A= -2+(-3)×(-8+4)

-2+(-3)×(-4)

-2+12=10

B=-9+8×7+(-12)

-9+56-12=35

C=8-2= -4

D=8÷2=4

E= -4-35= -39

A bottle contains 20fluid ounces of lotion and sells for $5.80.The 20-fluid -ounce bottle contains 125% of the lotion in the nex
daser333 [38]
If the 20 fl.oz bottle contains 125% of the next smallest size, the next smallest bottle should be 4/5 of the 20fl. oz bottle.
That means the smaller bottle has 16 fl. oz (you can check it, multiply 16 by 1.25 and you get 20).
Next, you can find the price as dollars per fluid ounce.
The bigger bottle will be: 5.8/20=$0.29
The smaller bottle: 5.12/16=$0.32
In this case, the larger bottle is the better buy because you pay less per fluid ounce of lotion.

This is the question:
MrRissso [65]

Answer:

A)

y =  \frac{10}{3}x

B) 240 pages

Step-by-step explanation:

From the table, he can read 20 pages in 6 minutes and 15 paged in 50 minutes.

The unit rate can be found using

m =  \frac{change \: in \: y}{change \: in \: x}

m =  \frac{50 - 20}{15 - 6}

m =  \frac{30}{9}  =  \frac{10}{3}

Using the point (6,20) and the unit rate we can find the equation using

y-y_1=m(x-x_1)

y - 20 =  \frac{10}{3}(x - 6)

y=\frac{10}{3}x - 20 + 20

y =  \frac{10}{3}x

B) When x=72 minutes we substitute

y =  \frac{10}{3} \times 72

y = 10 \times 24 = 240

Find the value of x in the triangle shown below.
Scrat [10]

This is a isoceles triangle so base angles will be equal.

Therefore

ATQ

55 + 55 + x = 180

110 + x = 180 (Angle Sum Property)

x = 180 - 110

x = 70

Therefore x° = 70°
