Answer:
x = 5
Step-by-step explanation:
1x + 20/2 = 3x
subtract 1x
1x -1x + 20/2 = 3x -1x =
20/2 = 2x
Identify
20/2 = 20 divided by 2 = 10
10 = 2x
divide by 2
10/2 = 2x/2

Janelle graphed a line through (−6, 5) that had a slope of −79. What is the y-coordinate of a point on the line that has an x-coordinate of 3?
Answer:
The value of the y-coordinate is -706
Step-by-step explanation:
The equation of a straight line is;
y = mx + c
where m is slope and c is t-intercept
Given the slope, we can write the equation as;
y = -79x + c
we need to get c
Just put in the x and y values of the given point
X = -6 and y = 5
5 = -79(-6) + c
5 = 474 + c
c = 5-474 = -469
So the complete equation of the line would
be ;
y = -79x - 469
To get the y-coordinate of the point, just insert the x value into the equation;
y = -79(3) - 469
y = -237 - 469 = -706
how far would a 4.0 cm tall object be located from a reflecting surface with a focal lenght that is equal to 5 cm if it is to create an image seen 15 cm behind the mirror. Determine the image size
Answer:
HERE IS YOUR ANSWER
Step-by-step explanation:
Use the mirror equation:
1/di + 1/do = 1/f
where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)
Substitute and solve for do.
1/do + 1/(-10 cm) = 1/(15 cm)
1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)
do = 6 cm

Write fractions for points A and B on the number line. (yup, I'm dumb)
Answer:
2/6 = A and 5/6 =B
Step-by-step explanation:
the line is split into 6 segments. so this means each little line is 1/6. if each line is 1/6, 2 lines, which is A, is 2/6 and 5 lines is 5/6. just multiply 1/6 * th number of lines from the start of the line to the letter
The fraction for point A on the number line will be 2/6 and the fraction for point B will be 5/6 respectively.

if someone helps me on this I'm giving them a lot of points,
Answer:
the distance from Fresno to San Francisco on the second map is 75cm
Step-by-step explanation:
The scale on the first map is 1 cm to 20 km
The distance from Fresno to SanFrancisco is 15 cm
1cm/20km = 15cm
The scale on the second map is 1 cm to 100 km.
1cm/100km = x
X= 15cm*100km/20km *1cm/1cm
X=15cm *5
X= 75 cm

Can you please help me with the question please
Answer:
34.1 minutes
Step-by-step explanation:
distance= 2miles,time=11 minutes
pace=velocity
velocity= distance/time
V= (2/11) miles/minutes
since the pace is maintained. then,
time taken to run 6.2 miles would be
time=distance/velocity
T= 6.2miles/(2/11)miles/minutes
T= [(6.2×11)/2]minutes
T= 34.1 minutes.

PLS ANYBODY HELP ME ON THIS 20 points
Answer: No, he is incorrect
Step-by-step explanation:
No, he is incorrect. Using a number line to model thirds means that each space that is 1/3 should be divided into 3 parts, not 2 parts. 6 parts divided into 3 groups gives 2 parts out of 9 parts total, so the answer is 2/9.

Joanne has 20 books on crafts and cooking. she has 6 more cookbooks than craft books. how many of each does she have?
Answer:
Crafts books: 7
Cookbooks: 13
Step-by-step explanation:
Let x be the crafts book
Let y be the cookbooks
Solve for x:
Plug x and y in: x + y = 20Re-write: y = x + 6Plug in x + 6 instead of y: x + x + 6 = 20Combine like terms: 2x + 6 = 20Subtract 6 from each side, so it now looks like this: 2x = 14Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7Solve for y:
Re-use an equation from above: y = x + 6Plug in the value of x: y = 7 + 67 + 6 = 13So, y = 13I hope this helps!
Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many baseball cards remain in Ryan's collection? 127 cards 90 cards 117 cards 126
Answer:
117 cards
Step-by-step explanation:
Total number of cards in the collection of Ryan = 216
Number of cards given to his brother = ⅓ of 216 = ⅓ × 216 = 216/3 = 72
Number of cards given to his friend at school = 27
Number of baseball cards that Ryan has remaining = 216 - (72 + 27)
= 216 - 99
Number of cards remaining = 117 cards

Find m angle MOP if m angle MON =4x+9 and m angle MOP =3x-3
Answer:
33
Step-by-step explanation:
Measure of ∠MOP is equals to 71.7°.
What are supplementary angles?
" Supplementary angles are those angles whose sum is equals to 180°."
According to the question,
∠MOP = 3x - 3
∠MON = 4x + 9
As ∠MOP and ∠MON has common arm OM.
Therefore, ∠MOP and ∠MON are supplementary angles.
As per definition of supplementary angles we have
∠MON + ∠MOP = 180°
Substitute the value of ∠MOP and ∠MON we get,
4x + 9 + 3x - 3= 180°
⇒7x - 6 = 180°
⇒7x = 174
⇒ x = 24.9 (round off)
Substitute the value of x in measure of ∠MOP we get,
∠MOP = 3(24.9) -3
= 71.7°
Hence, measure of ∠MOP is equals to 71.7°.

Answer:
4
Step-by-step explanation:
You would use a^2+b^2=c^2
a^2+3^2=5^2
a^2+9=25 subtract nine from both sides
a^2=16
find the square root of 16 which is 4
so the other side of the triangle is 4
Answer:
4 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the length of the 3 rd side, then
x² + 3² = 5²
x² + 9 = 25 ( subtract 9 from both sides )
x² = 16 ( take the square root of both sides )
x = [tex]\sqrt{16}[/tex] = 4
The third side is 4 cm
