Answer:
So the exchange rate is that each dollar is worth 70.4 yens.
Step-by-step explanation:
We have that:
1 euro is priced at $1.25
1 euro will also buy 88 Japanese yen
This also means that:
$1.25 is priced at 88 Japanese yen
How much is the cross rate between the yen and the dollar (yen per dollar exchange rate)?
How much yens is 1 dollar?
This can be solved by a simple rule of three.
$1.25 - 88 yen
$1 - x yen
So the exchange rate is that each dollar is worth 70.4 yens.

System of Equations
Step-by-step explanation:
A system of equations refers to a number of equations with an equal number of variables. We will only look at the case of two linear equations in two unknowns. The bracket on the left indicates that the two equations are intended to be solved simultaneously, but it is not always used.
Triangles
ABC - AB=2.5, BC=1.5, CA=2 (5: 3: 4)
ADC - AC=2, CD= 1.2, DA= 1.6
BCD - BC=1.5, BD = 0.9, DB = 1.2
Area
ABC = 1/2 *AC * CB = 1/2 *2 * 1.5 = 1.5 m^2
ADC = 1/2 *AD * DC = 1/2 * 1.6 * 1.2 = 0.96 m^2
BCD = 1/2 *BD * DC = 1/2 * 0.9 * 1.2 = 0.54 m^2
