2. The hamster, x, walked 20 feet. The guinea pig walked 1/4 less than that. The guinea
pig walked
feet
You question is a little unclear but I'm going to assume you meant how much the guinea pig walked.
The hamster walked 20 feet, and the guinea pig walked 1/4 less. So you find 1/4 of 20, which is 5. Then, you subtract 20 and 5: 20-5 = 15. So the guinea pig walked 15 feet.
Determine the given equation is a linear equation write yes or no. If yes, write the equation in standard form.
7n - 8m = 4 - 2m.
Use Standard form
Answer:
The equation is linear. Standard form:
7n - 6m - 4 =0
Step-by-step explanation:
Linear Equations
The linear equations are identified because all terms form a polynomial of degree 1 or zero (no variable).
The standard form of a linear equation is:
ax+by+cz+d=0
where x, y, z are the variables, and a,b,c are constants.
The equation:
7n - 8m = 4 - 2m
Is linear, both variables have an exponent of 1 and there is an independent term. Moving all terms to the left side:
7n - 8m - 4 + 2m =0
Simplifying:
7n - 6m - 4 =0

sin^2x + sin^2x + cos²x
Answer:
Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.

Answer:
3x + 2 = 14
3x + 2 - 2 = 14 - 2
3x = 12
3x/3 = 12/3
x = 4
Step-by-step explanation:
3x + 2 = 14
subtract 2 from both sides
3x + 2 - 2 = 14 - 2
combine like terms.
3x = 12
divide both sides by 3
3x/3 = 12/3
x = 4

If u place a 13 foot ladder against a 12 foot building,how many feet will the Ladder be from the building
Answer:
5 feet
Step-by-step explanation:
When you place the 13 foot ladder, the ladder, floor, and wall forms a right triangle and the ladder will become the hypotenuse.
We use the Pythagorean Theorem. Let x be the distance from the building.
x^2 +12^2 = 13^2
x^2 + 144 = 169
x^2 = 169 - 144
x^2 = 25
Take the square root of 25 and you get 5
x = 5
Which equation is true when the value of x is -12
Answer:
Which equation is true when the value of x is -12 HERE YOU GO!!
Step-by-step explanation:
tricky ... let's see ...
I notice that if we subtract xy from both sides we get
7x + xy - xy = xy - xy + 21
then
7x = 21
and
x = 21/7 = 3
so there is only one value of x that satisfies the equation
x = 3
Going back to the original equation we see that any value of y will satisfy the original equation
we can see this by rearranging things:
7x + xy - xy = 21
here, I have performed the subtraction of xy on the right side as above, but have left the left side undone
(so we don't lose the presence of y)
Note that the above can also be written as
7x + (x - x)y = 21
or
7x + 0y =21
now, since anything times zero equals zero,
y may be any number.
Let's summarize:
1) x = 3
2) y = anything
looking back at the original question;
1) the equation is true for all ordered pairs
FALSE (only one x works, not all x)
2) there are no x and y pairs for which the equation is true.
FALSE (x=3, y=anything) makes it true, i.e. (3,1)
3) For each value of x, there is one and only one value of y that makes the equation true,
FALSE for each value of x, for the one value of x, x=3, y can be any number, which is an infinite number, not one
4) for each value of y, there is one and only on value of x that makes the equation true.
TRUE!! for all the infinite values of y you may pick, there is one and only one x you may pick, x = 3

Help!!! Explain too please
Answer:
5 cm/s
Step-by-step explanation:
The rate of change (ROC) is the speed at which the y variable (hieght) increases with the x variable (time). so ROC = 5.
the linear equation is y = mx + b, m is also the roc, b is the initial value, so,
if y = 60, x = 4 & b = 40, then making m the subject of equation will give the value of the ROC. i.e m = (y - b)/x = (60 - 40)/4.
What does the slope represent in this scenario?
Answer:
Then change in time divide by the change in Temperature

One city has a population of about 2,840,000 people. Another city has
about 3,120,000 people. About how many people live in both cities?
Answer:
5,960,000
Step-by-step explanation:
Population in one city= 2,840,000
Population in another city= 3,120,000
Population living in both cities= 2,840,000 + 3,120,000 = 5,960,000
is 8/4 equivalent to 10/5?
These are just some equivalent fractions of 8/4:
2/1 = 4/2 = 6/3 = 8/4
= 10/5 = 12/6 = 14/7 = 16/8
= 18/9 = 20/10 = 22/11 = 24/12
= 26/13 = 28/14 = 30/15 = 32/16
= 34/17 = 36/18 = 38/19 = 40/20
= 42/21 = 44/22 = 46/23 = 48/24
= 50/25 = 52/26 = 54/27 = 56/28
= 58/29 = 60/30 = 62/31 = 64/32
= 66/33 = 68/34 = 70/35 = 72/36
= 74/37 = 76/38 = 78/39 = 80/40
= 82/41 = 84/42 = 86/43 = 88/44
= 90/45 = 92/46 = 94/47 = 96/48
= 98/49 = 100/50 = 102/51 = 104/52
= 106/53 = 108/54 = 110/55 = 112/56
= 114/57 = 116/58 = 118/59 = 120/60
= 122/61 = 124/62 = 126/63 = 128/64
= 130/65 = 132/66 = 134/67 = 136/68
= 138/69 = 140/70 = 142/71 = 144/72
= 146/73 = 148/74 = 150/75 = 152/76
= 154/77 = 156/78 = 158/79 = 160/80
= 162/81 = 164/82 = 166/83 = 168/84
= 170/85 = 172/86 = 174/87 = 176/88
= 178/89 = 180/90 = 182/91 = 184/92
= 186/93 = 188/94 = 190/95 = 192/96
= 194/97 = 196/98 = 198/99 = 200/100

Answer:
[tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex]
Step-by-step explanation:
The formula is actually d= [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]. Now first, we have to find points A and C.
Point A is (1,2) and Point C is (-1,0).
Now we have to substitute the values in. That would make it d =[tex]\sqrt{(-1-1)^{2} + (0-2)^{2}}[/tex].
To simplify the parentheses, it would get to d= [tex]\sqrt{(-2)^{2}+(-2)^{2} }[/tex].
To simplify the exponents, it would get to d = [tex]\sqrt{4+4}[/tex].
To simplify the square root, it would get to d = [tex]\sqrt{8}[/tex].
So the answer is either [tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex].

Match the following definitions with their word
Answer:
A: law
B: The opposite of a number is its additive inverse. The sum of a number and its opposite is zero. (This is sometimes called the property of opposites ).
C: To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

A box contains 6 blue pens and 10 red pens. What is the ratio of red pens to total pens as a fraction
Answer: 5/8
Step-by-step explanation: The ratio is 10:16 because total of 16 pens and 10 being red.
The ratio of red pens to total pens as a fraction is 5/8.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
The ratio of red pens to total pens can be expressed as a fraction. To find this fraction, we need to divide the number of red pens by the total number of pens.
The total number of pens in the box is 6 blue pens + 10 red pens = 16 pens
So, the fraction representing the ratio of red pens to total pens is:
10/16
It can be simplified by dividing both the numerator and denominator by 2, to get
5/8
So the ratio of red pens to total pens as a fraction is 5/8. This means that out of every 8 pens, 5 are red.
