Answer: desktop = $1750, laptop = $1900
<u>Step-by-step explanation:</u>
Let x represent the cost of the desktop
then x + 150 is the cost of the laptop.
.07x + .055(x + 150) = 227
.07x + .055x + 8.25 = 227
.125x = 218.75
x = 1750
desktop (x) = $1750
laptop (x + 150) = $1750 + $150 = $1900
Answer:
55.9548
Step-by-step explanation:
35.64 ÷ 2 = 17.82
17.82 × 3.14 = 55.9548
Volume = length x width x height
So,
Volume = 2 1/3in x 2in x 1 2/3in
Volume = 7/3in x 6/3in x 5/3in
Volume = 210/9in^3
Volume = 70/3in^3 or 23 1/3in^3
Answer:
X=16
Step-by-step explanation:
X-18=-2
+18 +18
X=-2+18
X=16
<span> x - 4y = -5
-x + 6y = 7
---------------add
2y = 2
y = 1
</span> x - 4y = -5
x - 4(1) = -5
x - 4 = -5
x = -1
answer
x = -1 and y = 1
