For the first one it's 8.25 and the second one is 7.625. I found this by dividing the cost to the sandwich to find the unit rate. (Does that help?)
Answer:
<h3>n = -8</h3>
Step-by-step explanation:
For two lines to be parallel, they must have the same slope
Get the slope of each line
For L1;
m1 = -2-4/1-n
m1 = -6/1-n
For L2;
m2 = 5-3/1-4
m2 = 2/-3
m2 = -2/3
Since they have the same slope, m1 = m2
-6/1-n = -2/3
6/1-n = 2/3
Cross multiply
2(1-n) = 6(3)
2-2n = 18
-2n = 18 - 2
-2n = 16
n = -16/2
n = -8
Hence the value of n is -8
Answer:
<h2>128m³</h2>
Step-by-step explanation:
Volume = L x W x H
L = 4
W = 4
H = 8
Volume = 4 x 4 x 8
Volume = 16 x 8 = 128m³
Answer:
<h2>Below, Hope this helps :)</h2>
Step-by-step explanation:
The variable t represents the amount of gas in mom's truck. Since we need to find a number that is 50% more than 12, we use 1.5 (we would use 2 if we want 100% more, so it makes sense that we use 1.5, since we want to add 1/2 of 12 to 12. The answer is 18.)
