Answer:
20
Step-by-step explanation:
To solve, I converted the fraction to decimals
1.5/(2.25-0.75) X 1.8 = 1.5/1.5 X 1.8 = 1.8
3.2 - 1.20 = 2
3(2/30 - 1/30) = 3(1/30) = 3/30 = 1/10 = 0.1
2(2/64 / 1/16) = 2(32/64) = 2 (1/2) = 1
1.8/0.1 + 2/1 = 18 + 2 = 20
Answer:
The slope is -2
Step-by-step explanation:
(0,4) (3,-2)
remeber the equation is Y2-Y1/X2-X1
Y2 = -2
Y1 = 4
X2=3
X1=0
Plug it in the euqation to see if it works

Step-by-step explanation: What do you mean by simplify?
We can l<span>abel the length (l), width (w), and height (h) of the prism and use the </span>formula<span>, SA=2lw+2lh+2hw, because it has '6' faces and to find the </span>surface area put the values in the formula:
SA=2(6)(3)+2(6)(2)+2(2)(3)
SA=36+24+12
SA=72
Answer: 6 people ordered for the lobster dinner.
2 people ordered for the steak dinner.
Step-by-step explanation:
Let x represent the number of people that ordered the lobster dinner.
Let y represent the number of people that ordered the steak dinner.
A family of 8 went out to dinner. This means that
x + y = 8
Each person either ordered the lobster dinner, which costs $25, or the steak dinner which cost $20. The total cost of all the meals is $190. This means that
25x + 20y = 190 - - - - - - - - - -- -1
Substituting x = 8 - y into equation 1, it becomes
25(8 - y) + 20y = 190
200 - 25y + 20y = 190
- 25y + 20y = 190 - 200
- 5y = - 10
y = - 10/ - 5
y = 2
x = 8 - y = 8 - 2
x = 6
