Answer:
48 degrees
Step-by-step explanation:
<u>1) Solve for x</u>
Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:
![A+B=90\\(2x+20)+(3x)=90](https://tex.z-dn.net/?f=A%2BB%3D90%5C%5C%282x%2B20%29%2B%283x%29%3D90)
Open up the parentheses
![2x+20+3x=90\\5x+20=90](https://tex.z-dn.net/?f=2x%2B20%2B3x%3D90%5C%5C5x%2B20%3D90)
Subtract 20 from both sides
![5x+20-20=90-20\\5x=70](https://tex.z-dn.net/?f=5x%2B20-20%3D90-20%5C%5C5x%3D70)
Divide both sides by 5
![\frac{5x}{5} =\frac{70}{5} \\x=14](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B5%7D%20%3D%5Cfrac%7B70%7D%7B5%7D%20%5C%5Cx%3D14)
Therefore, x is equal to 14.
<u>2) Determine angle A</u>
![A=2x+20](https://tex.z-dn.net/?f=A%3D2x%2B20)
Substitute x with 14
![A=2(14)+20\\A=28+20\\A=48](https://tex.z-dn.net/?f=A%3D2%2814%29%2B20%5C%5CA%3D28%2B20%5C%5CA%3D48)
Therefore, the measure of angle A in degrees is 48 degrees.

Answer:
4x
Step-by-step explanation:
4x is going to be the answer because he bakes 4 cobblers and they need c cups of flour so c is going to be the variable x. :)
Mean=all added together divide by total amount
median order them all and the middle number
mode the most common number
hope this helps you find out the answer
Step-by-step explanation:
1)
2 1/10 + 3/100 = 200/100 + 10/100 + 3/100 = 213/100 =
= 2 13/100
2)
2 1/10 + 5 3/100 = 200/100 + 10/100 + 500/100 + 3/100 =
= 713/100 = 7 13/100
3)
2.1 + 00.3 = 2.4
or did you mean + 100.3 ? then is is 102.4
4)
24/100 + 7/10 = 24/100 + 70/100 = 94/100 = 47/50
5)
3 24/100 + 8 7/10 =
= 300/100 + 24/100 + 800/100 + 70/100 =
= 1194/100 = 11 94/100 = 11 47/50
