Answer:
B = 25
Step-by-step explanation:
x/100×8.5=2.1
8.5x/100=2.1
8.5x=100×2.1
8.5x=210
8.5x/8.5=210/8.5
x=24.70
x=25
Answerc and d
Step-by-step explanation:
2+3+5
6 (dinner) + 8 (movie) + 4 (popcorn) = $18 total
Associative Property of Addition is used because there are 3 numbers, and regardless of where they are put or how they are placed (in order of not), they all still add up to 18 no matter how you move or place them.
Answer:
C) △JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
Step-by-step explanation:
If L' were (-3,-4), it would be a reflection of L across the x-axis as J' and K' are with respect to J and K. Unfortunately, because it is not, the side lengths J'L' and K'L' of triangle J'K'L' are different from those of triangle JKL. This ensures the triangles JKL and J'K'L' are <em>not congruent</em>.
Answer:
<em>x(y+z)=(x×y)+(x×z) shows the distributive property of multiplication over addition.</em>
