Christy spent 25 of her money on a shirt. She has $21.75 left. How much did she spend on the shirt?
A. $8.70
B. $7.25
C. $14.50
D. $29
Christ spent a total amount of $ 14.50 on the shirt.
Finding the amount spent on the shirt
Here we use the linear equation concept to solve the problem.
Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.
Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below
Here we have
Christy spent 2/5 of her money on a shirt.
She has $21.75 left
Let 'x' be the amount that Christy has
From the data,
Christy spent 2/5 of her money on a shirt.
Amount spent by Christy = 2/5 of x = 2x/5
Remaining amount = x - 2x/5
From the data,
Chrisy is left with $ 21.75
=> x - 2x/5 = 21.75
=> 3x/5 = 21.75
=> 3x = 108.75
=> x = 36.25
Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50
Therefore,
Christ spent a total amount of $ 14.50 on the shirt.

9 ounces = how many pounds? in fraction form
Answer:
9/16 pounds
Step-by-step explanation:
1 pound = 16 ounces
With this information, we have make a proportion to find the number of pounds 9 ounces is
Let p = the number of pounds
16/1 = 9/p
Multiply both sides by 1 to get
16 = 9/p
Multiply both sides by p
16p = 9
Divide both sides by 16
p = 9/16
This fraction is in its simplest form and can't be simplified any more.

Which is the graph of y= -x-3?
Answer:
Graph a
Step-by-step explanation:
Answer:
the answer is A
Step-by-step explanation:
to start, I would use the slope intercept, in this case -3 which lets you know the slope meets the y axis at (0,-3) since you have that point, you count with the slope.
now slope is rise over run, therefore, it would be y over x and since the y in this case is 3, you'd go up three from your point. since x is 4, you'd go right four units from where you are. since A is the only graph that follows that, A would be correct.

A car and a motorcycle leave the city at the same time and drive to a lake that is 120 km away. The speed of the motorcycle is 20 km per hour greater than the speed of the car, so the motorcycle arrives at the lake 1 hour before the car. Find the speed of the car and the speed of the motorcycle. Plz answer fast!!
Answer:
40 km/h and 60 km/hStep-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
Time:
120/x = 120/(x + 20) + 1120(x + 20) = 120x + x(x +20)120x + 2400 = 120x + x² + 20xx² + 20x = 2400 x² + 2*10x + 10² = 2500(x + 10)² = 50²x + 10 = 50x = 40Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h

Un elev a depus la banca suma de 250 lei. Știind ca banca oferă dobânda anuala de 1%,iar stația impozitează dobânda cu 16%,aflati ce suma va avea elevul după un an de depunere.
Răspuns:
292,50
Explicație pas cu pas:
Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17
Suma principală depusă, P = 250
Suma totală, A după 1 an poate fi calculată astfel:
A = P (1 + rt)
Unde ; r = rata dobânzii; t = timp
A = 250 (1 + (0,17 * 1))
A = 250 (1,17)
A = 292,5

The ratio of lemons to lime in a punch is 6:4. If there are 35 fruit in the punch, how many of them are lemons?
Answer:
21 lemons
Step-by-step explanation:
If the ratio is 6:4, the ratio is also equal to 3:2. This means, for every 3 lemons, there are two limes.
So, if there are 35 lemons and limes in total, we would have 21 lemons and 14 limes.

Answer:
76 feet (Just put 76 in the answer box)
Step-by-step explanation:
Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.
2(3.5) + 2(4.5)
The two products would be 7 and 9 respectively.
7 + 9 = 16 feet of fencing for 1 rabbit pen.
We have 2 pens, so multiply 16 by 2.
The rabbit pens need 32 feet of fencing.
(Alternatively you could have done 2(2(3.5 + 4.5)).
2(2(8))
2(16)
32 ft of fencing (rabbit pens))
Now, add 12 and 10. Then multiply that by 2.
2(12 + 10)
2(22)
The garden needs 44 feet of fencing.
Now add 32 and 44 to get the total amount of fencing needed.
32 + 44
The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)
What are the values of a and b, and what is an equation for the line?
Answer:
a = 1, b = 6
Step-by-step explanation:
slope of line = (5-2) / (12-3) = 3/9 = 1/3
(3-2) / (b-3) = 1/3
b-3 = 3 b = 6
(2-a) / (3-0) = 1/3
2-a = 1 a = 1
