Answer:
Step-by-step explanation:
4)
Given the expression
a+b-c
substituting the values in the expression
a+b-c = 4.1+5.7-0.3
= 9.8 - 0.3
= 9.5
5)
Given the expression
10-(a+b)
substituting the values in the expression
10-(a+b) = 10 - (4.1+5.7)
= 10 - 9.8
= 0.2
6)
Given the expression
b-c+2
substituting the values in the expression
b-c+2 = 5.7 - 0.3 +2
= 5.4 + 2
= 7.4
Answer:
for the second questio it is certainly The last choice D
Step-by-step explanation:
Answer:
142.96 dollars
Step-by-step explanation:
The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .
And given perimeter is 252 meters .
Perimeter is the sum of all sides. So we get

Dividing both sides by 21

So the sides are

220% of the goal. This is because 500 cans would be 200% but since it’s 550, the extra 50% would equal to 220%.
