Answer:
m<C = 66°
Step-by-step explanation:
Perpendicular bisector, AB divides angle CAD into two equal parts. Therefore:
(5x + 9)° = (7x + 3)°
Solve for x
5x + 9 = 7x + 3
Collect like terms
5x - 7x = -9 + 3
-2x = -6
Divide both sides by -2
x = 3
✔️m<C + m<CBA + m<BAC = 180° (sum of triangle)
m<C + 90° + (7x + 3)° = 180 (substitution)
Plug in the value of x and solve
m<C + 90 + 7(3) + 3 = 180
m<C + 90 + 21 + 3 = 180
m<C + 114 = 180
m<C = 180 - 114 (Subtraction property of equality)
m<C = 66°
Easy ! you first subtract the 5 to itself and to the 17, so 5 - 5 and 17 - 5. your equation should look like 3g = 12. since we need to isolate the variable (g) we need to divide 3 by itself and 12 by 3, so 3 ÷ 3 and 12 ÷ 3. now you have g = 4!
Answer: No
Step-by-step explanation: the ratio 3:6 reduces to one half
the ratio 6:3 reduces to 2 because division cannot be interchangeable
Answer:
y=0.05x+0.25
Step-by-step explanation:
.25/5 is slope---- divide
.25 is y-int
Answer:
$50.1
Step-by-step explanation:
If you plug 40 in for x in the equation y=0.94x+12.5 then you should get 50.1 for y.
