Answer:
x=10 and y=15
Step-by-step explanation:
1: Plug y into the equation
y=2x-5
5x-4(2x-5)=-10
2: Solve for x
-3x=-30
<em><u>x=10</u></em>
3: Plug x into the other equation
x=10
y=2(10)-5
4: Solve for y
<u><em>y=15</em></u>

Answer:
39062.5
Step-by-step explanation:
-2+-10+-50+-250
-10/2=-250/-50 = 5
sum of the geometric sequence
Sₙ = arⁿ⁻¹ /r-1 a=-2, r = 5
S₈ = -2(5)⁸⁻¹/(5-1) = 2(5⁷)/4 = 2(78125)/4= 78125/2= 39062.5
S₈=39062.5
Answer:
Expression B: 0.8p
Expression D: p - 0.2p
Step-by-step explanation:
The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item.
Expression A: 0.2p
Expression B: 0.8p
Expression C:1 - 0.2p
Expression D: p - 0.2p
Expression E: p - 0.8p
Which two expressions each represent the sale price of the item?
Regular price of the item = $p
Sale price = 20% off regular price
Sale price = $p - 20% of p
= p - 20/100 * p
= p - 0.2 * p
= p - 0.2p
= p(1 - 0.2)
= p(0.8)
= 0.8p
The sale price is represented by the following expressions
Expression B: 0.8p
Expression D: p - 0.2p
5 pennies = .05
5 dimes= .50
5 quarters= $1.25
Add those together and get:
1.80
Subtract 1.80 from 2.06
And you’ll get:
.26
Meaning there is a quarter and a penny left.
