = 17. Hope this helps!
Answer:
17
Step-by-step explanation:
5 x 17 = 85 right?
95 + 85 = 180.

A fire ranger on a 150-ft-tall tower spots a fire at a 30° angle of depression. How
many feet away from the tower is the fire to the nearest tenth?
Answer:
259.8ft
Step-by-step explanation:
The distance from the tower to the fire to the nearest tenth is 260 feet.
Let the adjacent side be a.Given the following data:
Angle of depression = 30°.Opposite side = 150 feet.To determine how far away (in feet) from the tower is the fire to the nearest tenth:
How to apply trigonometric function.In order to solve this exercise, we would form a mental image of the scenario being described. The height of the tower is the opposite side while the distance from the tower to the fire is the adjacent side.
Next, we would apply the Tan trigonometric function:
[tex]Tan \theta = \frac{Opp}{Adj} \\\\Tan 30=\frac{150}{a} \\\\a=\frac{150}{Tan 30} \\\\a=\frac{150}{0.5774}[/tex]
a = 259.79 ≈ 260 feet.

Answer:
4/5x+2/5 = y
Step-by-step explanation:
(-3, -2) & (2,2) - given points
1. Find Slope
2-(-2) / 2-(-3) = 4/5
m=4/5
2. plug in points to find b
4/5(x)+b=y : mx+b=y (slope intercept form)
4/5(2)+b=2
8/5+b=2
2 - 8/5 = b
10/5 - 8/5 = b
b=2/5
Therefore: 4/5x + 2/5 = y

Answer:
50
Step-by-step explanation:
What I did first is I converted 72% into a decimal (I work better with decimals), giving me 0.72. Then I solved the equation 36/0.72=x.
x = 50
Answer:
50 questionsStep-by-step explanation:
Let the number of questions be x.
We have:
72% of x is 36.Build an equation and solve for x:

Step-by-step explanation:
what is the ordered pair solution for y>= 1/3x+4
Answer:
Step-by-step explanation:
y > (1/3)x + 4 has an infinite number of solutions. Draw a dashed line representing y = (1/3)x + 4 and then pick points at random on either side of this line. For example, pick (1, 6). Substitute 1 for x in y > (1/3)x + 4 and 6 for y. Is the resulting inequality true? Is 6 > (1/3)(1) + 4 true? YES. So we know that (1, 6) is a solution of y > (1/3)x + 4. Because (1, 6) lies ABOVE the line y = (1/3)x + 4, we can conclude that all points abovve this line are solutions.

Opposite angles are congruent , so
9x - 5 = 103 (add 5 to both sides )
9x = 108 ( divide both sides by 9 )
x = 12
Consecutive angles are supplementary, sum to 180° then
7y + 103 = 180 ( subtract 103 from 180 )
7y = 77 ( divide both sides by 7 )
y = 11
------------------------------------------------------------------
(4)
Opposite sides are congruent, so
3x = 36 ( divide both sides by 3 )
x = 12
and
5y = 45 ( divide both sides by 5 )
y = 9

Answer:
the last option -5 ≤ x ≤ 3
Step-by-step explanation:
Because the line there means what x can be so x has to be grater than -5 but less then 3 because the line does not go over 3.
Answer:
- 5 ≤ x ≤ 3.
Step-by-step explanation:
The range of the required values is in the bold line.
The solid circles at the end of the bold line mean the values at these points are included in the inequality.
So it is:- x is greater than or equal to -5 and less than or equal to 3.
That is - 5 ≤ x ≤ 3.

Parker and Eugene sold tickets for the school play.They each need to sell 35 tickets To receive a prize. On day one sold 23 tickets on day two sold 25 tickets and on day three the sold 35 tickets if they want to equally share the number of tickets between them how many ticket sales will each boy have
Answer: 41.5
Step-by-step explanation:
Number of tickets sold on day one = 23
Number of tickets sold on day two = 25
Number of tickets sold on day three = 35
Total tickets sold = 23 + 25 + 35 = 83
Since they want to share it equally, each boy will have:
= 83/2
= 41.5
A research group is comparing the learning outcomes of students who are taught a lesson using four different teaching techniques. There are 75 students in the school who can participate in the experiment. Using a table of random digits, the researchers will randomly place the students into five equally sized treatment groups suitable for comparison, four of which will receive a different teaching technique and one of which will remain a control group.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, 3, 4, or 5. Assign the students to the treatment groups based on their label.
B Select a student, and identify the first digit reading from left to right on a random number table. If the first digit is 1 or 2, assign that student to the technique 1 group. Similarly, digits 3 or 4, 5 or 6, 7or 8, and 9 or 0 go with the technique 2, technique 3, technique 4, and control groups, respectively. Repeat this process for each student.
C Number each student from 1 to 75. Reading the numbers from left to right on a random number table, identify 60 unique numbers from 1 to 75. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
D Number each student from 00 to 74. Reading the numbers from left to right on a table of random numbers and looking at two digits at a time, identify 60 unique two-digit numbers from 00 to 74. Assign the students whose labels are the first 15 numbers to the technique 1 group. Assign the students whose labels are the second 15 numbers to the technique 2 group. Repeat this process two more times to assign the technique 3 and technique 4 groups. Finally, assign the remaining students to the control group.
