Answer:

x=24

Step-by-step explanation:

Since line A and B are parallel, 3x+7 is equivalent to Angle 6 as they are corresponding angles.

We also know that 4x+5+Angle 6 = 180 as they are a linear pair. We can use substitution and substitute 3x+7 for Angle 6...

4x+5+3x+7=180

7x+12=180

7x=168

x=24

Answer:

x= 24

Step-by-step explanation:

Given: A || B

This means that A is parallel to B.

Properties we can make use of when we have parallel lines are corresponding angles (e.g. ∠1= ∠4) and interior angles (e.g. ∠2 +∠4= 180°).

Let's make use of corresponding angles.

∠6= (3x +7)° (corr. ∠s, A||B)

Since D is a straight line and the sum of the angles on a straight line is 180°,

(4x +5)° +∠6= 180° (adj. ∠s on a str. line)

Substitute ∠6= (3x +7)°:

(4x +5)° +(3x +7)°= 180°

Simplify:

(7x +12)°= 180°

7x +12= 180

7x= 180 -12

7x= 168

Divide both sides by 7:

x= 168 ÷7

x= 24

The weather forecast says that the probability of being cloudy tomorrow is 30% and the probability of raining is 25%. If it is c

Bumek [7]

<h3>Answer:</h3>

$\large\boxed{C).\,13.5\%}$

<h3>Step-by-step explanation:</h3>

In this question, we're trying to find the probability of it being cloudy and raining.

In this case, we know that:

Probability of it being cloudy is 30%
Probability of it raining is 25% (this is necessarily not needed)
If it's cloud, the probability of it raining is 45%

With the information above, we can find the probability.

We know that from a 100% scale, the chance of it being cloudy is 30%.

We know that if it's cloudy, the chances of raining is 45%

To find the probability of it being cloudy and raining, we would multiply 0.3 (30%) by 0.45 (45%)

Solve:

$0.3*0.45=0.135\\\\\text{Move the decimal place two times to the right}\\\text{to turn it into a percent}\\\\\boxed{13.5\%}$

Your answer would be C). 13.5%

Solve by substitution <br> X^2= 2y + 10<br> 3x-y = 9

Viefleur [7K]

Answer:

$x=-4\\ x=-2\\ y=-21\\ y=-15$

Step-by-step explanation:

$x^{2} =2y+10$

$y=-9+3x$

$x^{2} =2(-9+3x)+10$

$x^{2} =-18+6x+10$

$x^{2} =6x-8$

$x^{2} -6x+8$

$x=-4, -2$

$y=-9+3(-4)$

$y=-9-12$

$y=-21$

$y=-9+3(-2)$

$y=-9-6$

$y=-15$
