Answer:1/3
Step-by-step explanation:
Answer:
x = 6
y = - 14
Step-by-step explanation:
- -2x × 2 + 10 = - 2x - 2
- x = 6
- y = -2 × 6 - 2 = - 14
We can set up a proportion, and let x be the amount 16kg would cost: 14/154=16/x. We simplify 14/154 = 1/11. Next, we cross-multiply to get (1)(x)=(16)(11), so x=176. Therefore, 16kg of apples cost $176.

Variation Constant: k = 7/6
y = 245/6 when x = 7 and z = 5
====================================
Explanation:
"y varies jointly as x and z" means that y = kxz
We have (x,y,z) = (4,14,3) as one triple, so,
y = kxz
14 = k*4*3
14 = 12k
12k = 14
k = 14/12
k = 7/6 is the variation constant
The equation goes from y = kxz to y = (7/6)xz
----------------
Plug in x = 7 and z = 5 to find y
y = (7/6)xz
y = (7/6)*7*5
y = (7/6)*(7/1)*(5/1)
y = (7*7*5)/(6*1*1)
y = 245/6
Answer:
180 cm2
Area of a polyhedron:
15(=base)x12(=height)
=180cm2
btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.
If so, your ''area of parallelogram'' is 15cm2 since your question is hecking weird.
Btw it's 15cm2 not 15
Please check ur question b4 u ask
