Answer:

60 pages

Step-by-step explanation:

0.15x + 51 = x

51 = x - 0.15x

51 = 0.85x

51/0.85 = x

X = 60 (0.15 * 60 = 9 pages covered with pictures)

Answer:

20

Step-by-step explanation:

If a=3, b=7,

4a-5+3a-b-3+2b

= 4(3)-5+3(3)-7-3+2(7)

= 12-5+9-7-3+14

= 20

Answer:

1. Simplified: 7a + b - 8

2. Evaluated: 20

Step-by-step explanation:

4a - 5 + 3a - b - 3 + 2b =

4a + 3a - b + 2b - 5 - 3 =

7a + b - 8

7a + b - 8 = 7 * 3 + 7 - 8 = 21 + 7 - 8 = 20

Step-by-step explanation:

f(x) = ³√(x - 3)

f(-61) = ³√(-61 - 3)

f(-61) = ³√-64

f(-61) = -4

f(128) = ³√(128 - 3)

f(128) = ³√125

f(128) = 5

Answer:

It is 7x+21 and 7x+1 x 21

Step-by-step explanation:

The distributive property is 7x+21 and the cumulative property is 7x+1 x 21.

Given that multiplication is commutative, the distributive property can be used independently of the elements' relative positions. The Distributive Characteristics If a, b, and c are any real numbers:

Distribution favours multiplication over addition: Ab + Ac = a(b + c). A(b - c) = ab - ac shows how multiplication distributes across subtraction.

Given that Jeremy applied the distributive property to the expression 7(x+3)

Distributive property expression,

7 (x+3) = 7x + 21

Cumulative property expression,

7x + 21 = 7x + ( 7 x 3 )

Therefore, the distributive property is 7x+21 and the cumulative property is 7x+1 x 21.

112 cakes

Step-by-step explanation:

7×7=49

9×7=63

49+63=112

[tex]\text{Hello there!}[/tex]

First, we will need to find out how much each of the bakeries accrued within 7 days. We should be able to do this by simply multiplying the amount of cakes the bakery sells each day by the amount of days it's been accruing it for.

For example:

[tex]\text{7}[/tex] • [tex]\text{7}[/tex] = [tex]\text{49}[/tex]

[tex]\text{9}[/tex] • [tex]\text{7}[/tex] = [tex]\text{63}[/tex]

Since the answer doesn't explain if you're giving EACH of the bakeries amounts or combining them, that's up to you to decide if you want to do that or not.

The number of times we would spin a number divisible by 3 is 12.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Number of spins= 40

Now,

To predict how many times you would spin a number divisible by 3 in 40 spins, you can multiply the probability of spinning such a number by the number of spins. The probability of spinning a number divisible by 3 is 3/10, as there are 3 numbers out of 10 that are divisible by 3 (3, 6, and 9). the prediction is:

(3/10) x 40 = 120/10 = 12

You would expect to spin a number divisible by 3 about 12 times in 40 spins.

Therefore, by the given data the probability will be 12.

Answer:

f(h(-1)) = -2.5

Step-by-step explanation:

We are given:

f(x) = (x - 3)/4

h(x) = 3x - 4

Knowing this, first find h(-1).

h(-1) = 3(-1) - 4

Multiply 3 and -1.

h(-1) = -3 - 4

Subtract 4 from -3.

h(-1) = -7

Now knowing this evaluate the function out.

f(h(-1)) = f(-7)

Evaluate f(-7).

f(x) = (x - 3)/4

Substitute variable.

f(-7) = ((-7) - 3)/4

Subtract 3 from -7.

f(-7) = (-10)/4

Divide -10 by 4.

f(-7) = -2.5

This means that f(h(-1)) = -2.5.

Factoring: 25x2 - 4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A² - AB + BA - B² =

A² - AB + AB - B² =

A² - B²

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 25 is the square of 5

Check : 4 is the square of 2

Check : x2 is the square of x1

Factorization is : (5x + 2) • (5x - 2)

Multiplying Exponential Expressions:

4.1 Multiply (x + 3) by (x + 3)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is (x+3) and the exponents are :

1 , as (x+3) is the same number as (x+3)1

and 1 , as (x+3) is the same number as (x+3)1

The product is therefore, (x+3)¹ = (x+3)²
