densk [106]

Answer:2.19 monthd

Step-by-step explanation:

Cris borrowed money from her brother 6 months ago. She now owes him 56.50

Let x= original money borrowed from her brother 6 months ago

She has not borrowed and she is paying 15.75 on her debt each month for the last 6 months. This means in the past 6 months,she has paid 15.75×6= 94.5

She now owes him 56.50. This means original money,x-56.50 =94.5

x = 94.5+56.50=151

If she now increases her monthly payment to 25.75, let the number of months be y, she will pay 25.75y in y months

25.75y =56.50

y =2.19 months

kherson [118]

Answer:

16.875 spiders

Step-by-step explanation:

Given

Let

B = Beetles

C = Birds

S = Spiders

So, we have:

B = C = S --- equal amounts

6B + 2C + 8S = 270 --- the legs

Required

The number of spider

Since she has an equal amount of B, C and S;

The expression can be written as:

6B + 2C + 8S = 270

6S + 2S + 8S = 270

16S = 270

Solve for S

S = \frac{270}{16}

S = 16.875

<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>

AB and BC form a right angle at point B. If A = (-3,-1) and B = (4,4), what is the equation of BC
m_a_m_a [10]

Answer:

y=-1.4x+9.6

Step-by-step explanation:

If A = (-3,-1) and B = (4,4),  the slope of AB is

\text{Slope}_{AB}=\dfrac{-1-4}{-3-4}=\dfrac{-5}{-7}=\dfrac{5}{7}

Two perpendicular lines have slopes that have product of -1:

\text{Slopee}_{AB}\cdot \text{Slope}_{BC}=-1\\ \\\dfrac{5}{7}\cdot \text{Slope}_{BC}=-1\\ \\\text{Slope}_{BC}=-\dfrac{7}{5}=-1.4

The equation of the line BC with slope -1.4 and passing through the point B(4,4) is

y-4=-1.4(x-4)\\ \\y-4=-1.4x+5.6\\ \\y=-1.4x+9.6

ABCD is a parallelogram. Find the measure of angle ABC.​
iVinArrow [24]

Answer:

∠ABC = 50°

Step-by-step explanation:

Since this is a parallelogram, opposite angles are congruent.

Therefore, ∠D ≅ ∠B

∠D = 38° + 12°

∠B = 38° + 12°

∠B = 50°

∠ABC = 50°
