Answer:
17-1/4y
Step-by-step explanation:
Answer:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
![\left \{ {{x+y = 20 \atop {55x+60y=1125}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%2By%20%3D%2020%20%5Catop%20%7B55x%2B60y%3D1125%7D%7D%20%5Cright.)
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that ![x=15](https://tex.z-dn.net/?f=x%3D15)
The correct answer is -2/3
Because the dot is 4 steps left of 0, and there are 6 steps from 0-1
So its -4/6
And reducing to its lowest term, its -2/3
You’re welcome :)
You have to multiply the 2 numbers together.
0.3 x 0.4
0.12
Answer:
The correct option is 3.
Step-by-step explanation:
Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.
J = 90°, J' = 90°
K = 65°, K' = 65°
L = 25°, L' = 25°
In a rigid transformation the image and pre-image are congruent. Reflection, translation and rotation are rigid transformation.
In a non rigid transformation the image and pre-image are similar. Dilation is a non rigid transformation.
In a rigid or a nonrigid transformation, the corresponding angles are same. If the corresponding sides are same, then it is a rigid transformation and if the corresponding sides are proportional, then it is a non rigid transformation.
It can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures.
Therefore option 3 is correct.
