Since <A is congruent to <C , so triangle ABC is an isoceles triangle and side AB is congruent to BC.
AB = BC
Therefore, we can set up an equation as following:
10x - 7 = 2x + 33
10x - 7 - 2x = 2x + 33 -2x Subtracting 2x from each sides.
8x -7 = 33
8x - 7 + 7 = 33 + 7 Add 7 to each sides.
8x = 40
Divide each sides by 40.
So, x = 5
20 minutes × 2 = 40 minutes
41 questions × 2 = 82 questions
40 minutes × 2 = 80 minutes
82 questions × 2 = 164 questions
Answer:
-1/8 > x
Step-by-step explanation:
Rewrite the equation to -1 > 8x, so -1/8 > x
Dot -1/8 on the number line, and everything on the left of that point( if right is positive ) is x .
Answer:
14981yd^2
Step by step:
1) surface area formula: SA=2bs+b^2
s=height
b=square of base
so
SA=2*71*70+71^2
SA=2*71*70+5041
SA=9940+5041
SA=14981
