Answer: 5
Step-by-step explanation: Let us pretend that the number is x. So, the equation will be like this:
3x-5=2x
x=5
<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
12)
well, the picture has a length of (x + 2.5) and a width of (x).
if we extend the picture 1 inch on all sides, it'll end up like the picture below.
13)
let's find the area of the larger rectangle, that includes the smaller rectangle, and then let's find the area of the smaller rectangle, and after <u>subtracting the smaller area from the larger area</u>, what's leftover is the shaded region.
14)
we'll do the same thing here as we did in 13)
Answer:
35/8
Step-by-step explanation:
First, we solve the whole number parts; 3 + 1 = 4.
Then the fractions finding the LCD of 1/8 and 1/4 which is 8.
1/8 + 2/3 = 3/8
Then we get 4 3/8.
Now we simplify it;
Multiply the denominator by the whole number. 8 * 4 = 32.
Add the answer, 32, to the numerator (3), which gives us 35.
We get 35/8.
Symmetric property, I remembered the answer for this for my summer school. This is one of the equivalence properties of equality.
