Answer:
59.11
Step-by-step explanation:
Answer:
The required equation is given by,
2 + 
= 
Step-by-step explanation:
Let, each jar of Liam's paint contains x quarts of paint.
Then, Liam's solution contains,
2 + 
quarts of paint or,
2 + quarts of paint
and,
let, each jar of Evan's paint contains, y quarts of paint.
Then, Evan's solution contains,
quarts of paint or,
quarts of paint
now, according to the question,
the required equation is given by,
2 + =
2. Use the second equation (for y) to substitute into the first.
.. x +(2x +4) = 7
.. 3x +4 = 7 . . . . . collect terms
I know you can solve it from there. (x, y) = (1, 6)
3. Let "o" and "r" represent the numbers of orange fish and red fish, respectively.
.. o +r = 31 . . . . . there are 31 fish in a tank
.. o = 7 +r/2 . . . . there are 7 more orange fish than half the number of red fish
The second equation can be substituted into the first.
.. (7 +r/2) +r = 31
.. (3r/2) = 24 . . . . . . subtract 7
.. r = (2/3)*24 . . . . . .multiply by the inverse of the coefficient of r
I know you can solve it from there. (o, r) = (15, 16)
Answer:
v=5/48
Step-by-step explanation:
I first distributed or multiplied the outside times the inside and then I combined like terms. I got 29v-9=-19v (because of 5v-24v) and added 9 to both sides. Then I got 48v=5 and divided my 48 and the simplified form is 5/48. Hope this helps you!
Answer:
Step-by-step explanation:
Distributive property: a(b +c)=(a*b )+(a*c)
a) 2(y + 5x) = y*2 + 5x*2
= 2y + 10x
b) 0.4(x + 2) = x*0.4 + 2*0.4
= 0.4x + 0.8
