Answer:
7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each
Step-by-step explanation:
5x + 8y = 139
x + y = 20
x = 20 - y
5x + 8y = 139
5(20 - y) + 8y = 139
100 - 5y + 8y = 139
100 + 3y = 139
3y = 139 - 100
3y = 39
3y/3 = 39/3
y = 13
x + y = 20
x + 13 = 20
x = 20 - 13
x = 7
Find the equation of the line, whose slope is 5 and x- intercept is 2
Answer:
Step-by-step explanation:
when x intercept is points given, then y = 0
So far, you have y = 5x + b where b = the yintercept
x = 2
y = 0
0 = 5x + b
0 =5 * 2 + b
0 = 10 + b Subtract 10 from both sides.
-10 = b
Equation: y = 5x - 10
if the original quantity is 8 and the new quantity is 4 what is the percent decrease
Answer:
50% decrease
Step-by-step explanation:
it would be a 50% decrease because half of 8 is 4 and 1/2 is 50 %.
8. Evaluate: f(x) = x2 + 1
g(x) = 5 - x
a. (f+g)(x) =
b. (f-g)(x) =
Answer:
(f+g)(x)=2x+1+5 - x
(f+g)(x)=x + 6
(f - g)(x)= 2x + 1 - (5- x )
(f - g)(x)= 3x - 4

Factorise -x^2-20x-100
Answer:
(x+10)(x+10) or (x+10)^2
Step-by-step explanation:
Divide by -1 first
a=1
b=20
c=100
Since a*c whose sum is b...
1*100=100
10*10=100 and adds to 20
The answer is (x+10)(x+10) or (x+10)^2

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
Write the slope-intercept form of the equation of the line through the given point.

Start with a unlock code of 100. For each of the following statements that is true, add 10 TIMES its statement number to the unlock code. Enter your final number to unlock the door
1. 1/2 + 3/4=3/4
2. 5/8 - 1/4 = 3/8
3. 4/5 + 7/10 = 1 1/2
4. 2 1/2 - 1 5/6 =1/6
1/2 + 3/4 = 3/4 ........... false, so we do not add anything
5/8 - 1/4 = 3/8 ............ true, so we have (10 * 3/8) = 15/4
4/5 + 7/10 = 1 1/2 ....... true, so we have (10 * 1 1/2) = 15
2 1/2 - 1 5/6 = 1/6 ...... false, so we do not add anything.
we are then left with 15/4 and 15, on adding all together, we have
100 + 15/4 + 15 = 118.75

The dimensions of a right triangle are shown in the diagram.
What is the length of the missing side, to the nearest tenth of a centimeter?
Answer:
18.4 cm
Step-by-step explanation:
For this problem, you would use Pythagorean Theorem or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. Picture the 90 degree angle as an arrow pointing to the hypotenuse. In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!
a bag contains 300 balls. 96 balls are yellow. Which answer shows both the correct proportion and the correct percent of yellow balls in the bag.
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %
What is Percentage and Proportion?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The number of balls in the bag = 300
The number of yellow balls in the bag = 96
The proportion of yellow balls =
The number of yellow balls in the bag / The number of balls in the bag
The proportion of yellow balls = 96 / 300
= 24 / 75
= 8 / 25
Therefore , The proportion of yellow balls in the bag is 8 / 25
Now ,
The percentage of yellow balls in the bag =
Number of yellow balls in the bag / Number of balls in the bag x 100 %
The percentage of yellow balls in the bag = ( 8 / 25 ) x 100 %
= 8 x 4 %
= 32 %
Hence ,
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %
