CE = CD + DE;
17.1 = CD + 8;
CD = 17.1 - 8;
CD = 9.1;
Answer:
600
Step-by-step explanation:
0+.80x=60+.70x
-.70x=60-.70x
.10x=60
÷.10=÷.10
C=600
0+.80(600)=480
60+.70(600)=480
Answer:
The solution of the equation 9x=7(x+2) is:
Option D) 7
Step-by-step explanation:
9x=7(x+2)
Eliminating the parentheses applying distributive property:
9x=7(x)+7(2)
Multiplying:
9x=7x+14
Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:
9x-7x=7x+14-7x
Subtracting:
2x=14
Solving for x: Dividing both sides of the equation by 2:
2x/2=14/2
Dividing:
x=7
Solution: x=7 (option D)
Answer:
m<DEF = 8y - 6
Step-by-step explanation:
Given that: DEG = 
, and FEG = 
.
The given triangle is an isosceles triangle with sides DE ≅ DF.
But,
m<DEF = DEG + FEG
= +
= 3y + 4 + 5y - 10
= 8y - 6
m<DEF = 8y - 6
Therefore, the measure of < DEF is 8y - 6.
