Answer:

c = -25

Step-by-step explanation:

First, simplify the constants on the left side of the equation

-2c-6-9=35

-2c-15=35, Add 15 to both sides

-2c-15+(15) = 35+(15)

-2c=50 Now, divide both sides by -2 to isolate the variable c

-2c/(-2) = 50/(-2)

c = -25 And here is the answer.

vlabodo [156]

Answer: 4 cakes left in all.

Step-by-step explanation:

Given: Cakes left on first day= $2\frac{3}{4}=\frac{11}{4}$

Cakes left on second day = $1\frac{1}{4}=\frac{5}{4}$

The number of cakes left in all= $\frac{11}{4}+\frac{5}{4}$

⇒The number of cakes left in all= $\frac{11+5}{4}=\frac{16}{4}$

Therefore, The number of cakes left in all=4

Please answer and explain #17 :)

IRINA_888 [86]

Answer:

Solution given:

we have

m<PTQ=m<RTS

x+20=3x+12.

20-12=3x-x

$\frac{8}{2}$

now

16.m<PTQ=x+20=4+20=24°

17.

again

m<PTR+m<PTQ=180°[supplementary]

m<PTR=180°-24°=156° is your answer

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equ

irga5000 [103]

I hope the equation will be 2000=16000(1-r)^t because t is missing in the equation which we need to find.

Given rate: r= 35%= 0.35.

So, first step is to plug in 0.35 for r in the given formula to get the value of t.

Hence, the equation will be:

2000=16000(1-0.35)^t

2000=16000(0.65)^t (By subtraction)

2000/16000= 16000(0.65)^t /16000 (Dividing each sides by 16000)

0.125 = 0.65^t (By simplifying).

log 0.125 = log 0.65^t (Taking log each sides to isolate t).

log 0.125 = t log 0.65 (By applying the log property).

$\frac{log 0.125}{log 0.65} =t$ (Dividing each sides by log 0.65)

-0.903/-0.187 =t

t= 4.83

t= 5 ( Rounded to nearest integers)

So, Devon's car is 5 years old.

Find the x- and y- intercepts of the graph of the linear equation 3x-6y=2

bogdanovich [222]

- Put x=0, you would get the y-intercept, so you got one point which would be (0,#)

- Put y=0, you got where the graph would touch\cross\intersect the x-axis, and the other point is (#,0)

to get x-intercept:
y=0:
3x=2 >> x=2/3

to get y-intercept:
x=0:
-6y=2 >>> y = -1/3
