8=f-(13-2)
???? help

Answers

Answer 1

Answer:

I got you

Step-by-step explanation:

f= 19

Answer 2
Simplifying
8 = F + -1(13 + -2)

Combine like terms: 13 + -2 = 11
8 = F + -1(11)

Multiply -1 * 11
8 = F + -11

Reorder the terms:
8 = -11 + F

Solving
8 = -11 + F

Solving for variable 'F'.

Move all terms containing F to the left, all other terms to the right.

Add '-1F' to each side of the equation.
8 + -1F = -11 + F + -1F

Combine like terms: F + -1F = 0
8 + -1F = -11 + 0
8 + -1F = -11

Add '-8' to each side of the equation.
8 + -8 + -1F = -11 + -8

Combine like terms: 8 + -8 = 0
0 + -1F = -11 + -8
-1F = -11 + -8

Combine like terms: -11 + -8 = -19
-1F = -19

Divide each side by '-1'.
F = 19

Simplifying
F = 19

5(a + 3b) = 5a + 15b

Also is it a Commutative or associative or distributive ??

Answers

Answer: This is distributive property.

Good Luck

A=1 B=1
This is because it is the same problem on each side so 5a divided by 5 is A or 1 and same for 15b

PLEASE MAKE SURE HELP ME!

Answers

Answer:

1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)

2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal

3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.

the quotient of a number x and 3 is at most 4
an inequality is ?
the solution is ?

Answers

Answer:  The inequality is   x/3 [tex]\leq[/tex] 4   and   x [tex]\leq[/tex] 12

Step-by-step explanation:

The quotient of x and 3 is the same as x/3  and the at most sign is less than or  equal to. x/3 has to be  less than or equal to  4 which can be represented by the inequality,

x /3 ≤ 4            Solve for x by multiplying both sides by 3.

x ≤ 12

A block of clay contains twenty 4 - ounce portions of clay. Ceramics teacher wants to use the block to make as many spheres of clay as possible. Each weighing ⅖ pound. How Many spheres can the class make

Answers

Answer:

12.5

Step-by-step explanation:

20 x 4 = 80

80 ÷ 16 = 5

5 ÷ 2/5 = 12.5

Using 24 ounce portions of clay, maximum they can make 3 spheres.

Given that, a block of clay contains 24 ounce portions of clay.

What is metric conversion?

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

We know that, 1 pound = 16 ounces

So, 1 ounce = 1/16 pound

Then 24 ounce = 24/16

= 1.5 pound

Here, each sphere of clay weighing 2/5 = 0.4 pounds

Number of spheres = 1.5/0.4

= 3.75

Maximum 3 spheres

Therefore, using 24 ounce portions of clay, maximum they can make 3 spheres.
