61/28+a=19/4a-11/7
Clear the fraction by multiplying by the lcd. The lcd for 28, 4, and 7 is 28 (Since 7 and 4 are factors of 28)
(6/28)·28=6/1 or 6
a·28=28a
(19/4)·28=19·7=133
(11/7)·28=11·4=44
6+28a=133a-44
Combine like terms:
6=105a-44
50=105a
Isolate the a: 50/105÷5=10/21
a=10/21 :)
The correlation coefficient for blood pressure and amount of vegetables eaten which is a negative number (-0.7) suggests that they are in inverse relation. Eating more vegetable should lower the blood pressure. In the same manner, not eating vegetables would likely cause high blood pressure.
Step-by-step explanation:
I would say there are 7 oranges out of ten, ummm and
7/10 divided by 9/11
=77/90

Parallel lines share the same slope. y=3x+7 has a slope of 3, so that is the slope of the parallel line. Then use y=mx+b an plug in (2,4).
y=3x+b
4=3(2)+b
4=6+b
b=-2
So the equation is y=3x-2
Answer:
Step-by-step explanation:
Let L = Lucy, C = Carol and A = Arita , x = Total amount of marbles
Lucy shares 1/3 with Carol and keeps 1/4 for herself.
This means that Carol has 1/3 of the total amount of marbles, Lucy has 1/4 of the total amount of marbles.
C = 1/3x
L = 1/4x
We are also told that Carol has 7 more marbles than Lucy
C = L + 7
Since C = 1/3x and L = 1/4x you can sub these into the above equation and you get:
1/3x = 1/4x + 7
Subtract 1/4x from both sides
1/3x - 1/4x = 7
1/12x = 7
Multiply both sides by 12 to find x.
x = 7 times 12 = 84 (Total amount of marbles = 84)
Amrita gets the remaining number of marbles.
A = x - C - L
A = 84 - 1/3 (84) - 1/4 (84)
A = 35
