Answer:
x = 40
y = 62
Step-by-step explanation:
I figured out the answer by finding the x on the left triangle first by writing an equation:
(3x - 18) + (x + 7) + (x - 9) = 180
once I worked that I plugged in the number which was 40.
Then for the triangle to the right I also plugged in the numbers for x and got 118 degrees I took 180 and subtracted 118 to get my answer of 62 for y.
The value of the given expression is 
Solution:
Given expression is
.
Let us first convert mixed fraction into improper fraction.

Substitute this in the given expression.


To simplify the above expression, 21 and 60 are cancelled by 3.

The value of the given expression is 
Answer:
40 miles per hour
Step-by-step explanation:
change hours and minutes to hours
12 minutes = 12 minutes * 1 hr/ 60 minutes = 12/60 hrs
12/60 = 1/5 = .2 hours
1 hours 12 minutes = 1.2 hours
48 miles in 1.2 hours
48/1.2 = 40 miles/hour
Answer:
Question 1 : If you mean how many miles will he run in 1 hour then it is 1 Mile | Question 2 : 2 Miles
Step-by-step explanation:
Question 1 :
1/4 x 4 (because of the hour being split into fourths) = 1 Mile
Question 2 :
120 / 20 = 6, 6 x 1/3 = 6/3, simplified = 2
