Answer:
The nomber of people can attend a dinner that costs $131. 50 is 14.
Step-by-step explanation:
With the information provided, it can be said that the total cost of a dinner would be equal to the initial fee plus the result of multiplying the price per person for the number of people, which can be expressed as:
c=16+8.25x, where:
c is the total cost of he dinner
x is the number of people
Now, you can replace c with 131.50 that is the cost of a dinner and solve for x to find the number of people that can attend:
131.50=16+8.25x
131.50-16=8.25x
115.50=8.25x
x=115.50/8.25
x=14
According to this, the answer is that the nomber of people can attend a dinner that costs $131.50 is 14.
Step-by-step explanation:
1.
x=5
y=4
2.x=4.2
y=19.8
3. x=16
y=70.4
4. a=28
b=25/7
5.a=20
b=18
6. a=51
b=75
7. x=30
y=21
8.a=27
b=6
hope it helps:)
ignore that fig '-'
Answer:
B. Add 2/5 to both sides
Step-by-step explanation:
Yuu have to add because it says subtract. inverse operations
Hey there!
7 * 8/10
= 7/1 * 8/10
= 7/1 * 8 ÷ 2 / 10 ÷ 2
= 7/1 * 4/5
= 7(4) / 1(5)
= 28/5
≈ 5.6
= 5 3/5
So, therefore the answer should be:
Anywhere BETWEEN 5 & 6
Good luck on your assignment & enjoy your day!

The slope-intercept form:
y = mx + b
m - slope
b - y-intercept
-------------------------------------
2x + y = -3 <em>subtract 2x from both sides</em>
y = -2x - 3
-2y = 6 + 4x
-2y = 4x + 6 <em>divide both sides by (-2)</em>
y = -2x - 3
We have the same equations. Therefore the system of equations is dependent. Has an infinite number of solutions
x ∈ R
y = -2x - 3
