A store is selling T-shirts. Which is the best deal?

8 for $26
5 for $30
4 for $15
12 for $39
10 for $45

Answers

divide cost by quantity. The lowest rate is the best buy:

26/8 = 3.25 each

30/5 = 6.00 each

15/4 = 3.75 each

39/12 = 3.25 each

45/10 = 4.50 each

The 8 for 26 and the 12 for 39 are both the same price each and are the better buys.

Step-by-step explanation:

You spend 264 dollars on clothes. Shirts cost 24 and pants cost :2 you buy a total of 9 items

Answers

EQUATIONS:

24x + 32y = 264

x + y = 9

x is shirts, y is pants

SOLVING by substitution:

x = 9 - y

24(9 - y) + 32y = 264

216 - 24y + 32y = 264

8y = 48

y = 6

x + 6 = 9

x = 3

Add a restaurant the ratio of kids meals sold two adult meals sold was 5:4 if there were 20 kids meals sold what is the combined amount of kids and adult meals sold?

Answers

Answer: The combined amount of kids and adult meals sold = 36

Step-by-step explanation:

Let the number of kids meals sold = 5x and the number of adult meals = 4x

Since total kids meals sold = 20

Then, 5x= 20

⇒ x =4

Adult meals = 4(4) = 16

Combined meals sold  =  kids meals + Adult meals

= 20+ 16

= 36

Hence, the combined amount of kids and adult meals sold = 36

Solve the equation-7(x-2)= -84

Answers

Answer:

x = 14

Step-by-step explanation:

First, use the distributive property:

-7x + 14 = -84

-7x = -98

x = 14

Answer:

my answer got deleted for no reason so ill add it again with my way of solving it with steps this time.

x=14

Step-by-step explanation:

divide both sides by -7

[tex]\frac{-7(x-2)}{-7} =\frac{-84}{-7}[/tex]

simplify

[tex]x-2=12[/tex]

add two to both sides

[tex]x-2=12[/tex]

    [tex]+2[/tex]   [tex]+2[/tex]

simplify

[tex]x=14[/tex]

hope having another method helps :)

If a triangle has three sides with the lengths 20, 16, and 12, what are the angles?

Answers

Answer:

angle a = 53.13°

angle b = 36.87°

angle c = 90°

Step-by-step explanation:

The following is one way to perform the calculation. It may not be the best way.

Calculates ∠A, ∠B, ∠C based on given a, b and c.

∠A = arccos(  b2 + c2 - a2 2bc )

= 0.9273 rad = 53.13° = 53.13°

∠B = arccos(a2 + c2 - b2 2ac )

= 0.6435 rad = 36.87° = 36.87°

∠C = arccos(a2 + b2 - c2 2ab )

= 1.5708 rad = π/2 = 90°
