Answer:
x = -17
y = -68
Step-by-step explanation:
x - y = 51
y/x = 4 so we can say that y = 4x
using substitution:
x - 4x = 51
-3x = 51
x = -17
find 'y':
-17 - y = 51
-y = 68
y = -68
check:
-17 - (-68) = 51
51 = 51
-68/-17 = 4
4 = 4

Is the ratio 15 : 12 equivalent to 5 : 3 and 10 : 6? Explain.
Answer:
Yes it is
Step-by-step explanation:
When we simplify 15:12, we receive 5:3
Therefore, 5:3 is equvilaent to 15:12
Using this unit ratio, we can solve for other rations
For example, 5:3, the unit ratio, times 2 is 10:6
5 * 2 = 10
3*2 = 6
10, 6 = 10:6

Answer:
100% is an integer multiple of 10%
Step-by-step explanation:
100% is not an integer multiple of 30%, so it is difficult to use 30% directly to determine the value of 100%. Dividing 30% by 3 to get 10% then gives you a value that can be multiplied by 10 to find 100%.

over the past ten years, the towns population doubled in size. the population is currently 12,000. what was the population ten years ago?
which of the following represents the given word problem if “P” represents the population ten years ago?
1. P=2(12,000)
2. 2P=12,000
3. 2(P+10)=12,000
Answer:
If P represents the population ten years ago, the current population can be expressed as: 2P = 12,000 (or: 2 x 6,000 = 12,000). Over the past ten years, the town's population doubled in size. The population is currently 12,000. Therefore the population ten years ago was 12,000 divided by 2 = 6000.

Linear functions change at a constant rate per unit interval. An exponential function changes by a common ratio over equal intervals.
A number is equal to 3 times a smaller number. Also, the sum of the smaller number and 4 is the larger number. The
situation is graphed on the coordinate plane below, where x represents the smaller number and y represents the
larger number
Answer:
The answer is that in my case y (the smaller number) is 2 and x (the bigger number) is 6
Step-by-step explanation:
The equations are x=3*y and y+4=x. This makes y=2 and x=6.

The side length of an equilateral triangle is 6 cm. What is the height of the triangle?
I’m super confused !!
9514 1404 393
Answer:
(c) 3√3
Step-by-step explanation:
The altitude forms the long side of a 30°-60°-90° right triangle whose short side is 6/2 = 3 cm.
The ratios of side lengths in a 30°-60°-90° triangle are ...
1 : √3 : 2
Multiplying these ratio values by 3 gives the right triangle side lengths of ...
3 : 3√3 : 6
where 6 is the side length of the equilateral triangle. The length 3√3 is the altitude of that equilateral triangle.
The height of the triangle is 3√3 cm.
Marina has a bag of lemon watermelon and strawberry candies she is going to choose one candy from the bag the probability of choosing strawberry candy is 1/5 there are 16 lemon candies and eight watermelon candies in the bag how many strawberry candies are in the bag
Answer:
There are 6 strawberry candies in the bag
Step-by-step explanation:
The probability of an event occurring = (The number of required outcome) ÷ (The number of possible outcome)
The given parameters in the question are;
The number of different types of fruit in Marina's bag = 3
The type of fruits in the bag = Lemon, watermelon, strawberry
The probability of choosing strawberry, P = 1/5
The number of lemon candies in the bag = 16
The number of watermelon candies in the bag = 8
Let, 'x', represent the number of strawberry candies in the bag
Therefore, by the definition of probability, we have;
P = 1/5 = x/(x + 16 + 8)
x + 16 + 8 = 5·x
16 + 8 = 5·x - x = 4·x
24 = 4·x
∴ x = 24/4 = 6
The number of strawberry candies in the bag, x = 6 strawberry candies.

5.26 is less than 5.4
Answer:
5.26 < 5.4
Step-by-step explanation:
I hope it's okay that I didn't use the number line.
Try rounding the numbers. 5.26 would round to 5.3, which is less than 5.4. Therefore, the answer is 5.26 < 5.4.

Two of the angles in a triangle measure 21° and 40°. What is the measure of the third angle
Answer: 119°
Step-by-step explanation:
The total of the interior angles of a triangle is 180° so if you add the two angles you have, you get 61 and just subtract that from 180 to get the missing angle.

Which expression could you simplify by multiplying exponents?
Anyone know this?? Question: find the area of the shape. Don’t forget your units and use 3.14 if you need to use pi.
Area of this shape = 614²
Answer with steps :Length of side of the first square = 10
It's area :
[tex] =\tt side \times side[/tex]
[tex] = \tt10 \times 10[/tex]
[tex] = \tt {100}^{2} [/tex]
Thus, the area of the first square = 100²
Length of the side of the second square = 10
It's area :
[tex] = \tt \: side\times side[/tex]
[tex] =\tt 10 \times 10[/tex]
[tex] = \tt{100}^{2} [/tex]
Thus, the area of the second square = 100²
Length of the side of the third square = 10
It's area :
[tex] =\tt side \times side[/tex]
[tex] = \tt 10 \times 10[/tex]
[tex] = \tt {100}^{2} [/tex]
Thus, the area of the third square = 100²
(pi value = 3.14)
Radius of the first semicircle = 10 cm
It's area :
[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]
[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]
[tex] = \tt\frac{3.14 \times 100}{2} [/tex]
[tex] =\tt \frac{314}{2} [/tex]
[tex] =\tt {157}^{2} [/tex]
Thus, the area of the first semicircle = 157²
Area of the second semi circle :
= area of the first semicircle
= 157²
Thus, the area of the second semicircle = 157²
Total area of the figure :
= Area of the 3 squares + Area of the two semi circles
[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]
[tex] = \tt300 + 314[/tex]
[tex] = \tt {614}^{2} [/tex]
Therefore, the total area of the figure = 614²
On a coordinate grid, point R is at (−6, 2) and point S is at (8, 2). The distance (in units) between points R and S is ______. (Input only whole numbers, such as 2.)
Answer:
Step-by-step explanation:
Difference of x-coordinates = -6-8 = -14
Difference of y-coordinates = 2-2 = 0
Distance = √((-14)^2+0^2) = 14
