Answer:
The answer is the option A

Step-by-step explanation:
we know that
The lateral area of a right rectangular prism is equal to

where
P is the perimeter of the base
h is the height of the prism
Find the perimeter


substitute in the formula

< CAD = 100....if u add < ACB + < CBA u get < CAD
================
< DAB = 125 and < ACB = 30
if DAB = 125.....then BAC = 180 - 125 = 55
and all 3 interior angles of a triangle = 180
< BAC + < ACB + < ABC = 180
55 + 30 + < ABC = 180
85 + < ABC = 180
< ABC = 180 - 85
< ABC = 95 <===
Answer: <em>
</em>
Step-by-step explanation:

The complete exercise is:"A gardener has 27 tulip bulbs, 45 tomato plants, 108 rose bushes, and 126 herb seedlings to plant in the city garden. He wants each row of the garden to have the same number of each kind of plant. What is the greatest number of rows that the gardener can make if he uses all the plants?"</em></h3><h3 />
The first step to solve the exercise is to find the Greatest Common Factor (GCF) between 27, 45, 108 and 126.
You can follow these steps in order to find the GCF:
1. You must decompose 27, 45, 108 and 126into their prime factors:

2. You must multiply the commons with the lowest exponents. Then:
<em>
</em>
Therefore, the greatest number of rows that the gardener can make if he uses all the plants is:

Answer:
x=7.5
y=1.5
Step-by-step explanation:

subtract x from both sides




combine like terms

subtract 1.8 from both sides

divide both sides by 0.3
x=7.5


y=1.5
