Answer:
x = 30.
Step-by-step explanation:
For the triangles to be similar corresponding sides must be in the same ratio.
So 50/ 75 = x / 45
75x = 50*45
x = 50* 45/75
= 2 * 45 / 3
= 30. (answer).
Answer:
5 x 3 1/2 x 1 1/2
5 x 7/2 x 3/2 = 26 1/4, in decimal form: 26.25
Multiply across, but first make it all improper fractions.
If you divide 100 by 25 you will get 4. Then you multiply 4 and 2, which
will get you 8. So, it will take her 8 weeks to pay her parents.
#4 a reflection across the x-axis is the only correct answer , the other ones aren’t correct .
Answer:
The integers are (x, y) = (40, 8).
Step-by-step explanation:
x = 5y
xy = 320
Substitute the first equation into the second equation.
(5y)(y) = 320
5y^2 = 320
y^2 = 64
y = 8 (y must be positive)
The integers are (x, y) = (40, 8).
