Answer:
Step-by-step explanation:
The triangle’s angles add up to 180°
So (x + 10) + (2x + 20) + (2x - 5) = 180
x + 10 + 2x + 20 + 2x - 5 = 180
5x + 25 = 180
5x = 155
x = 31

What is the expression after applying the distributive property? −5/8(−3+(−7))
Answer:
[tex]-\frac{5}{8} (-3 + -7) = -\frac{5}{8}(-3) + -\frac{5}{8}(-7)[/tex]
The expression after applying distributive property is [(-[tex]\frac{5}{8}[/tex]) × (-3)] + [(-[tex]\frac{5}{8}[/tex] ) × (-7)] = 50/8
What is Distributive Property?Distributive property shows us how to multiply an arithmetic number or an algebraic expression with two or more numbers or expressions within brackets.
This can be symbolically represented as :
X ( Y + Z ) = XY + XZ
The expression given here is -[tex]\frac{5}{8}[/tex] (-3 + (-7)).
Applying distributive property, we get,
-[tex]\frac{5}{8}[/tex] (-3 + (-7)) = [(-[tex]\frac{5}{8}[/tex]) × (-3)] + [(-[tex]\frac{5}{8}[/tex] ) × (-7)]
= (15/8) + (35/8)
= 50/8
The expression -[tex]\frac{5}{8}[/tex] (-3 + (-7)) after applying distributive property changes to the expression [(-[tex]\frac{5}{8}[/tex]) × (-3)] + [(-[tex]\frac{5}{8}[/tex] ) × (-7)] = 50/8.

A vendor sells tacos and burritos. One family buys 3 tacos and 2 burritos for $9.25. Another family buys 7 tacos and 4 burritos for $19.75. Find the cost of each item.
Answer:
Taco: $1.25
Burrito: $2.75
Step-by-step explanation:
Let x = tacos
y = burritos
Since the first family bought 2 burritos, we multiply y by 2; we multiply x by 3 since they bought 3 tacos.
3x + 2y = 9.25
We do basically the same thing for the other family
7x + 4y = 19.75
We'll use elimination method to solve this
7x + 4y = 19.75
3x + 2y = 9.25
Multiply the bottom equation by -2
7x + 4y = 19.75
(3x + 2y = 9.25)-2
7x + 4y = 19.75
-6x - 4y = -18.5
Now subtract the equations and we get this
x = 1.25
A taco costs $1.25
Plug the new x into one of the original equations
3(1.25) + 2y = 9.25
3.75 + 2y = 9.25
- 3.75 - 3.75
2y = 5.5
2y/2 = 5.5/2
y = 2.75
A burrito costs $2.75
I NEED TO ANSWER ASAP PLEASE AND THANKS
Answer:
x(n) ≤ 678(n)
Step-by-step explanation:
let n represent per night.
it cannot cost more than $678 per night (n). If x was how much you paid, it would depend on the number of nights. So that is represented by x(n). Then, add the rest of the inequality (≤678(n))and the answer is x(n) ≤ 678(n)

Answer:
107 people
Step-by-step explanation:
Their budget is $3,500 and they have to spend $70 for the clean up fee:
$3,500 - $70 = $3430
If it is $32 per person, then find out how many $32 fit into their remaining budget of $3430
$3430 ÷ $32 = 107.1875
You can't have part of a person, so the greatest number of people they can invite is 107

Answer:
Domain = {1,2,3,4,5,6} and Range = {42,49,56,63,70,77The given function is :
y = 7x + 35
Where
x is no of members
y is the monthly cost
Your group has enough money for up to six members to joim fitness club. It means domain (the set of input values) are:
Domain = {1,2,3,4,5,6}
Put x = 1 to 6 one by one,
y = 7(1) + 35 = 42
y = 7(2) + 35 = 49
y = 7(3) + 35 = 56
y = 7(4) + 35 = 63
y= 7(5) + 35 = 70
y = 7(6) + 35 = 77
Range = {42,49,56,63,70,77}
