Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A
Answer:
The remainder would be what remains from the equation so in this case it would be about 1.3 or so.
Step-by-step explanation:
If you divide 9 by 7 then you get for an answer 1.285 and so on. So your answer will be 1.3 or 1.2 because you round up the number from either the first number in the decimal or the second number in the decimal.
Answer:
5
Step-by-step explanation:
you add up all the numbers, then divide but how many numbers there are:
all add up to 40, divide the 40 by 8 to get 5
Answer:
x = -
and y = 
Step-by-step explanation:
2x + 5y = 11
7x + 4y = 2
Let's try elimination here since we have a system of equations:
-7(2x + 5y = 11) = -14x - 35y = -77
and
2(7x + 4y = 2) = 14x + 8y = 4
The <em>x</em>'s cancel out now so let's combine the two equations:
-35 + 8 = -27
-77 + 4 = -73
-27y = -73
y =
Now that we have <em>y</em>'s value, let's plug that value in for <em>y</em> in the other equation. You may choose whichever equation you want to solve for <em>x</em> but it is recommended to use the easiest one. (Since this value is complicated, it won't really matter.)
2x + 5() = 11
2x + 
= 11
2x = -
x = -
To check and make sure you have the correct values, plug both values into the orginal equation and make sure the equation is true.
Answer: 3.3
Step-by-step explanation:
200(x-0.3)=600
Multiply x by 200 and 0.3 by 200
200x-60=600
Add 60 to both sides
200x-60=600
+60 +60
Add them
200x=660
Divide
660/200 = 3.3
Answer: 3.3
