Answer:

3 sips = 1 gulp

Step-by-step explanation:

We will solve this problem using the given simultaneous equations. We will use either substitution or elimination. For this problem, we will use elimination.

Let s = No. of sips

Let g = No. of gulps

5s + 4g = 1 -> (1)

13s + 7g = 2 -> (2)

We will multiply the first equation by 7 and multiply the second equation by 4 so that both equations have '28g'.

5s + 4g = 1 -> (1) × 7

13s + 7g = 2 -> (2) × 4

------------------------------

35s + 28g = 7

52s + 28g = 8

We will subtract the second equation from the first equation.

- 17s = - 1

s = - 1 / - 17

s = 1 / 17

We will substitute the obtained value for 's' into the first equation to solve for 'g'.

5 ( 1 / 17 ) + 4g = 1 -> (1)

5 / 17 + 4g = 1

4g = 1 - 5 / 17

g = ( 12 / 17 ) / 4

g = 3 / 17

Therefore, as 3 / 17 ÷ 1 / 17 = 3:

3 sips = 1 gulp

Write an equation of the parabola in intercept form with x-intercepts of 12 and -6; and an axis of symmetry of (14, 4).
xenn [34]

Intercept form is: y = a(x - p)(x - q)  

It is given that:  p = 14, q = -6, x = 14, y = 4

4 = a(14 - 12)(14 - (-6))

4 = a(2)(20)

4 = 40a

\frac{4}{40} = \frac{40a}{40}

\frac{1}{10} = a

Answer: y = \frac{1}{10}(x - 14)(x + 6)

Could ΔABC be congruent to ΔADC by SSS? Explain.
Vera_Pavlovna [14]
There are 5 ways to test if two figures are congruent, namely;
side-angle-side(SAS)
Angle-side-angle (ASA)
Angle-angle-side(AAS)
Hypotenuse-leg (HL)
3 Sides (SSS)
here we shall focus on SSS. When the three corresponding sides of 2 figures say a triangle have the same length we will conclude that the triangles are congruent by SSS.
Therefore from our choices we can conclude that   triangles ABC and ADC are only congruent if the two other side have the same length and BC=DC.

The answer is yes;
B] Yes, but only if BC=DC

A share of stock in the bree medical supply company is quoted at 35 1/4,suppose you hold 20 shares of that stock which you bough
kodGreya [7K]
Hi there, we know the total number of stocks bough is 20, the rate was 31 1/2=63/2, 20*63/2=10*63=630 dollars, the rate they were sold is 35 1/4=141/4 dollars, 5*141=705 dollars, the amount of profit is 20 stocks. So, 705-630=75 dollars. So, the answer is C. You made a profit of $75.00

I will give BRAINLIEST! HELP PLEASE.!!!<br><br> 2. Find each measure. <br> m&lt;1 m&lt;2 m&lt;3
fredd [130]
<h3>Answer: Choice B</h3>

Angle 1 = 147 degrees

Angle 2 = 80 degrees

Angle 3 = 148 degrees

======================================================

Work Shown:

(angle 1) + 33 = 180

angle 1 = 180-33

angle 1 = 147 degrees

---------------

Focus on the left most triangle that has angles 33 and 47 as interior angles. The missing angle is 180-33-47 = 100 degrees

The angle exterior to this 100 degree angle is angle 2

angle 2 = 180-100 = 80

We have enough info to conclude the answer must be choice B.

---------------

Let's keep going to find angle 3

The vertical angle for the 100 degree angle is also 100 degrees. This second 100 degree angle is part of the triangle on the right

This triangle on the right has interior angles 100 and 48

The missing interior angle is 180-100-48 = 32

The angle supplementary to this is 180-32 = 148, which is angle 3.
