Answer:
A, C & D
Step-by-step explanation:
A) 1 + 3x = -x + 4 {subtract 1}
1 + 3x -1 = -x + 4 - 1
3x = -x + 3 {add x}
3x + x = -x + 3 + x
4x = 3 {Divide by 4}
4x/x = 3/4
x = 3/4
C) 1 + 3x = -x +4 {Add x}
1+ 3x + x = - x +4 + x
1 + 4x = 4 {subtract 1}
4x = 4 - 1
4x = 3 {Divide by 4}
D) 1 + 3x = -x + 4 { Subtract 3x}
1 = -x + 4 -3x
1 = -4x + 4 Subtract 4}
1 - 4 = -4x
-3 = -4x {Divide by -4}
-3/-4 = x
x = 3/4
x = 3/4
Try this:
1) if ratio=100/3, then 100/3=2600/x
x=26*3=78 p.
2) if (-2) ⇒ -3*(4)=-12 ⇒ answer: (-2;-12)
if (-1) ⇒ -3*(1)=-3 ⇒ answer: (-1;-3)
if 0 ⇒ -3*0=0 ⇒ answer: (0;0)
if 1 ⇒ -3*1=-3 ⇒ answer (1;-3)
if 2 ⇒ -3*4=-12 ⇒ answer: (2;-12)
The cube root is 10 bc 10x10x10 = 100
Answer:
Step-by-step explanation:
Givens
Let the width = x
Let the length = x + 5
Equation
2w + 2W = P
Solution
2x + 2(x + 5) = 192 Remove the brackets <=== Answer
2x + 2x + 10 = 192 Combine like terms
4x + 10 = 192 Subtract 10 from both sides
4x = 192 - 10
4x = 182 Divide by 4
4x/4 = 182/4
x = 45.5
