Answer:
The solution is (8, -1).
Step-by-step explanation:
2x + 4y = 12..........(1)
y = 1/4x – 3 ..........(2)
Substitute y = x - 3 in equation (1):
2x + 4(1/4x - 3) = 12
2x + x - 12 = 12
3x = 24
x = 8.
Now substitute for x in equation (2):
y = 1/4 *8 - 3
y = -1.
4.20 divided by 4.00= 1.05
turn decimal into percentage by times 100
1.05 times 100= 105%
Answer:
The measure of angle A is 115°
Step-by-step explanation:
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
∠C+∠A+∠B=180°
substitute values and solve for x
x°+(3x-35)°+(x-35)°=180°
5x°=180°+70°
x=250°/5=50°
Find the measure of angle A
∠A=(3x-35)°
substitute the value of x
∠A=(3(50)-35)=115°
The answer is C. 4 obtuse angles could not make a 4 sided figure such as a parrallelogram. 4 acute angles is not possible for creating parallelograms either.
