Speed test cost $5 each and large one-topping pizzas cost $6 each write an equation that represents the total cost t of c large
yKpoI14uk [10]

<u>Answer:</u>

Equation t = 5c + 6d represents total cost t of c large pizzas and d large one-topping pizzas

<u>Solution:</u>

Given that

Cost of large pizza = $5 each

Cost of large one-topping pizza = $6 each

Need to write the equation that represents total cost t of c large pizzas and d large one topping pizzas.

From given information

Cost of 1 large pizza = 5

So cost of c large pizzas   = c x 5 = 5c

Cost of 1 large one-topping pizza = 6

So cost of d large one-topping pizzas   =d x 6 = 6d

<em>Total cost t = cost of c large pizzas + cost of d large one-topping pizzas    </em>

=> t = 5c + 6d

Hence equation t = 5c + 6d  represents total cost t of c large pizzas and d large one-topping pizzas.

12 out of 30 people chose blue as their favourite colour, calculate the angle you would use for blue on a pie chart
Vladimir79 [104]
One way:
\frac{12}{30} x 360  (360 degrees in a circle which is what a pie chart is)
or \frac{2}{5} x 360
which is \frac{2}{5}x \frac{360}{1} = 144⁰ angle

Which ordered pair is a solution of the equation? y=-2x+5y=−2x+5 (Choice A) A Only (2,-9)(2,−9) (Choice B) B Only (-2,9)(−2,9) (
Firdavs [7]

Answer:

Choice B: Only (-2, 9)

Step-by-step explanation:

Of the two choices, only the point (-2, 9) satisfies the equation:

... y = -2x +5

... 9 = -2(-2) +5 = 4 +5 = 9

Lines AD and BC are parallel.
allochka39001 [22]

*see attachment for the missing figure

Answer:

Angle ADE = 45°

Angle DAE = 30°

Angle DEA = 105°

Step-by-step explanation:

Since lines AD and BC are parallel, therefore:

Given that angle Angle CBE = 45°,

Angle ADE = Angle CBE (alternate interior angles are congruent)

Angle ADE = 45° (Substitution)

Angle DAE = Angle ACB (Alternate Interior Angles are congruent)

Angle ACB = 180 - 150 (angles on a straight line theorem)

Angle ACB = 30°

Since angle DAE = angle ACB, therefore:

Angle DAE = 30°

Angle DEA = 180 - (angle ADE + angle DAE) (Sum of angles in a triangle)

Angle DEA = 180 - (45 + 30) (Substitution)

Angle DEA = 180 - 75

Angle DEA = 105°
