Answer:
2
Step-by-step explanation:
ok so let's start
were starting off with -3/4 and were adding 2 3/4 to that and it's equal to 2 3/4 subtract 3/4
-3/4 + 2 3/4 = 2 3/4 - 3/4
2 3/4 - 3/4 = 2
-3/4 + 2 3/4 = 2
it's 2 my dude or girl i don't know
Answer:
7/10 or 70% or 0.7
Step-by-step explanation:
4 black, 10 red
10+4=14
now you put it over the total marbles
14/20=7/10
i don't know how your teacher wants you to give the answer but it is 7/10 or 0.7 or 70%
Answer:
-50
i have made it in the above picture
hope it helps
Answer:
y + 3 = - 4(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = - 4 and (a, b) = (1, - 3), hence
y - (- 3) = - 4(x - 1), thus
y + 3 = - 4(x - 1) ← in point- slope form
Step One
Find <ACB
Since AB = BC the triangle ABC is isosceles. That means that the angles opposite the equal sides are equal.
Therefore <ACB = <CAB = <40o
Step Two
find angle ABC
ABC + BAC + BCA = 180o All Triangles have 180o
<ABC + 40o + 40o = 180o
<ABC + 80o = 180o
<ABC = 180o - 80o
<ABC = 100o
Step three
Find <ADC
In a cyclic Quadrilateral The angles opposite each other are Supplementary. So because <ABC and <ADC are oppose each other they will equal 180o.
<ABC + <ADC = 180o
100o + <ADC = 180o
<ADC = 180o - 100o
<ADC = 80o
Step Four
Find <ADE
<ADC +< ADE = 180o
<ADE + 80o = 180o
<ADE = 100o
