Find the value of X, angle A and angle C

X=12

A=36

C= 86

Step-by-step explanation:

to find x:

7x+2+3x=122

solve for x

x=12

to find a:

the 3x is a corresponding angle to A, so A is 3 times 12 which is 36

to find C:

7x+2, same thing as before, substitute the x

7(12)+2

86

To check, add up all, should be 180

58+36+86=180

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
