Answer:
The first number:11
The second number: 16
The third number: 64
Step-by-step explanation:
Let the first number be x
The second number be 5+x
The third number be 4(5+x)
The sum: x+5+x+4(5+x) =91
Open the brackets
x+5+x+20+4x=91
Arrange in like terms
x+x+4x+5+20=91
6x+25=91
6x=91-25
6x=66
Divde both sides by 6( the coefficient of x)
x=11
5+x=16
4(5+x) =64
B) y= 2(x + 5)
C) x - 3y = 0
D) x= y + 3
Answer:
C
Step-by-step explanation:
Direct variation is a special case of first order equations; in both cases, the input is multiplied by a constant which we call the "slope" or "constant of variation." However, no direct variation equation includes a constant ("y-intercept"). So, if a given equation does have a y-intersect, that equation does not represent direct variation; if it does NOT have a y-intercept, that equation represents direct variation.
A) involves a constant term, -2; NOT direct variation
B) involves a constant term, 10; NOT direct variation
C) Here 3y = x, or y = x/3, involves no constant term, so Does represent direct variation
D) involves a constant term -3; NOT direct variation
2/300 = 0.0067
2/300 x 100 = 0.67%
Answer:
39892 rounding to thousand is 40000.
Step-by-step explanation:
Given : Number 39892.
To find : Round 39892 to the nearest 1000 ?
Solution :
Round to nearest thousand is
1) If the hundred place is less than 5 then the thousand place remain same and rest became zero.
2) If the hundred place is greater than or equal to 5 then the thousand place added by 1 same and rest became zero.
In number, 39892 the thousand place number is 9.
The hundred place is 8 greater than 5.
So, The thousand place added by 1 and rest became zero.
As 9 by 1 it shift to ten thousand place so 3 became 4.
39892 rounding to thousand is 40000.
