It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23
x has to equal 1. 3/10 + 1/5 = 1/2
the equation is now 1/2 + x = 1 1/2x
x = 1
1 1/2 = 1 1/2
Answer:
y = -7/2 + 5x/2
t = 3k/v
f = 9c/5 +32
Step-by-step explanation:
Answer:
A.) JH = 1 in
B.) GH = 3/4 in
C.) m∠F = 62°
D.) m∠J = 118°
Step-by-step explanation:
In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.
A.) JH = FG = 1 in
B.) GH = FJ = 3/4 in
C.) m∠F = m∠H = 62°
D.) m∠J = m∠G = 180° -62° = 118°
