Answer:
Step-by-step explanation:
y = 2x - 1
y = x - 8 ------ (i)
substitute y = 2x - 1 in equation (i)
2x - 1 = x - 8
2x = x - 8 + 1
2x = x - 7
2x - x = -7
x = -7
Substitute x value in equation (i)
y = -7 - 8
y = -15
Answer:

Answer:
$5
Step-by-step explanation:
We want to find the cost of a notepad considering a magazine costs $3 and we buy 2 notepads and the total cost of the magazine and the 2 notepads is $13 so we can set up an equation to represent this situation. Let 'n' be notepads and that's the value we are solving for so,
⇒ Form the equation
→ 2n + 3 = 13
⇒ Minus 3 from both sides to isolate 2n
→ 2n = 10
⇒ Divide both sides by 2 to find the cost of one notepad
→ n = 5
The cost of one notepad is $5 considering that a magazine cost's $3 and two notepads and total is $13.
Answer:
7.92 miles (aprox.)
Step-by-step explanation:
1 hour = 60 minutes
19mph = 19miles/hour = 19miles/60 minutes
Proportions:
19 miles ⇔ 60 minutes
W miles ⇔ 25 minutes
W = 19*25/60
W = 7.92 miles (aprox)
Hey there!
In a rhombus, opposite angles are congruent. This means that 2y is equal to y+34. Let's set up an equation to solve for y.
2y=y+34
We subtract y from both sides.
y=34
Therefore, y=34°
I hope that this helps! Have a wonderful day!
