Answer:
x ≤ 1
Step-by-step explanation:
3x+4≤ 7
3x + 4 - 4 ≤ 7 - 4
3x≤3
x ≤ 1
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add
50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750
750 grams of water
Answer:

Step-by-step explanation:
To find the equation of this circle, we must know the center and the radius.
We can find the radius by dividing the value of the distance formula by 2 (since
):

We can then find the center of the circle by averaging the coordinates:


Then, we substitute these values into the equation of a circle:

Answer:
x = 72
Step-by-step explanation:
For all polygons, the exterior angles add up to 360°
Since a pentagon has 5 exterior angles, you do
angle = 360 ÷ 5 = 72
here's a picture so you understand better
Answer:
No
Step-by-step explanation:
If you where to simplify them it would be 25c + 6 and 25 + 30c
