Answer:
The cost of each drink is $6.58
Step-by-step explanation:
<u><em>The correct question is</em></u>
Someone buys 4 drinks and 2 popcorn and spent a total of $32.50. Each drink is $3.50 more than a popcorn. How much does each drink cost?
Let
x ----> the cost of each drink
y ----> the cost of each popcorn
so
----> equation A
isolate the variable y
----> equation B
Solve the system by substitution
substitute equation B in equation A
solve for x
therefore
The cost of each drink is $6.58
Answer:
When you add 2+3 which equals 5 so it’ll be y=5x-7. And plug in y into the other equation. 5x-7-5x+8=0. -7-8=0, -7-8 =-1 therefore there is no solution because-7-8= -1 not 0.
Step-by-step explanation:
Answer:
70°
Step-by-step explanation:
Sum of angles in a parallelogram is 360°
Opposite angles are equal
2(16x - 2) + 2(8x + 14) = 360°
32x - 4 + 16x + 28 = 360°
32x + 16x + 28 - 4 = 360°
48x + 24 = 360°
48x = 360 - 24
48x = 336
x = 7
m< E = 8x + 14
Substitute for x
= 8(7) + 14
= 56 + 14
= 70°
