X - invested for the money at 11%
70 000 - x - deposited at 12%
0.11x + 0.12(70000-x)=7900
0.11x + 8400 - 0.12x = 7900
8400- 7900 = 0.01x
500 = 0.01x
x=50 000 invested at 11%

Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
(24)(x)=(83)(x)−10
Step 1: Simplify both sides of the equation.
(24)(x)=(83)(x)−10
16x=512x+−10
16x=512x−10
Step 2: Subtract 512x from both sides.
16x−512x=512x−10−512x
−496x=−10
Step 3: Divide both sides by -496.
−496x
−496

Answer:
Step-by-step explanation:
Calculating the volume of a cylinder is very similar to determining the area of a prism. You can ... Recall that the area of a circle is equal to pi times the radius squared. ... V = Π(3.6)2(4) Here we started by replaced r with the radius and h with the height. ... V = 5400Π mm3 ← If you are
X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
