Answer:
x=-7
Step-by-step explanation:
Regroup terms.
8x-2=7x-98x−2=7x−9
2 Subtract 7x7x from both sides.
8x-2-7x=-98x−2−7x=−9
3 Simplify 8x-2-7x8x−2−7x to x-2x−2.
x-2=-9x−2=−9
4 Add 22 to both sides.
x=-9+2x=−9+2
5 Simplify -9+2−9+2 to -7−7.
x=-7x=−7
Wow, that is definitely a pickle, but what if you took the 14 percent that dont know, multiply it by 9590 to get how many people dont know, THEN took each percent of THAT new population to estimate how many of the "dont knows" would fall into each section then? do you get what im saying?
Answer:
25%
Step-by-step explanation:
100-80=20
20/80Ⅹ100=25%
Answer:
First choice is correct ∠A ≅ ∠D, ∠B ≅ ∠E, ∠c ≅ ∠F, AB = DE, BC = EF, AC = DF
Step-by-step explanation:
Given that triangles ABC and DEF are congruent. Now we need to choose correct congruency statements from the given choices.
We know that corresponding angles of congruent triangles are equal so we can write:
∠A ≅ ∠D
∠B ≅ ∠E
∠c ≅ ∠F
We know that corresponding sides of congruent triangles are equal so we can write:
AB = DE
BC = EF
AC = DF
comparing these with given choices we see that, First choice { ∠A ≅ ∠D, ∠B ≅ ∠E, ∠c ≅ ∠F, AB = DE, BC = EF, AC = DF} is correct.
Answer:
3 sets.
1 7 10
2 7 9
3 7 8.
Step-by-step explanation:
The sum must be 18 ( 3*6) and 7 is the middle number ( the median).
So the first and last numbers must add up to 11 with the first number less than 7. As there is no mode no number can be repeated.
So one set is 3 7 8 (the first number can't be 4 as the last number would have to be 7)
Others are 2 7 9,
1 7 10.
