If one serving takes 3/8 of a cup and she wants two servings, just multiply 3/8 by 2.
2 * (3/8) = 6/8 or 3/4 of a cup.
Answer:
5 months
Step-by-step explanation:
Let n be the number of months.
1. Triax offers a new phone for $50 and a limited service for a monthly fee of $40. Then the phone will cost
$50+$40·n.
2. Cellular offers a new phone and unlimited service for a monthly fee of $50. Then the phone will cost
$50·n.
Equate these to amounts:
50+40n=50n,
50=50n-40n,
50=10n,
10n=50,
n=50:10,
n=5.
These two lines are congruent (the same) so we can set them equal to each other and solve.
5x-4=3x+6
The first thing we need to do is subtract 3x from both sides leaving us with 2x-4=6
Now we can add 4 to both sides leaving us with 2x=2
Now we need to divide both sides by 2 to get x alone.
Giving us our final answer of x=1
Answer: angle y is 50°
Step-by-step explanation:
t + 2t - 30 = 90
3t -30 = 90
3t = 90+30
t = 120/3 = 40 = angle X
Angle y = 2t-30
y = 2*40-30
=80-30 = 50
Answer:
$400
Step-by-step explanation:
To solve this, we need to understand how one reaches the final price. The general formula for final price (with tax) is:
t(c) = p x (1+t)
t(c) is total cost
p is price
t is tax rate as a decimal
To find p, we need to create a new formula. Since we have the total cost ($408) and the tax rate (2% or .02), we can divide the total cost by 1 + the tax rate to solve for the price:
t(c) / (1+t) = p
408 / (1+.02) = $400
I hope this helps!
