Direct variation equation:
y = kx, where k is the coefficient of variationWe have y = 900, when x = 12, find the value of k:
900 = 12kk = 900/12k = 75The equation is:
y = 75xNow, find the value of y, when x = 4:
y = 75*4 = 300Given that a + b = 2 and that a + b2=6, prove that 2ab = -2. Find also the value of (a - b)?
Water flows through a pipe at a rate of 89 cups per second. Express this rate of flow in gallons per hour
Answer:
Step-by-step explanation:
that sucks
Answer:
Answer: 20025 gallons per hour
89 times 60= 5340 cups in one minute
5340 times 60= 320,400 cups in one hour
Convert 320,400 cups into gallons and you will get 20025.

Answer:17x 45=765 pounds
Step-by-step explanation:
All you have to do is multiply.
If each gorilla eats 45 pounds then you multiply amount of gorilla by pounds of food , in this case 17x 45
Can anyone help, im stuck
Answer:
The second one is right
Step-by-step explanation:
anyone help, im stuck
Answer:
The third one
Step-by-step explanation:
Since, 1 can be represented by x we can make an equation
2 can be represented y
and 4 can be represented by x
Since x + y = 180 and x + z = 180
y = z
Or 2 = 4

Two systems of equations are shown:
System A System B
3x + 2y = 3 −x − 14y = 1
−2x − 8y = −1 −2x − 8y = −1
Which of the following statements is correct about the two systems of equations?
A.)The value of x for System B will be one-third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A.
B.) The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.
C.) They will have the same solution because they represent the same lines when plotted on the coordinate axes.
D.)They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
I don't understand this question can someone help me with this please, please explain!! and thank you for the help!! If u dont know try your best. Please do it quick, please do all :D
Answer:
1. C) .4
2. B) 2 1/4
3. D) 3 5/8
Step-by-step explanation:
1. The question is asking what fraction (represented in decimal form) did Maria spend. To find this, divide 18/45 because Maria spent $18 of her $45. When you complete this calculation, you get .4
2. When you look at where the line ends, it's at the first quarter line after the 2, meaning that the line is 2 and one quarter or 2 1/4
3. 8 times 3 is 24, which is the closest multiple of 8 to 29. However, since there is still 5 left over (which still needs to be divided by 8) it would be represented by the mxed fraction.

which of these have a these has a sum of 15/6
35/9 + 35/5 or 15/2 + 15/4 or 3/8 + 34/16 or 2/3 + 1/16
3/8 + 34/16
15/6 can be simplified to 2 1/2
The answer for 3/8 + 34/16 can be simplified to 2 1/2
what is slope intercept form of
slope= -2, y-intercept= -5
slope= -1/4, y-intercept= 1
slope = 2, y-intercept= 0
Step-by-step explanation:
the slope intercept form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
so, we have the equations
y = -2x -5
y = (-1/4)x + 1
y = 2x
Jose has 8 2/3 cups of plaster of Paris powder. If Jose uses 5 3/5 cups of sculpture, how much plaster will he have left?
Answer:
3 1/15
Step-by-step explanation:
8 2/3 - 5 3/5
find the LCD(least Common denominator)
8 10/15 - 5 9/15 = 3 1/15
What is the length of the hypotenuse? If necessary, round to the nearest tenth.
Answer:
17
Step-by-step explanation:
Answer:
The hypotenuse is 17.
Step-by-step explanation:
a^2+b^2=c^2.
Let's plug in a and b.
15^2 + 8^2 = c^2
Simply.
225+64=c^2
Add.
289=c^2.
Square 289 and c^2 to cancel out the ^2.
17=c
The hypotenuse is 17.

if 10 litres of petrol can cost 650 calculate the cost of 15 Litres and 25 litres
Answer:
15 liters = 975
25 liters = 1625
Step-by-step explanation:
10 liters = 650
1 liter = 650/10 = 65
15 liters = 65 x 15 = 975
25 liters = 15 liters + 10 liters = 975 + 650 = 1625

Answer:
a = 45°
Step-by-step explanation:
In triangle PSR
PS = RS (Given)
angle SPR = angle SRP (isosceles triangle property)
Let angles SPR and SRP be x
Therefore, 90° + x + x = 180° (angle property)
=> 90° + 2x = 180°
=> 2x = 180° - 90° = 90°
=> 2x = 90°
=> x = 90° ÷ 2 = 45°
=> x = 45°
