Answer:
The absolute value of -1 is 1
Step-by-step explanation:
Absolute value is how far a number is from 0 on a number line. Since you can't have a negative amount of spaces, the answer is 1
Answer:
=-23y
Step-by-step explanation:
(-3y3-5y-2)+(-7y2+5y+2)
=-3yX3-5y-2-7yX2+5y+2
=-3X3y-5y-7X2y+5y-2+2
=-3X3y-7X2y-2+2
=-9y-7X2y-2+2
=-9y-14y-2+2
=-23y-2+2
=-23y

Answer:
16 miles = x miles
Step-by-step explanation:
this problem involves setting two ratios equal to each other. We call such an equation a proportion.
(1/2) inch 2 3/4 inches
x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles
(1/2)
Answer:
Step-by-step explanation:
The equation is:
√b+20 - √b = 5
The first step is we will add √b to both sides:
√b+20 -√b +√b = 5 +√b
√b+20 = 5+√b
Now take square at both sides:
(√b+20)^2 = (5+√b)^2
b+20 = 25+10√b+b
Now combine the like terms:
b+20-25-b=10√b
-5 = 10√b
Divide both the terms by 10
-5/10 = 10√b/10
-1/2=√b
Take square at both sides:
(-1/2)^2 = (√b)^2
1/4 = b
So in this type of question we add radical terms to both sides and square both sides twice....
