two numbers have ratio 12:5.their differnce is 49.find the two numbers .
Answer:
84 and 35
Step-by-step explanation:
12 - 5 = 7
12(7) = 84
5(7) = 35
Two numbers: 84 and 35
Step-by-step explanation:
Let the two numbers be x and y
Given:
Ratio of two numbers= 12:5
Difference between two numbers= 49
So, we need to find the difference between its ratio in order to get two numbers.
12 - 5 = 7
Thus, simply on multiplying the number so obtained after subtraction we will get:
12 * (7) = 84
5 * (7) = 35
Also, the difference is given which is 49
so, we can confirm it by finding the difference between the numbers obtained which is 84-35=49
Therefore, the two numbers are 84 and 35.

Show work, if possible. Thanks❤️
Answer:
I'm doing some of these questions now in my math class. I think it's D) 44 sorry if I'm wrong tho
Answer:
Step-by-step explanation:
Since the hypotenuse is 44 and the two sides are equal to FT we can say
2(FT)^2=44^2
FT^2=968
FT=22(2^(1/2))
So C is the correct answer.

Find the values of x, y and z.
Answer:
X = 53 degrees
Y = 74 degrees
Z = 53 degrees
Step-by-step explanation:
So if you knew that all angles in triangles add up to 180 degrees. You first want to find Y. 180 - 36 - 70 is equal to 74. So, Angle Y is 74 degrees. Line XYZ is a line that has a 180 degree on there. So 180 - 74 and divide that by 2 to find X and Z. 180 - 74 is 106. 106/2 = 53. Therefore, X and Z are 53 degrees, Y is 74 degrees.
Y =74
Step-by-step explanation:
Add the number till u get 180

Please solve step by step to help me understand. Thanks!
Answer:
x=6, AT=45, MT=15, MA=45
Step-by-step explanation:
Because it is isosceles, MA=AT, so 8x-3=5x+15, solve for x and then plug it into the equations.

what is 11/4-3/8= what is it or get me the right answer
Answer:
2 3/8 is the answer
Step-by-step explanation:
11/4 - 3/8
We will find the LCM of 4 and 8, which is 8.
We will do 11/4*8, which 8/4 = 2 and 2*11 = 22
Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3
So the answer will be 22-3 = 19
8 = 8
Mixed Fraction = 2 3/8
