Answer:
Step-by-step explanation:
If the equations are true, they can be solved simultaneously.
Consider 2x-10y=-1 as Eq1 and 5x+6y=4 as Eq2
Multiplying Eq1 with 3 and Eq2 with 5 we get,
6x-30y=-3 -- Eq3 and 25x+30y=20 -- Eq4
Adding Eq3 and Eq4,
31x=17 Therefore, x=17/31
Plugin x=17/31 in Eq3,
6(17/31)-30y=-3 --- y=13/62
Plug In values of x and y in 7x-4y we get,
7(17/31)-4(13/62) = 3
So the value of 7x-4y = 3.
Answer: <em>~subtract 1/3 - 5/6 = 4/3 but tats a improper fraction so then you need to simplify and there is your answer 3/4 simple i hope this helped have a nice day (❁´◡`❁)~</em>
Step-by-step explanation:
if you ate 1/3 of a pie that is 5/6 how much pie is left?
The total amount Sam will pay in all will be $2,400,000
<h3>Simple interest </h3>
From the question, we are to determine the interest Sam pays in all
Using the simple interest formula,
I = PRT
From the given information,
P = $2,000,000
R = 5% = 0.05
T = 4
Putting the parameters into the formula,
I = $2000000 × 0.05 × 4
I = $400000
The interest Sam will pay is $400,000
The total amount Sam will pay in all will be $2,000,000 + $400,000
= $2,400,000
Hence, the total amount Sam will pay in all will be $2,400,000

Answer:
A and B
Step-by-step explanation:
Given
p -> Doubling the sides of a rectangle
q -> Area increases by factor of 4
From the question we understand that q depends on p.
This means that the original statement is option A which says p → q
The arrow from p to q indicates that if p is true then q is true.
Hence, option A is correct
Option B is also correct because it represents the inverse of (A) above.
I.e. if the sides of the triangle is not doubled, then the area won't increase by a factor of 4.
This in its actual sense represent negation or inverse statement.
Hence, options A and B answer the question while other options are incorrect.
Answer:
commutative property
Explanation:
This is known as the commutative property of addition (and multiplication).
An easy way to remember the property is that the two elements commute, or exchange places, or that one element commutes from one side of the operation to the other, like a commuter (passenger) on a commuter train.
a + b = b + a
