Solve the given inequality and graph the solution on a number line. -x/2 + 3/2 < 5/2
Answer:
x > −2
Step-by-step explanation:
You need to isolate the variable. You can do this by first subtracting 3/2 from both sides of the inequality sign.
You will get -x/2 < 2/2.
Next, since x is being divided by -2, you will multiply it by -2 to undo it. Do this to both sides.
Note that when multiplying or dividing by a negative you will flip the inequality sign. '<' becomes '>' and '>' becomes '<'.
You will get x > -2.
The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the
cube 30 times, you would expect to get a 2 around 5 times (1/6 · 30 = 5).
You simulate 30 rolls. How many 2s would make you question your model?
A. 14
B. 5
C. 2.
D. 8
Answer: a
Step-by-step explanation:
If a cube is rolled by 30 times then 5 times 2s will make the question the model.
What is probability?Probability is the occurrence of any event or how likely an event can happen.
Mathematically probability = the number of desired outputs by the number of the possible outcomes.
In the number cube, there are six faces above each of them written one to six later.
The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.
Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.
If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.
So by 5 times, 2s will make the question model.

If the slope is -3 and (1, 2) is a point on the line, what is the equation of the line?
Answer: y=-3x+5
Step-by-step explanation:
First write in point slope form, y-y1=m(x-x1) which is y-2=-3(x-1). Then distribute the -3 and add the negative 2 to the other side to solve for y.
Solve for x. Round to the nearest tenth.

victor are 60 de lei si merge la florarie pentru a-i cumpara mamei sale un buchet de flori. daca ar cumpara 9 garoafe si 4 trandafiri, ar plati 47 de lei. daca ar cumpara doar trandafiri, toti banii i-ar ajunge pentru 12 bucati. insa el cumpara 13 flori (garoafe si trandafiri) si ramane cu 5 lei rest, cate garoafe si cati trandafiri a cumparat victor?
Answer:
Număr de trandafiri = x = 5 trandafiri
Numărul este garoafe = y = 8 garoafe
Step-by-step explanation:
Pasul 1
Să reprezentăm:
Costul garoafelor = c
Costul trandafirilor = r
Victor are 60 de lei și merge la florărie să-i cumpere mamei sale un buchet de flori.
Dacă ar cumpăra 9 garoafe și 4 trandafiri, ar plăti 47 de lei.
Prin urmare,
9c + 4r = 47 ..... Ecuația 1
Dacă ar cumpăra doar trandafiri, toți banii ar fi suficienți pentru 12 bucăți.
Prin urmare,
12 trandafiri = 60 lei
1 trandafir = r lei
Cross Multiply
12r = 60 lei
r = 60 lei / 12
r = 5 lei
1 trandafir costă 5 lei
Înlocuim 5 cu r în ecuația 1
9c + 4 × 5 = 47
9c + 20 = 47
Colectează ca termeni
9c = 47 - 20
9c = 27
c = 27/9
c = 3 lei
Costul unei garoafe este de 3 lei
Pasul 2
Dar cumpără 13 flori (garoafe și trandafiri) și rămâne cu 5 lei rămași,
60 lei - 5 lei = 55 lei
Asta înseamnă că a cheltuit 55 de lei pe 13 flori.
Lasă
Număr de trandafiri = x
Numărul este garoafe = y
x + y = 13 ......... Ecuația 1
x = 13 - y
Din moment ce, Costul unei garoafe = 3 lei și 1 trandafir = 5 lei
3x + 5y = 55 ...... Ecuația 2
Înlocuim 13 - y cu x în ecuația 2
3x + 5y = 55
3 (13 - y) + 5y = 55
39 - 3y + 5y = 55
Colectează ca termeni
- 3y + 5y = 55 - 39
2y = 16
y = 16/2
y = 8
Rezolvarea pentru x
x = 13 - y
x = 13 - 8
x = 5
Prin urmare:
Număr de trandafiri = x = 5 trandafiri
Numărul este garoafe = y = 8 garoafe
What is the slope of the line that passes through the points (-2,2) and (7,3)
Answer:
Step-by-step explanation:
Given points
let ( x1, y1 ) = ( - 2 , 2) and (x2 , y2 ) = (7, 3)
slope of the line (m)
= ( y2 - y1) / (x2 - x1)
= ( 3 -2 ) / ( 7 + 2)
= 1 / 9

Sal is tiling his entryway. The floor plan is drawn on a unit grid. Each unit length represents 1 foot. Tile costs $1.55 per square foot. How much will Sal pay to tile his entryway? Round your answer to the nearest cent. (hundredths place)
Answer:
He'll pay $110.25
Step-by-step explanation:
To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.
Area of trapezoid = (7 + 4)/2 x 6
Area of trapezoid = 33 sq ft
Area of parallelogram = 4 x 4
Area of parallelogram = 16 sq ft
Total area = 49 sq ft
Cost = 2.25 x 49
Cost = $110.25

Find the measure of each interior angle and each exterior angle of a regular 90-gon.
Answer:
Interior angle
176 degrees
Exterior
4 degrees
Step-by-step explanation:
Exterior angle
For any polygon, the measure of the total exterior angle is 360
To get the individual exterior angle, we divide the total by n, which is the number of sides, 90 in this case
We have this as;
360/90 = 4
Interior
To get the measure of each interior angle, we use the formula below;
[(n-2)180]/n
n in this case is 90
So we have
[(90-2)180]/90
= (88 * 180)/90
= 2 * 88 = 176
help please!! ill mark brainliest
Answer:
∠ B = 54°
Step-by-step explanation:
The angles are supplementary, that is they sum to 180° , then
7x + 14 + 5x - 26 = 180 , that is
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Then
∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°

Sam is needing to make copies of a flyer for his new business. Store W charges $5 for unlimited copies and store Z charges $0.20 per copy and $2 for using the machine.
How many copies makes both stores cost the same amounts?
Answer:
I believe it would be 15 copies.
Step-by-step explanation:
Store W gives you unlimited copies for 5 dollars, so the number of copies doesn't matter for store W, they do not affect the cost. So, you will have to find how many copies from store Z will cost 5 dollars. Now, it tells you store Z charges 2 dollars for the use of the machine, so you can go ahead and subtract 2 from 5 (total amount to make it equal). That being done leaves you with 3 dollars for the copies themselves, it tells you each copy costs $.20. So, now all you have to do is divide 3 by 0.20, which gives you 15.
