Help me i’m stressed

Aleks04 [339]

Answer:

<h3>m∠1 = 41°</h3><h3>m∠2 = 41°</h3>

Step-by-step explanation:

<h3>m∠1 = m∠2</h3>

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

x = 5°,

m∠1 = (6x + 11)°

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

On a road trip, a family drives 350 miles per day. How many days, d, must they travel to reach a distance of at least 1,400 mile

Semenov [28]

Answer:

Inequality symbol = ≥

Solution = d≥4

Step-by-step explanation:

If a family drives 350 miles per day, then;

1 day = 350 miles

To determine the number of days they will use to reach at least 1400mles

d days = 1400miles

Divide both expressions

1/d = 350/1400

Cross multiply

350 * d = 1400

350d = 1400

Since we are told that it ia at least 1400miles, this means the total miles can be greater than 1400. Hence the correct inequality sign to use will be a greater than or equal to sign(≥).

The expression above becomes 350d ≥ 1400

Divide both sides by 3350

350d ≥ 1400/350

d≥ 4

Hence the solution that represent the situation is d≥ 4
