Answer:

It means that for every 4cm on an axis, it counts as 1 unit.

So for instance, you have a 24cm axis to work with. You would have a total of 6 units on the axis, because each unit is 4cm.

ABCD diagonals intersect at E. If m∠BAC=4x+5 and m∠CAD=5x-14, then find m∠CAD.

Travka [436]

Answer: m∠CAD = 81°

Step-by-step explanation: Diagonal is a line that unites opposite sides.

ABCD is a prallelogram. One property of diagonal in a parallelogram is it separates the parallelogram in 2 congruent triangles.

The figure below shows ABCD with its diagonals.

Since diagonal divides a parallelogram in 2 congruent triangles, it means the internal angles are also congruent. So

m∠BAC = m∠CAD

4x + 5 = 5x - 14

x = 19

Then, m∠CAD is

m∠CAD = 5(19) - 14

m∠CAD = 81

The angle m∠CAD is 81°.

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.

Katyanochek1 [597]

Answer:

Sheet = $12
Blanket = $17

Step-by-step explanation:

Let the cost of a sheet be s and cost of a blanket be b

2s + b = 41
s + 4b = 80

From the first equation we get:

b = 41 - 2s

Substitute in the second equation

s + 4*(41 - 2s) = 80
s + 164 - 8s = 80
7s = 84
s = 12

Then

b = 41- 2*12 = 17
