A) satellites</h3><h3>D) Weather balloons</h3><h3>E) Automated weather stations</h3>
=====================================================
Explanation:
Satellites are used to measure things like the formation of storms and predicting where they will go. They provide a big picture of the climate as a whole, and they're useful for studying climate patterns.
Weather balloons are used to measure humidity, wind speed, temperature and pressure in the atmosphere. They are useful because they are very inexpensive compared to satellites, and can be made quicker.
Automated weather stations are locations where much of the same things are measured with weather balloons, though on the ground rather high in the air. In addition, weather stations will likely have a rain gauge to measure how much rain has fallen in a certain area.
14 chicken wings is $22.40
x chicken wings is $12.80
14x12.80 =179,20
179,20/22,40 = 8
he bought 8 chicken wings
Answer:
It's just a simultaneous equation
Step-by-step explanation:
Let a big bag of sugar = x
Let a small bag of flour = y
x+x+y = 12kg
2x+y = 12kg ... 1
x-y = 2kg ... 2
Add 1 and 2
2x+y = 12
+
<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>
3x = 14
x = 14/3 = <u>4.66</u>
Substitute value of x into 1
2(4.66)+y = 12
9.333 + y = 12
12 - 9.333= 12
y = <u>2</u><u>.</u><u>6</u><u>6</u>

1 ton equals 2000 pounds
so 3 tons equals 6000 pounds
Answer: 3 tons
1. x+5y=8
2x- 5y=1 What you do is find the number/variable that are the same( here is is the +5y and -5y. You want them to be opposites(-,+) so that they cancel each other out. if they are not opposites, then multiply one equation by a negative sign to change it. Cross out the 5y's. Now you can combine like terms-x+2x=3x, and 8+1=9, so now your equation will look like this:
3x=9
x=9/3
x=3
now take x=3 and plug it into the first equation to solve for y. x+5y=8, so 3+5y=8
5y=8-3
5y=5
y=5/5
y=1
(3,1) are your answers.
now do the same with the other problems.
