Answer:
Step-by-step explanation:
try using each answer choise to find your answer it shoud equal 180 because all of the triangles equal that.
Answer:
So the numbers are 12 and -3.
Step-by-step explanation:
In order to solve this problem we will attribute variables to the numbers, the first one will be "x" and the second one will be "y". From the first sentence we know that the subtraction of the two numbers is equal to 15, so we have:
x - y = 15
Then the problem states that one-third of the sum of the number is equal to one quarter of the first number, so we have:
(1/3)*(x+y) = x/4
Since we now have two equations and two variables we can solve for x and y. From the first equation we have:
y = x - 15
Using this expression for the value of y in the second equation:
(1/3)*(x + x - 15) = x/4
(1/3)*(2*x - 15) = x/4
2*x - 15 = 3*x/4
2*x - 3*x/4 = 15
(8*x - 3*x)/4 = 15
5*x/4 = 15
5*x = 60
x = 60/5 = 12
y = x - 15 = 12 - 15 = -3
So the numbers are 12 and -3.
The width of the H is 1/2 + 1 + 1/2 = 2 inches. Since the borders are the same on all sides, they are (4 -2)/2 = 1 inch wide all around. That means the height of the H is 5 -2*1 = 3 inches.
The area of the H is 2*(1/2*3) +(1/2*1) = 3 1/2 square inches.
The area of the overall painting is 4*5 = 20 square inches.
Then the fraction that is beige is
.. (20 -3.5)/20 = 16.5/20 = 82.5/100 = 82.5%
_____
Each of the actual dimensions is 6 times that shown in the calculation above. You could say we chose to factor out the 6s and cancel them in the ratio.
The Answer Is 600 Because The Number To The Right Is Less Than 4
