Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
Answer:
second option
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
∠ 1 and 33° form a straight angle and are supplementary, thus
∠ 1 = 180° - 33° = 147°
----------------------------------
The third angle in the triangle on the left is
180° - (33 + 47)° = 180° - 80° = 100°, thus
∠ 2 = 180° - 100° = 80°
--------------------------------------
∠ 2 and the angle in the triangle form a straight angle and are supplementary,
angle = 180° - 80° = 100°
The third angle in the triangle on the right is
180° - (100 + 48)° = 180° - 148° = 32°, thus
∠ 3 = 180° - 32° = 148° ( straight angle )
Thus
∠ 1 = 147°, ∠ 2 = 80°, ∠ 3 = 148°
I am pretty sure it’s an inch or A but if i’m wrong sorry
Answer:
yes
Step-by-step explanation:
anything with 10^n multiplied by a number from 0 to 10 is
Answer:
x-intercept is (3.6,0)
y-intercept is (0,-2)
Step-by-step explanation:
Given the linear graph: -5x + 9y = -18
X-intercept is when y=0;
-5x + 0 = -18
-5x = -18
x = 18/5 = 3.6
The x-intercept therefore is (3.6,0)
Y-intercept is when x = 0;
0 + 9y = -18
9y = -18
y = -18/9 = -2
Therefore y-intercept is (0,-2)
