Answer:

Thabo had 51 crayons at the start.

Step-by-step explanation:

Sam has three times as many crayons as Thabo. Then

x = 3y.

If Sam gives 17 crayons to Thabo, then he will have twice as many crayons as Thabo. Then

(x-17) = 2(y+17).

Thabo had 51 crayons to start with.

Given that Sam has three times more crayons than Thabo does. He will have twice as many crayons as Thabo if he gives him 17 of them.

We need to determine the number of crayons Thabo had in starting.

Let's use algebra to solve this problem step-by-step.

Let's assume that Thabo starts with "x" crayons.

According to the given information:

Sam has three times as many crayons as Thabo, which means Sam has 3x crayons.

If Sam gives Thabo 17 crayons, he will have (3x - 17) crayons left.

Thabo will have (x + 17) crayons after receiving the 17 crayons from Sam.

Now, the second condition states that if Sam gives Thabo 17 crayons, he will have twice as many crayons as Thabo.

Mathematically, it can be expressed as:

2(x + 17) = 3x - 17

Let's solve this equation to find the value of x:

2x + 34 = 3x - 17

Subtract 2x from both sides:

34 = x - 17

Now, add 17 to both sides:

x = 51

So, Thabo had 51 crayons to start with.

Step-by-step explanation:

hope it helps :)

The required factor for the given expression is (x + 4)(3x - 1).

In mathematics, factorization or factoring refers to the process of composing a number or other mathematical object from numerous factors, usually smaller or simpler counterparts.

The given expression is 3x² + 11x - 4.

To factor a general quadratic expression of the form ax² + bx +c, we need to consider the product "ac" and find two factors for this number such that their sum is equal to b. during this case, a = 3, b = 11, and c = -4..

Therefore we need to consider the product ac = 3 × (-4) = -12.

Consider the 2 factors 12 and -1 for the product -12.

Then we have the sum is equal to 12 + (-1) = 12 - 1 = 11.

Therefore the expression 3x² + 11x - 4= 3x² + 12x + (-1)x -4= 3x² +12x - x - 4= 3x(x + 4) - (x + 4)= (x + 4)(3x - 1)

Therefore, the required factor for the given expression is (x + 4)(3x - 1).

Answer: x = 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

Given equation,

→ 5(2x + 1) = 25

Solving for the value of x,

→ 5(2x + 1) = 25

→ 10x + 5 = 25

→ 10x = 25 - 5

→ x = 20/10

→ [ x = 2 ]

Hence, the value of x is 2.

Step-by-step explanation:

The correct unit price is $1.24 per pair of padded gloves such that the contractor's unit price is incorrect because total cost was divided by number of dozens bought instead of the number of units in 6 dozens

How many units are in a dozen?

The dozen of pairs of padded  gloves contains 6 pairs of padded  gloves, in other words, the number of units in 6 dozens is 6 dozens multiplied by 12 units in a dozen

number of units in 6 dozens=6*12

number of units in 6 dozens=72

unit price=total cost/number of units in 6 dozens

unit price=$89.28/72

A number that can be expressed in scientific notation will be (2 × 10³) × 4 × 10².

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation. It may also be referred to as standard form, scientific form, or standard index form.

Always set the base to 10. The exponent must be an integer that is non-zero, therefore it can either be positive or negative. The coefficient's absolute value is more than or equal to 1, but it must be less than 10.

It should be noted that the number that can be expressed in scientific notation will be (2 × 10³) × 4 × 10². This will be:

Answer: m<8=97 degrees.

m<5=83 degrees

Step-by-step explanation:

m<8=m<2 ==> Angles 8 and 2 are alternate interior angles, meaning that they're equal.

m<8=97 degrees.

m<8+m<5=180 degrees ==> Both angles 8 and 5 add up to a straight line, and straight lines measure 180 degrees and are called straight angles.

97+m<5=180

97-97+m<5=180-97

m<5=83 degrees

Answer:

Step-by-step explanation:

As we know that a-b=7 and ab=8(a times b is equal to 8) If we find the factors of 8 we know that 8 times 1 make 8 and if u try 8-1= 7 so 1 squared is 1 and 8 squared is 16 so 16+1=17

Answer:

A = 8

B = 1

A squared + B squared = 65

Step-by-step explanation:

8 - 1 = 7

A - B = 7

8 x 1 = 8

A x B = 8

8 x 8 = 64

1  x 1 = 1

64 + 1 = 65

A squared + B squared = 65

Since the ratio is 12 : 5, the statement which is true is there are more than twice as many cows as there are sheep.

The ratio between the number of cows to number of sheep in a field is given as:

12 : 5

Now,

let the number of sheep be 5 x.

So, the number of cows will be 12 x.

So, we get that:

12 x > 2 ( 5 x)

12 x > 10 x

So, the statement which is true will be:

there are more than twice as many cows as there are sheep
