<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- x = y
- 2(70 + 60) + x + y = 360
<u>Work:</u>
- 2(130) + x + x = 360
- => 260 + 2x = 360
- => 2x = 360 - 260
- => 2x = 100
- => x = 50
Hence, <u>the value of x is 50°.</u>

Good evening ,
_______________
2(7) + 5(1) + 3(-3) = 10
3(7) - (1) + 4(-3) = 8
5(7) - 2(1) + 7(-3) = 12
Then (7,1,-3) is a solution to system

Answer:
Step-by-step explanation:
<u>Use ratios and solve:</u>
- 1 in ÷ 7 ft = x in ÷ 28 ft
- x = 28/7 in
- x = 4 in
Answer:
For children ages 2 to 5, limit screen time to one hour a day of high-quality programming. As your child grows, a one-size-fits-all approach doesn't work as well. You'll need to decide how much media to let your child use each day and what's appropriate.
Step-by-step explanation:
For kids aged 2 to 5, screen time should be limited to 1 hour per day, and parents should watch the programs with their child. Also, parents should have times when screens are turned off, and bedrooms should be media-free.
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.
