<u>Answer </u><u>:</u>

In the given quadrilateral ABCD ,

  • Angle BCA = 18°
  • Angle ACD = 62°

Angle BCA = Angle CAD ( alternate interior angle )

Now in triangle CAD ,

We have two angles so by using angle sum property we can find the required third one ,

  • Angle CAD + Angle ACD + Angle ADC = 180°
  • 18 + 62 + Angle ADC = 180
  • 80 + Angle ADC = 180
  • Angle ADC = 180 - 80
  • Angle ADC = 100

Answer:

∠ ADC = 100°

Step-by-step explanation:

∠ CAD = ∠ BCA = 18° ( alternate angles )

The sum of the 3 angles in a triangle = 180° , then

∠ ADC = 180° - (62 + 18)° = 180° - 80° = 100°

4x - 5y = 15<br> find the slope and y-intercept
Mazyrski [523]

Answer:

slope=4/5

y-intercept = -3

Step-by-step explanation:

first we need to rewrite the expression to

y=mx+b

were b is the y-intercept and m the slope

4x-5y=15\\\\4x-5y+5y=15+5y\\\\4x+0=15+5y\\\\4x=5(3)+5(y)\\\\4x=5(3+y)\\\\\frac{1}{5}*4x= \frac{1}{5}*5(3+y) \\\\\frac{4x}{5}=3+y\\\\\frac{4x}{5} -3=3+y-3\\\\\frac{4x}{5} -3=y+0\\\\y=\frac{4x}{5} -3\\\\y=\frac{4}{5}x-3

so there we have it

m=\frac{4}{5} \\\\b=-3

During the summer , you want to earn at least $150 per week. You can earn$10 per hour working for a farmer, and $5 per hour baby
almond37 [142]
X = nr. hrs working for a farmer;
y = nr. hrs. babysitting;
x + y <= 25;
10x + 5y >= 150

a) Solve the system => one of the solution is  x =5; y = 20(babysitting)
b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.

Tom pays $1506 in rent every month. This amount is $50 more than twice what his brother Arturo pays for
Talja [164]

Answer:

$3062

Step by Step Explanation:

Arturo's rent can also be written as an expression

2t + 50

This is basically showing that two of Tom's rent plus $50 gives you his brother's rent.

So 2(1506) + 50

3012 + 50

3062
