Answer: 1/2
Step-by-step explanation:
30x + 18 = 35-4x
collecting like terms
30x + 4x = 35-18
34x = 17
divide both sides by 34
34x/34 = 17/34
x = 1/2
Idk if this wil help but...
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.
Distance covered by Matthew in 30 minutes = 30X
Distance covered by Lowe in 30 minutes = 30(3X)= 90X
90X = 30X + 1200 X = 20 yards/min
Let speed of Matthew be X yards/min Speed of Lowe = 3X yards/min.
Distance covered by Matthew in 30 minutes = 30X
Distance covered by Lowe in 30 minutes = 30(3X)= 90X
90X = 30X + 1200 X = 20 yards/min
You would find the solution of this question by finding what plus 4 times its self is 50.clay has 40 red apples because he has 10 green 10*4=40 and 10+40=50.
Answer:
d. 52.5 million cases
Step-by-step explanation:
from the data output in the question, we have the regression equation to be
log y = -151.281 + 0.076577x
y is the number of hiv cases which is in millions
x is the year of the hiv case
x = 1998
we put the value of x in the regression equation
log y = -151.281 + 0.076577(1998)
log y = -151.281 + 153.000846
log y = 1.719846
since the result is in log form,
y = 52.5 million cases
we have point (-6, - 1)
Now we will put these points in each equation,
y = 4x +23
put x = -6 and y = -1
-1 = 4 (-6) +23
-1 = -24 + 23
-1 = -1
LHS = RHS, so this equation has (-6 , -1) as solution.
y = 6x
put x = -6 and y = -1
-1 = 6 (-6)
-1 not= -36
LHS is not equal RHS, so (-6 , -1) is not a solution for that equation,
y = 3x - 5
put x = -6 and y = -1
-1 = 3 (-6) - 5
-1 = -18 - 5
-1 not= -23
LHS is not equal RHS, so (-6 , -1) is not a solution for that equation,
y= 1/6 x
put x = -6 and y = -1
-1 = -6/6
-1 = -1
LHS = RHS, so (-6 , -1) is a solution for that equation,
