Answer:
30 centimeters^2
Step-by-step explanation:
The area of a triangle can be found using the following formula.
A= (b*h)/2
In this triangle, the base is 12 cm. The height is 5 cm, since it forms a right angle with the base.
b= 12 cm
h= 5 cm
A= (12 cm * 5 cm) / 2
Solve inside the parentheses first. Multiply 12 cm and 5 cm.
A= (60 cm^2) / 2
Divide 60 cm^2 by 2
A= 30 cm ^2
The area of the triangle is 30 square centimeters.
X-y=2 (*-2) --> -2x+2y=-4
2x+3y=14

y=2
Answer:
8x+30=334
Step-by-step explanation:
X= the amount of cups he got and 30 is the initial fee so he only has to pay that once
Answer:
x=-26
Step-by-step explanation:
Subtract 45 from both sides.
-85-45=5x
Simplify -85-45 to -130
-130=5x
Divide both sides by 5.
-130/5=x
Simplify 130/5 to 26
-26=x
