Step-by-step explanation:
Hey there!
To find the average of numbers, add the numbers up and divide by the amount of numbers. 46+52+54+51+49+61+51=364. Then divide by 7 because there’s 7 days. 364/7=52. The average, or mean, temperature for the week was 52 degrees.
I hope this helps!
Answer: The fourth one
Step-by-step explanation:
Explanation:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have <span>y=5x−8</span> and we can substitute this value of y in the other equation
<span>4x+3y=33</span>
<span>4x+3<span>(5x−8)</span>=33</span> we can solve now for x
<span>4x+15x−24=33</span>
<span>19x=33+24</span>
<span>19x=57</span>
<span>x=<span>5719</span>=3</span>.
y can be obtained from the first equation
<span>y=5x−8</span>
<span>y=5⋅3−8=15−8=7</span>
Then <span>x=3</span> and <span>y=7</span>.
