Answer:
CB = 5, 
Step-by-step explanation:
Assuming that the marks next to angle D mean that
, then there is enough information to conclude that the two right triangles are congruent (HA theorem--hypotenuse/angle).
Then all the corresponding parts of the two triangles are congruent, including segments BA and BC, making them the same length.
4x + 1 = 9x - 4
Solving for x,
1 = 5x - 4
5 = 5x
1 = x
Pluggint x = 1 into the two expressions reveals that the length of segment CB is 5.
The two small angles at D are congruent, so
.
Answer:
x = 52/3
Step-by-step explanation:
3x / 7x = (3x+7) / (3x+7+5x-8)
3/7 = (3x+7)/(8x - 1)
Cross multiply
7(3x+7)=3(8x-1)
21x + 49 = 24x - 3
-3x = -52
x = 52/3
1) Subtract 6x from both sides. -3y= -9-6x
<span>2) Divide both sides by -3. y= 3+2x </span>
<span>2) Put it in slope-intercept form: y=mx+b. y= 2x+3 </span>
<span>Final answer: y=2x+3</span>
Answer:
a.
Step-by-step explanation:
Each system has a different purpose. one for the cost, and one for the pounds.
x+y=12 is for the pounds
since each pound of dried fruit cost $6 and each pound of nuts cost $2, and you can only spend $40,
6x+2y=40
