Each bag of cookies contains x cookies. At the start, Jude has 16 bags of cookies and 5 extra cookies. Elias has 8 bags of cookies and 4 extra cookies. If Elias doubles the number of cookies he has, how many more cookies will he have than Jude?
Answer:
3
Step-by-step explanation:
J = 16 bags + 5
E= 8 bags +4
If E doubles his cookies, he has 16 bags and 8 extra cookies.
They both have the same amount of bags. 8-5= 3 extra

0.9/0.5 = a/10 Plz help
Answer:
18
Step-by-step explanation:
10/0.5 = 20
20 * 0.9 = 18
Answer:
a = 18
Step-by-step explanation:
Step 1: Cross-multiply.
[tex]0.5 * a = 10*0.9[/tex] [tex]0.5a =9[/tex]Step 2: Divide both sides by 0.5
[tex]\frac{0.5a}{0.5} =\frac{9}{0.5}[/tex] [tex]a = \frac{90}{5}[/tex] [tex]a = 18[/tex]Step 3: Check if solution is correct.
[tex]\frac{0.9}{0.5}=\frac{18}{10}[/tex] [tex]\frac{9}{5} =\frac{18}{10}[/tex] [tex]\frac{18/2}{10/2} =\frac{9}{5}[/tex][tex]\frac{9}{5} =\frac{9}{5}[/tex]Therefore, a = 18.

Answer:
-5/14
Step-by-step explanation:
2/7 times 2 to get the denominator to be 14 since adding and subtracting fractions require the same denominator. 2/7 times 2 = 4/14. -9/14+4/14=-5/14.
make them the same denominator
[tex] \frac{2}{7} \times \frac{2}{2} = \frac{4}{14} [/tex]
[tex] \frac{ - 9}{14} + \frac{4}{14} = \frac{ - 5}{14} [/tex]
Ashley and Keely shared some Hershey Kisses in the ratio of 5:2. If Keely had 12 Hershey Kisses, how many did Ashley have?
Answer:
Ashely had 30 kisses! Muah!
Step-by-step explanation:
Ratio of Ashely to Keely is 5 : 2 and we know Keely had 12. Keely represents the 2 in this ratio, and how do we get from 2 to 12? We multiply by 6. We have to multiply by 6 on the other side too then. 5 times 6 is 30, so Ashely had 30 hershey kisses.
In real life, not in ratio form, Ashely had 30 kisses and Keely had 12.

Answer:
a) 191 yards
b) 40 yards
c) 1.5 minutes
Step-by-step explanation:
Given:
ΔPQR is a right triangle with the right angle at Q
PQ = 40 yards; QR = 70 yards
M is the midpoint of PR
jogging rate is 150 yd/min
Find:
a) the perimeter of ΔPQR to the nearest yard
b) QM to the nearest yard
c) the time to jog the path PQMRQP to the nearest tenth minute
Solution:
a) The length of PR can be found from the Pythagorean theorem:
PR² = PQ² +QR²
PR² = 40² +70² = 6500
PR = √6500 ≈ 80.62 . . . . yards
Then the perimeter is ...
perimeter = PQ +QR +PR = 40 +70 +80.62 ≈ 191 yards
__
b) Segment QM divides triangle PQR into two isosceles triangles: PMQ and RMQ. The lengths MP, MQ, and MR are all equal to half the length of PR.
QM = PR/2 = (80.62 yd)/2 = 40.31 yd
QM ≈ 40 yd
__
c) The segments of path PQMRQP can be grouped to simplify the computation of the path length
PQMRQP = PQ +QM +MR +RQ +QP = PQ +(PQ +QR +(QM +MR))
Since QM +MR = PR, the length in the outer parentheses is the perimeter of the triangle. Then the jogger's total path length is ...
PQ + perimeter(ΔPQR) = 40 yd +191 yd = 231 yd
The time it takes to jog that path is ...
time = distance/speed
time = 231 yd/(150 yd/min) = 1.54 min ≈ 1.5 min
It takes about 1.5 minutes.

The graph of a linear function has a slope of 5 and passes through the point (2,5). What
is the y-intercept of the graph of the function?
Answer:
-5 is the y intercept.
Step-by-step explanation:
Ok, lets do the steps in order.
1) Make a point-slope form equation.
We know that the format of it is y - y1 = slope(x - x1), so we know have to substitute our information in the equation.
y - 5 = 5(x - 2)
2) Convert our point-slope form equation into slope intercept form, and solve for the y-intercept.
y = slope(x) + b... right? So we now have to do math.
Distribute the right side of the equation to get :
y - 5 = 5x - 10
Now cancel out the -5, and then subtract on both sides.
y = 5x - 5
And -5 is your y intercept :)
Hope this helps! Mark me brainliest :)

Suppose line g is the line with equation y=x. Given A(9,-5), B(6,3), and C(-1,-6), what are the coordinates of the vertices of A'B'C' for the reflection?
(type an ordered pair)
A'=___
B'=___
C'=___
Answers:
A ' = (-5, 9)
B ' = (3, 6)
C ' = (-6, -1)
=====================================================
Explanation:
When reflecting over the line y = x, we swap the locations of the x and y coordinates. For example, the point (5,7) becomes (7,5)
This means we have the following reflections
A(9,-5) moves to A ' (-5, 9)B(6,3) moves to B ' (3, 6)C(-1,-6) moves to C ' (-6, -1)This operation is commonly done when determining the inverse of a graph. This is because the inverse basically undoes everything the original function applies. So this "backwards" nature of things means that x becomes y and vice versa.

Mary spent three fourths of her allowance at the mall. One half of that was spent on snacks. If Mary’s allowance was thirty dollars, how much did she spend on snacks?
Answer:
$11.25
Step-by-step explanation:
Divide 30 by 4
30/4=7.50
multiply by 3
7.5*3=22.50
22.50 is 3/4 of her allowance
divide that by half to get how much she spent on snacks.
22.50/2=11.25

mrs. williams is deciding between two field trips for her class. The science center charges $225 plus $6 per student. The dino discoverry museum simply charges $11 per student. For how many students will the science center charge less than the dino discovery museum?
Answer:
Step-by-step explanation:
let x = number of students
Science Center will charge total of 135 + 3x
Dino Discovery Museum will charge total of 6x
for what x the Science Center charge less than the Dino Discovery museum that is
135 + 3x < 6x
135 < 6x - 3x
3x > 135
x > 135/3
x > 45
The Science Center charge less than the Dino Discovery museum for more then 45 students.
45students will the science center charge less than the dino discovery museum
What is Algebra?
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout practically all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.
Suppose x is the number of Students
Total fees for Science Center will be,
135+3x.
Total fees for the Dino Discovery Museum will be 6x.
The Science Center charges a lower price than the Dino Discovery Museum for what x.
135 + 3x < 6x
135 < 6x - 3x
3x > 135
x > 135/3
x > 45
Hence, For classes with more than 45 Students, the Science Center charges less than the Dino Discovery Museum.
