Answer:
The larger is 22, the smaller is 9.
Step-by-step explanation:
We need to make the two equations for this which would be:
x+y=31
x=2y+4
we can put the second equation into the first
(2y+4)+y=31
3y+4=31
subtract 4 from each side
3y=27
divide each side by 3
y=9
put this y into our second equation
x=2(9)+4
x=18+4
x=22

The total length of a beach is 13.2 kilometers. If lifeguards are stationed every 0.6 kilometers, including one at the end of the beach, how many lifeguards will there be on the beach?
Answer:
22 including one at the end of the beach
Step-by-step explanation:
Total length of the beach = 13.2 kilometers
If lifeguards are stationed every 0.6 kilometers, INCLUDING one at the end of the beach
Number of lifeguards in the beach = Total length of the beach / distance interval of each lifeguards
= 13.2 kilometers / 0.6 kilometers
= 22
Number of lifeguards in the beach = 22 including one at the end of the beach

A six-sided die is tossed and a coin is flipped. What is the fractional probability that the die lands on an even number and the coin is heads?
Answer:
the die: 1/2, coin: 1/2
Step-by-step explanation:
There are 6 sides on a die and 6 numbers, 3 are even numbers which means 3/6. simplify it to get 1/2
there are 2 sides on a coin, one is heads. Therefore, the probability is 1/2
The fractional probability that the die lands on an even number and the coin is heads is [tex]\frac{1}{4}[/tex].
What is probability?"Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty."
Given, a die is tossed and a coin is flipped.
Therefore, the number of outcomes in case of die is 6 and the number of favorable outcomes is 3.
Hence, in case of the die, probability of getting an even number is P(A) = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex].
Again, the number of outcomes in case of the coin is 2 and the number of favorable outcomes is 1.
Hence, in case of the coin, probability of getting head is P(B) = [tex]\frac{1}{2}[/tex].
Now, the fractional probability that the die lands on an even number and the coin is heads is = P(A) × P(B) = [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex].

IF its a pretest the grade doesnt count im pretty sure.
Answer:
1. 15% of 48= 7.2
2. 25% of 80= 20
3. 135% of 70= 94.5
4. 7/10 of 100= 0.7
5. Solution for 36 is what percent of 50:
36: 50*100 =
(36*100): 50 =
3600: 50 = 72
6. Solution for 4 is what percent of 20:
4: 20*100 =
(4*100): 20 =
400: 20 = 20
7 30 is 50% of what number
50% is half of 100 so all you do is times the number by 2 which is 30 to get 60
8. 2 is 25 percent of what number?
again 25% you need to do 4 times 25 to get 100 so you do 12 x 4 and you get 48
9 its 800 so 75 again is 3 x 25 so you divide 600 by 3 and you get 200 so then to get 100 percent you do 4 x 200 and you get 800 so the awnser is 800

10x + 4y = 20
13x - 4y = -66
If x = -2, what is the value of y?
Answer:
y = 10
Step-by-step explanation:
If x = -2
10x + 4y = 20
10(-2) + 4y=20
-20+4y=20
4y= 20+20
4y=40
y=10
If x=2 and y=10
13x - 4y = -66
13(-2) - 4(10) =-66
-26 -(-40) = 66 so it all checks out!!
please can someone express √5 as a fraction?
SInce this continued fraction does not terminate, we can tell that √5 cannot be represented as a terminating fraction - i.e. a rational number. So √5 is an irrational number a little smaller than 214=94 . For better rational approximations you can terminate the continued fraction after more terms.
hope this help!

What is the product of -8/9 x -6/7
Answer:
16/21
Step-by-step explanation:
In the first fraction, the negative numerator and negative denominator cancel each other.
In the second fraction, the negative numerator and negative denominator cancel each other.
The equivalent equation is
8/9×6/7=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
8×6/9×7=48/63
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 48 and 63 using
GCF(48,63) = 3
4/8÷43/63÷3=16/21
Therefore:
−8/9× −6/7=16/21

What is the measure of angle x?
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Angles.
Applying, angle sum Property of a triangle and linear pair, we get as,
180°-107 = 73°
, now angle sum property,
=> 31+73+p = 180
=> p = 180-104
=> p = 76°
here, angle p = angle x, they are vertically opposite angles, hence,
x = 76°
hence
which is perpendicular to the line y=-3x-8y
Answer:
I believe the answer is y = -7/3x
Step-by-step explanation:
When you rearrange the equation, y = -3x - 8y, you will get -7y = -3x.
We want the equation to be equal to y by itself. So we divide -7 from both sides, giving us the equation y = 3/7x.
The graph that is perpendicular to y = 3/7x is it's reciprocal: y = -7/3x
Answer:
3
Step-by-step explanation:
Find the Slope of a Perpendicular Line
y = −3x − 8y
Rewrite in slope-intercept form.
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Move all terms containing y to the left side of the equation.
9y = −3x
Divide each term by 9 and simplify.
y = −(x/3)
Write in y = mx + b form.
y = -(1/3)x
Using the slope-intercept form, the slope is − (1/3)
m = -(1/3)
The equation of a perpendicular line to y = − (1/3)x must have a slope that is the negative reciprocal of the original slope.
[tex]m[/tex]perpendicular = [tex]-\frac{1}{-\frac{1}{3} }[/tex]
Simplify the result.
[tex]m[/tex]perpendicular = 3
