Eight hundred fifty and 05/100
Answer:
T1he values for x and y of the equations is y = 11, and x = -19/5.
Step-by-step explanation:
To solve this question, we need to rearrange the expression:
5x+4y=25 - (5x+2y=3)
Look, if we subtract one equation to the other, then:
5x+4y=25 [1]
-(5x+2y=3) [2]
Which is the same as:
5x+4y=25
-5x-2y=-3
Subtract them:
5x+4y=25
-5x-2y=-3
---------------
2y =22
y = 22/2 = 11
Then, y = 11.
To find x, we can substitute<em> y</em> in either equation [1] or [2].
Let us use [1]
5x+4y=25
5x+4(11)=25
5x+44=25
5x=25-44
5x=-19
x = -19/5
Then, the values for x and y of the equations is y = 11, and x = -19/5.
In the problem 62x45, what are the
partial products?
To acquire the possible partial
products we can just multiply the two numbers to produce the possible numbers
at hand.

1.
</span>62 x 45 = 2790</span>

2.
</span>45 x 62 = 2790</span>
Same outcome which is explained by the comutative property of multiplication.
Since a number is divisible by 2 and 3 and 5 it can be written as 2*3*5*x=num where x is a natural number
a number is only divisible by a number if they share the same prime divisors so the numbers that will always be divisible by that number are:2,3,5,2*3:6,2*5:10,3*5:15,2*3*5:30 C)30 which is the correct answer
