Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
The correct sentence is letter "B"
Answer:
<h2>
Your Answer is C!!!!!!!!!</h2>
Steps:
Add 2y to both sides:
Simplify:
Multiply both sides by 2:
2··6+2·2y
Simplify:
x>-12+4y
Answer:
2x + 8
Step-by-step explanation:
This is the pattern:
y is 2 times x plus 8
Write this relationship as an equation.
y=2x+8
Answer:
1
Step-by-step explanation:
first, solve in the parentheses then solve from there:
1 + 4 = 5
50 - 5^2 / 25
