Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
We apply the following property:
(x^n)^m = x^(n • m)
Let m = 2
(P^1/2)^2 = P^(1/2 • 2) = P
Answer:
-1.05 -.75p
Step-by-step explanation:
-3(0.15+0.2+0.25p)
Distribute the 3 to each term in the parentheses
-3(0.15)+-3(0.2)+-3(0.25p)
-.45 -.6 -.75p
Combine like terms
-1.05 -.75p
20 ÷ (5 × 2 - 6) + 8=20:(10-6)+8=20:4+6=5+6=11
(20 ÷ 5) × 2 – 6 + 8=4*2-6+8=8-6+8=2+8=10
20 ÷ (5 × 2) – 6 + 8=20:10-6+8=2-6+8=-4+8=4
(20 ÷ 5) × (2 – 6) + 8=4*(-4)+8=-16+8=-8
Answer:
Infinitely many solutions.
Step-by-step explanation:
12(x+3)=4(2x+9)+4x
12x+36=8x+36+4x
12x+36=12x+36
infinitely many solutions
