Answer:
13/21
Step-by-step explanation:
find common denominator 21
Monday 2/7 = 6/21
Tuesday 1/3 = 7/21
multiply the top by what you did the bottom for the common denominator to get the equivalent fraction
add the two fraction together by keeping the denominator the same
6+7=13
so 13/21
Answer:
x = 1 or x = -5/2
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + 3 x - 2 = 3
Divide both sides by 2:
x^2 + (3 x)/2 - 1 = 3/2
Add 1 to both sides:
x^2 + (3 x)/2 = 5/2
Add 9/16 to both sides:
x^2 + (3 x)/2 + 9/16 = 49/16
Write the left hand side as a square:
(x + 3/4)^2 = 49/16
Take the square root of both sides:
x + 3/4 = 7/4 or x + 3/4 = -7/4
Subtract 3/4 from both sides:
x = 1 or x + 3/4 = -7/4
Subtract 3/4 from both sides:
Answer: x = 1 or x = -5/2
Answer:
-232
Step-by-step explanation:
-5|+23|·|4-23|=-5|8|·|4-23|
-5|8|·|4-23|=-5|8|·|-4|
-5|8|·|-4|=-58·|-4|
-58·|-4|=-58·4
-58·4=-232
