Answer:
ABC = 113°
Step-by-step explanation:
If ABD is 70° and DBC is 43°
ABC is 70°+43° = 113°
These are vertical angles so they will be equal
9y + 7 = 2y + 98
subtract 7 from both sides
9y = 2y + 91
subtract 2y from both sides
7y = 91
divide by 7
y = 13
Answer:
1/2, since 1 whole is 18/18 and 1/2 is equal to 9/18
Step-by-step explanation:
Answer:
<em>x > -9 OR x < -26 </em>
Step-by-step explanation:
there are <em>two</em> possible solutions.
solve absolute value: |0.2x+3.5| > 1.7
now its either 0.2x + 3.5 > 1.7 or 0.2x + 3.5 < -1.7
solution 1 : <em>x > -9</em>
0.2x + 3.5 > 1.7
subtract 3.5 from both sides, so you get
0.2x > -1.8
and then divide both sides by 0.2 or just .2 (theyre both the same thing)
and you end up with x > -9
solution 2 : <em>x < -26</em>
0.2x + 3.5 < -1.7
subtract 3.5 from both sides, get 0.2x < -5.2
divide both sides by 0.2 or .2
end up with x < -26
hope it helps and i did it right
The greatest common factor (or GCF) is, as the name says, the greatest factor a set of numbers have in common. We can find this by listing out all the possible factors (multiples) of each number:
For 28:
<u>1</u>, <u>2</u>, 4, <u>7</u>, 14, 28
For 42
<u>1</u>, <u>2</u>, 3, 6, <u>7</u>, 21, 42
<em>(note you don't need to list out all the factors, I just did it for visual purposes)</em>
As you can see, 28 and 42 have 3 factors in common, with 7 being the greatest.
Therefore, the answer would be C: the GCF is 7.
