Answer:(x+7)(x+8)
Step-by-step explanation:
Santosh spent $200, before tax, on a DVD player and DVDs. The player cost $120, new DVDs cost $15 and used DVDs cost $5. Santosh purchased the same number of new and uses DVDs. Write and solve an equation to find the number of each type of DVD Santosh purchased.
Answer:
Santosh purchased 4 new and 4 used DVDs.
Step-by-step explanation:
From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:
15x+5y=80, where:
x refers to the number of new DVDs
y refers to the number of used DVDs
Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:
15x+5x=80
20x=80
x=80/20
x=4
According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Step-by-step explanation:
Answer:
A. 51
Step-by-step explanation:
Subtract 25 from each side to isolate the variable
it would look like this:

what is the lcm of 6 and 8
Answer:
The LCM, or least common multiple, of 6 and 8 is 24.
Answer: 2
Step-by-step explanation:
First you find the multiples of 6 and 8 then you do this.
2x3
2x2x2x2x2x4
Then you circle the 2’s and so the lcm on 6 of six and 8 is 2.

Two angles in a triangle measure 102° and 670. What is the measure of the third angle?
0 110
0789
1139
O 169°
Step-by-step explanation:
step 1. wow! 670° I think you mean 67°
step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle
step 3. x + 102 + 67 = 180
step 4. x + 169 = 180
step 5. x = 11°.
Lily wants to ride her bicycle 43 miles this week. She has already ridden 16 miles. If she rides for 6 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
43-16=miles left to go. divide that by the 6 days left.
43-16= 27 miles.
27÷6= 4.5 miles per day
Answer:
4 1/2 miles
Step-by-step explanation:
43 - 16 = 27 miles remaining
27/6 = 4 3/6 or 4 1/2

Answer:
x=12 y=6 m(ABC)=102 m(BCD)=78 m(DAB)=78
Step-by-step explanation:
alright mate so lets start with the properties of parallelogram:
Opposite angles are equal Sum of any two adjacent angles is 180degree(there are more but we will use those here)
so lets start with 1st property for help:m(BCD) is opposite angle for m(DAB) so those equations should be equal each other and this will give us a hint
[tex]6x+y=4x+5y\\2x=4y\\x=2y[/tex] i just changed the places of x to be in one place and s same for y then divided both sides by 2
Now lets use the 2nd property (sum of two adjacent angles is 180)m(ABC) is adjacent to m(BCD) so
[tex](7x+3y)+(4x+5y)=180[/tex] add x to x and y to y it will be
[tex]11x+8y=180\\[/tex]
Now we going to use the first one x=2y in this equation so we can deal with one variablereplace x with 2y so 11x will be 22y
[tex]22y+8y=180\\30y=180\\y=6[/tex] added the y to y and then divided both sides by 30
[tex]x=2y \\x=2*6=12[/tex]
now we got x and y
then lets start to substitute every x and y in the equations
[tex]7x+3y\\7*12+3*6=102\\[/tex] [tex]4x+5y\\4*12+5*6=78[/tex]3.[tex]6x+y\\6*12+6=78[/tex]
now we got everthing hope i helped you sorry also for being late it toook alot to type it so you can understand
Mrs. Tirado picked 5/6 pounds of lettuce from her garden. Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado. How much lettuce did they pick altogether?
Step-by-step explanation:
Total amount of lettuce = x pounds
Mrs. Tirado picked 5/6 pounds of lettuce from her garden.
5 / 6 * Total amount = 5/6 x
Mrs. Rampulla picked 2/3 less pounds than Mrs. Tirado.
Mrs. Rampulla = 2/3 (Mrs. Tirado) = 2/3 (5/6 x)
Mrs. Rampulla = 5/9 x
How much lettuce did they pick altogether?
Mrs. Rampulla + Mrs. Tirado
5/9 x + 5/6 x
(25/18) x pounds

Given:
Total number of students: T = 147
Number of students taking math : M = 95
Number of students taking science : S = 73
Number of students taking both math and science = 52
To find:
The theoretical probability of randomly choosing a student who is taking math.
Solution:
It is given that,
Total number of students (T) = 147
Number of students taking math (M) = 95
So, he theoretical probability of randomly choosing a student who is taking math is:
[tex]P(M)=\dfrac{\text{Number of students taking math}}{\text{Total number of students}}\times 100\%[/tex]
[tex]P(M)=\dfrac{95}{147}\times 100\%[/tex]
[tex]P(M)=64.62585\%[/tex]
[tex]P(M)\approx 64.6\%[/tex]
64.6% is the theoretical probability of randomly choosing a student who is taking math.
Hence, option C is correct.

Find the value of x that makes Triangle DEF~ triangle XYZ.
Answer:
x = 4
Step-by-step explanation:
DE / XY = EF / YZ
5 / 10 = 2x-1 / 14
cross-multiply:
10(2x-1) = 14(5)
20x - 10 = 70
20x = 80
x = 4
The ratio of their corresponding side will remain constant. Then the value of x is 4.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
The two triangles are ΔDEF and ΔXYZ.
It is given that the ΔDEF and ΔXYZ are similar.
Then the ratio of their corresponding side will remain constant. That is
[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]
From the first two, we have
[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]
On simplifying, we have the value of x
x = 4

Race organizers want to survey the participating runners on the difficulty of the running course. Which of the following most effectively uses cluster sampling?
Separate the runners into men and women, then randomly select 20 men and 20 women.
Organize the runners into groups (elite runners, fast runners, moderate runners, and walkers). Randomly select a group, and survey all the runners in that group.
Put the same number of marbles as runners into a bag, with 20 of the marbles being red. Have each runner select a marble from a bag at the finish line. If they choose a red marble, they take the survey.
Place the runners into groups based on the seconds part of their finishing time (0:00–0:05, 0:06–0:10, etc.). Randomly select 2 of these groups, and survey every runner within the chosen groups.
