Answer:
a) 7x words
b) 1000/x days
c) 15000 + 10x words
Step-by-step explanation:
The best way to do this would be to plug in real numbers to see how each situation would play out. For example, for part a, let's say he learns 20 new words each day. One week has seven days, so that would be 20 x 7, which is 140 words. You multiply the # of days by the # of words, which is x.
For part b, if he tried to reach 1000 new words by doing 20 new words a day, you would find how long that would take by doing 1000 / 20, which would give you 500 days. You divide the # of new words he's trying to reach by the # of words a day.
For part c, he already has a set # of new words that he's learned, and now he's just continuing the progress, so you start out with 15000, then add that to 10 new words a day multiplied by # of days (x).

Which of the following values are solutions to the inequality —8 – 4x > 1?
1. -10
2.-1
3. 6
Answers
Answer:
option 1. -10
Step-by-step explanation:
—8 – 4x > 1
adding 8 on both sides,we get
-8-4x+8>1+8
-4x>9
by dividing both sides by -4, we get
-4x/-4<9/-4
x<-2.25
Hence, from the above option only -10 is smaller than -2.25. Therefore your answer is option 1.

The area of a square is 16cm²
What is the perimeter?
Answers
Answer:
Perimeter = 16 cm
Step-by-step explanation:
The formula for a square's area = s^2 where the length of the side is s.
s^2 = 16 Take the square root of both sides
sqrt(s^2) = sqrt(16)
s = 4
The perimeter is the same
P = 4*s
P = 4 * 4
P = 16
Answer:
16
Step-by-step explanation:
Square root of 16 = 4cm
4 sides, 4 * 4 = 16cm

there are 14 math teachers and 26 science at school today what is the ratio of math teachers and science at school?
Answers
Answer:
Answer is 7:20
It's basically asking "what is the ratio of math teachers to total teachers?" assuming there are only math and science teachers at this school. For the sake of simplicity, let's just go with that. We have 14 math teachers and 14+26 = 40 teachers total. The ratio of math to total is 14:40 which reduces to 7:20 when we divide both parts of the ratio by the GCF 2.
Step-by-step explanation:
Answer:
the ratio is
14:26
but you can leave the answer like this the two numbers can be divided by 2 so
14/2=7 and 26/2=13
then the answer is 7:13.

35+ x + 60 = 180
95 + x = 180
x = 180 – 95
x = 85
So; X = 85° ; < PON(iV)
x + 47 + 75 = 180
x + 122 = 180
x = 180 – 120
x = 58
So; x = 58° ; < COB(Vi)105 ° = 3 x° –> Opposite angles ,
x = 105 / 3

using the variable n write an algebraic expression for a number increased by 6
Answers
The answer you are looking for is simply just n+6.
Solution/Explanation:
If you use the variable "n" to write an algebraic expression, for a number increased by 6, you must write it like this:
n+6.
And, also, increase obviously means the same thing as adding.
So, therefore, "n" stands for the number in this algebraic expression, and if you add 6 to that number "n," it must be n+6.
So, therefore, the final answer is n+6.

Hey there! I'm happy to help!
When evaluating the value of an expression, we need to follow the order of operations which is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction).
First, we will evaluate the exponent. 3² is 3×3 which is 9.
[tex]\frac{9+2*8}{16-11}[/tex]
Now we have to do multiplication. Since the multiplication sign is between the 2 and the 8, that is what we multiply.
[tex]\frac{9+16}{16-11}[/tex]
Then we will do our addition and subtraction.
[tex]\frac{25}{5}[/tex]
Since all fractions are just division problems, we can do 25÷5.
25÷5=5
So, the value of this expression is 5.
