Answer:
X=2, y=8
Step-by-step explanation:
Y=-x+10 equation 1
y=2x+4 equation 2
-x+10=2x+4. Substitute y of first equation into 2nd equation
-x-2x+10=4
-3x=4-10
-3x=-6
x=2
solve for y by inserting x value into either equation
y=-x+10
y=-2+10
y=8
check answer
y=2x+4
8=2(2)+4
8=4+4
8=8
Answer:
109
Step-by-step explanation:
To solve you must work backward, she has 8 jars of 13 pieces so first do
8*13=104, she currently has 104 pieces. Then add back the five she ate and you get 109
Answer:
The cost of one large drink is $1.50.
(13.5-10) + 4 = (7.5 ÷ 5) = $1.50
Step-by-step explanation:
The first step is to minus the $10.00 from the $13.50, which gives us $3.50.
<em>13.5 - 10 </em>
We've done this because the pizza is irrelevant to what we're trying to figure out, so we subtract the price of the food, which as we already know is $10, to isolate the price of the 5 drinks to make it easier to find the price of just one.
Once we've done that, we're going to add on the $4.00 they got discounted to the $3.50 in order to find the original price of the drinks without using the gift certificate.
<em>(13.5 - 10) + 4</em>
This gives us $7.50, or the price of 5 large drinks. But we're only looking for the price of one. So we're going to divide the 7.50 by the total number of drinks ordered.
<em>(13.5-10) + 4 = (7.5 ÷ 5)</em>
This gives us 1.5, or $1.50.
<em>(13.5-10) + 4 = (7.5 ÷ 5) = $1.50</em>

sqrt(-49) / [ (7-2i) - (4+9i) ]
= 7i / (3 - 11i)
= 7i (3+11i) / [ (3 - 11i) (3 + 11i) ]
= (21 i - 77) / (9 + 121) = choice (d), (-77 + 21i) / 130
