Answer:
-70
Step-by-step explanation:
subtract 47 from both sides to get
x = -23 - 47
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 9 ← is in slope- intercept form
with slope m =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation of the parallel line.
To find c substitute (- 8, - 18) into the partial equation
- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12
y = x - 12 ← equation of parallel line
The next 3 terms are 15, 20, 25
A3= 5 x 3= 15
A4= 5 x 4= 20
A5= 5 x 5= 25
To determine the area of of the thin circular body given the diameter, use the equation, A = πd²/4.
Substituting the given diameter to the equation,
A = π(3²) / 4 = 9π/4
Thus, the area of the sand dollar is approximately 7.07 in².
Answer:
2d + 10.
Step-by-step explanation:
If four sandwiches cost $2.50 each, you have 4 * 2.5.
If two drinks cost $d each, you have 2 * d.
4 * 2.5 + 2 * d
= 10 + 2d
= 2d + 10.
Hope this helps!
