Good Luck Flvs!
Answer:
Correct answer: Figure A's sides are 2/5 of figure B.
Step-by-step explanation:
In the order the figures are given the proportion will be:
A : B = 2 : 5
By multiplying the outer and inner members of the proportion we get:
5 · A = 2 · B ⇒ A = (2/5) · B
That mean figure A's sides are 2/5 of figure B.
This means that the two units of figure A are referred to as the five units of figure B.
God is with you!!!
Answer:
x = -1
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-2*(x-5)+7-(19)=0
Step by step solution
Equation at the end of step 1
((0 - 2 • (x - 5)) + 7) - 19 = 0
Pulling out like terms
3.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
Equation at the end of step
3
-2 • (x + 1) = 0
STEP
4
Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
2(x+2)-4x=8 the answer is 8 because it equals 8
