<span>part A:
Let
t = total the liquid in the bottle including lemon juice and water
so t = lemon juice + water ( w = water, l = lemon juice) so t = l + w
but the bottle has 1 liter of water. and <span>60% lemon juice
</span>contains 60% lemon juice = 0.6, so l = 0.6t and w(water ) = 1 liter
t = l + w
substitute l = 0.6t and w = 1 into t = l + w
now you have equation
t = 0.6t + 1
part B:
from part A, you have equation t = 0.6t +1
solve for t
t = 0.6t +1
subtract 0.6t on both sides
t - 0.6t = 0.6t - 0.6t + 1
simplify
0.4t = 1
divide both sides by 0.4
0.4t/0.4 = 1/ 0.4
simplify
t = 2.5
2.5 liters is total including lemon juice and water
2.5 - 1(1 liter of water) = 1.5 <span>1 liter of lemon juice</span></span>
Answer:
8
Step-by-step explanation:
It would be 3/17 hope this helped and hope it's right
Y = x² + 2x - 8
which two numbers add up to 2 and multiply to -8?
-2 and 4
so rewrite the expression using the above;
(x - 2)(x + 4)
x = 2, -4
so the zeros are 2 and -4.
hope this helps, God bless!
Answer:
7
Step-by-step explanation:
Those are alternate interior angles. Alternate interior angles are the ones that happen at different intersections along the transversal but on opposite sides while inside the lines the transversal goes through. If these lines are parallel, then the alternate interior angles are congruent. Same thing the other way around. Alternate interior angles being congruent implies those lines are parallel.
So we are looking to solve:
3x-2=2x+5
Subtract 2d on both sides:
x-2=5
Add 2 on both sides:
x=7
