Answer:
r = 7
Step-by-step explanation:
To solve this, we can plug in a pair of x and y values and solve for r.
y = rx | Plug in a pair
42 = r*6 | Now divide both sides by 6
7 = r.
We can test this by plugging in r with a pair.
y = (7)x
77 = 7*11, 77 = 77, This equation is correct.
Answer:
x=15
Step-by-step explanation:
Hello there!
The shown angles are vertical angles
if you didn't know vertical angles are congruent
That being said we can create equation
5x + 40 = 115
now we solve for x
step 1 subtract 40 from each side
40 - 40 cancels out
115 - 45 = 75
now we have 75 = 5x
step 2 divide each side by 5
5x/5=x
75/5=15
we're left with x = 15
<span>6 yr 7 months+ 2 yr 11 months = ?
6 yr + 2 yr = 8 yr
7 months + 11 months = 18 months = 1 yr 6 months
8 yr + </span>1 yr 6 months = 9 yr 6 months
answer is C<span>. 9 yr 6 months</span>
For the first one it’s h=6 and the second one is h=-3
Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅
