Answer:

She sneezed for 138.286 weeks in a row. You need days of week to create a proper conversion.

Step-by-step explanation:

There are 7 days in a week. There are 978 days shown.

You can depict it as this:

978 = 7x; x is the amount of weeks.

Divide both sides by 7

138.285714 = x

Round to three decimals

x = 138.286

In ∆ABC, m∠B=α. Find the measure of the angle, in degrees, between the altitudes dropped from the vertices A and C
Sergio [31]

The expression to find the value of the final angle of the triangle will be 180° - 40° - α.

<h3>How to solve the triangle?</h3>

Your information is incomplete as the triangle isn't attached. Therefore, an overview will be given.

Firstly, it's important to know that the total angle in a triangle is 180°. A triangle has three sides. In this case, angle B is given as α.

Let's assume that another angle is given as 40°. Therefore, the expression to find the value of the final angle will be 180° - 40° - α

Y=-5x + 22<br> -2x - 8y = 14
laiz [17]

Step-by-step explanation:

Put the value y.

-2x-8(-5x+22)=14

-2x+40x-176= 14

38x-176 =14

38x = 190

x=5

Now put the value of X to find Y

Y= -5(5)+22= -25+22 = -3

=>X=. 5

=>Y= -3

How many solutions does the following equation have? 10x-1=10x+4
zimovet [89]
  • Your answer is no solution.
  • Because if we transpose 10x to the left hand side with a change in the symbol, then it will become 0.
  • 10x - 1 = 10x +4
  • or, 10x - 10x = 4 + 5
  • or, 0 = 9
  • Hence, the equation has <em><u>no solution</u></em>.

Hope you could get an idea from here.
