Answer:
16sqrt(3) units²
Step-by-step explanation:
This shape consists of 6 congruent triangles
Each angle = (6-2)×180/6 = 120
These are 6 equilateral triangles
6(½ × 8 × 8 × sin(60)) = 16sqrt(3) units²
Well she would need about 11.5 gallons of gas times 1.89 is $21.73 hope this helps
Answer:
x=-9,y=-4
Step-by-step explanation:
2x-3y=-6...(1)
-2x-2y=26...(2)
To solve we will have to eliminate one of the given variables, the variable to be eliminated is x
And it can be done by adding up (1) and (2)
It gives
-5y=20
Divide both sides by-5
y=-4
Then substitute the value of y into (1)
2x-3(-4)=-6
2x+12=-6
Substrate 12 from both sides
2x=-18
Divide both sides by 2
x=-9
Therefore x gives -9 and y gives-4
Answer:
6,4
Step-by-step explanation:
I'm not sure if 4 is correct but 6 definitely is. I hope this helps
Answer:
x=12 and
(9*12)-10=98
(5*12)+38=98
both angles are = 98
Step-by-step explanation:
do this :
9x - 10 = 5x + 38
( - 5x from both sides)
4x - 10 = 38
(add 10 to both sides)
4x = 38+10
4x=48
(divide by 4)
x=48/4
= 12
substitute into the equations:
(9*12)-10
(5*12)+38
