Answer:
8
Step-by-step explanation:
[tex]slope = \frac{w - 2}{0 - ( - 1)} \\ \\ \therefore \: 6 = \frac{w - 2}{0 + 1} \\ \\ \therefore \: 6 = \frac{w - 2}{1} \\ \\ \therefore \:w - 2 = 6 \\ \\ \therefore \:w = 6 + 2 \\ \\ \therefore \:w = 8\\ \\ [/tex]
Factorize the following 3x + 12
Answer:
if this was a equation you would first subtract 12 from the other number then divide it by 3
Answer:
3(x+4)
Step-by-step explanation:
Check 3(x+4), when you use the distributive property, you get 3x + 12, so this is correct. (sorry, I'm really bad at explaining...)
8 out of every 14 children in a school are boys. What is the ratio of boys to girls in the school?
Answer:
8:6
Step-by-step explanation:
If 8 out of 14 students are boys then the remaining number of students must be girls
So
14-8= 6
There are 6 girls out of the 14
So as a ratio of boys to girls
8:6
Answer:
8 : 6 <or> 4 : 3
Step-by-step explanation:
8 : 6 <or> 4 : 3
Since there are 8 boys out of 14, if you minus them , the answer will be the number of girls out of 14.

The probability of spinning an odd number, flipping heads and then spinning a 3 is?
===================================================
Work Shown:
A = probability of landing on an odd number
A = 5/9 because there are 5 odd numbers out of 9 total
B = probability of getting heads
B = 1/2
C = landing on 3 on the spinner
C = 1/9
Multiply the values of A,B,C
A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162
Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%

What is a polynomial expression?Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11
Given here: The statement " Product of z and 7 added to 10"
Now the product of z and 7 is given by 7z
Now adding 10 to the monomial we get
7z+10
Thus the result is a binomial
Hence, The required expression is the binomial 7z+10

Si compraste 0.5mts de alambre grueso con un costo de 4.00 pesos por metro y 0.4 más de alambre delgado con un costo de 5.00 pesos por metro ¿cuanto fue el costo total en la compra de los metros de alambre
Answer:
El costo total es 4 $.
Step-by-step explanation:
Sabemos que el metro de alambre grueso cuesta 4 pesos y el metro de alambre delgado cuesta 5 pesos.
Entonces:
Costo de alambre grueso
[tex]0.5\: m*4\frac{\$}{m}=2\: $[/tex]
Costo de alambre delgado

If 7x - 4y = 23 and x + y = 8, what is the value of x?
Answer:
x=5
Step-by-step explanation:
7x - 4y = 23 and x + y = 8
Multiply the second equation by 4
4x + 4y = 32
Add this to the first equation
7x - 4y = 23
4x + 4y = 32

What is the weight of a science book if its mass is 250g
2.45 N
weight = mass x 9.8 m/s^2
Answer:
Here,
Mass ( m ) = 250g = (250/1000) kg =0.25 kg
g =9.8 m/s^2
Weight ( W ) = ?
We know that,
Weight ( W ) = m*g [Where g is acceleration due to gravity]
= (0.25*9.8) N
= 2.45 N

4(2.25w+3.1)-2.75w=44.9
Answer:
w = 5.2
Step-by-step explanation:
4(2.25w + 3.1) - 2.75w = 44.9
9w + 12.4 - 2.75w = 44.9
6.25w + 12.4 = 44.9
6.25w = 32.5
w = 5.2
4(2.25w+3.1)-2.75w=44.9
9w+12.4-2.75w=44.9
9w-2.75w+12.4=44.9
44.9-12.4=32.5
9w-2.75w=32.5
6.3w/6.3=32.5/6.3
=5 10/63
