Answer:
x = -10
Step-by-step explanation:
Combine like terms and solve for x
3x + 8 = x - 12
3x= x - 20
2x = -20
x = -10
Answer:
120°
Step-by-step explanation:
All the angles of an equilateral triangle are equal, and hence have a measure of 60°.
∵ ∠AGF is a part of equilateral Δ AGF, m∠AGF = 60°.
∵ ∠FGE is a part of equilateral Δ AGF, m∠FGE = 60°.
Also note that ∠AGE = ∠AGF + ∠FGE.
⇒ m∠AGE = m∠AGF + m∠FGE
⇒ m∠AGE = 60° + 60°
= 120°.
<h3>Interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum</h3>
<em><u>Solution:</u></em>
Given that,
Antonio wants to invest $7600 in a saving account
Antonio’s investment to double in value in 12 years
To find: Rate of interest
<em><u>The total amount using simple interest is given as:</u></em>

Where,
p is the principal
r is the rate of interest
t is the number of years
From given,
p = 7600
t = 12 years
r = ?
Antonio’s investment to double
Therefore,
A = 2(7600) = 15200
<em><u>Substituting the values we get,</u></em>


Thus interest rate required for Antonio’s investment to double in value in 12 years is 8.3 % per annum
