U have to multiply 16.3 and $5.29 and your answer is $80
Find x you mean?
substract both side by 2x
5x=-35
divide both side by 5
x=-7
->D
Answer:
x = 9
Step-by-step explanation:
Distribute
2x+2*5=3x+1
2x+10=3x+1
Subtract 3x from both sides
-x+10=1
Subtract 10 from both sides
-x=-9
Multiply both sides by -1
x=9
Answer:
D) 21
Step-by-step explanation:
The formula for finding the area of a triangle is A = 1/2 B x H. So, A = 1/2 (7)(6).
A = 1/2 (42)
A = 21.
So the area of the shaded region is 21 square units.
Answer:
b. 3x - (5y -7)
Step-by-step explanation:
Let x represent "a number". Let y represent "another number."
The "3 times a number" is represented by 3x.
And "5 times another number less 7" is represented by 5y -7.
The difference between these quantities is the second subtracted from the first:
... 3x - (5y -7) . . . . matches selection b.
