Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
Answer:
The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
Step-by-step explanation:
Let the area of Country B be x
We are given that Country A is larger by 473 square kilometers.
Area of Country A = x+473
Total area of both countries = x+x+473
Total area of both countries = 2x+473
We are given that The combined land area of the countries A and B is 159,973 square kilometers.
So, 
x=79750
Area of Country A = x+473=79750+473=80223 sq.km.
Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
Answer:
1
Step-by-step explanation:
LCD = 1
Equivalent Fractions with the LCD
9 = 9/1
8 = 8/1
6 = 6/1
5 = 5/1
Solution:
Rewriting input as fractions if necessary:
9/1, 8/1, 6/1, 5/1
For the denominators (1, 1, 1, 1) the least common multiple (LCM) is 1.
LCM(1, 1, 1, 1)
Therefore, the least common denominator (LCD) is 1.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
9 = 9/1 × 1/1 = 9/1
8 = 8/1 × 1/1 = 8/1
6 = 6/1 × 1/1 = 6/1
5 = 5/1 × 1/1 = 5/1
Answer:
B i think
Step-by-step explanation:
The product of 1 and any number is the number (hence why it is most likely b). But instead of it being 4, it would be -4 because multiplying a negative by a positive results in a negative.
5 x 3 = 15 + 1 = 16 feet
16 x 8 = 128 feet
128 / 3 = 42 yards 2 feet
Hope this helps!! :)
