4. 120° ~ vertical angles are congruent
5. 13° ~ vertical angles are congruent
6. 70° ~ supplementary angles
7. 115° ~ supplementary angles
You can use the substitution method. Using the first equation in terms of y,
y = 5 - x
Substitute this to the second equation to get the value of x.
x - 2(5 - x) = 2
x - 10 + 2x = 2
3x = 2 + 10
3x = 12
x = 4
For y, just substitute the value of x that we have used in the first equation.
y = 5 - 4 = 1
Therefore, in coordinate form, that is (4,1)
Answer:
592 cm
Step-by-step explanation:
16*10/2=80
16*10/2=80
16*12=192
10*12=120
10*12=120
Add all the sum, which would equal 592.
Hope this helps.
Answer:
A
Step-by-step explanation:
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.
