When using substitution, what does the equation look like after the 1st step ?

y = 6x +3

x + 2y = 5

Answers

Answer:

Step-by-step explanation:

y = 6x + 3   --------------(I)

x + 2y = 5       -------------(II)

substitute y = 6x + 3 in equation (II)

x + 2*(6x + 3) = 5

x + 2*6x + 2*3 = 5

x + 12x + 6  = 5

Points b d and f are midpoints of ten sides of ace ec=44 df=25 find ac

Answers

Answer:

The length of AC is;

C. 50

Step-by-step explanation:

By the midpoint of a triangle theorem, we have that a segment that spans across and intersects with the midpoints of two sides of a triangle is equal to half the length of the third side and parallel to the length of the third side

The given parameters are;

The midpoints of ΔACE are B, D, and F

The length of EC = 44

The length of DF = 25

Therefore, we have;

Given that DF is a midsegment of triangle ΔACE, then DF ║ AC and

the length of DF = (1/2) × AC the length of AC

∴ The length of AC = 2 × The length of DF

The length of DF = 25

∴ The length of AC = 2 × 25 = 50

The length of AC = 50

What is the relationship between the corresponding angle bisectors BD and XZ?

Answers

Answer:

If the two triangles are equivalent, then all the measures of triangle 2 are k times the measures of triangle 1.

This means that:

BC = k*XY

here we know that:

BC = 8

XY = 20

then:

8 = k*20

8/20 = k

0.4 = k

Then we also will have the relation:

BD = 0.4*XZ

and we know that:

BD = 6

then:

6 = 0.4*XZ

6/0.4 = XZ

15 = XZ

Answering the question, the relationship between the corresponding angle bisectors is:

BD/XZ = 6/15 = 0.4

Step-by-step explanation:

1.a: there are 6 cups per can so if you multiply it for each can, you get the cups.

1.b: there are 16 cups per gallon. Packs of 4 cans so in total, there are 24 cups in total. So there are 1.5 gallons per pack. 1.5x6 = 90 so that's no enough. 1.5x7 = 10.5. That's more than enough but she can't split the pack so she needs to buy 7 packs.
