4 (.05) x +( .10)x =180
.20x + .10x = 180
.30x = 180
X= 6
So. 4 times 6 = 24 nickels and 6 dimes = 180 cents
All angles in a quadrilateral add to 360
x is supplementary to that other angle, call it y
the angles inside are 40, 80, 110 and y
40+80+110+y=360
230+y=360
minus 230 both sides
y=130
that is supplementary to x (adds to 180)
x+y=180
x+130=180
minus 130 both sides
x=50
x=50 degrees
Answer:
7h+3=-11?
then h=-11-3 divided by 7
Step-by-step explanation:
As there is no graph attached so you have to done it yourself, Steps provided below for making it easier.
- Observe the graph, whether it's a barchart/histogram/Piechart .
- Then find 270 in the graph.
- Check respective y co-ordinates .
Done!You found the answer
