Answer:
y= cost of a popcorn
x= cost of a drink
3x+2y=45
9x+3y=110.25
y= 8.25
x= 9.5
popcorn= $8.25
drink= $9.50
Step-by-step explanation:
The answer is a. 45+2x=180
1 answer
weight of karen = k
weight of john = j
by the question
j=3k
then
case II
2j +k =875
2×3k+k=875
7k = 875
k=875/7
k=125
now
j=3k
=3×125
=375
hence john was 375 pound and karen was 125.
2 answer
let Mary be m and joes be j
by question
M=3J
CASE II
M + J=24
3J +J =24
J =24/4
J=6
NOW
M=3×6
M=18
Therefore Mary was 18 yrs old and Joes was 6 yrs old.
Answer:
Your slope of the line is -3/10.
Step-by-step explanation:
Use the following equation:
<em>m</em> (slope) = (y₂ - y₁)/(x₂ - x₁)
Let:
(x₁ , y₁) = (-2 , 7)
(x₂ , y₂) = (18 , 1)
Plug in the corresponding numbers to the corresponding variables:
<em>m</em> = (1 - 7)/(18 - (-2))
Simplify. First solve the parenthesis, then divide:
<em>m</em> = (-6)/(18 + 2)
<em>m</em> = -6/20
Simplify.
<em>m</em> = (-6/20)/(2/2) = -3/10
Your slope of the line is -3/10.

Perimeter = 10x+32
Area = 4x²+58x+28
<h2>
Step-by-step explanation:</h2>
Perimeter = 2(4x+2)+2(x+14)
Area= (x+14)(4x+2)
