Answer:
x= 6
Step-by-step explanation:
Answer:
a = 16.733
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
a^2 + 9^2 = 19^2
a^2 = 19^2 - 9^2
a^2 = 361-81
a^2 =280
Taking the square root of each side
sqrt(a^2) = sqrt(280)
a = 16.73320053
Rounding to the nearest thousandth
a = 16.733
Answer:
I won't solve i'll translate like you asked
Step-by-step explanation:
13) x - 5 = 21
14) 12 × y = 48
15) b + 10 = 13
If you want I can solve.
HOPE THIS HELPED
Subtract 13 from both sides.
-13
-7 = -20
-2x = -20
Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.
-2/-2 = 1
-20/-2 = 10
Your answer:
x = 10
Expression: 2.8 * 10⁷ / 1.4 * 10³
= 2 * 10⁷⁻³
= 2 * 10⁴
In short, Your Answer would be: Option A
Hope this helps!
