ANSWER
EXPLANATION
Given information
The sum of the two numbers is 76
The larger number is 16 more than 2 times the smaller number
Let the two numbers be x and y
x ----> Larger number
y ----> smaller number
To find the value of x and y, follow the steps the below
Step 1: Write the algebraic expressions for the statement given
The sum of the two numbers is 72
Mathematically, this can be expressed as
Also, the larger number is 16 more than twice
Answer:
x=vel of d
y=vel oh h
t1=time taken by d
t2=time taken by h
we have 4t1=5t2..............(1)
also
3xt1=4yt2....................(2)
comparing 1 and 2
x/y=16/15
Step-by-step explanation:
Answer:
(A, B) = (-3, -129).
Step-by-step explanation:
First convert the first equation to slop-intercept form:
x + 5y = 7
5y = -x + 7
y = -0.2x + 1.4
The slope is -0.2 so the slope of the line perpendicular to this line has slope
-1/ -0.2 = 5.
Now, converting the second equation to slope-intercept form:
15x + Ay = B
Ay = -15x + B
y = (-15/A)x + B/A
So the slope -15/A = 5 so A = -3.
So y = 5x + B/-3
Substituting the point (-8, 3)
3 = 5(-8) + B/-3
B/-3 = 43
B = - 129.
The answer comes out to be X= -2
