solve for p
Answer:
p = 3.6
Step-by-step explanation:
Our goal is to isolate P.
Let's start by adding 4 to each side:
8p = 28.8
Next, we will divide each side by 8:
p = 3.6

Use these graphs to solve the simultaneous equations 5x-9y = -46
y = -2x
Answer:
(-2, 4)
Step-by-step explanation:
In the first equation substitute -2x for y, obtaining: 5x - 9(-2x) = -46
Then 5x + 18x = -46, or 23x = -46, resulting in x = -2
Since y = -2x, y = -2(-2) = 4
The solution is (-2, 4)
The value of x coming is -2 and the value of y=4 by plotting the equations 5x-9y=-46 and y=-2x.
What is a equation?
A statement that the values of two mathematical expressions are equal.
How to plot graph of an equation?
First we have to find the values of x and y as we can see in the figure1.
By plotting these points we can make graph of both the equations and the intersection point will be the solution of these equations.
Blue line is the line of the equation 5x-9y=-46 and the green line is the line of the equation y+2x=0

Answer:
The first one would be m^30n^20p^30
And the second one would be a^2 / d^4
Step-by-step explanation:
For 1, you have to multiply the inner exponents by the outer one so you get (m^12n^8) times (m^18n^12p^30). Then you mutiply the two together, so you add the exponents, where you get m^30n^20p^30.
For 2, since you're dividing, you have to subtract the exponents so you get a^2d^-4, but since you shouldn't have the negative you turn it into a^2 / d^4

if the point x,y is on the y-axis which of the following is true x=0 y=0
Hi there!
Answer:
x=0
How it works:
In coordinate planes, x always goes first. Then the y comes next. If x is 0, and y is also zero, none of those would be in the y axis place...
If the x is in 0 and the y is 1,2,3,4,5.... then the y axis would be in the y axis and x would just stay the same...
If the x is 1, then the y would be 0 which means that there would be nothing in the y axis.
Therefore, the answer is x=0..

PLEASE HELP OR ELSE MOM WILL BE REALLY MAD!!!!! Two trains, one going from Boston to New York and the other going from New York to Boston, started their trips at exactly same time. Speed of the first train was 10 mph less than twice the speed of the second train.How far from Boston station to have the Met in two hours, if the total distance between cities along the railroad is 220 miles?
Answer:
140 mile
Step-by-step explanation:
[tex]d_{1} +d_{2} =220\\2(2x-10+x)=220\\x=40\\d_{1}=2*(2*40-10)=140mile[/tex]
While x is the speed of the second train.
The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.
SpeedSpeed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let a represent the speed of the first train. In two hours:
a = d₁/2
d₁ = 2a
a + 10 = d₂/2
d₂ = 2a + 20
d₁ + d₂ = 220
2a + 2a + 20 = 220
4a = 200
a = 50 miles per hour
The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.

You have $3.10 in dimes and quarters.You have 3 more dimes than quarters. write an equation that relates the number of coins and have any equation for the value of the coins.how many of each kind of coin do you have?
Answer:
y=Q+3D
Step-by-step explanation:
the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,
0.10x + 0.25y = 3.10 ...1
x = y + 3 ...2
From equations 1 and 2, then we have
0.10(y + 3) + 0.25y = 3.10
0.10y + 0.30 + 0.25y = 3.10
0.35y = 2.8
y = 8
Then the value of 'x' is given as,
x = 8 + 3
x = 11
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
