Ok, so
a(b-c)=ab-ac
9 is close to 10 so
828(9)=
828(10-1)=
828(10)-828(1)=
8280-828=
7000+1280-828=
7000+452=
7452
Answer:
x = 4
Step-by-step explanation:
the given figure is of an isoceles triangle.
The two angles opposite are congruent(i.e78 degrees) .
That is the sides opposite to them are also congruent.
I. e 4x + 23 = 10x - 1
I. e 4x - 10x = -1 -23
I. e -6x = -24
I. e -x. = -24/6
Dividing by 6 to 24 we get,
-x = -4
therefore by removing the minus sign from both the sides,
the answer comes x = 4
Hello from MrBillDoesMath!
Answer:
d>4
Discussion:
I understand the question is asking us to solve for "d" in the inequality:
d + 2 > 6 => subtract 2 from both sides
d + 2 -2 > 6 - 2 => as 2 - 2 = 0
d > 6 -2 = 4
If I have misunderstood the question, please tell me.
Thank you,
MrB
Answer:
The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Answer:
1. We assume, that the number 33.39 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 33.39 is 100%, so we can write it down as 33.39=100%.
4. We know, that x is 13% of the output value, so we can write it down as x=13%.
5. Now we have two simple equations:
1) 33.39=100%
2) x=13%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
33.39/x=100%/13%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 13% of 33.39
33.39/x=100/13
(33.39/x)*x=(100/13)*x - we multiply both sides of the equation by x
33.39=7.6923076923077*x - we divide both sides of the equation by (7.6923076923077) to get x
33.39/7.6923076923077=x
4.3407=x
x=4.3407
now we have:
13% of 33.39=4.3407
