Use proportions to solve this problem
Solve for "x"
x = 
Simplification
x = 
Result
x = 15
1.3/13(if you mean jacks queens and kings)
2.1/52
3.1/2
4.1/13
5.1/4
3*2=6
2 2/3
7*2=14
2 5/7
the answer is B)
good luck
Answer:
x = 5
y = 1
Step-by-step explanation:
So move 2y from the second equation to the other side of the equals sign
2x +3y = 13
x = 3 + 2y
From here substitute X into the first equation
2(3 + 2y) + 3y = 13
Distribute
6 + 4y +3y = 13
Combine like terms and solve for y
7y = 7
y = 1
insert result into the original equation.
x-2(1) = 3
x - 2 = 3
x = 5
insert into other equation to check work
2(5) + 3(1) = 13
10 + 3 = 13 correct
Formula for surface are: 2(lw+wh+lh) where l is length, w is width and h is height.
Plug in for 1 - 3
1:
2((16)6 + (6)5 + (16)5)
2(96 + 30 + 80)
2(206)
412 ft²
2:
2((13)5 + (5)6 + (13)6)
2(65 + 30 + 78)
2(173)
346 mm²
3:
2((20)4 + (4)15 + (20)15)
2(80 + 60 + 300)
2(440)
880 in²
