Answer:
-9/4, -5/2, so on. As it is a proper/improper fraction it is good.
Step-by-step explanation:
please help, I'm so confused I got -2x -15x
Answer:
16x-3
Step-by-step explanation:
It is the same as:
-4x+2+20x-5
Add -4x and 20x:
-4x+20x=16x
2-5=-3
16x-3
(-4x + 2) + (20x - 5)
Expand the brackets.
-4x + 2 + 20x - 5
Add like terms.
16x - 3
The answer is a. I hope this helps! Let me know if I got anything wrong or if you need more help!

Answer:
7,21,27,81,87, 261, 267....
Step-by-step explanation:
All odd number series from the given figure is
7, 21, 27, 81 , 87....
We can write this series as
7, 7 x 3 , (7x3)+6, ((7x3)+6)x3, (((7x3)+6)x3)+6....
7, 21, 21+6 , 27 x 3, 81+6...
Now, the next term of the series will be
=((((7x3)+6)x3)+6) x 3
= 87 x 3
= 261
And another term of the series will be
= 261 +6
= 267
7,21,27,81,87, 261, 267....
Sarah has three more than four times the money that Jessica has. Together they have $72. How
much does each person have?
Answer:
Jessica has x amount of dollars.
Sarah has 4x + 3
Together they have $72
We can combine Jessica and Sara's money to equal $72.
x + (4x + 3) = 72
Combime like terms
5x + 3 = 72
Subtract 3 from both sides to isolate the variable.
5x = 69
Divide both sides by 5
x = 69/5 or 13 4/5 or 13.80
Jessica has $13.80 and
Sarah has 4(13.80) + 3
55.20 + 3 = 58.20
A large fish tank is having its water drained while being weighed. After 20 gallons have been drained, the tank weighs 1,909 pounds. After 50 gallons have been drained, it weighs 1,660 pounds. Let w be the weight of the tank and let g be the number of gallons drained. Write a linear equation for w in the terms of g.
Answer:
[tex]w=-8.3g+2075[/tex]
Step-by-step explanation:
Let the x axis represent the gallons g
and y axis represent the weight of the tank w.
So, the first point on the plane will be [tex](20,1909)[/tex]
and the second point will be [tex](50,1660)[/tex]
The line between these points will be
[tex]w-1909=\dfrac{1660-1909}{50-20}(g-20)\\\Rightarrow w-1909=-\dfrac{249}{30}(g-20)\\\Rightarrow w-1909=-\dfrac{83}{10}(g-20)\\\Rightarrow w=-\dfrac{83}{10}g+\dfrac{83}{10}\times 20+1909\\\Rightarrow w=-\dfrac{83}{10}g+2075\\\Rightarrow w=-8.3g+2075[/tex]
The relationship between the weight and gallons of the tank is [tex]w=-8.3g+2075[/tex]

Most dogs fail to become service dogs. In a recent training class, only 7 of the 15 dogs were certified as service dogs. What percent of dogs became certified service dogs, rounded to the nearest percent?
Answer:
46.667%
Step-by-step explanation:
Percentage of certified service dogs = 7/15 × 100%
Percentage of certified service dogs = 700/15 %
Percentage of certified service dogs = 46.667%
47%(to the nearest percent)

