Help me i’m stressed

Aleks04 [339]

Answer:

Step-by-step explanation:

${(6x + 11)}^{o} = {(10x - 9)}^{o} \\ 11 + 9 = 10x - 6x \\ 20 = 4x \\ \frac{20}{4} = \frac{4x}{4} \\ 5 = x \\$

x = 5°,

m∠1 = (6x + 11)°

${(6x + 11)}^{o} \\ 6(5) + 11 \\ 30 + 11 \\ {41}^{o} \\$

pishuonlain [190]

Comment
You need to set up a direct proportion. You have to relate Keith and Jared's ages to the ratio you were given.

Givens
Keith is 24
Keith / Jared = 3/5
J = Jared

Solution
3/5 = 24 / J Cross multiply
3*J = 5 * 24 Combine factors on the right.
3J = 120 Divide by 3
J = 120 / 3
J = 40

Conclusion
Jared is 40 years old.
