For this case we must find the value of the variable of the following equation:

Subtracting
from both sides:

Subtracting 4 from both sides:

Multiplying by 6 on both sides:

Answer:

Answer:
The proportion is
=
, and the length of the unknown side is
or 27.22 approximately rounded to the nearest hundredth.
Step-by-step explanation:
Since the triangles are similar, the proportion of corresponding sides are equal. The pairs of corresponding sides in these triangles which we'll use to solve it are LK, KE, MK, and KF. LK and KE are corresponding sides, and their proportion is
. MK and KF are corresponding sides, and their proportion is
in which x represents the missing side. The proportions are equal, so
=
. Multiply both sides by 84 to isolate the variable, and you'll get
, which is
or
.
Answer:
The jar contains 132 grams of zinc
Step-by-step explanation:
zinc to copper = 3 : 19
New equivalent weights
zinc to copper = x : 836
Now, let us solve for x as follows

the jar contains 132 grams of zinc
To check if the answer is accurate, the answer gotten when the weight of zinc is divided by copper will be the same for both the old and new ratios:
old ratio: 3 ÷ 19 = 0.158
new ratio: 132 ÷ 836 = 0.158
