Answer: The numbers are 10.8 and 46.2.
Step-by-step explanation: The sum of two numbers is 57.
x + y = 57
Assume x is the larger number.
x - 3 = 4y
x = 4y + 3
Use subsitution.
4y + 3 + y = 57
y = -4y - 3 + 57
y = -4y + 54
5y = 54
y = 10.8
Plug in y.
x + 10.8 = 57
x = 46.2
Check.
46.2 - 3 = 4(10.8)
43.2 = 43.2
189
358-169=189
Mark brainliest please
10*7*5=350 in3, the volume of 1 brick
14,000 in3 is the volume of all the concrete
Let X=the number of bricks
350*X=14000
X=14000/350
X=40 bricks
Answer: A
golden ratio approximately equals:
(1+sqrt(5))/2=1.618
5/3=1.667
7/5=1.4
10/8=5/4=1.25
17/11=1.545
Change everything to decimal form and see what is closest.
So we can see that the photograph size of 5x3 is the best choice as it is the closest in size to the golden ratio.
Any questions at all please feel free to ask! Thank you so much!
