Answer:
s = 5
Step-by-step explanation:
-40 = 10 - 10s
-10 -10
-50 = -10s
/-10 /-10
s = 5

Step-by-step explanation:
Ejiro + her sister's age = 64
Ejiro is 8 years older so (64 - 8) ÷ 2 = 28 her sister is 28 years old and ejiro is 28 + 8 = 36 years old
Answer:
Find the value of one the subtract it from 180
Step-by-step explanation:
Solve for X in interesting lines by finding the value of one adjacent angle and subtracting it from 180 degrees.
Method 1: Copy <span>3x + 2y = 10 and then replace the constant, 10, with C:
</span><span>3x + 2y = C Now let -2 replace x and 3 replace y: 3(-2) + 2(3) = C
Evaluate C: -6 + 6 = C = 0
Thus, the desired equation is 3x + 2y = 0.
Method 2: Solve 3x + 2y = 10 for y: 2y = -3x - 10. Then the slope is m = -3/2.
Use the point-slope formula:
y - 3 = (-3/2)(x-[-2]), or y - 3 = (-3/2)(x+2)
Show that this is equivalent to </span>3x + 2y = 0.
this is the step I hope my answer help you .
