I added a screenshot with the complete question
Answer:x = 3
y = 9
Explanation:1- getting the value of x:We are given that:
side AB is congruent to side DF. This means that:
AB = DF
3(2x+10) = 12x + 12
6x + 30 = 12x + 12
12x - 6x = 30 - 12
6x = 18
x = 18/6
x = 3
2- getting the value of y:We are given that:
side BC is congruent to side FG. This means that:
BC = FG
2y + 12 = 2(2y-3)
2y + 12 = 4y - 6
4y - 2y = 12 + 6
2y = 18
y = 18/2
y = 9
Hope this helps :)
Answer:
length of the third side may be either 3.4 m or 2.8 m.
Step-by-step explanation:
Measure of two sides of a right triangle are 1.4 m and the other side is 3.1 m.
then we have to find the measure of third side.
If the third side of the triangle is its hypotenuse then
(Third side)² = (1.4)² + (3.1)²
Third side = 
= 
= 
= 3.4 m
If the third side is one of the perpendicular sides of the triangle and 3.1 m is hypotenuse, then
(Third side)² + (1.4)² = (3.1)²
(Third side)²= (3.1)² - (1.4)²
Third side = 
= 
= 
= 2.76 m
≈ 2.8 m
Therefore, length of the third side may be either 3.4 m or 2.8 m.
Answer:
We need to start with 5 kg of mushrooms
Step-by-step explanation:
The total of the dried mushrooms = mushrooms * percentage of weight kept
percentage of weight kept = 1- 80% = 20 %
We want 1 kg of dried mushrooms. Substitute in what we know
1 kg = mushrooms * 20%
1 kg = mushrooms * .2
Divide each side by .2
1 /.2 = mushroom *.2 /.2
5 kg = mushrooms
We need to start with 5 kg of mushrooms