What is the x-intercept of the following equation? 4x + 2y = 12
Answer:
3
Step-by-step explanation:
On their most recent 8-mile training run, Pepe averaged a speed of 12 of a mile in 4.5 minutes, while Paula averaged 34 of a mile in 7.5 minutes.
How many minutes did it take the faster runner to finish the 8 mile run
Answer:
1.78 min
Step-by-step explanation:
so first you have to figure out the fastest runner
pepe 12 miles in 4.5 minutes
and paula ran 34 miles in 7.5 minutes
if you divide miles by minutes you get how many miles they ran in one minute
12/4.5=~2.67
34/7.5=~4.53
So you can see that paula is faster
if she ran ~4.5 miles in a minute then it would take her ~1.78 minutes to run 8 miles
they're both super humans though like woah
Daryl measures the angle of elevation to be 62 degrees. Frances measures the angle of elevation to be 54 degrees. if the two enthusiasts are 28m apart, how far off the ground is the helicopter.
Answer:
The helicopter is 27.38 m far off the ground
Step-by-step explanation:
The drawing shown in the image below has all the measures and variables needed to solve the problem.
We need to find R, the height of the helicopter. We'll use the law of sines to find the length of side a.
[tex]\displaystyle \frac{28}{\sin X}=\frac{a}{\sin 54^\circ}[/tex]
The angle X is the measure needed to complete 180°:
X = 180° - 54° - 62° = 64°
Solving for a:
[tex]\displaystyle a=\frac{28}{\sin 64^\circ}\cdot \sin 54^\circ[/tex]
Calculating:
a = 31.11 m
Now using the sine ratio in the right triangle to the left side:
[tex]\displaystyle \sin 62^\circ=\frac{R}{a}[/tex]
Solving for R:
[tex]R=a\sin 62^\circ[/tex]
R=31.11*0.88
R = 27.38 m
The helicopter is 27.38 m far off the ground
If Triangle PQR ~ Triangle SQT, Find the value of x.
Answer:
x = 15
Step-by-step explanation:
Given that ∆PQR ~ ∆SQT, therefore their side lengths are proportional to each other.
Thus:
[tex] \frac{PQ}{SQ} = \frac{PR}{ST} [/tex]
PQ = (x + 5) + 8 = x + 13
SQ = 8
PR = 21
ST = x - 9
Plug in the values
[tex] \frac{x + 13}{8} = \frac{21}{x - 9} [/tex]
Cross multiply
[tex] (x + 13)(x - 9) = 8*21 [/tex]
[tex] x(x - 9) +13(x - 9) = 168 [/tex]
[tex] x^2 - 9x + 13x - 117 = 168 [/tex]
[tex] x^2 + 4x - 117 = 168 [/tex]
Subtract 168 from both sides
[tex] x^2 + 4x - 117 - 168 = 0 [/tex]
[tex] x^2 + 4x - 285 = 0 [/tex]
Factorize
[tex] x^2 + 19x - 15x - 285 = 0 [/tex]
[tex] x(x + 19) - 15(x + 19) = 0 [/tex]
(x + 19)(x - 15) = 0
x = -19 or x = 15
Answer:
x = 15
Step-by-step explanation:
x+13/9 = 21/x-9
x^2+4x−117=168
x^2+4x−285=0
(x−15)(x+19)=0
x=15
it cannot be a negative number so x cannot be -19

Bader gave away 24 of his toy cars. Which integer shows the change in the number of toy cars he has?
Answer:
The integer that shows the change in the number of toy cars Bader has is -24.
Explanation:
Think of it like a math problem, when you take away from your own amount, (in this case, his cars) you're subtracting from the original amount of things you had. The symbol for subtraction is also "-", so with that information it's a bit self explanatory to know which answer is correct.
in a class 60% of the students are girls there are are 24 girls in the class how many boys are in the class
Answer:
16
Step-by-step explanation:
Let s represent all students in the class
.60(s) = 24 This equation means that 60% of students are the 24 girls in class.
Solve for s: s = 24/.60 = 40 There are 40 students in the class
Now to find how many boys are in the class, subtract 24 from 40
40 - 24 = 16
There are 16 boys in the class
Girls=60% of x
so girls 60/100
so left 40%which are boys and girls are given which is 24
students are girls and given they are 24
So total students X= total girls+ total boys
X = (60/100)*X+24
X - (60/100)*X = 24
(40/100)*X = 24
X = (24*100)/40.
X = 60
so there are 60 boys

Y=-2x-4
y = 3x+ 3
Answer:
two solutions
1.x=-7/5;y1=6/5
2.x=-7/5;y2=-6/5
Step-by-step explanation:
y=-2x-4
y=3x+3
-2x-4=3x+3
-5x=7
x=-7/5
y1=14/5-4=(14-20)/5=6/5
y2=-21/5+3=(-21+15)/5=-6/5
Answer:
2 solutions
Y= -6/5, -7/5

2. Find the GCF from the two numbers, and rewrite the sum using the
distributive property.
A. 12.+18
B.42+14
C.36+27
9514 1404 393
Answer:
1. (rose bunches, lily bunches) ∈ {(2, 3), (4, 6), (6, 9), (8, 12)}. The least is (2, 3).
2. 6(2+3); 14(3+1); 9(4+3)
Step-by-step explanation:
I like Euclid's algorithm for finding the greatest common factor (GCF): divide the larger number by the smaller, and note the remainder. If the remainder is zero, the smaller is the GCF; if not, use the remainder in place of the larger number and repeat.
__
1. The GCF of 8 and 12 is 4, so the least common multiple is ...
LCM(a, b) = ab/GCF(a, b)
LCM(8, 12) = 8·12/4 = 24
24 roses is 2 bunches; 24 lilies is 3 bunches. Up to 8 bunches of roses can be ordered to keep the number less than 100.
The florist could have ordered these numbers of bunches (roses, lilies):
(2, 3), (4, 6), (6, 9), (8, 12)
The least order is 2 bunches of roses and 3 bunches of lilies.
__
2.
A. GCF = 6, so the factored form is 6(2+3)
B. GCF = 14, so the factored form is 14(3+1)
C. GCF = 9, so the factored form is 9(4+3)
