Answer:
d, triangular pyramid
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
4(5x-2)=2(9x+3) do everything in the parentheses
20x-8=18x+6
+8 +8
20x=18x+14
get X by itself by adding same terms
20x=18x+14
-18x -18x
2x=14 divide
/2 /2
X=7
Its the first One i think
I'm pretty sure it's 2.166667 miles per hour. Since its every hour you just need to divide that by 1 which is 2 1/6. And 2 1/6 in decimal form is 2.166667.
Answer:
- rotation 90° CCW
- translation 2 units upward
Step-by-step explanation:
It can help to draw a diagram.
In the attached diagram, the red triangle (RST) is the original, the purple one (ABC) is after rotation CCW by 90°, and the blue one (R'S'T') is after that is translated upward 2 units. R'S'T' is the final position.
Since RS and R'S' are oriented 90° with respect to each other, clearly a CCW rotation of that amount is required. The trick is to figure out which direction the translation occurs.
The translation can be done before or after the rotation. If done before, it needs to be 2 units to the right (not a choice). If done after, it can be 2 units up, as in this drawing.
